[00:48:11] | fuxxy: | that could be a possible reason, mythfrontend's CPU usage is at 115% in 'top' |

[01:08:02] | fuxxy_: | jamesd, sorry bout that, was testing a theory. |
[01:08:29] | fuxxy_: | jamesd, I read online that poor signal can cause that, and I unplugged my cable modem (first split on the line) and plugged it in directly to the hdhomerun. |

[01:11:39] | jamesd: | did it help any? |
[01:11:51] | fuxxy_: | jamesd, nope. |
[01:12:02] | jamesd: | do you have an nvidia video card? |
[01:12:21] | fuxxy_: | jamesd, yes. I'm also using the nvidia binary drivers |
[01:13:15] | fuxxy_: | jamesd, This is supposed to be the HD stream for my local news channel. |
[01:13:48] | fuxxy_: | I notice that my CPU usage by mythfrontend is normally 20–30%, and when I tune this stream, it shoots up to 115% |
[01:14:37] | jamesd: | did it work better before? or is this your first install? |
[01:14:38] | fuxxy_: | I'm also not sure if it matters or not, but mythtv-setup channel scan didn't find this stream. I manually configured it in mysql. |
[01:15:10] | fuxxy_: | jamesd, this is technicaly the first install, although there have been a few reinstalls on this same machine :) |
[01:15:27] | fuxxy_: | I've never been able to tune this channel before, mythtv-setup's scan has always missed it. |
[01:16:02] | jamesd: | do you only have excessive cpu usage on this channel or does it effect all channels |
[01:16:39] | fuxxy_: | jamesd, That I can't be conclusive about. I havent monitored cpu usage before. |
[01:17:13] | jamesd: | well change the channel.. if it works on all the others, just live with it and hopefully someone will fix the issue later |
[01:17:44] | fuxxy_: | jamesd, :) but I need my Chuck/Heroes in HD! |
[01:18:11] | jamesd: | you never said it didn't work.. you just said it uses excessive cpu.. |
[01:18:26] | fuxxy_: | I have a strong suspicion that this is the only HD channel I've been able to tune, you think the issue may be related to network saturation? |
[01:18:43] | fuxxy_: | the hdhomerun only has 100mbit NIC |
[01:19:38] | jamesd: | its not the network connection.. hdtv is only 7GB per HOUR... but it could be another issue like cpu issue... i'm not a myth expert... |
[01:19:44] | fuxxy_: | hmm. |
[01:20:35] | fuxxy_: | I wonder if I watch a local file in HD if it wil recreate the CPU situation. |

[01:44:15] | t0ny-p40: | I'm having troubles changing channels. I type 490, but soon as I get to 9 it changes the channel to 49. |

[01:46:25] | fuxxy_: | it played just fine until it went to commercial, and now that it's past the commercials, it's fine again. |
[01:46:58] | Saviq: | fuxxy_: so what's the problem? ;) |
[01:47:07] | fuxxy_: | Saviq, :) |
[01:47:19] | fuxxy_: | CPU is all over the board. |
[01:47:28] | fuxxy_: | right now, 112% |
[01:47:38] | fuxxy_: | and occaisionally goes down to 80% |
[01:47:48] | fuxxy_: | it's weird. this is a P4 2.8Ghz |
[01:49:15] | fuxxy_: | It shoud handle HDTV a LOT better than what it currently is. |
[01:51:03] | iamlindoro__: | A P4 2.8 Ghz will *barely* manage US broadcast HD in linux. and even still you may need Xvmc. |
[01:51:44] | iamlindoro__: | So I'd say the topping out that you're seeing is likely just about right. |

[02:13:37] | fuxxy_: | iamlindoro__, so let me verify my logic – the whole issue of slow CPU should only affect playback, if I record using that stream, the recorded program shouldn't be affected ? |
[02:13:39] | clever: | yeah your using more then mine, but i find it sucks up more memory after i start playing(and holds on to it) |
[02:13:56] | jamesd: | clever, check out the cached: line its disk cache and is a good thing. |

However, it also clearly states that it is NOT backwards compatible with existing ATSC tuners. I stand corrected. |

[04:43:42] | iamlindoro__: | OK, I'm going to bed so I don't have a whole lot of time to argue with you. First off, nobody ever said current ATSC tuners could use h.264. Second off, your story about "having the PS specs in front of you" is nonsense, you said that there was no such thing as an MPEG container. Third, and finally, MPEG PS most certainly DOES allow for h.264. |
[04:44:05] | Lexridge: | iamlindoro: Anyway...just wanted to get that off my chest. I like to clear the slate when I'm wrong. I'm Just sorry I wasted so much of my time, and yours, discussing something I was not experienced with. |
[04:44:17] | iamlindoro__: | I know you are trying to save face or whatever, but you REALLY need to let if freaking drop, because you are only embarassing yourself. |
[04:44:25] | Lexridge: | not according to this: http://en.wikipedia.org/wiki/Comparison_of_container_formats |
[04:44:43] | iamlindoro__: | It is incorrect. Look up "EVOB" |
[04:44:56] | iamlindoro__: | EVOB is the MPEG PS container used on HD-DVD, a format that uses h.264. |
[04:45:37] | iamlindoro__: | and as for " I have zero experience in TS streams." You are the one claiming to be an "expert in your field," broadcasting. YOUR STATION ENCAPSULATES DIGITAL BROADCASTS IN TS STREAMS. |
[04:45:49] | iamlindoro__: | Now STOP. TALKING. |
[04:46:01] | Lexridge: | we don't encapsulate anything yet, because we are not yet broadcasting in digital |
[04:46:21] | Lexridge: | we are still racking the equipment |
[04:46:34] | iamlindoro__: | So that two years spent "on this project" must not have covered first-day digital broadcast theory, then |
[04:47:10] | iamlindoro__: | Are you really going to start an argument with me again, knowing how wrong you've been thus far? |
[04:48:08] | Lexridge: | no at all. I'm trying to tell you I was wrong, and wasted yours and my time. can you not accept that? |
[04:48:32] | iamlindoro__: | I can. But stop making up excuses and stories that only further expose your BS. |
[04:49:04] | Lexridge: | you have to realize that small station employees wear many many hats and work lots of 16 hour days. |
[04:49:15] | iamlindoro__: | If you had "had the MPEG PS specs" in front of you, then you wouldn't have thought you can't do h.264 with it. |
[04:49:45] | iamlindoro__: | I'll invite our intrepid readers to read the logs from last night and leave to THEM whether you even knew what a container was, let alone what is permitted in which. |
[04:50:43] | Lexridge: | I have ran every mpeg2 encoder I legally have, both linux and windows, and none, not one allow me to use an h264 stream inside a mpeg2ps container. AVIDemux, CarbonCoder, TMPGENC, and Telestream...none allow it. |
[04:51:22] | Lexridge: | I have to use a TS stream in order for these programs to let me choose an h264 codec. |
[04:51:23] | iamlindoro__: | Lexridge, So? You don't have encoders capable of creating EVOBS. |

[04:51:54] | iamlindoro__: | So now instead of "having the specs in front of you," your reasoning for your belief is that your random softwares can't do it? |
[04:52:09] | iamlindoro__: | Lexridge, apparently not. blu-ray doesn't use PS. |
[04:52:14] | iamlindoro__: | HD-DVD does. |
[04:52:33] | Lexridge: | you just said it does use ps |
[04:52:34] | wagnerrp: | so were back it seems |
[04:52:46] | iamlindoro__: | You just keep making up lies, and it just makes you seem stupider when caught by people who know what they're saying. |
[04:53:02] | iamlindoro__: | Lexridge, I most certainly did not. "<iamlindoro__> EVOB is the MPEG PS container used on HD-DVD, a format that uses h.264." |
[04:53:28] | Lexridge: | oh, the format that was killed. Okay. sorry. |
[04:53:55] | iamlindoro__: | So waht if the format didn't survive? The container is still perfectly valid and is totally apart from the media. |
[04:54:08] | Lexridge: | I do not want another senseless argument. Just just agree to disagree. okay? |
[04:54:41] | Lexridge: | er....lets just agree to disagree...okay? |
[04:54:52] | iamlindoro__: | What is it in particular you disagree with? As everything I've said is 100% fact. You don't *get* to disagree with facts. They are just... facts. |

[04:57:03] | Lexridge: | I have a feeling EVOB is probably a patiented format owned exclusively by Sony, and not part of the mpeg standard. |
[04:57:18] | wagnerrp: | EVOB is used by HDDVD, not a sony product |
[04:57:26] | Lexridge: | or whoever. |
[04:57:36] | wagnerrp: | microsoft or toshiba perhaps |

[04:58:01] | Lexridge: | g'nite and happy thanksgiving to you |
[04:58:11] | wagnerrp: | AFAIK, yes, VOB and EVOB are modifications to the original mpeg2 container spec |
[04:58:29] | wagnerrp: | whether they are patented or not, i have no idea |
[04:59:27] | Lexridge: | most mpeg variations are patiented, which is why you cannot play them under all Fedora dists, and many other dist...out-of-the-box. |
[04:59:50] | Lexridge: | everyone is afraid of being sued. |
[05:00:23] | wagnerrp: | well several parts of the original spec are patented |
[05:00:31] | Lexridge: | yes |
[05:00:34] | fuxxy_: | I hate it when I go through the trouble of installing a new UPS, just to find out it's bad. |
[05:00:35] | wagnerrp: | im saying i dont know if the modified forms have any additional patents |
[05:00:50] | Lexridge: | nor do I, but it's a pretty good assumption |
[05:00:53] | wagnerrp: | what is there to install on a UPS? |
[05:01:04] | wagnerrp: | you plug it in and go |
[05:01:16] | Lexridge: | I had to install s/w for my ups |
[05:01:40] | Lexridge: | it did support linux, but I had to download the s/w from their site. |
[05:01:42] | fuxxy_: | wagnerrp, I like to keep the clutter to a minimum. |
[05:01:43] | wagnerrp: | well any shutdown software you install is going to work for the replacement UPS as well |
[05:02:32] | Lexridge: | what kind of ups is it? |
[05:03:38] | fuxxy_: | APC |
[05:03:53] | fuxxy_: | I was trying to go from a dump interface to a smart interface |
[05:04:12] | Lexridge: | and you are sure the UPS is bad? |
[05:04:19] | fuxxy_: | put the ups in, ran all the wires nice, plugged it all in, did a self test, and the UPS shat itself. |
[05:04:24] | fuxxy_: | Lexridge, uh, yeah. |
[05:04:51] | fuxxy_: | It's supposed to be a 700VA, and it bitched about overload and shuts down with just the CPU plugged in. |
[05:05:00] | fuxxy_: | sorry, language. |
[05:05:07] | Lexridge: | oh, well, when you exchange it (hopefully locally for you) keep the cables, and have them just keep the cables out of the new box. |
[05:05:23] | Lexridge: | then you wont have to re-run anything |
[05:05:32] | fuxxy_: | Lexridge, yep. |

[05:06:17] | wagnerrp: | well, what kind of machine do you have running on it? |
[05:06:46] | wagnerrp: | 700VA is only around 400W |
[05:06:54] | wagnerrp: | its feasible a single machine could pull that |
[05:07:13] | wagnerrp: | my pair hooked up to my UPS idle around there |
[05:08:08] | fuxxy_: | wagnerrp, it's power hungry, but not that much. I had it running on a 500VA |
[05:08:45] | wagnerrp: | ok |
[05:09:03] | wagnerrp: | the other problem is the initial power-on spike |
[05:09:03] | Lexridge: | I'm amazed how little power I draw from mine. Its a 1000VA, with computer (5 HDDs/dual core/nivia6800), 19" monitor, 27" TV and 6 channel amp and it is only putting out 250 watts ATM |
[05:09:21] | fuxxy_: | wagnerrp, and that's not an issue either. |
[05:09:22] | wagnerrp: | but APC usually makes quality parts, capable of handling such a thing |
[05:09:44] | fuxxy_: | I did the self-test after the system was turned on. Before the filesystems were mounted RW, mind you. |
[05:10:02] | wagnerrp: | a 27" CRT will pull 250W on its own, i assume thats an LCD? |
[05:10:35] | clever: | i never put my CRT on the ups |
[05:10:43] | Lexridge: | no, it's a CRT! Humm, maybe it's a 25" |
[05:10:48] | clever: | it allways kills the thing in 2 seconds(when i need it most to properly shutdown) |
[05:10:53] | wagnerrp: | isnt your UPS home built? |
[05:11:02] | Lexridge: | IT claims I have 6 minutes of runtime. |
[05:11:17] | clever: | my ups is running on 4 12v baterys, but when they are getting low, it cant handle the crt |
[05:11:17] | Lexridge: | mine home built? No! |
[05:11:25] | wagnerrp: | no, clever's |
[05:11:29] | Lexridge: | nice! |
[05:11:47] | wagnerrp: | besides, a 1000VA running at 250W (~400VA) should have upwards of half an hour of runtime |
[05:12:07] | Lexridge: | not with the TV plugged into it. Without, I have like 20 minutes. |
[05:12:29] | wagnerrp: | ive got my backend and my desktop plugged into a 900VA |
[05:12:33] | Lexridge: | It's off now, and the UPS is telling me 16 minutes. |
[05:13:03] | wagnerrp: | both dual cores, 3 graphics cards, 6GB or memory, 3 monitors, and 14 drives between them |
[05:13:04] | Lexridge: | so I gain 10 minutes with the CRT turned off. |
[05:13:09] | wagnerrp: | i still get about 20 minutes on battery |
[05:13:53] | wagnerrp: | on idle, under load, it cuts to 15m or so |
[05:14:04] | Lexridge: | mine just creeped up a bit now to 18 minutes. |
[05:14:11] | Lexridge: | turning CRT back on |
[05:14:12] | wagnerrp: | so a 1000VA should do considerably more than that |
[05:14:35] | Lexridge: | you have Three GFX cards!?!? HS! |
[05:14:42] | wagnerrp: | unless either it, and the battery, are getting old |
[05:14:52] | Lexridge: | I just bought it about 2 months ago. |
[05:15:10] | wagnerrp: | or you have some poor power factor going on there, and the UPS isnt designed to properly measure load |
[05:15:16] | wagnerrp: | HS? |
[05:15:23] | Lexridge: | holyshit |
[05:15:25] | Lexridge: | lol |
[05:15:41] | wagnerrp: | three graphics cards between two machines |
[05:15:49] | clever: | i have a pair of gfx cards in my main system, but i dont use the 2nd much |
[05:15:58] | wagnerrp: | and the two in my desktop run three screens, not SLI |
[05:16:13] | wagnerrp: | one is nice (but old), the other is middling (and also old) |
[05:16:15] | Lexridge: | oh, okay. I jsut have one computer and one gfx card, amp, 19" LCD and CRT into mine. |
[05:16:44] | wagnerrp: | brand of UPS? |
[05:17:17] | Lexridge: | It's branded Nexxtech, but it's built by someone else...lemme check...I think it's on the bottom of the unit who actually makes it. |
[05:18:21] | TomasuAway is now known as TomasuDlrrp | |
[05:18:43] | Lexridge: | CyberPower systems actually makes it |
[05:18:55] | Lexridge: | It's a UUPS1000LCD model |
[05:19:57] | Lexridge: | Got a great deal on it....closeout at CC for $70 |
[05:20:14] | wagnerrp: | yeah, i got my 900VA CPS for $60 |
[05:20:28] | Lexridge: | Tigerdirect still sells them (under the CyberPower brand) for $170 |
[05:20:45] | Lexridge: | I love a great deal! |
[05:21:15] | Lexridge: | Now, my backend is running on a APC 300VA, but it's only by itself on that one. No monitors or anything. |
[05:21:16] | wagnerrp: | seems a decent enough UPS |
[05:21:33] | Lexridge: | I'm happy with it, especially with the linux support. |
[05:21:48] | Lexridge: | I didn't expect that when I bought it |
[05:21:51] | wagnerrp: | i cant imagine my lower spec'd UPS from the same brand would have better run time |

