| [00:01:27] | poptix- is now known as poptix | |
| [00:14:53] | jpabq: | skd5aner, For me, HD-PVR recordings made with 0.24 *start* playing back very jerky with 0.26. However, if I save the position, and restart playback it works fine for me. That is what finally prompted me to fix the problem with the HD-PVR signal monitor so it didn't Start / Stop / Start recording at the beginning of each program. |
| [00:15:23] | jpabq: | That Start / Stop / Start caused time-code damage which now causes playback to be very jerky. |
| [00:15:52] | skd5aner: | I think my HDPVR is still doing that |
| [00:15:57] | jpabq: | So, recordings made with 0.26 playback fine for me, since that timecode damage doesn't happpen now. |
| [00:16:24] | skd5aner: | I showed the same problem with recordings made earlier as well as new recordings |
| [00:16:51] | skd5aner: | I didn't go back further than a month, which would have had recordings from a different STB and cable provider, but I did try 0.25 and 0.26 recordings with the same issue |
| [00:16:55] | jpabq: | Yeah, I saw that in your ticket. I can't explain why I don't have that problem. |
| [00:17:08] | skd5aner: | 1/15 tries and I could get it to play back after I repositioned the playback (as you stated) |
| [00:17:31] | skd5aner: | I sent stuartm a file, wonder if it'd tell you anything |
| [00:17:41] | skd5aner: | I just rolled back to 0.25, and playing back just fine once again :/ |
| [00:17:46] | jpabq: | I will download your sample from stuartm and see if I can play it. |
| [00:18:06] | skd5aner: | it was recorded with 0.26, btw |
| [00:18:18] | skd5aner: | if that matters |
| [00:26:07] | jpabq: | skd5aner, VDPAU? |
| [00:26:35] | skd5aner: | yes sir |
| [00:26:52] | skd5aner: | although, in 0.26 I changed it to "standard" and opengl and saw the same thing happen |
| [00:27:36] | jpabq: | I tried playback with mythavtest and VDPAU and it segfaulted. With "normal" it played okay |
| [00:31:15] | skd5aner: | ah, you got the file? |
| [00:31:41] | skd5aner: | I wasn't seeing segfaults... although I'd almost prefer that I did over the jerkiness ;) |
| [00:32:05] | jpabq: | Okay, I just tried it on a my "dev" box which is actually running Fedora 16 instead of 17, and a few week older version of Myth. I can reproduce your problem there. The behavior is different (but similar) than what I see on my production machine with *older* recordings. |
| [00:32:25] | jpabq: | I will update Myth on that box and see if that changes anything. |
| [00:32:26] | skd5aner: | ok, good deal... |
| [00:32:44] | skd5aner: | I'm running ubuntu 12.04 and compiling -fixes on my own |
| [00:32:50] | skd5aner: | as a baseline |
| [00:42:18] | jpabq: | That file is definitely damaged. So, there are two problems: 1) Why are your HD-PVR recordings damaged. 2) Why doesn't Myth recover. |

