kgbudz: |
and its working |
| [00:00:00] |
scopeuk: |
ok |
| [00:00:00] |
kgbudz: |
for some reason, this certain show |
| [00:00:00] |
scopeuk: |
hmm |
| [00:00:00] |
kgbudz: |
errors |
| [00:00:00] |
scopeuk: |
sam tuner? |
| [00:00:00] |
kgbudz: |
yup |
| [00:00:00] |
kormoc: |
is it a bad recording? |
| [00:00:00] |
marmoset: |
xris: you have a second for a nuvexport question? |
| [00:00:00] |
kgbudz: |
no, im doing mpeg2 lossless commercial cut |
| [00:00:00] |
xris: |
marmoset: depends on what it is. ask away. |
| [00:01:00] |
kgbudz: |
like where would i find details on this error? |
| [00:01:00] |
marmoset: |
xris: on a frontent machine it's saying no valid recordings available, any common causes? |
| [00:01:00] |
marmoset: |
er, frontend |
| [00:01:00] |
marmoset: |
works fine on the backend machine |
| [00:01:00] |
kormoc: |
kgbudz, you could try running it by hand |
| [00:01:00] |
kgbudz: |
how do i do that? |
| [00:01:00] |
kgbudz: |
whats the command |
| [00:02:00] |
kgbudz: |
marmoset, ive had that problem, i could be wrong, but i believe nuvexport doesnt run remotely... |
| [00:02:00] |
marmoset: |
oh, maybe it doesn't |
| [00:02:00] |
kormoc: |
kgbudz, that I wouldn't know |

kgbudz: oh, ok, maybe that's it. I used it in the past remotely, but I think I was telling it the files specifically on the command line (as part of a userjob) |
| [00:03:00] |
kgbudz: |
i thought nuvexport was interactive only...? |
| [00:03:00] |
xris: |
marmoset: files mounted in the correct location? |
| [00:04:00] |
marmoset: |
nah, you can specify everything, I had it auto-reencoding stuff a while ago :) |
| [00:04:00] |
xris: |
kgbudz: works fine remotely. |
| [00:04:00] |
kgbudz: |
like i used to run nuvexport and it wouldnt list episodes on my slave server |
| [00:04:00] |
kgbudz: |
it would only list episodes on the master |
| [00:04:00] |
marmoset: |
kgbudz: ah, that's what I want tho |
| [00:05:00] |
kgbudz: |
like i had all the slave video directories nfs'ed on the master |
| [00:05:00] |
kgbudz: |
same locations |
| [00:05:00] |
marmoset: |
xris: yeah, everything's mounted fine as far as I can tell, the frontend plays just fine. Does it use a DB entry or a find to figure out what to reencode? |
| [00:05:00] |
xris: |
kgbudz: it can only interact with files on the machine. |
| [00:05:00] |
kgbudz: |
right, thats what i figured |
| [00:05:00] |
xris: |
marmoset: it looks for RecordFilePrefix (which would be /path/to/recordings/) for the current host. |
| [00:05:00] |
xris: |
compares the files in there vs what it sees in the db. |
| [00:05:00] |
marmoset: |
ok, thanks, I'll check that out |

xris, i noticed that mpeg2 commercial cut has been removed from the latest nuvexport??? |
| [00:07:00] |
xris: |
kgbudz: yeah. mythtv does it natively now. |
| [00:07:00] |
kgbudz: |
ya, thats the job which is erroring for me right now |
| [00:07:00] |
kgbudz: |
trying to figure out a way to get this show commecial cut |
| [00:08:00] |
marmoset: |
xris: sweet, that was it, RecordFilePrefix was wrong for that front end for some reason, fixed it and it comes up fine |
| [00:08:00] |
marmoset: |
thanks |
| [00:09:00] |
marmoset: |
xris: I mentioned to ken and art the other day that we were buying servers from you guys because of this channel ;) |
| [00:09:00] |
xris: |
L) |
| [00:10:00] |
xris: |
marmoset: I think he knows. mythtv has been good to simech. this channel got me kormoc, too. |
| [00:10:00] |
xris: |
a fair amount of mythweb code is paid for by simech, too. |
| [00:10:00] |
marmoset: |
nice |
| [00:10:00] |
marmoset: |
I like mythweb |
| [00:10:00] |
kgbudz: |
i think i just broke my backend |
| [00:10:00] |
xris: |
that's one reason why I LGPL'd a bunch of mythweb's libraries. makes it simpler for bringing code back and forth from work. |
| [00:11:00] |
kgbudz: |
everytime it starts up, it tries running this job |
| [00:11:00] |
kgbudz: |
which crashes it |
| [00:11:00] |
xris: |
kgbudz: stop the backend, delete the job from the jobqueue table. |
| [00:11:00] |
kgbudz: |
o werd |
| [00:11:00] |
kgbudz: |
i will try that |

granted, the plasma tv hasn't been there for a week or so. |

lol, I'd love that. no, just some random hardware and a 250G drive. |
| [00:14:00] |
xris: |
might need more drive space if I ever have time to put this hd5000 card in, though |
| [00:14:00] |