[05:24:25] | wagnerrp: | it allows you to have multiple machines connected to one UPS |
[05:24:37] | wagnerrp: | or have machines on non-smart UPSs like your 300VA unit |

[05:25:17] | Lexridge: | oh, okay. At work, I just bought an APC 30kW UPS that does this. IT will run the datacenter for 30 minutes at 30kW. Can't wait to get it operational. :) |
[05:26:10] | wagnerrp: | anyway, the USB port on mine is really just a serial bridge, that isnt compatible with freebsd |
[05:26:11] | gizmobay (gizmobay!n=gizmobay@VDSL-130-13-22-243.PHNX.QWEST.NET) has quit (Client Quit) | |
[05:26:14] | wagnerrp: | not that ive found anyway |
[05:26:32] | wagnerrp: | so i have both of these systems slaved off my firewall on an APC UPS in the basement |
[05:27:07] | Lexridge: | nice setup. |
[05:27:18] | wagnerrp: | i *should* be able to use the serial port to access it, if only either of these machines had a serial port |
[05:27:40] | Lexridge: | but it signals all the units via ethernet when to shutdown using NUT? |
[05:27:51] | wagnerrp: | correct |
[05:27:58] | Lexridge: | I like that! |
[05:28:09] | wagnerrp: | it expects that you are going to be using UPSs that will shutdown completely |
[05:28:19] | shadash: | have you heard of the parallel clusters with Xen "zones" on them? That is a cool network |
[05:28:40] | Lexridge: | Xen? are you talking VMs? |
[05:28:47] | wagnerrp: | so you can set your UPS and BIOS to boot on power return |
[05:28:48] | shadash: | a complete virtual contained network on a cluster |
[05:29:03] | wagnerrp: | but dumb UPSs are a bit trickier |
[05:29:04] | shadash: | just something cool |
[05:29:36] | Lexridge: | That would be very nice!! |
[05:30:31] | Mixx (Mixx!i=zxcv@d60-65-201-134.col.wideopenwest.com) has quit ("and he can gnash and grind his teeth / and compose spells - kingadroc") | |
[05:30:47] | Lexridge: | I would imagine that APC at work can do something similar. Haven't even had time to read the docs or look at the disc yet. I would think for the $27k it cost, It should do this, but perhaps I assume too much |
[05:31:44] | Lexridge: | The system weighs just shy of one ton. It cracked the ceramic tile on the floor when we rolled it in. lol |
[05:31:49] | shadash: | imagine hosting companies servers all virtually for them in a Xen "zone" on a parallel cluster. You could give the VM's and cpu power + ram that you want. and for more power all you have to do is add more nodes to the parallel cluster |
[05:32:37] | Lexridge: | very cool! |
[05:32:42] | shadash: | or in mythv terms you could have a 20ghz cpu backend |
[05:33:06] | Lexridge: | via beuwolf or just VM? |
[05:33:20] | shadash: | the vm's are on top of the cluster |
[05:33:51] | shadash: | or just 1 vm |
[05:34:05] | Lexridge: | interesting indeed! |
[05:34:10] | shadash: | ;-) |
[05:34:17] | shadash: | told you |
[05:34:22] | wagnerrp: | you COULD NOT give it a 20GHz CPU |
[05:34:28] | Lexridge: | but, ATM, my mythbackend does not need that kind of cpu horsepower. |
[05:34:35] | shadash: | you can |
[05:34:40] | wagnerrp: | you cannot magically turn parallel capability into serial capability |
[05:34:46] | wagnerrp: | it doesnt work that way |
[05:35:09] | shadash: | that's what rocks linux from the ucsd super computer center is doing |
[05:35:41] | shadash: | At least that's how I understand it to work |
[05:36:31] | wagnerrp: | well you understand wrong |
[05:36:41] | wagnerrp: | this is what i do |
[05:36:52] | shadash: | you're running a Xen VM on a parallel cluster. When you define the Xen vm you say how much ram + cpu you want |
[05:37:06] | wagnerrp: | you can give it however many number of CPUs you want |
[05:37:32] | wagnerrp: | but then its just a 10 CPU machine all running at 2GHz |
[05:37:42] | wagnerrp: | NOT a 1CPU machine running at 20GHz |
[05:37:54] | wagnerrp: | your code has to be designed to run in parallel |
[05:38:17] | wagnerrp: | the scheduler cannot magically split up code onto multiple processes |
[05:38:30] | shadash: | this is a Xen VM on top of a parallel cluster |
[05:38:47] | shadash: | I'm trying to find the link |
[05:39:08] | wagnerrp: | you can add some multithreading in the compiler, you can add some multithreading in the OOO hardware directly on the CPU |
[05:39:22] | wagnerrp: | you cannot simply split one task into multiple ones |
[05:39:39] | wagnerrp: | imagine you have a code where all you do is keep adding one to a counter |
[05:39:41] | Mixx (Mixx!i=zxcv@d60-65-201-134.col.wideopenwest.com) has joined #mythtv-users | |
[05:39:44] | shadash: | http://www.rocksclusters.org/wordpress/ check out the xen roll |
[05:39:52] | wagnerrp: | how are you going to divide that into more than one execute core |
[05:39:55] | wagnerrp: | it cannot be done |
[05:40:04] | shadash: | see what you think |
[05:40:08] | wagnerrp: | it has to function serially on just one of those CPUs |
[05:40:37] | wagnerrp: | trust me on this one, i write heavily parallel code for use on clusters for a living |
[05:40:51] | t0ny-p40: | ya shadash you can't add up multiple cpus to a single one. |
[05:41:05] | shadash: | check out the link |
[05:41:08] | t0ny-p40: | Well, you might but it would have WAY to much overhead. |
[05:41:11] | shadash: | see what you think |
[05:41:42] | wagnerrp: | i have a machine with a theoretical peak somewhere shy of 10TF as my plaything at work |
[05:41:43] | shadash: | the Xen roll is for running xen vm's on a parallel cluster |
[05:42:04] | wagnerrp: | yes, and you end up with a multiprocessor VM |
[05:42:39] | t0ny-p40: | You might be able to build a vm with multiple cpus, it its not really possible to add cpus together. |
[05:42:48] | wagnerrp: | not a single processor vm running at several times the speed |
[05:43:17] | shadash: | ahhh wait a minute... "Support for building Xen VMs on cluster nodes" |
[05:43:37] | shadash: | hmmm.... |
[05:44:21] | shadash: | I talked to one of the developers for rocks and what he told me is what I told you. But that might not be rue |
[05:44:24] | jamesd: | there are applications that allows you to offload compiles to multiple machines and use cached build data to speed things up... distcache comes to mind |
[05:44:46] | shadash: | yes I know about that |
[05:44:56] | wagnerrp: | distcc runs one compile command per box |
[05:45:09] | wagnerrp: | it doesnt split the compilation of a single file between multiple boxes |
[05:45:24] | wagnerrp: | that cannot be done |
[05:46:08] | t0ny-p40: | I can't wait till I get a tech job. I want to play with vm clusters in a datacenter. :) |
[05:46:13] | Chicago: | Hello |
[05:46:19] | jamesd: | if you need to split the compile of a single file across boxes your code is broken and needs to be rewritten into smaller pieces. |
[05:46:21] | Chicago: | Happy Thanksgiving |
[05:46:23] | Lexridge: | wagnerrp: Is this not how Seti@home works? |
[05:46:34] | t0ny-p40: | But I think I'll be working call centers for a while before that. |
[05:46:41] | shadash: | vm's are sweet |
[05:46:56] | wagnerrp: | Lexridge: seti@home splits the job into multiple discrete work packets |
[05:47:06] | shadash: | and snapshots make them cool for testing |
[05:47:06] | Lexridge: | wagnerrp: ah, okay |
[05:47:14] | wagnerrp: | each taking several hours to complete before resyncing with the rest of the group |
[05:47:20] | Chicago: | Distcc from the makers of samba is made to distribute gcc jobs. |
[05:47:30] | wagnerrp: | typically work performed on clusters resyncs once per iteration |
[05:47:32] | Lexridge: | wagnerrp: kinda like Lightwave screamernet |
[05:47:54] | wagnerrp: | with iterations typically occurring several times a second, to once every couple minutes |
[05:49:19] | wagnerrp: | same basic principle, but cluster applications usually require much higher bandwidth, higher integration, and lower latency |
[05:49:48] | wagnerrp: | applications like 'seti@home' are what is called 'embarrassingly parallel' |
[05:49:54] | Lexridge: | lol |
[05:50:03] | wagnerrp: | since the data packets can be computed with little regard for one another |
[05:50:30] | Lexridge: | not really parallel, but totally independent it would seem |
[05:50:44] | wagnerrp: | pretty much |
[05:51:10] | Lexridge: | I have a buddy that has been using seti@home for years. I have always refused to waste my cpu on it. |
[05:51:49] | wagnerrp: | stuff like ray tracing is embarrassingly parallel, each compute node needs the complete geometry, but beyond that, all ray computations are completely independent of eachother |
[05:53:21] | Lexridge: | the NewVoyages (star trek) project has talked about letting fans use their CPUs for rendering SFX projects, but I don't think that has ever came to be. Great idea however, as it is fairly popular. |
[05:54:12] | Lexridge: | oh, I guess it's now called Star Trek – Phase II FWIW |
[05:55:42] | shadash: | so I'm reading more into rocks xen clusering and it appears they just created a way to create xen vm's on a specific node of the cluster |
[05:56:20] | Chicago: | shadash: link? |
[05:56:34] | wagnerrp: | it seems like rocks is an attempt to make cheap bigiron |
[05:57:01] | shadash: | but you can tie the vm's together in a zone or container |
[05:57:07] | shadash: | http://linuxmicrosoft.wordpress.com/2008/05/0 . . . r-linux-v50/ |
[05:57:21] | shadash: | rocks is beyond sweet for setting up a cluster |
[05:58:01] | shadash: | creates a cluster in under 30 minutes depending on how many nodes you set up |
[05:58:18] | sphery: | If anyone's looking for an HDHomeRun, newegg has them on sale for $129.99 with free shipping using promo code EMCBBCJBF (saves $39) |
[05:58:30] | shadash: | already have one |
[05:58:46] | Lexridge: | sphery: does it have component inputs? |
[05:58:54] | shadash: | lets see the hdpvr sell for 129 |
[05:58:56] | Chicago: | Would any of you all know how to monitor how much memory my IVTV driver's buffers are using? |
[06:00:24] | sphery: | Lexridge: nope. It's a network-attached ATSC tuner |
[06:00:34] | t0ny-p40: | Can mythfilldatabase just fill a new video source? |
[06:00:34] | wagnerrp: | ATSC only, no analog |
[06:01:18] | clever: | Chicago: i was thinking /proc/slabinfo and 'slabtop' but that file is missing in my ivtv box |
[06:01:23] | Lexridge: | what about hte hdpvr? Component inputs? |
[06:01:53] | sphery: | t0ny-p40: you mean run mfdb so it doesn't re-download some video source? |
[06:02:06] | shadash: | check out the mythtv wiki for info on the hdpvr |
[06:02:23] | Lexridge: | ok |
[06:02:28] | Chicago: | clever: I would like to monitor them, because I blindly increased their buffer sizes and I would like to watch them while they are being used. |
[06:02:29] | sphery: | t0ny-p40: if so, see --help (specifically the --sourceid stuff in there) |
[06:02:51] | clever: | Chicago: check the debug stuff for ivtv |
[06:03:14] | Lexridge: | ah, it does support component inputs. Nice. Now I know what to ask the wife for xmas. :) |
[06:03:14] | t0ny-p40: | ahh thanks I missed that flag |
[06:03:22] | clever: | Chicago: modinfo ivtv, youll see a debug option |
[06:03:36] | Chicago: | Cool, I have slabinfo on here, and I build the kernel using SLAB... |
[06:03:50] | shadash: | hdpvr is nice hardware |
[06:04:04] | clever: | Chicago: though if the driver is sane, it will alocate the buffers once and then just use them, so slabtop wont change much |
[06:04:06] | Chicago: | So now I just need to know which one of these are the individual targets. There are at least 4 of them from modinfo ivtv I want to watch. |
[06:04:13] | Chicago: | Oh... |
[06:04:34] | Lexridge: | What is nice I could add the hdpvr to my existing mythbackend server...how cool!!! |
[06:04:47] | Chicago: | clever: I want to be able to watch the buffers in realtime (almost) and see if they correspond to the errors I see about the mpegts from my encoder. |
[06:05:09] | clever: | Chicago: then youll need to find the right bitmask for modprobe ivtv debug=mask |
[06:05:13] | clever: | or just enable everything |
[06:05:30] | shadash: | many people are waiting for .22 so an official stable version will have hdpvr support |
[06:05:41] | clever: | modprobe ivtv debug=511 # this will enable all debug output |
[06:05:51] | shadash: | and all the new nvdia driver stuff |
[06:06:50] | shadash: | some doors are going to get opened this winter for mthtv |
[06:08:21] | shadash: | what I want to do is create a custom version of Fedora 10 with Mythtv .22 on it |
[06:08:39] | wagnerrp: | like... mythdora? |
[06:08:45] | Lexridge: | what kind of "doors"? |
[06:08:59] | shadash: | yea but more up to date |
[06:09:04] | clever: | you could just throw trunk ontop of mythdora after tearing out the mythtv binarys:P |
[06:09:07] | Chicago: | clever: much fun. I think I get to upgrade to a new ivtv version on my gentoo tonight anyhow, because the 2.6.26 kernel went stable for my architecture this week... and each time I upgrade kernel, I get a brand new ivtv version. |