| [00:54:11] | skd5aner: | jpabq: btw I downgraded to 0.25 and the sample clip plays fine from the start. There is a very slight blip within the first second, but it's not really noticable |
| [00:56:36] | jpabq: | skd5aner, we may have to ask for taylorr's help. I am betting this is a time-code issue, and he knows a LOT more about that stuff than I do. |
| [00:57:20] | skd5aner: | cool – thanks for diving in so quickly |
| [01:13:18] | taylorr: | jpabq, skd5aner: yes, there is one thing to try |
| [01:14:30] | taylorr: | skd5aner: try starting mfe with the following -> FORCE_DTS_TIMESTAMPS=1 mythfrontend |
| [01:16:39] | jpabq: | taylorr, assuming that also works with mythavtest, then it didn't help. |
| [01:17:20] | taylorr: | jpabq: do you have a link to the file? |
| [01:18:16] | jpabq: | taylorr, I don't know if it will work, but I just send you an email. |
| [01:24:03] | taylorr: | jpabq: I just added you as a collaborator for my share file... can you try to upload to my folder? |
| [01:24:16] | taylorr: | you should have an e-mail |
| [01:24:31] | jpabq: | yup. trying now |
| [01:26:00] | jpabq: | It is working on it. My upload speed is not that fast. |
| [01:27:19] | taylorr: | thanks, no rush... I'm having to re-compile 0.26 from an old checkout so it'll be awhile before I can test it |
| [01:35:33] | jpabq: | taylorr, done |
| [01:37:30] | taylorr: | got it, thanks |
| [01:40:36] | taylorr: | jpabq: is the problem purely segfault related? |
| [01:41:08] | jpabq: | No, although I did experience a segfault with it. It is VERY jerky when played back. |
| [01:43:36] | Beirdo: | dekarl: you in? |
| [01:44:22] | taylorr: | jpabq: that file causes a segfault with 0.25-fixes too |
| [01:47:00] | jpabq: | taylorr, I had it segfault with VDPAU, but it played with "normal". Then I tried VDPAU again and it played. I will try it again now. |
| [01:49:32] | taylorr: | jpabq: vlc on my laptop is complaining about "Width/height changing with threads is not implemented" – so I'm guessing now we have multi-threaded decoding that the Width/height is changing during playback and causing the issue |
| [01:51:26] | jpabq: | taylorr, weird. skd5aner says this was recording using myth from his HD-PVR. |
| [01:51:51] | taylorr: | jpabq, skd5aner: does this video just show a static screen... looks like ffplay has issue with the video too |
| [01:52:19] | taylorr: | jpabq: if it's indeed ESPN then I'm not sure why it is 720x480 at the very start |
| [01:53:01] | jpabq: | skd5aner, how long is the sleep at the bottom of your channel change script? Also, what kernel are you running? |
| [01:55:48] | taylorr: | jpabq, skd5aner: if I strip the first 10MB off then it plays fine :) |
| [01:57:32] | taylorr: | so the original file reports rez being 720x480 and the file with 10MB stripped from the start reports 1280x720 |
| [01:58:41] | taylorr: | does anyone know how to compile mythtv with h.264 multithreaded decoding disabled? |
| [01:59:03] | jpabq: | taylorr, I have a similar problem with playback of shows recorded with 0.24. However, for me, if I save the recording after the "damage" and then re-start playback, everything is fine. skd5aner says that doesn't work for him... |
| [02:00:20] | taylorr: | jpabq: if you run mediainfo against your 0.24 recordings does it have a different start resolution? |
| [02:02:52] | jpabq: | taylorr, where do I get mediainfo ? Doesn't show up via a "yum whatprovides" query. |
| [02:04:13] | taylorr: | jpabq: I think it might be available via the mediainfo homepage |
| [02:05:09] | taylorr: | jpabq: http://mediainfo.sourceforge.net/en/Download |
| [02:05:38] | taylorr: | Beirdo: do you know how to get mythtv to build ffmpeg without multi-threaded decoding? |
| [02:05:52] | taylorr: | like it was for 0.24 |
| [02:13:45] | jpabq: | taylorr, I just spot-checked a dozen files, and they all show the correct resolution. |
| [02:15:21] | taylorr: | jpabq: ok, when encountering issues with these files it's a good idea to get logs with -v playback,libav --loglevel debug so that you can see what ffmpeg decoding errors are being detected |
| [02:17:13] | jpabq: | taylorr, thanks. skd5aner ^^^ |
| [02:17:23] | taylorr: | I imagine these issues surfaced when ffmpeg turned on multi-threading for h.264 decoding and the only way to get them fixed properly is to submit samples to ffmpeg... just make sure that mythffplay shows issues so they can recreate |

| [02:34:16] | taylorr: | thanks – schedtool -a 0x1 set the affinity to CPU0 |
| [02:35:03] | taylorr: | jpabq: ok, after installing 0.26 mythffplay is working fine |
| [02:42:15] | taylorr: | jpabq: I'm just now getting 0.26 up and running so I'll take a deeper look either tonight or in the morning to see what I can find |

| [03:48:45] | taylorr: | actually I'm not sure about VDPAU... the gpu on my laptop doesn't have enough resources to play it (only 256MB video memory) |
| [03:49:04] | taylorr: | it plays fine on 0.25 with VDPAU |

| [15:03:09] | gigem: | taylorr: The reason for the 720x480 part at the beginning of skd5aner's recording is probably a local commercial. When I had Time Warner, their local commercials were always 480i no matter what the channel normally is. skd5aner: you can probably avoid that problem by configuring your STB to always use either 1080i or 720p. If it's a motorola box, there are two settings — you need to set the desired |
| [15:03:11] | gigem: | resolution and also disable the "4x3" override. |