I think we're up to 6 of those beasts now |
| [00:14:00] |

those are nice machines. would LOVE one for my garage. |

couldn't even get one when a table broke and 2 fell off.... |

guy next to it caught one of them (impressive, considering they weigh 80+ lbs), but 2 slid off onto the floor and got some nasty dents in the case. |

no idea what happened to them. insurance, probably. |

xris: |
marmoset: yeah, I'm glad that they finally added that... only other option like that with OS drives was a nasty ASI case that was basically a 4u bolted to a 1u.. and I think it was extra-wide and wouldn't fit into most racks. |
| [00:18:00] |
rsquared: |
kormoc: that thing just uses a CI Designs chassis |
| [00:18:00] |
xris: |
rsquared: yes |

hmm, maybe not ASI.. I forget the brand. that old one with the purple handles on the drive carriers. |

how much space you got on that machine? |

| [00:20:00] |
marmoset: |
kgbudz: we've got 8TB on each of ours |
| [00:20:00] |
marmoset: |
depends on the drives you put in tho |
| [00:20:00] |
Jasper: |
hmm I think bmk789 is gonna have a hard time writing his OS kormoc :P having no experience at all |
| [00:20:00] |
marmoset: |
and if you use raid 10 vs raid 5, etc |
| [00:20:00] |
rsquared: |
marmoset: nice.. we're thinkin of building one for backup staging |

im building from debian, i know debian pretty well |

So i'm trying to get a remote front-end working. I've got mysql listening on eth0, and setup a mysql user for myth@%, the front end now gets further and brings up the menu, but when i try to do anything e.g. Watch Live TV, it says it can't connect to the backend... but it is connected right? |

no firewall im aware of. didn't have to do anything to open up mysql, except get mysql itself listening on eth0 |

bmk789, if you're gonna make this a general distro, you'll want to use qemu with kqemu rather then make it xen aware. |
| [00:24:00] |
bmk789: |
qemu works in gentoo? |
| [00:25:00] |
kormoc: |
of course |

cool |
| [00:26:00] |
kgbudz: |
has anyone else had a problem with the frontend being extremely sluggish on .19? |
| [00:26:00] |
xris: |
you have to run it on each box you configure for mythtv |
| [00:26:00] |
xris: |
need to tell it where the backend is. |
| [00:26:00] |

i wonder if you could take a 1394 controller, remove the chip and add one that had 5c |

but bmk789 what's gonna be special on your distro? |

| [00:27:00] |
aVirulence: |
no one has an idea about my database problem? |
| [00:27:00] |
danThePerson: |
yeah it asked on the first run, and i put in the backend server name. It connects to the backend server, and then trys to connect to localhost once it has connected as you can see in the console log |
| [00:27:00] |
bmk789: |
itll have mythttv openmosix and stuff pre-setup, ill write some easy UI software in java too |

hmm... so the front-end connects to the backend, and then asks the backend for the ip of the backend server? |

bmk789, you'll lose a lot of performance via latency |

bmk789: |
not much with gigabit |

bmk789, sending a raw 800x600x32 frame takes 117.1875 megabites per frame. You would saturate gigabit at 9 frames per second |

where do you get those values from? |

| [00:39:00] |
marmoset: |
bmk789: it doesn't need to be openmosix aware |
| [00:39:00] |
marmoset: |
er |
| [00:39:00] |
marmoset: |
kormoc: it doesn't need to be openmosix aware |
| [00:39:00] |
marmoset: |
it's transparent |
| [00:39:00] |
aVirulence: |
xris, erm, would you happen to know what query I should use for that? |
| [00:39:00] |
kormoc: |
marmoset, it's not threaded, so eather it needs to be redone as threading or openmosix aware |
| [00:39:00] |
marmoset: |
nope |
| [00:39:00] |
kormoc: |
ooh? |
| [00:39:00] |
dasOp: |
nothing is truly transparent |
| [00:39:00] |
marmoset: |
I know |
| [00:40:00] |
marmoset: |
but openmosix migrates processes not threads |
| [00:40:00] |
marmoset: |
and only if they meet certain conditions |
| [00:40:00] |
kormoc: |
how would it split a process among many computers then? |
| [00:40:00] |
dasOp: |
yes. it still isnt gonna help a regular single threaded app one bit |
| [00:40:00] |
marmoset: |
it doesn't |
| [00:40:00] |
kormoc: |
that's his goal |
| [00:40:00] |
marmoset: |
not gonna work |
| [00:40:00] |
marmoset: |
unless there's multiple things encoding at once |
| [00:41:00] |
marmoset: |
it's possible you could use a parallel library |
| [00:41:00] |
marmoset: |
like mpi |
| [00:41:00] |
marmoset: |
but I don't know if anyone's gotten that to work |
| [00:41:00] |
dasOp: |
and as marmoset says, there's way too many passes and too much lookahead involved in hd encoding for it to parallelize properly |

bmk789: |
ok if y'all wwanna put down my OS, do it in #medeix |
| [00:41:00] |
marmoset: |
bmk789: I'm not saying don't do it, just that there's a lot of complexity :) |
| [00:42:00] |
dasOp: |
you could chunk up the input, if you're willing to accept the overhead of massive encoding restarts |
| [00:42:00] |
marmoset: |
bmk789: I'd also recommend waiting until the next version of openmosix is out, it'll be a huge improvement for you |
| [00:42:00] |
marmoset: |
since it'll be 2.6 instead of 2.4.26 |
| [00:42:00] |
dasOp: |
that'd work fine with mpi |
| [00:42:00] |
Jasper: |
LOL |
| [00:42:00] |
Jasper: |
:P |
| [00:42:00] |
dasOp: |
(if the transcoding app was mpi aware :P) |
| [00:42:00] |
Jasper: |
wwhe medeix bmk789 ? |
| [00:43:00] |
dasOp: |
which I doubt any app in that category is |
| [00:43:00] |
Jasper: |
why even |
| [00:43:00] |
bmk789: |
wwhe? |