[06:10:14] | Chicago: | clever: I found a new tool I love. "modules-rebuild" It remembers the version of the module package which I used to build the module on the last kernel... and then just builds them for me. |
[06:10:19] | shadash: | mythdora tries to do some things that get it into trouble |
[06:10:29] | clever: | Chicago: i cant recompile lirc anymore |
[06:10:30] | Chicago: | It works real nice for things like... darn which modules do I have to build again? |
[06:10:42] | tjcarter: | Just thought I'd share with anyone considering becoming poorer in a hurry in the US: Newegg has HDHomeRun Friday only for $130 |
[06:10:44] | Lexridge: | shadash: I just downloaded F10, but need a lot of preemptive work before upgradeing from FC6, which is what my main machine is running. |
[06:10:56] | Chicago: | clever: Is there a src package on your distro? |
[06:11:10] | clever: | Chicago: the lirc source that comes with ubuntu compiles and fails to change channels on the serial blaster |
[06:11:10] | shadash: | well linux is linux underneath |
[06:11:31] | clever: | Chicago: the source i have saved that used to work, fails to compile |
[06:11:32] | tjcarter: | You probably have to sign up to be spammed to get that price, but Newegg honors "stop spamming me" requests within a couple of days. |

[06:12:30] | shadash: | I just want to put the specific needed mythtv rpms in the fedora 10 iso. Let the users configure everything else |
[06:12:31] | ** tjcarter isn't getting one (poor graduate student) ** | |
[06:12:51] | shadash: | set up anaconda to do an automated install |
[06:12:55] | Chicago: | clever: I which there were more pvr150/pvr500's for sale in the market. |
[06:12:57] | Lexridge: | where can I find a CHEAP hdmi one in to two out converter? The cheapest I can find is $200!!! Ouch!! |
[06:13:16] | Chicago: | clever: Do you build i2c in as a module? |
[06:13:29] | clever: | Chicago: i beleive so |
[06:13:36] | Lexridge: | basically I want a HDMI distribution amp. 1 in, two outs. |
[06:13:47] | clever: | i2c_core 25104 7 wm8775,cx25840,tuner,ivtv,i2c_algo_bit,tveeprom,i2c_piix4 |
[06:13:55] | tjcarter: | Lexridge: don't some HDMI switches have two outs? |
[06:14:14] | Lexridge: | tjcarter: dunno, have not found anything like that yet., |
[06:14:45] | Chicago: | clever: In the past, thing for me broke if I built i2c into the kernel * explicitly. |
[06:15:04] | clever: | Chicago: hold on, one of my scripts exploded |
[06:15:20] | Lexridge: | tjcarter: ah, using the search term "splitter" I found one for $35. Much more reasonable! |
[06:15:22] | tjcarter: | Lexridge: I don't remember where I saw it, but it was a nifty device that had two outputs (HDMI, component, s-video) and like 4 inputs (all of the above) |
[06:15:42] | tjcarter: | it was around $200, but then again, it was a lot more sophisticated than you're asking about |
[06:16:06] | Lexridge: | yea, it would be |
[06:16:21] | tjcarter: | since it would let you feed in mono + composite and get HDMI with integrated audio (albeit out the left side) |
[06:16:30] | tjcarter: | or anything on up |
[06:16:35] | shadash: | does anybody know if data recorded with the hdpvr automaicaly have commercials cut out yet? |
[06:16:49] | shadash: | or do you have to run a script? |
[06:16:56] | tjcarter: | I considered it as a good way to feed random crap into a monitor |
[06:17:04] | Chicago: | I need some help with a Rube Goldberg contraption. |
[06:17:23] | Lexridge: | shadash. It should work as with any recorded mythtv video as far as commercial detection.....right? |
[06:17:37] | shadash: | no it's different |
[06:17:59] | clever: | Chicago: ahh not a problem on my end |
[06:18:00] | shadash: | last I saw there was a script for comm flagging |
[06:18:14] | tjcarter: | anyway, I mostly popped in to let people know about the HDHomeRun for a nice price |
[06:18:16] | Lexridge: | shadash. I guess it would depend on whether mythtv supports h264 or not. |
[06:18:24] | clever: | Chicago: i2c_core is a module |
[06:18:28] | Chicago: | Here is what it looks like. linux-2.6 -> video4linux2 <-> pvr500 v4l2 -> ffmpeg -> ffserver. |
[06:18:36] | clever: | Chicago: i havent rebuilt the kernel itself |
[06:18:46] | tjcarter: | Lexridge: "active" or "powered" splitter |
[06:18:47] | shadash: | yea its one of the things the devs are working on |
[06:18:51] | Chicago: | clever: Then you probably don't have kernel headers for new drivers to compile on. |
[06:19:01] | clever: | Chicago: i have all the headers |
[06:19:21] | Lexridge: | tjcarter: First one: http://cables.cablesunlimited.com/cables/Hdmi%20Splitter |
[06:19:31] | clever: | Chicago: i can compile the new lirc, but it doesnt work |
[06:19:36] | Chicago: | It seems on linux-2.6.25, with ivtv driver v1.2.0 that mplayer cannot access the pvr500 as pvr:// or tv:// through v4l2. |
[06:19:40] | clever: | Chicago: and i cant compile the old lirc(which used to work) |
[06:19:44] | Chicago: | clever: paste the error |
[06:19:45] | tjcarter: | Lexridge: excellent, does it kill HDCP too? ;) |
[06:19:52] | clever: | Chicago: i'll have to reproduce it |
[06:20:29] | Lexridge: | tjcarter: doubtful |
[06:20:43] | shadash: | does anybody run a mac mini frontend? |
[06:21:05] | Lexridge: | shadash: I would love to, but no. It would be ideal! |
[06:21:11] | Chicago: | Does anybody care about using mplayer on pvr500/pvr150 using pvr:// tv:// syntax? |
[06:21:15] | clever: | Chicago: /media/mainlv/videos/lirc-0.8.1/drivers/lirc_dev/lirc_dev.c:245: error: implicit declaration of function ‘DECLARE_MUTEX_LOCKED’ |
[06:21:18] | clever: | and many more |
[06:21:22] | shadash: | I've got all my backend hardware sorted but am looking for the best frontend |
[06:21:44] | Lexridge: | shadash: frontends can be built rather cheaply |
[06:21:46] | tjcarter: | Lexridge: that's passive. |
[06:21:54] | tjcarter: | Lexridge: make sure you have short cable runs |
[06:21:55] | shadash: | mac mini looks like a good choice for a frontend if it can do hidf |
[06:22:09] | tjcarter: | Or plug it into a single HDMI amplifier |
[06:22:11] | shadash: | it's gotta look nice |
[06:22:22] | Lexridge: | tjcarter: what is the limit, 5 meters? |
[06:22:26] | shadash: | and be near silent |
[06:22:32] | tjcarter: | a good amp designed for long cable runs into the splitter should do it |
[06:22:34] | Chicago: | silent is nice |
[06:22:38] | tjcarter: | more hardware, but cheaper |
[06:22:39] | shadash: | mac mini seems like the best option |
[06:22:43] | Chicago: | but in the winter, they should be hot computers |
[06:22:57] | Lexridge: | shadash: Look at some of the nano-ATX or Micro-ATX MBs |
[06:23:12] | Lexridge: | shadash: several don't even have a single fan |
[06:23:30] | shadash: | yea but cheap form factors really |
[06:23:41] | shadash: | I've looked |
[06:24:18] | shadash: | seems odd that nobody has made a good frontend |
[06:24:25] | shadash: | like the mac mini |

[06:26:05] | shadash: | cya |
[06:26:10] | wagnerrp: | it should handle mpeg2 just fine |
[06:26:20] | wagnerrp: | h.264.... depends on the bitrate |
[06:26:29] | Chicago: | shadash: Why not throw the surround sound receiver out of the living room too... and get rid of the dvd players too... and just run cables |
[06:26:32] | shadash: | ineresting |
[06:26:38] | wagnerrp: | should handle lower stuff coming out of an HDPVR |
[06:26:43] | Lexridge (Lexridge!n=Lexridge@75.108.69.120) has quit ("Leaving") | |
[06:26:49] | wagnerrp: | and broadcast SD |
[06:26:54] | shadash: | that's what I want to hear :-) |
[06:27:14] | shadash: | sweet |
[06:27:19] | tjcarter: | Chicago: I got much quieter and much cooler by changing from an Antec Sonata II to a Cooler Master case.. |
[06:27:20] | rooaus (rooaus!n=cameron@ppp118-208-180-209.lns10.mel4.internode.on.net) has left #mythtv-users () | |
[06:27:23] | wagnerrp: | but broadcast HD may be iffy, and higher levels from the HDPVR and bluray is right out |
[06:27:41] | tjcarter: | Chicago: of course the CM case is a Centurion that's built like a slightly shotgunned Stacker |
[06:27:44] | tjcarter: | =D |
[06:28:17] | Chicago: | cool |
[06:28:35] | tjcarter: | That's rather the idea. |
[06:28:42] | shadash: | wagnerrp: would you recommend a mac mini for hidef frontend? |
[06:28:53] | wagnerrp: | for mpeg2, sure |
[06:28:59] | wagnerrp: | for h.264, absolutely not |
[06:29:09] | shadash: | what about with the new nvidia drivers? |
[06:29:23] | shadash: | will that make a difference |
[06:29:23] | Chicago: | I think I am going to go for 3U on a new backend. |
[06:29:26] | wagnerrp: | the new nvidia drivers are great and all... but the minimac has intel graphics |
[06:29:36] | shadash: | doh |
[06:29:43] | tjcarter: | http://www.newegg.com/Product/Product.aspx?Item=N82E16811119152 |
[06:30:09] | Chicago: | For the frontend.... honestly, all I really want to do is run HDMI into 3 highdef tvs. |
[06:30:15] | tjcarter: | Check the pics |
[06:30:22] | wagnerrp: | coolermaster makes decent stuff |
[06:30:25] | tjcarter: | I'm not kidding about the slightly shotgunned |
[06:30:28] | Chicago: | But have NVIDIA mux the video across all three screens. |
[06:30:34] | wagnerrp: | but i fail to believe that it is quieter than a sonata |
[06:30:42] | shadash: | so I'm stuck with a huge pc for my frontend |
[06:30:56] | tjcarter: | The thing looks like it's gone 100 rounds with Elmer Fudd |
[06:31:15] | wagnerrp: | shadash: check out the HTPC format cases |
[06:31:35] | shadash: | I'll look again |
[06:31:38] | wagnerrp: | size and shape of an AV receiver |
[06:31:42] | tjcarter: | I think I've gotta agree with the minimac for a FE though |
[06:32:07] | Chicago: | Why do you need a computer for a frontend? |
[06:32:19] | wagnerrp: | get a low profile cards (or onboard nvidia), use a CF card, or netboot, and a nice 3rd party heatsink |
[06:32:26] | Chicago: | The frontend only needs feeds... The video feed, remote control feed... audiofeed. |
[06:32:34] | Chicago: | No need for any equipment that makes noise. |
[06:32:35] | tjcarter: | Chicago: you need something that's got the CPU for h.264 codecs these days |
[06:33:11] | wagnerrp: | tjcarter: actually, something like the PS3 can play back anything mythtv can record (besides framegrabbers) |
[06:33:24] | tjcarter: | I wouldn't do that with an AppleTV (it can't handle the high res h.264 content, and it can't reall do the low-res stuff without Apple's OS--and MythFrontend BLOWS on OS X, I'm sorry but it's true) |
[06:33:24] | wagnerrp: | it just has no support for livetv |
[06:33:31] | shadash: | ugh nvidia should just make a barebones that is hidef capable |
[06:33:38] | Chicago: | tjcarter: You're telling me... last night I was trying to send raw uncompressed yuv4mpegpipe through ffmpeg and do a crop bottom,top,left,right and encode to H264... I was seeing framerates as low as 5. |
[06:33:43] | hadeees: | what do you think the playback limits are for a 2.16GHz mac mini? |
[06:33:50] | Chicago: | Sometimes less than two frames per second. |
[06:34:00] | tjcarter: | Chicago: On an AppleTV? |
[06:34:07] | Chicago: | hadeees: How fast is the front side bus of the mac mini? |
[06:34:09] | wagnerrp: | hadeees: should manage ~8mbit h.264, or any mpeg2 you throw it |
[06:34:18] | tjcarter: | Chicago: It's a Dothan, it can't handle it. |
[06:34:22] | wagnerrp: | (or 16-mbit if broadcast) |
[06:34:41] | Chicago: | tjcarter: No on an AMD Athlon XP-1800+ with 2G ram and fast hard disks. |
[06:34:50] | hadeees: | Chicago, 667MHz FSB |
[06:34:53] | tjcarter: | Don't get me wrong, I'd use an AppleTV if I had a need for that exact hardware spec, but MythFrontend ain't it. |
[06:35:04] | tjcarter: | oh |
[06:35:12] | tjcarter: | yeah that's not enough CPU |
[06:35:23] | wagnerrp: | Chicago: dont expect to do anything h264 fast |
[06:35:40] | ** tjcarter isn't interested in a PS3 until someone properly hands Sony their ass. ** | |
[06:35:54] | Chicago: | tjcarter: Not really... it was i/o bound on the disk. The raw yuv4mpegpipe was taking control of my i/o at 133000 kbit/sec. |
[06:36:05] | tjcarter: | PSX on hard drive was tempting, but no. |
[06:36:38] | Chicago: | Well I learned a lesson though. As long as I don't need to use the raw uncompressed video stored on disk, I can do things much closer to realtime. |
[06:37:05] | tjcarter: | I figure someone will get around to making a decent hardware-assisted emu for the PS2 sooner or later and any chubby PS2 will have the same feature. |
[06:37:15] | hadeees: | i'm thinking about buying an upgraded MacMini with a 2.16GHz chip to use as a mythtv frontend but i'm worried about higher end 1080p videos |
[06:37:25] | tjcarter: | and any pstwo someone feels like soldering the 40 wires for (lol) |
[06:37:50] | Chicago: | tjcarter: Cell phones are getting closer to being a mythfrontend every day. |
[06:37:51] | wagnerrp: | Chicago: on my 2.4GHz C2, i do DVD rips at around 12fps, HDTV encodes at 2–3fps |
[06:38:17] | Chicago: | wagnerrp: default bitrate? full frame rate? |
[06:38:19] | wagnerrp: | my system is considerably more powerful than yours, h.264 is just very intensive |
[06:38:43] | Chicago: | Yeah |
[06:38:52] | tjcarter: | Chicago: well, IMO a proper Mythfrontend on a Mac should be using QuickTime with the addition of the appropriate QT codecs for handing rtjpeg and nuv files |
[06:38:53] | wagnerrp: | dvdrips are cropped, but not rescalled, usually ~1mbit |
[06:39:17] | wagnerrp: | tv is ivtc'd, not cropped or rescalled, 5–6mbit |
[06:39:25] | Chicago: | Yesterdays Rube Goldberg was yuv4mpegpipe -> ffmpeg ffv1 lossless -> mencoder x264. |
[06:39:29] | Chicago: | Took way too long. |
[06:39:51] | tjcarter: | It'd make MythFrontend on a Mac a bit of a deviation from how things were done in Linux, but with the code refactored properly, that can be appropriate. |
[06:39:51] | Chicago: | ah |
[06:40:03] | wagnerrp: | resolution actually has little bearing on encode speed |
[06:40:10] | wagnerrp: | its all bitrate and settings |
[06:40:18] | Chicago: | In ffmpeg I pass the -ilme mpeg2video argument which is supposed to perfectly handle the interlacing from my hauppauge encoder card. |
[06:40:47] | wagnerrp: | and i would dearly hope you could manage better i/o than 133mbps |
[06:41:00] | wagnerrp: | unless youre buffering all that to disk |
[06:41:12] | Chicago: | wagnerrp: And since the encoder can be set to make progressive frames internally, the inverse tele-syncing using filmdint or pullup also look good. |
[06:41:23] | Chicago: | wagnerrp: MB |
[06:41:30] | ** tjcarter can't really take the time to relearn C++ (I last used it 12 years ago, and it's a different language today), given the "fun" I am having as a graduate student. ** | |
[06:41:36] | Chicago: | I had the vbitrate_peak_bitrate set to 27000000 |
[06:41:50] | wagnerrp: | its 'telecine', not 'tele-sync' |
[06:41:54] | wagnerrp: | just nit picking |
[06:42:03] | tjcarter: | Chicago: that'd explain a lot. |
[06:42:25] | Chicago: | tjcarter: The picture was beautiful. |
[06:42:29] | Chicago: | It was worth watching. |
[06:42:37] | Chicago: | All the v4l2-ctrl settings tuned up. |
[06:42:39] | Chicago: | mmm mmm good. |
[06:42:50] | tjcarter: | Chicago: I doubt your content has enough motion to make that setting worthwhile though |
[06:42:59] | Chicago: | I tested against ESPN. |
[06:43:00] | Chicago: | :) |
[06:43:20] | wagnerrp: | tjcarter: BRs average around that bitrate |
[06:43:48] | tjcarter: | Yeah but you can accurately record subliminal messages in half that. |
[06:44:18] | tjcarter: | especially with x264 codec |
[06:44:19] | Chicago: | When I dump that yuv4mpegpipe directly into mplayer it looks really good and I honestly haven't seen a better picture out of this encoder in 3 years. |
[06:44:41] | Chicago: | These work best for me: -c video_peak_bitrate=27000000,video_bitrate=9000000,volume=58880,audio_layer_ii_bi trate=13,audio_crc=1,spatial_filter_mode=1,temporal_filter_mode=1,median_filter_ type=3,video_gop_size=12 |
[06:45:04] | tjcarter: | madness |
[06:45:08] | tjcarter: | those bitrates are too high |
[06:45:18] | wagnerrp: | but... there are no video encoding settings in there |
[06:45:30] | Chicago: | And then on the channel changes in MythTV I use an external script todo -c brightness=128,contrast=64,saturation=64 on each channel change. |

[06:45:50] | shadash: | how long can a vga cable be before it suffers signal degradation |
[06:45:56] | Chicago: | tjcarter: Those are the bitrates to the encoder chip. That's not the size of the mpeg. |
[06:46:06] | tjcarter: | shadash: depends on the quality of the VGA cable |
[06:46:08] | wagnerrp: | shadash: that depends entirely on the cable |
[06:46:10] | Chicago: | shadash: I trust 50 ft runs on good cable. |
[06:46:19] | shadash: | hmmm |
[06:46:30] | tjcarter: | shadash: a good multi-mini-coax VGA cable can run 100ft |
[06:46:42] | wagnerrp: | my sister has some ghosting on a 15ft run of vga to her tv |
[06:46:50] | clever: | ive put a single vga extension that wasnt even 10 feet in |
[06:46:58] | tjcarter: | and that's at 1900x1200 |
[06:47:01] | wagnerrp: | i havent gotten around to getting a replacement for the single shielded cable |
[06:47:04] | clever: | it lost enough signal that the picture wouldnt line up anymore |
[06:47:24] | hadeees: | do you think a mac mini with a 2.16GHz Core Duo can play back 1080p at a bitrate of 9644 kbps? |
[06:47:27] | wagnerrp: | yeah, it cant properly sync to 1680x1050, i had to drop it to 1440x900 |
[06:47:39] | wagnerrp: | hadeees: that depends on the source |
[06:47:43] | tjcarter: | shadash: the best VGA cables have 5 mini coax lines. DDC lines don't have to be coaxes |
[06:47:49] | MarineTim (MarineTim!n=fenn@c-98-210-17-54.hsd1.ca.comcast.net) has joined #mythtv-users | |
[06:47:55] | Chicago: | That's dependent on your nvidia card. |
[06:47:57] | wagnerrp: | if the source knows what theyre doing, yes |
[06:48:02] | hadeees: | wagnerrp, how so? i'm talking about ripping blueray movies |
[06:48:07] | tjcarter: | great card and cable can do 100ft |
[06:48:15] | shadash: | mabey ill just put my frontends and backed all in the same room then just run cables in the walls |
[06:48:25] | tjcarter: | Belkin cable and the average NV card, 10 ;) |
[06:48:29] | wagnerrp: | if the source is some retard who decided that removing all slices to marginally improve compression was a good idea, the minimac will not handle it |
[06:49:00] | wagnerrp: | actually, is that core duo? or core 2 duo? |
[06:49:11] | tjcarter: | minimac is C2D |
[06:49:16] | wagnerrp: | core duo, that chip might handle 6mbps per slice |
[06:49:24] | hadeees: | wagnerrp, core 2 duo |
[06:49:26] | wagnerrp: | c2d at that speed would probably handle 8mbps |
[06:49:50] | wagnerrp: | maybe 11–12 coming out of the quicktime encoder |
[06:50:27] | wagnerrp: | note, you have two cores, so if the video has two or more slices, you double that bitrate |
[06:50:28] | tjcarter: | x264 is a little more demanding than QT, and that's what everyone seems to use, so it's what I'd go by |
[06:50:30] | hadeees: | wagnerrp, what about coreavc? if that ever gets working right |
[06:50:45] | hadeees: | wagnerrp, what is a slice? |
[06:51:01] | wagnerrp: | slices are literally segregated domains in the video |
[06:51:09] | Chicago: | I am beginning to thing x264 is too cpu intensive for a streaming protocol. The msmpeg4 vcodec is fast and plays on my phone. (the only reason I transcode is to play on my phone) |
[06:51:12] | wagnerrp: | that are encoded and decoded independently in parallel |
[06:51:38] | Penfold (Penfold!n=mikewh@nsabfw1.nsab.se) has joined #mythtv-users | |
[06:51:45] | wagnerrp: | so if a video has two slices, you can use two cores to decode it |
[06:51:52] | clever: | wagnerrp: something like encoding the left and right half of the video as 2 streams? |
[06:52:00] | wagnerrp: | clever: correct |
[06:52:08] | clever: | ahh |
[06:52:08] | tjcarter: | Chicago: x264 is CPU intensive. There are kinder H.264 codecs out there, but they're not as good size for quality. |
[06:52:25] | tjcarter: | Chicago: bigger files, but kinder CPU (or reduced quality for same size) |
[06:52:37] | clever: | wagnerrp: if you try to slice a video up like that with little cpu power, i assume youll get artifacts near the seam |
[06:52:41] | clever: | wagnerrp: does that sound right? |
[06:52:41] | wagnerrp: | tjcarter: that is completely untrue |
[06:52:52] | hadeees: | wagnerrp, so if it is a core 2 duo though shouldn't it be able to handle 2 slices? |
[06:53:05] | wagnerrp: | it should be able to handle 100 slices |
[06:53:11] | wagnerrp: | but it can only run two in parallel |
[06:53:27] | tjcarter: | wagnerrp: it is true with Apple vs. x264 at least |
[06:53:28] | wagnerrp: | tjcarter: you can disable those options that enable additional compression in x264 |
[06:53:40] | wagnerrp: | the biggest one is CABAC vs. CAVLC |
[06:53:54] | tjcarter: | oh, I was talking default settings |
[06:53:57] | wagnerrp: | quicktime only supports CAVLC, and you can configure x264 to use that as well |
[06:54:03] | tjcarter: | I don't know enough to substantially tweak stuff |
[06:54:23] | wagnerrp: | i think its just '--cabac=0' |
[06:54:33] | clever: | wagnerrp: if i was to just cut half the macroblocks out of the video, could i still decode it with only artifacts near the edge? |
[06:54:41] | wagnerrp: | plus theres some other stuff on how b-frames are handled |
[06:54:41] | clever: | at half the cpu load |
[06:54:51] | ** tjcarter would be curious if wagnerrp's suggestion fixes the problem for Chicago ** | |
[06:55:20] | wagnerrp: | clever: what are you talking about? |
[06:55:26] | hadeees: | wagnerrp, what is the different between quicktime and coreavc? if quicktime could handle 11–12 and regular is only 8mbps |
[06:55:41] | wagnerrp: | hadeees: im talking about the encoder |
[06:55:43] | clever: | wagnerrp: could you reslice a video with minimal cpu usage? |
[06:55:47] | hadeees: | wagnerrp, ah |
[06:55:53] | hadeees: | i meant decoding |
[06:55:54] | clever: | wagnerrp: (yes i know this would cause artifacts at the seam) |
[06:56:13] | hadeees: | i'm only going to use the macmini for decoding |
[06:56:34] | wagnerrp: | quicktime cannot encode using cabac, instead using the considerably less intensive cavlc for entropy compession |
[06:56:45] | tjcarter: | clever: those could be minimized I think, though it'd require the algorithm be very clever in the encoder |
[06:56:46] | wagnerrp: | clever: i dont know enough about the codec to answer your question |
[06:57:04] | wagnerrp: | but im going to say no |
[06:57:24] | wagnerrp: | theres too much data stored in the motion vectors that would have to be recomputed |
[06:57:25] | clever: | tjcarter: but at the expense of some quality, you could in theory just slice the frames into 2 or 4 sections and spread it over the cores |
[06:57:38] | tjcarter: | clever: you'd have to bias things at the seam based on knowledge of what was on the other side of it technically not part of the expected generation algorithm. |
[06:57:49] | clever: | wagnerrp: are the motion vectors relative to the source of the motion or the whole frame? |
[06:58:11] | wagnerrp: | they give motion of the macroblock |
[06:58:14] | clever: | tjcarter: but if you just ignored the problems arround the seam, and treated it like the edge of a normal frame? |
[06:58:17] | Chicago: | Hmm... I read your commend about --cabac. I haven't read about them in the man page yet... I did notice that my source material was 12bpp color and that x264 was spending time making 24bpp color. |
[06:58:31] | wagnerrp: | clever: and at the moment, im really talking out of my ass |
[06:58:36] | clever: | lol |
[06:58:40] | tjcarter: | clever: you'd get a seam for sure that way, but the encode would be faster. |
[06:58:48] | tjcarter: | clever: way less complex too |
[06:58:48] | wagnerrp: | these are just assumptions on how the internals of the codec works |
[06:59:00] | Chicago: | I didn't get any tearing. I did choose a multiple of 16 for the width and height. |
[06:59:04] | clever: | tjcarter: so that would be a start for improving software decoding |
[06:59:16] | clever: | for those who can accept an ugly seam down the middle of the frame |
[06:59:36] | Chicago: | The source material I fed to mencoder was ffv1 from ffmpeg made from a yuv4mpegpipe from mplayer. |
[06:59:52] | Chicago: | The ffv1 is ffmpeg's lossless codec. |
[06:59:59] | tjcarter: | clever: If you've got the muscle on the encoder though, you could probably lie about the stuff that lies on the seam based on what's across it so that there is no visible seam. |
[07:00:21] | tjcarter: | clever: if your method of doing it was particularly brilliant, you'd never notice a quality loss. |
[07:00:21] | wagnerrp: | ffv1 is not ffmpeg's lossless codec, its just their implementation of huffyuv |
[07:00:30] | clever: | tjcarter: i was just thinking of a way to do it in the decoder |
[07:00:37] | tjcarter: | oh |
[07:00:41] | clever: | tjcarter: treat the 1 slice as if it was 2 or 4 slices |
[07:00:41] | Chicago: | tjcarter: Yeah, but you can't lie about doing three passes... and if you're making a nice MPEG-4 v10 which will last a lifetime... why not take the time to make a slow one. |
[07:01:04] | tjcarter: | Chicago: I'm actually considering that you'd need 4 or 5 to pull it off well |
[07:01:21] | tjcarter: | or a lot of really clever specialized logic |
[07:01:28] | wagnerrp: | tjcarter: what could doing 3+ passes really get you |
[07:01:36] | Chicago: | q=0 is lossless for x264. |
[07:01:48] | tjcarter: | wagnerrp: slices without seams =D |

[07:02:13] | Chicago: | If I feed it ffv1 from a 27000000 constant bitrate yuv4mpegpipe, then the q:0 option from libx264 says I get losses from H264. |
[07:02:18] | wagnerrp: | when doing 2-pass encoding, the first pass is there to estimate how much bitrate is needed per scene |
[07:02:36] | wagnerrp: | so the second pass can properly allocate it and achieve a desired file size |
[07:02:55] | wagnerrp: | all you might get for additional passes is a marginally better quantizer map |

[07:03:54] | Chicago: | I would like a dual Intel Xeon box and a sata 300 raid array do to real transcoding all day. |
[07:04:26] | wagnerrp: | raid is completely unnecessary unless you are dealing with raw video on disk |
[07:04:52] | wagnerrp: | otherwise, neither the input, nor output, is going to be of significant bitrate to cause you troubles |
[07:04:52] | Chicago: | Or, a 4gb fiber channel rig. |
[07:05:10] | tjcarter: | stripes are nice for uncompressed video |

[07:05:41] | clever: | wagnerrp: the only time i used raw video was a hack to fix the flash player in mythweb |
[07:05:55] | tjcarter: | I usually go from high bitrate MPEG2 to moderate bitrate H.264 |
[07:05:55] | Chicago: | wagnerrp: My backend's disks are always busy. Recording from two tuner most of the time... and one or two frontends playing back other content from those same disks. At the moment I don't move files off the backend once they are transcoded. |
[07:06:04] | clever: | ffmpeg cant handle nuv, so i had mencoder convert to raw video/aud in .avi, which it |'ed to ffmpeg |
[07:06:18] | Chicago: | More spindles means more performance. |
[07:06:48] | wagnerrp: | yes, but the video bitrates are so inconsequential, the disks hardly know youre even hitting them |

[07:07:15] | wagnerrp: | the MOST you will ever see is just under 20mbit |
[07:07:24] | wagnerrp: | 2.5MB/s is nothing to a modern hard drive |
[07:07:48] | wagnerrp: | you can do 10 streams of that simultaneously before the drive might hiccup |
[07:08:09] | Chicago: | Yes, but if you run gentoo and want to compile ALL day... and have a frontend running on the same machine as the backend... you want disks. |
[07:08:11] | wagnerrp: | and if linux is properly caching writes, you can probably do double that |
[07:09:07] | wagnerrp: | you rebuild your machine after each nightly portage sync? |
[07:09:08] | Chicago: | I just refused to accept running the mysql instance on my backend or frontend machine... it make Live TV listing information unusable. |
[07:09:17] | tjcarter: | Ubuntu is an ancient African word which means "Sick of compiling Gentoo" |
[07:10:01] | Chicago: | wagnerrp: Not the mythtv box. But, when update time does come around, I don't want my recordings to suffer and I don't want the frontend to stutter. |
[07:10:22] | Chicago: | lol |
[07:10:25] | tjcarter: | Chicago: so do your compiling on another host |
[07:10:35] | tjcarter: | boxes are cheap, and so is distributed compilation |
[07:10:36] | wagnerrp: | Chicago: if you struggle to compile because of random disk access, you could just as easily take that $50 you would have otherwise spent on another hard drive, buy an extra 4GB of memory, and compile in a RAM disk |
[07:10:36] | Chicago: | I almost spit hot coffee out of my mouth and onto my monitor. |

[07:11:53] | Chicago: | tjcarter: The MythTV machine is created for itself with -march=athlonXP. It compiles everything it runs. The other machines do the same thing. I have a P4, and a P3 and athlon k7... each one has the specific march. |
[07:12:01] | tjcarter: | Chicago: see, I have an iMac, so there's a nice coffee-repellant plexiglas cover over my screen. |
[07:12:05] | Chicago: | So that if I get another of the same type, then I can reuse the binaries I made previously. |
[07:12:17] | tjcarter: | Also a silicone condom over my keyboard |
[07:12:18] | wagnerrp: | Chicago: did you install using a stage3? |
[07:12:46] | Chicago: | wagnerrp: There is 2G of memory on the machine. The OS partition is 130 and the mythtv box doesn't even touch those discs. |
[07:12:47] | tjcarter: | (THAT BTW is the best $25 I ever spent) |
[07:13:19] | tjcarter: | Chicago: distcc can compile for any arch you want |
[07:13:21] | Chicago: | MythTV uses two 160G ata100 seagates with 16MB buffers... running lvm |
[07:13:35] | Chicago: | tjcarter: Only if everyone playing distcc has the same glib and gcc and kernel. |
[07:13:40] | tjcarter: | Chicago: put your hardware to work using up unused cycles on all of those machines |
[07:14:03] | wagnerrp: | Chicago: not true, you build an abstraction layer for distcc to compile against |
[07:14:08] | wagnerrp: | theres howtos for that on the gentoo wiki |
[07:14:10] | tjcarter: | Chicago: I do distcc for my Linux box on my Mac |
[07:14:19] | Chicago: | The athlonk7 is hardened and uses gcc-3.6 and its the only machine with gcc3... so it can't receive help or give up. |
[07:14:23] | tjcarter: | Chicago: there are ways, they're just not how Gentoo sets it up for you. |
[07:14:31] | Chicago: | But yes, the other three boxes do distcc for me sometimes. |
[07:14:33] | wagnerrp: | theres command line tools almost set it up for you |
[07:14:57] | tjcarter: | wagnerrp: he's a Gentoo user, so therefore hopeless |
[07:15:18] | Chicago: | I setup an ssh connection for distcc to use after learning about it from gentoo-wiki. That was cool. |
[07:15:33] | tjcarter: | wagnerrp: brute force "Ugg smash!" is pretty much the standard solution on Gentoo ;) |

[07:16:04] | Chicago: | wagnerrp: So when my new 2.6.26 kernel finishes building and I compile the ivtv driver again, I will reboot the MythTV box and do this ffmpeg transcoding again. |
[07:16:04] | tjcarter: | No two machines are identical, so therefore everything must be tweaked to squeeze a tenth of a milisecond per hour out of it. |
[07:16:24] | tjcarter: | By giving up 40% of CPU time to compiling shit over and over again ;) |
[07:16:32] | wagnerrp: | tjcarter: im a gentoo user, but sometimes im ashamed of my community |
[07:16:45] | Chicago: | The failure I had using 2.6.25 w/ ivtv v1.2.0 is that mencoder refused to accept /dev/v4/video{1,2} as an input for me to pipe into stream to send to ffmpeg. |
[07:17:04] | tjcarter: | wagnerrp: my condolances. I was a Gentoo user, but I got better. |
[07:17:05] | wagnerrp: | for instance, a couple months ago when there was a fork because some people thought it was against the ideals of gentoo to allow a pre-built stage3 install |
[07:17:37] | tjcarter: | I got over it about the time when the Genroo people kinda had a falling out with drobbins |
[07:18:35] | ** tjcarter wonders what those guys are doing these days, aside from getting ready to have the Ducks kick their ass again ;) (You can tell which college I went to right?) ** | |
[07:18:49] | Chicago: | I need a gentoo release schedule though. |
[07:18:52] | wagnerrp: | the only reason i use gentoo is because the package system is similar to freebsd |
[07:18:59] | wagnerrp: | it just seems more... right... to me |
[07:19:16] | wagnerrp: | plus the whole relatively simple use of config files |
[07:19:32] | Chicago: | Honestly I think I should setup one portage rsync server in the house... and only sync it once per week... or once every month.... or once every 3 months. |
[07:19:32] | wagnerrp: | rather than funky abstracted files intended only for use by the distro's config guis |
[07:19:45] | tjcarter: | wagnerrp: my only complaint with dpkg-based systems (and rpm-based for that matter) is that the library bloat is a bit ridiculous |

[07:20:09] | Chicago: | But that's too small now. |
[07:20:27] | Chicago: | for /usr I mean |
[07:20:33] | wagnerrp: | tjcarter: ive developed some small hatred towards rpms after having to deal with them on suse systems at work |
[07:20:37] | tjcarter: | These days though, I've taken to doing stuff like 3 partition Linux systems |
[07:20:41] | wagnerrp: | i have no love for suse |
[07:21:09] | tjcarter: | 3 partitions, small systems, low overhead |
[07:21:19] | MarineTim: | is anyone here using rpmfusion's mythtv with a firewire connection? |
[07:21:31] | wagnerrp: | rpmfusion? |

[07:22:51] | Chicago: | So the reasons I am using Gentoo start with the mythtv wiki. They explained installing mythtv onto gentoo in only two words. "emerge mythtv".... |
[07:22:54] | Chicago: | I was in love. |
[07:23:41] | tjcarter: | it's not that simple. |
[07:23:52] | tjcarter: | It's almost that simple on modern Ubuntu systems though |
[07:23:53] | wagnerrp: | Chicago: you should have been around several years ago when the ivtv drivers were still very much development grade |
[07:24:06] | Chicago: | I was |
[07:24:15] | Chicago: | I didn't say it actually worked. |
[07:24:24] | tjcarter: | that is, assuming they have stopped changing how MySQL doesn't talk to networks every version or so. |

[07:26:42] | wagnerrp: | are you pulling video directly off the framegrabber, rather than using the mpeg interface? |
[07:26:55] | Chicago: | I don't remember where the settings was though... it was either a v4l2 control or part of ffmpeg knowing its attached to encoder hardware. |
[07:27:05] | tjcarter: | I have never been able to pull video off with the grabber |
[07:27:15] | tjcarter: | well, let me rephrase |
[07:27:22] | tjcarter: | I don't have any software that seems to want to do that. |
[07:27:23] | Chicago: | The -ilme mpeg2video setting in mencoder or ffmpeg is aware of the encoder's frames from the pvr500 |
[07:27:30] | tjcarter: | I thought tvtime did, but I couldn't get it to |
[07:27:46] | Chicago: | mplayer is supposed to by using the pvr:// and tv:// controls. |

[07:30:45] | tjcarter: | several |
[07:31:33] | tjcarter: | 4, it's a bit dated |
[07:31:52] | Chicago: | If you aren't using the onboard usb / audio/firewire/ try disabling them in the bios or by the jumper... and then test again using the 4th or 5th pci slot. |
[07:32:03] | tjcarter: | I am using them |
[07:32:07] | Chicago: | Usually the 4th or 5th pci slot share irqs with the other onboard devices. |
[07:32:13] | tjcarter: | I could disable the audio though |
[07:32:17] | Chicago: | pci slot 2 and 3 don't usually suffer from those problems. |
[07:32:28] | Chicago: | pci slot 1 usually sucks because it shares with the AGP. |
[07:32:32] | Chicago: | if you have legacy hardware. |
[07:32:44] | tjcarter: | It's not quite that legacy =D |
[07:33:01] | tjcarter: | it's at least PCI-E |
[07:34:06] | tjcarter: | the problem was that KM's driver loading would often catch the first PVR-150 of the 500, then the grabber, then the second -150 |
[07:34:12] | tjcarter: | But not always. |
[07:34:20] | tjcarter: | Sometimes the two -150's, then the grabber |
[07:34:23] | Chicago: | That's a ivtv driver problem. |
[07:34:38] | Chicago: | In your /etc/modules.d/ivtv tell it to make the first encoder #1 rather than 0. |
[07:34:43] | Chicago: | Then you wont have problems with that. |
[07:34:59] | wagnerrp: | he probably doesnt have one of those files |

[07:35:42] | tjcarter: | mixing grabbers and MPEG PVRs on the same box |
[07:35:50] | Chicago: | And so I either get conflicts or I number the ivtv driver starting at 1. |
[07:36:12] | tjcarter: | that could work |
[07:36:16] | tjcarter: | make the grabber always be 0 |
[07:36:19] | justinh: | udev rules :) |
[07:36:46] | justinh: | tjcarter: yeah 4 pci slots does date a machine somewhat – ie if it has more than 3 you KNOW it's old! ;-) |
[07:37:14] | Chicago: | justinh: At least Intel still makes a server board with at least two conventional pci slots. |
[07:37:35] | MarineTim: | pfft, I use ISA and dip switches. :P |
[07:37:41] | Chicago: | If it has more than three, you know somebody bought it at a bigbox store. |
[07:37:57] | Chicago: | Retail motherboards usually don't suffer from this. |
[07:38:08] | tjcarter: | ivtv_first_minor could be just the trick |
[07:38:14] | Chicago: | Go fix it. |
[07:38:15] | Chicago: | :) |
[07:38:17] | Chicago: | It works for me. |
[07:38:20] | justinh: | pfft. it's very hard to find motherboards with more than 3 pci slots these days |
[07:38:37] | Chicago: | justinh: Only because they are discontinued. |
[07:38:37] | tjcarter: | Do I understand ivtv_yuv_mode correctly to be that the driver can do deinterlacing? |

[07:39:53] | justinh: | though it IS fair to say that very few users need that many pci slots, what with everything included on boards these days |
[07:40:01] | justinh: | Chicago: DUH! |

[07:40:33] | Chicago: | The server board I was looking at came with one 8x pci-e one 1x pci-e and two conventional pci. |
[07:40:34] | justinh: | if you want more than two tuners you need > 2 PCI slots generally |
[07:40:43] | wagnerrp: | tjcarter: you may want to rethink that |

[07:48:03] | tjcarter: | Actually, I explored that with a couple of people and we found out that card makers tend to silently change hardware without changing model numbers |
[07:48:12] | tjcarter: | That really fucks with canned configs. |
[07:48:15] | justinh: | tjcarter: yup |
[07:48:37] | justinh: | new chipsets.. sometimes all kinds of weirdness |
[07:48:38] | ** tjcarter doesn't have time for actual development unfortunately ** | |
[07:49:02] | tjcarter: | My university has decided that a blind person should not be allowed to pursue my professional career choice. |
[07:49:02] | wagnerrp: | everyone has the time for actual development, they just choose to spend their free time elsewhere |
[07:49:06] | justinh: | for what it is, considering it's only people doing stuff in their spare time – mythtv is about as good as you're gonna get |
[07:49:23] | Chicago: | justinh: Not exactly. |
[07:49:31] | justinh: | Chicago: yes, exactly |
[07:49:31] | Chicago: | That depends if you want to stream. |
[07:49:37] | tjcarter: | Needless to say, that's generating more work for me than full-time graduate-level coursework. |
[07:49:45] | justinh: | muh muh muh. 2.0 2.0. BOLLOCKS |
[07:49:57] | Chicago: | How can I tell mythtv "start making a realtime stream and send it to darwin when you play live tv". |
[07:50:06] | tjcarter: | wagnerrp: I have free time? |
[07:50:06] | justinh: | Chicago: WHO CARES? :) |
[07:50:22] | tjcarter: | wagnerrp: I am taking 9 credits as a graduate student this term, 13 next. |
[07:50:22] | justinh: | fecking whiny users. same old same old |
[07:50:23] | Chicago: | MythTV does... |
[07:50:35] | Chicago: | Because MythTV locks onto /dev/v4l/videoX |
[07:50:40] | wagnerrp: | tjcarter: ah yes... luckily im done with coursework |
[07:50:50] | wagnerrp: | now i can devote myself to procrastinating on my thesis |
[07:50:58] | Chicago: | If I want to operate myth and dump a copy of the stream transcoding it for streaming through darwin, then that would rock. |
[07:51:17] | justinh: | Chicago: you could adapt myth to only use cards on demand quite easily, but that still doesn't solve the problem of what happens when myth wants the card at the same time as something else |
[07:51:31] | wagnerrp: | streaming it through darwin? isnt that just an operating system? |
[07:51:32] | tjcarter: | wagnerrp: I save every email from school.. |
[07:51:47] | tjcarter: | wagnerrp: in my entire last year, I had 200 emails to and from faculty and staff. |
[07:51:53] | justinh: | 1174874112 100% 3.80MB/s 0:04:55 (xfer#227109, to-check=5863/280671 — arghhh I thought it'd be done by now |
[07:51:59] | Chicago: | justinh: Right... I basicly want to pipe a copy of the MPEG-PS |
[07:51:59] | MaverickTech (MaverickTech!n=Maverick@ip80-101-226-10.hotspotsvankpn.com) has quit (Read error: 110 (Connection timed out)) | |
[07:52:06] | tjcarter: | wagnerrp: In the past 10 weeks, I have had 500. |
[07:52:13] | Chicago: | justinh: So that MythTV thinks it is watching LiveTV all the time. |
[07:52:14] | justinh: | Chicago: sounds like a job for a virtual device |
[07:52:26] | tjcarter: | wagnerrp: Most of them I send requiring approval from my lawyer. |
[07:52:33] | justinh: | Chicago: and you'll get no sympathy from me for your edge case |
[07:52:45] | justinh: | livetv is way too 20th century |
[07:52:55] | wagnerrp: | a lawyer? as a graduate student? youre not supposed to have any rights... |
[07:53:01] | Chicago: | Well, does MythTV support dumping a copy of the MPEG-PS to a named pipe? |
[07:53:06] | justinh: | Chicago: NO |
[07:53:51] | wagnerrp: | justinh: actually, it does, if you consider the file system a 'named pipe' |
[07:54:03] | justinh: | hrm |
[07:54:34] | justinh: | FWIW, just whack another tuner in the box. the few dollars it'd cost is way less than the time you'll spend dicking around |
[07:55:14] | Chicago: | I like dicking around. |
[07:55:19] | wagnerrp: | add some quick code to provide remote channel changing on VLC, and be done with it |
[07:55:35] | justinh: | wagnerrp: exactly :) |
[07:55:41] | justinh: | it |
[07:55:47] | tjcarter: | wagnerrp: actually, I have rights of due process under civil rights law, and under the Americans with Disabilities Act, and Section 504 of the Rehabilitation Act of 1973, as ammended. |
[07:55:47] | Dibblah: | Personally, I do see some limited value in being able to notify a different frontend of playback position, though. |
[07:55:48] | justinh: | it'd be the lesser of two evils |
[07:55:51] | Chicago: | Well, if the mplayer channel changing worked on my 2.6.25 I'd be using it by now... but the v4l2 stuff seemed somewhat not working on my ivtv driver. |
[07:56:01] | Dibblah: | ... For the multiroom scenario, for example. |
[07:56:39] | justinh: | Dibblah: bookmarks already exist. wouldn't take too much effort to add a 'current position' marker too |
[07:57:00] | justinh: | it'd even be keyframe accurate! |
[07:57:07] | wagnerrp: | tjcarter: actually, i was speaking more of the adviser wanting you to teach his classes and do his laundry type of rights |
[07:57:38] | Dibblah: | What has that got to do wiht Myth? |
[07:57:45] | justinh: | Dibblah: though there'd be a teensy bit extra database overhead.. but nothing compared to actual recording :) |
[07:57:50] | Dibblah: | ... Really, who cares? |
[07:58:14] | Dibblah: | justinh: Not a good use of a database ;) |
[07:58:28] | Dibblah: | Mainly due to the uncertain RTT... |
[07:58:35] | justinh: | Dibblah: I've seen a media player which doesn |
[07:58:45] | justinh: | doesn't use a seektable.. and it's not very good at seeking AT ALL |
[07:58:50] | wagnerrp: | youre saying you want to synchronize playback on multiple machines? |
[07:58:56] | justinh: | certainly not accurately |
[07:58:57] | Chicago: | wagnerrp: Considering the filesystem a named pipe, can I capture the output from /dev/v4l/videoX using two separate applications? |
[07:59:00] | tjcarter: | wagnerrp: oh, this is more that some profs think a blind person cannot be allowed to earn the license that goes with this program, and trying to ensure that I fail by any means necessary.. |
[07:59:11] | tjcarter: | wagnerrp: things like blind teacher + students speaking sign language |
[07:59:29] | wagnerrp: | Chicago: perhaps, i dont know |
[07:59:41] | wagnerrp: | i was speaking more of the recording that mythtv makes, directly to a file |
[07:59:58] | Dibblah: | "considering the filesystem a named pipe"... Ohkay. |
[08:00:10] | Chicago: | The disk bandwidth here would support MythTV writing to it's /media directory and the redirected copy piped into ffmpeg -> ffserver -> dss. |
[08:00:12] | Dibblah: | A named pipe is just a filehandle. |
[08:00:13] | justinh: | Chicago: what you might be able to do is stop using the tuner in myth altogether! Then stream it as IPTV using VLC or whatever & get myth to record that – and work out the channel changing stuff.. then more than one app could use it. sounds more or less ready-made |
[08:00:40] | wagnerrp: | im betting mythtv locks the mpeg stream when recording, and even if it doesnt, trying to change the channels on tuners it wants to use is going to make it very unhappy |
[08:00:49] | Chicago: | justinh: Very nice |
[08:00:56] | Chicago: | I hadn't thought of that! |
[08:01:03] | justinh: | Chicago: probably the most viable solution you're gonna get |
[08:01:07] | wagnerrp: | i mentioned that 5 minutes ago |
[08:01:22] | justinh: | wagnerrp: reason has to be hammered into some people :P |
[08:01:27] | Chicago: | Let me understand again... |
[08:01:39] | bomama (bomama!i=4c672c76@gateway/web/ajax/mibbit.com/x-80309a83c6cb97c9) has quit (Remote closed the connection) | |

[08:01:46] | wagnerrp: | tuner --> vlc --> internet and freedom! |
[08:01:57] | Chicago: | YaY \o/ |
[08:02:18] | wagnerrp: | youll have to hash out some way to change the channels |
[08:02:20] | justinh: | I want to play with IPTV recording, just for fun |
[08:02:26] | Chicago: | In case you still use Gentoo... here are the 2.6.26 ebuilds for IVTV from SVN. http://bugs.gentoo.org/show_bug.cgi?id=234756 |
[08:02:32] | justinh: | v4l2ctl ftw :) |
[08:02:44] | Chicago: | v4l2-ctl rocks my pvr500 |
[08:02:51] | wagnerrp: | probably some php script on a website tied to ptune, or v4l2ctl, never used that one |
[08:03:00] | tjcarter: | wagnerrp: followed of course by threats of disciplinary action following blind teacher + sign language students not working out perfectly within a week's time. |
[08:04:07] | tjcarter: | wagnerrp: and it's become this grand conspiracy where everyone lies to cover for everyone else pulling this shit and their own asses for lying to cover everyone else's for pulling this shit. |
[08:04:19] | tjcarter: | office politics run amok |
[08:04:23] | wagnerrp: | to be honest, i cant recall ever taking a class with either a blind or deaf student |
[08:04:39] | tjcarter: | wagnerrp: most people forget I'm blind, actually |
[08:04:57] | wagnerrp: | i have to believe the occurrence of you coming across a deaf student will be quite rare, and you can just shift off to another teacher |
[08:05:24] | tjcarter: | I don't have most of the telltale "blind behaviors" and I get along so well that people just forget, even when I've got a white cane in my hands. It's astonishing. |
[08:05:48] | tjcarter: | wagnerrp: I'd just learn sign language. |
[08:06:02] | Chicago: | tjcarter: I wish I would have learned sign language years ago. |
[08:06:05] | tjcarter: | wagnerrp: but you wouldn't put me in a room FULL of them as the teacher until I had. |
[08:06:09] | wagnerrp: | tjcarter: the harder thing would be them learning to speak |
[08:06:18] | clever: | one of the students back in my grade 5 or 6 class had trouble speaking |
[08:06:29] | tjcarter: | and as it happens, they weren't deaf. Autism spectrum stuff. |
[08:06:33] | clever: | so she usualy spoke sign language to an assistant that was allways with her |
[08:06:45] | ** tjcarter is convinced there's not one "spectrum" for autism, but whatever. ** | |
[08:07:10] | Chicago: | My colleague claims autism is evolution. |
[08:07:12] | ** justinh copies his frontend's nfsroot to what will be the new backend HDD ** | |
[08:07:20] | Chicago: | or something to that effect. |
[08:07:22] | tjcarter: | two conditions with the opposite symptoms and some common behaviors associated with both... |
[08:07:33] | wagnerrp: | your colleague is retarded |
[08:07:37] | Chicago: | lol |
[08:07:43] | tjcarter: | that's not one problem, it's two, especially when you can name things that are not autism that have the same behaviors. |
[08:07:48] | wagnerrp: | autism is a random mutation, nothing more |
[08:07:48] | Chicago: | He did have a smile on his face when he told me. |
[08:08:01] | wagnerrp: | some recurring genetic trait |
[08:08:02] | tjcarter: | wagnerrp: we don't know that. |
[08:08:09] | tjcarter: | wagnerrp: there's no genetic trait identified |
[08:08:39] | tjcarter: | Nor have environmental toxins or anything else been positively linked with it. |
[08:08:40] | wagnerrp: | either way, the issue is that it causes a scenario where one cannot properly interact with the real world |
[08:08:51] | justinh: | Chicago: there was some damn idiot who got into a shedload of bother for suggesting that 'different' people are being punished for being bad in a previous life. dot a wucking fick! |
[08:08:51] | wagnerrp: | significantly reducing the possibility of procreation |
[08:09:03] | tjcarter: | Lots of people with Asperger Syndrome DO in fact interact with the world. |
[08:09:11] | tjcarter: | The world thinks they're a little strange, but they do. |
[08:09:22] | wagnerrp: | some do, some dont |
[08:09:24] | Chicago: | justinh: That is horrible |
[08:09:48] | tjcarter: | But Asperger Syndrome is the exact opposite symptoms of Kanner Syndrome (classic Autism) |
[08:10:00] | justinh: | and you can't go talking about mental conditions on IRC. Jees. Personality disorder central |
[08:10:06] | Chicago: | So did they say on TV that 1 in 300 kids today is born with "Autism"? |
[08:10:26] | Chicago: | lol |
[08:10:32] | tjcarter: | and Kanner Syndrome doesn't seem to lead to outcomes that allow for normal interaction--unless it turns out the person actually had Asperger Syndrome. |
[08:10:39] | tjcarter: | Chicago: they say 1 in 6, and it's crap |
[08:10:47] | wagnerrp: | they also give ritalin out at alarmingly high rates |
[08:10:47] | tjcarter: | I might buy 1 in 300 |
[08:11:21] | tjcarter: | That's because creativity and boredom are classified as ADHD and medicated to oblivion these days. |
[08:11:23] | justinh: | wagnerrp: doctors give out pills at alarmingly high rates proportionate to the kickbacks they get from drug companies :) |
[08:11:28] | tjcarter: | Might as well start passing out Soma. |
[08:12:12] | justinh: | Soma == TV, 'celebrity' culture et al :) |
[08:12:19] | wagnerrp: | justinh: it may also be proportionate to their desire to just get the parents to shaddup and go away |
[08:12:25] | tjcarter: | I'm glad to be a Beta. I wouldn't want the responsibilities of being an Alpha. And I'm fortunate not to be a Gamma... |
[08:12:26] | justinh: | true |
[08:12:48] | wagnerrp: | 'figure out whats wrong with my kid. why are they out of control? it cant be my parenting skills' |
[08:12:55] | wagnerrp: | 'sure, fine. heres some ritalin' |
[08:12:59] | tjcarter: | wagnerrp: or my teaching skills |
[08:13:16] | justinh: | because nobody would ever listen to somebody telling them they're a crap parent. oh no |
[08:13:28] | justinh: | besides, they might sue! |
[08:13:40] | tjcarter: | wagnerrp: the fact that you use the teevee as a babysitter and I expect your kid to divine mathematics out of colored blocks can't POSSIBLY have anything to do with it! |
[08:13:40] | Chicago: | Its eugenics |

[08:14:35] | justinh: | see – you know how much I've been yelled at in here for having the cheek to suggest that the ultimate parental control system already exists, therefore mythtv doesn't need one? oooo.. quite a lot |
[08:15:15] | justinh: | although I think parental controls are important.. to keep parents out :P |
[08:15:39] | Chicago: | justinh: I agree with you there |
[08:15:50] | Chicago: | In regard to mythtv isn't your parental control system. |
[08:16:07] | justinh: | well, there are things I still wouldn't want my parents to find out ;-) |
[08:16:11] | wagnerrp: | i dont know about anyone else, but im fairly certain i would have rebelled if my parents put one of those gps logging systems in my car |

[08:17:37] | justinh: | I'm not a parent, but facking heck... the lengths people were going to.. and the knee-jerk reactions to every little thing were scary |
[08:17:42] | wagnerrp: | err... college |
[08:18:14] | justinh: | these kids were looking at everybody in the street like they weren't just a _potential_ rapist/kidnapper/murderer.. they were acting as if everyone IS a threat |
[08:19:14] | justinh: | taking a kid to school, driving em right up to the gate.. checking out everybody on the pavement, not unlocking the car doors til the very lasty minute.. jees I'd hate to live in such fear |

[08:20:01] | justinh: | Chicago: and then what? have kids who have no clue how to interact with society?! |
[08:20:07] | Chicago: | What? |

[08:21:24] | Chicago: | xris: Sounds like a good deal. There was a promo code passed in this channel earlier. |
[08:21:24] | justinh: | heh |
[08:21:48] | justinh: | oh hey yeah they're doing dvb-t versions now aren't they.. soon to be sold here in UK land |
[08:21:51] | xris: | Chicago: yeah. needs a promo code from the mailing list. |
[08:21:59] | xris: | justinh: yeah, been in the works for awhile. |
[08:22:12] | xris: | Chicago: but their shopping cart servers went down at midnight. heh. |
[08:22:32] | Chicago: | Tell me about this hdhomerun. I know there is software support for it in myth, but don't know a think about the hardware/capabilities. |
[08:22:46] | wagnerrp: | Chicago: its a dual ATSC/QAM tuner |
[08:22:51] | xris: | it's a dual HD tuner device. connects to myth over ethernet. |
[08:22:56] | wagnerrp: | two inputs, two capture devices, pumped over 10/100 |
[08:23:01] | xris: | works great for broadcast/clearqam channels |
[08:23:11] | wagnerrp: | is there multirec support yet? |
[08:23:24] | xris: | myth supports it natively (silicon dust is very friendly to mythtv and open source) |
[08:23:37] | justinh: | Chicago: those people were keeping their kids indoors virtually their whole lives. Virtually the only other people they got to interact with in real life were their parents. Very, very sad. Hate to think how unbalanced those kids'll grow up. Anyway.. enough OT yabber jabber |

[08:24:46] | justinh: | I sometimes miss having to build my own kernel.. only cos I might one day find I need to & I won't remember how |
[08:24:59] | Chicago: | I was wondering why myth didn't like letting me say the pvr500 is an analog video device. v21 of Myth wants the audio channel for analog video to be /dev/dsp, but it doesn't take it raw from /dev/v4l/video25 |

[08:25:46] | Chicago: | Okay cool, I have TV. |
[08:25:48] | justinh: | Chicago: it gets the audio embedded in the video stream so whatever it says about audio in mythtv-setup with that device is irrelevant |

[08:26:33] | Chicago: | xris: It depends. There are dev nodes for raw audio and raw video. |
[08:26:40] | wagnerrp: | justinh: the PVRs also allow capture of the direct audio and video streams, framegrabber-style |
[08:26:48] | justinh: | ugh! |

[08:27:22] | justinh: | I mean.. why the heck would they? |
[08:27:33] | Chicago: | Well Its just one way to demux the output of the pvr500 for processing. |
[08:27:35] | wagnerrp: | i believe tvtime uses them by default |
[08:27:45] | xris: | Chicago: yeah, but why would you want myth to do software encoding? the mpeg2 from the pvr-500 is way better |
[08:27:48] | ** justinh bangs his head on the desk ** | |

[08:28:53] | Chicago: | For live tv playback only. |
[08:29:01] | Chicago: | Best bitrate, best picture. |
[08:29:14] | clever: | why not just use the frame grabber mode like it was meant to be used then? |
[08:29:20] | clever: | tvtime! |
[08:29:34] | Chicago: | I thought VLC was the way to go. |
[08:29:40] | clever: | it feeds the raw frames directly into the video memory |
[08:29:46] | Chicago: | Yes |
[08:29:46] | justinh: | thinking gets Betas into trouble |
[08:29:47] | xris: | Chicago: mythtv doesn't do that |
[08:29:47] | clever: | no cpu usage needed |
[08:29:48] | wagnerrp: | VLC is what you use if you want to stream something elsewhere |

[08:35:45] | wagnerrp: | does the hdhomerun need any system drivers? or is it handled entirely from within myth? |
[08:37:24] | xris: | wagnerrp: entirely within myth. it's a upnp device. |
[08:37:28] | Chicago: | wagnerrp: I see the ./configure for hdhomerun and there is a use flag for it... the myth package shows it as an input. |
[08:37:31] | xris: | works with myth, windows, osx.. |
[08:37:58] | xris: | wagnerrp: mythtv-setup just sees it on the network when you pick it as a recording option. |
[08:38:01] | wagnerrp: | so it should run just fine on a freebsd backend |
[08:38:11] | xris: | wagnerrp: theoretically, yes. |
[08:38:22] | wagnerrp: | aside from other bugs that may arise from the port |
[08:38:29] | xris: | only downfall is that it's upnp so it needs to be on the same network zone (broadcast packets get blocked by firewalls, etc) |
[08:38:38] | wagnerrp: | not a problem |
[08:39:08] | wagnerrp: | the bigger problem is that i may have to fix a different UPNP bug if i want to shift my primary backend to my freebsd file server |
[08:39:28] | wagnerrp: | last time i tried that, i got errors galore when trying to stream mp4 |
[08:40:08] | Chicago: | The consequences of enabling upnp on your router is that any windows machine can open/close ports as it pleases. |
[08:40:24] | wagnerrp: | yeah... so i just dont enable upnp on my router |
[08:40:26] | wagnerrp: | easy solution |
[08:40:31] | clever: | Chicago: and in theory, a virus could open the firewall up to let others in |
[08:40:57] | clever: | Chicago: azureus also has the ability to use a routers upnp to forward the torrent ports automaticaly(not allways windows) |
[08:41:14] | wagnerrp: | easier solution, my router does not support upnp (as i have never programmed it in) |
[08:41:34] | Chicago: | very nice |
[08:41:45] | clever: | wagnerrp: same 'problem' with mine, its purely bash scripts |

[08:57:50] | wagnerrp: | its also designed for ease and cooling, not sound |
[08:58:34] | wagnerrp: | thats my only complaint about the 180, too difficult to build in |
[08:58:57] | directhex: | sure, but try comparing internal shots of the p180 and the v1100 :p |
[09:02:38] | wagnerrp: | its also twice the price |

[13:21:01] | gbee: | could be that emusic is now embedding in the id3 tags I guess |
[13:36:59] | justinh: | more than likely :) |
[13:37:14] | justinh: | cos I very much doubt mythmusic is grabbing any album art |
[13:37:57] | clever: | ive for 100's of albumart_randomcrap.jpg files, does mythmusic know which one to use? |
[13:38:04] | clever: | (i moved them all to 1 folder) |
[13:38:17] | justinh: | it'll use them in order of filename AFAIK |

[13:38:33] | justinh: | that's what I found last time I noticed it |
[13:38:57] | clever: | but my albumart files are in a totaly diff dir from the music they belong to |

[13:39:23] | justinh: | what kind of smack are you on, clever? |
[13:39:41] | justinh: | the album art has to be in the same directory as the music file(s) |
[13:39:48] | justinh: | if not embedded in the tag :) |
[13:39:51] | clever: | i moved every jpg to a single folder to clean the horid mess up |

[13:40:05] | clever: | now they arent paired up with the songs and i dont know how to fix it:P |

[13:48:11] | clever: | all i managed to do was bring down 6 systems with 1 bad harddrive |
[13:48:37] | gbee: | can't see a configuration issue that would cause the crappy performance, so that leaves the driver (tried 3 versions) or the GPU itself is just rubbish |
[13:48:41] | dustybin: | clever: would you mind drawing a diagram of your setup |
[13:48:59] | clever: | dustybin: the nfs server had a hdd go tits up durring a long read |
[13:49:08] | clever: | dustybin: which screwed up the nfs client(cant kill -9 the prog) |
[13:49:22] | clever: | the nfs client was also the server for the nfsroot |
[13:49:46] | clever: | so i had to shut down every nfsrooted system(4), and the server(1), and the windows box was in horid shape so i did it at the same time |
[13:49:49] | clever: | totaling 6 systems |
[13:51:08] | gbee: | having spent extra on a 8200 motherboard with hdmi/dvi/vga I'm facing having to buy card to go in there, completely defeating the point |

[13:51:27] | dustybin: | gbee: sell it on ebay |
[13:51:35] | gbee: | just can't emphasise how poor the 2D performance is, nevermind the opengl perf |

[13:58:55] | gbee: | for now I'll put up with it and think about a cheap 8xxx/9xxx series in January |
[13:59:13] | justinh: | how much does a basic fanless VDPAU thingy cost anyway? |
[13:59:19] | gbee: | or an ATi IGP |
[13:59:45] | gbee: | no clue, can't be that much |
[14:01:15] | justinh: | GF8400 for £20 |
[14:01:25] | justinh: | ! |
[14:01:38] | justinh: | not fanless though |
[14:01:43] | gbee: | the VDPAU capabilities of this chipset are it's only saving grace right now, but even the older generation Radeon x1250 IGP in my production machine performs better in menus/screens |
[14:02:28] | gbee: | worth considering if the fan is speed controlled maybe, this board will SLi the IGP with the discrete GPU |

[14:02:50] | justinh: | ugh turbocack |
[14:03:00] | justinh: | but it has 256MB onboard |

[14:14:14] | dustybin: | Video Decode and Presentation API for Unix |
[14:15:16] | dustybin: | VDPAU is the Linux equivalent of the Microsoft's DirectX Video Acceleration (DxVA) API for Windows <-- wow i didnt know that |
[14:17:15] | directhex: | that's a little disingenuous. it's ONE equivalent |
[14:17:19] | directhex: | there's no common standard |
[14:17:26] | dustybin: | am i right in thinking that you could use a really low spec CPU, like a PIII, as long as the box has a GF 8 series gfx onboard, one can still watch HD perfectly on it? |
[14:17:40] | directhex: | vdpau for nvidia, xvba for ati, vaapi for intel |
[14:17:41] | clever: | what is a good program to benchmark how a CPU can handle diff types of computation? |
[14:17:46] | clever: | under linux |

[14:18:46] | clever: | thanks:) |
[14:19:15] | clever: | was looking at the benchmarks from boinc and the ratio of floating point mips and int mips didnt match up between systems |
[14:19:26] | clever: | it wasnt a general across the board gain in speed |
[14:19:41] | clever: | 28 10:12:50 <@clever> 1.6ghz P4, 556 floating mips, 1310 int mips |
[14:19:41] | clever: | 28 10:15:04 <@clever> 1.6ghz laptop, 797 floating mips, 2847 int mips |
[14:20:05] | clever: | the laptop is the same freq, but performs nearly twice as fast for integer operations |
[14:21:22] | clever: | and only slightly better for floating point |
[14:22:03] | directhex: | why does that not match up? |
[14:22:15] | clever: | different cpu designs id guess |
[14:22:29] | directhex: | right |
[14:22:32] | clever: | it would also explain why the 1.6ghz P4 cant handle 264, while the laptop can handle most 264 |

[14:22:58] | directhex: | pentium-m is a much newer, much better design |
[14:23:11] | clever: | thats clear just from the performance and numbers |
[14:23:19] | directhex: | pentium-m is basically core solo |
[14:23:23] | directhex: | give or take |
[14:23:55] | clever: | i was just thinking, if you apply some basic division to the freq and mips |
[14:24:02] | clever: | you could get the avg cpu cycles/intruction |
[14:24:12] | directhex: | not quite |
[14:24:22] | clever: | depends on how the program counts mips |
[14:24:41] | directhex: | the number you're thinking of is FLOPs/cycle, or floating point operations per cycle |
[14:24:56] | directhex: | but cycles != instructions. that introduces the idea of pipeline length |
[14:25:04] | clever: | the book i have for the 6502 explains the exact cycle count for every instruction |
[14:25:07] | clever: | in every addressing mode |
[14:25:27] | clever: | yeah pipeline realy screws the math up |
[14:25:44] | directhex: | short version: one reason p4 sucks is it has a HUGE pipeline |

[14:25:52] | clever: | but assuming you had the pipeline running perfectly, you could get 10 intructions/cycle (random number) |
[14:26:03] | directhex: | not your onw, as it's an older chip, but p4 ended up in its later days with a >30 stage pipeline |
[14:26:11] | clever: | directhex: so it takes 40 cycles to do even the simplest thing? |
[14:26:38] | directhex: | it takes 30 cycles to get warmed up, think of it like that. from empty to working there's a delay |
[14:26:38] | clever: | (just picking random guess numbers in what feels like the general area) |
[14:26:50] | clever: | yeah |
[14:27:01] | clever: | and if i have a jump, it will have to warm up again from scratch |
[14:27:11] | directhex: | the delay isn't enormously interesting, as you should keep your chip fed with data – unless something happens which causes a pipeline flush |
[14:27:24] | directhex: | clever, p4 does massive amounts of branch prediction, to try & avoid that |
[14:27:29] | clever: | ahh |
[14:27:41] | clever: | so i should only worry about pipeline flushing mainly? |
[14:28:15] | clever: | and i would expect that the kernel does a flush when doing a context switch(for multitasking) |
[14:28:28] | stuarta: | however, they team designing the core range of chips, threw out the p4 base and reworked the p3 base instead |
[14:28:45] | directhex: | i think they kept some of the RAM access concepts |
[14:28:55] | stuarta: | probably |
[14:28:56] | directhex: | but yes, the core ALU is all p3-inspired |
[14:29:07] | directhex: | core gets a whopping 4 FLOPs/cycle |
[14:29:13] | directhex: | assuming they're the right kind of FLOPs |

[14:30:33] | clever: | my only problems with the coppermine, its only 1ghz so it cant handle anything beyond 640x480 x264, and when it 'overheats' the whole system cuts power |
[14:31:36] | clever: | the Deschutes has 3 times as many cooling fans, and puts out enough heat to keep my closet toasty warm, but works great as a headless master backend |

[15:36:16] | wagnerrp: | im pretty sure i remember telling people they shouldnt buy a 5200 |
[15:36:32] | dustybin: | wagnerrp: why? i been using a 5200 for years |
[15:36:51] | wagnerrp: | most of them cant manage 1920x1080 digital |
[15:36:58] | dustybin: | oh ok |
[15:38:07] | dustybin: | i wonder if there is a such thing as a low profile / low width 8 series GF PCI card? if thats the case, i could still carry on using my mini HP frontend :) |
[15:38:32] | wagnerrp: | low width, meaning short? |
[15:38:36] | dustybin: | yep |
[15:38:46] | dustybin: | full width will not fit inside |
[15:39:04] | wagnerrp: | well full 'length' will not fit in most cases |
[15:39:36] | dustybin: | actually it would probably require a pci-e slot |
[15:39:40] | dustybin: | so no go |
[15:40:13] | wagnerrp: | or pci, although video acceleration on a pci is yet to be determined |
[15:40:30] | dustybin: | oh ok |
[15:41:41] | dustybin: | ebuyer has 8 series pci-e cards for £30, pretty dam cheap |
[15:41:59] | wagnerrp: | i would bet you have as much chance of getting video acceleration on a PCI card as you do an AGP card |
[15:42:24] | wagnerrp: | i believe they have the same bandwidth card-to-host |
[15:45:39] | dustybin: | I'm not going to do HD until, linux hardware acceleration becomes more mature, the cost of HDTV comes down, HDTV picture quality improves, MythTV .22 is released, Analogue TV switched off in UK, and UK HD TV becomes more available. Then, one will start work on HD :) |
[15:45:50] | wagnerrp: | seems newegg fixed their servers sometime overnight |
[15:46:10] | wagnerrp: | whats wrong with picture quality? |
[15:46:24] | fuxxy_: | hum. I had to recompile mythtv with xvmc support (gentoo), and now when I try to watch anything that uses xvmc, the frontend gets caught in a "prebuffering pause" |

[16:10:08] | fuxxy_: | wagnerrp, are you attaching it to FTA or to provider cable? |
[16:10:38] | wagnerrp: | well you dont need to worry about reception with cable |
[16:10:59] | fuxxy_: | wagnerrp, I understand, and in the attic you can elimate the need for a long cable run. |
[16:11:20] | wagnerrp: | well thats not trivial |
[16:11:38] | wagnerrp: | as mentioned, part of the rafter space is completely sealed off |
[16:12:05] | wagnerrp: | the rest of it is on the opposite side of a 4' ceiling exhaust fan that would have to be removed |
[16:12:13] | dustybin: | gregL: thanks |
[16:12:20] | fuxxy_: | wagnerrp, while there are no buttons, switches etc on the HDHR, only status lights, I feel you should still put it somewhere accessable. |
[16:12:26] | gregL: | dustybin:np |
[16:12:44] | wagnerrp: | exactly |
[16:13:51] | wagnerrp: | i wonder how much power that thing takes |
[16:13:54] | fuxxy_: | wagnerrp, and it's easer to run 1 cat6 cable to somwhere with mains power and ethernet, than it would be to run mains power and ethernet to the antenna. |
[16:14:05] | wagnerrp: | i could probably use some passive POE injector |
[16:14:08] | fuxxy_: | wagnerrp, not much at all, want me to check the back of the wallwart? |
[16:14:48] | wagnerrp: | considering its only 10/100, it only needs two of the pairs |

[16:18:50] | wagnerrp: | yeah, its really only supposed to do half that |
[16:19:37] | wagnerrp: | the PoE spec really only wants 400mA |
[16:20:19] | AndyCap: | yeah. and I guess futzing with 48V is going to be a lot of work. |
[16:20:45] | fuxxy_: | 48V? |
[16:21:08] | AndyCap: | well, I dunno if PoE is -48V or 48V. |
[16:21:22] | fuxxy_: | ahh. |
[16:21:49] | wagnerrp: | seems +48V |
[16:22:00] | wagnerrp: | -48V is really only used for telco equipment |
[16:22:10] | wagnerrp: | why they use negative... i have no idea |
[16:22:25] | AndyCap: | wagnerrp: which is why I wouldn't be surprised if PoE used it |
[16:22:30] | AndyCap: | wagnerrp: corrosion iirc. |

[16:45:29] | iamlindoro__: | MOAR? |
[16:45:43] | wagnerrp: | only 3K |
[16:46:47] | directhex: | wagnerrp, now, i have a machine room with about 320 1u or 1uish boxes |
[16:46:54] | directhex: | wagnerrp, plus my 256-core itanium |
[16:47:59] | AndyCap: | wagnerrp: that is more than twice as good. :> |
[16:49:42] | wagnerrp: | (estimating 500W) that dual quad xeon would also take nearly 40kW to run |
[16:50:20] | directhex: | fibre is silly expensive. i was somewhat surprised to see that the burnt out nortel xfp on my desk is a £1k part |
[16:50:28] | AndyCap: | it's not like you're running that over 802.3 PoE either |
[16:50:47] | AndyCap: | directhex: that's because it has excellent profits. |

[18:21:21] | Darthy: | yep.. true thing |
[18:21:37] | Darthy: | is there another solution i could get running on my via epia? |
[18:21:49] | justinh: | all I did for my frontend was install loonix on a hard disk, then copy / to an nfs share :) |
[18:22:26] | justinh: | the difference in size is nothing when you consider how many recordings you can get in a gig of space :P |
[18:23:26] | justinh: | some mythtv distros even have very convenient shortcuts to making diskless clients work |

[18:24:00] | d0nets: | anyone recommend the cheapest place to get a pvr 150 mce kit? |
[18:24:20] | d0nets: | there was one on ebay yesterday for 69 yesterday but now its gone and the cheapest i can find is 92 |
[18:24:40] | Darthy: | so you think i should have a look at knoppmyth and mythubuntu? |
[18:24:44] | justinh: | Darthy: nfsrooting is generally faster |
[18:25:09] | justinh: | Darthy: my frontend nfsroot is basically just a clone of a HDD-based mythbuntu install |
[18:25:21] | justinh: | boots up in less than a minute |
[18:25:36] | Darthy: | faster then what? atm im copying the whole ram image via tftp and decrunch it into a ramdisk |
[18:25:58] | Darthy: | how large is mythubuntu? |
[18:26:04] | justinh: | it's faster than that! |
[18:26:15] | Darthy: | ok..cool |
[18:26:39] | justinh: | remember the epia is a bit crap speed wise, so decompressing a big file takes a while |
[18:26:49] | justinh: | my net is only 100mbit here & boot time isn't too bad |
[18:26:57] | justinh: | and I've not chopped it down yet |
[18:27:05] | justinh: | there's plenty in init I don't need |
[18:27:37] | Darthy: | alright.. then you just just share the root of mythubuntu with nfs. which version should i currently use of mythubuntu? |
[18:27:57] | Darthy: | 8.1 or 9.04 alpha? |
[18:28:14] | justinh: | dunno – whichever matches your backend version |
[18:28:29] | Darthy: | i thought so.. :) |
[18:29:07] | justinh: | I uninstalled the myth packages & built it myself anyway |
[18:29:17] | justinh: | can't be arsed with all that ubuntu crap |
[18:30:59] | Darthy: | hmm.. i want mythtv to be installed quickly.. thats my main mission goal atm.. |
[18:31:05] | Darthy: | 600mb iso.. hmm |
[18:31:13] | justinh: | a good myth install cannot be rushed! |

[21:36:45] | iamlindoro__: | kormoc, Hmm, yeah, I see what's being referred to-- edges in MPEG-2 aren't very pretty (striping/blocking), and it's slightly worsened by lack of deinterlacing. |

[23:56:00] | ** sphery wants to play some XBox 360 vs MailingListJ (who's planning on hooking his game consoles up to RCA inputs on his analog capture cards and playing through Myth) ** | |
[23:57:30] | iamlindoro: | You can call him up and tell him you killed him before he finds out. |
[23:57:42] | iamlindoro: | SPOILER! |
[23:57:55] | sphery: | lol |

[23:59:19] | iamlindoro: | yeah |
[23:59:24] | sphery: | cool |
[23:59:24] | iamlindoro: | (and optical) |