| [21:27:22] | skd5aner: | taylorr, jpabq: sorry, I was away most of the evening and day today.... |
| [21:28:12] | skd5aner: | taylorr, jpabq: I have already rolled back to 0.25... not sure it'd be very easy for me to upgrade again to 0.26 as I only have the one setup and not a seperate dev environment |
| [21:30:27] | skd5aner: | taylorr, jpabq: You were asking about my channel change script. When I moved, I stopped using my old SA script and started using the built-in firewire channel changing capability that was added as of 0.25 – http://code.mythtv.org/trac/changeset/d49f3f2 . . . 70407/mythtv |
| [21:30:35] | skd5aner: | so, there is no sleep |
| [21:30:39] | taylorr: | skd5aner: are you sure you performed a clean 0.26 install by wiping all 0.25 libraries, etc? also did you perform a distclean before compiling? |
| [21:30:51] | skd5aner: | I did two things... |
| [21:31:02] | skd5aner: | make uninstall in my 0.25-fixes dir... |
| [21:31:47] | skd5aner: | then, did an "ls -l /usr/{,local/}lib/{mythtv,libmyth*} /usr/{,local/}include/mythtv |
| [21:31:47] | skd5aner: | " |
| [21:31:58] | skd5aner: | made sure no libraries were remaining |
| [21:32:15] | skd5aner: | then, checked out 0.26-fixes in a new directory, and compiled from scratch there |
| [21:33:09] | skd5aner: | My STB does have an OSD that comes on after the channel change, I've set it to "short" for length of time it is displayed, but I'm wondering if that's not part of the problem |
| [21:33:12] | taylorr: | cool, everything should have been fine then... did you get playback logs with -v playback,timestamp,libav --loglevel debug when you had 0.26 installed? |
| [21:33:25] | skd5aner: | only -v playback unfortunately :( |
| [21:33:36] | skd5aner: | I'm sorry I didn't grab more at the time |
| [21:34:00] | taylorr: | skd5aner: I didn't have any issues playing back your video with 0.26-fixes using the standard ffmpeg decoder |
| [21:34:04] | skd5aner: | I could upgrade again, now... re-run it, and downgrade before primetime starts in 2.5 hours |
| [21:34:11] | skd5aner: | taylorr: as an FYI, they all playback fine in 0.25 |
| [21:34:21] | taylorr: | skd5aner: send me link to that log then |
| [21:34:55] | skd5aner: | it's on the ticket... #11159 |
| [21:34:55] | ** MythLogBot http://code.mythtv.org/trac/ticket/11159 ** | |
| [21:35:11] | skd5aner: | do you want me to try and upgrade to grab more logs? |
| [21:35:24] | skd5aner: | I tries OpenGL with the same results |
| [21:35:32] | skd5aner: | er, "tried" |
| [21:38:29] | taylorr: | skd5aner: did you check your CPU utilization? |
| [21:38:50] | taylorr: | a great way to do so is with Mark's "Playback data" screen he added |
| [21:38:56] | skd5aner: | Not that I recall, although VDPAU typically keeps it very low |
| [21:39:09] | skd5aner: | taylorr: I forgot about that... how do I even access it and does it require a specific theme? |
| [21:39:12] | taylorr: | it gives you a lot of very good details about what's going on |
| [21:39:25] | taylorr: | Menu->Playback, IIRC |
| [21:39:39] | taylorr: | you can bind a key but I just use the menu as needed |
| [21:40:04] | skd5aner: | taylorr: so you coudln't replicate the issue with the sample? |
| [21:40:14] | skd5aner: | jpabq: could on one machine, but not another |
| [21:40:29] | taylorr: | nope, but I couldn't get VDPAU to playback the file on my laptop since it's only got 256MB video memory |
| [21:40:38] | skd5aner: | ah |
| [21:41:33] | skd5aner: | I think you may have also been asking about kernel version... I'm on ubuntu 12.04, running kernel 3.2.0 |
| [21:41:35] | taylorr: | if you playback profiles have been untouched, it would be interesting if "VDPAU Slim" works or not |
| [21:41:55] | skd5aner: | Yea, I didn't muck with them until after the problem... |
| [21:42:08] | skd5aner: | I've got a GT240 with 512MB of memory if I recall correctly |
| [21:43:17] | skd5aner: | ok, I'll upgrade again... before I do, tell me exactly what you need me to get for you |
| [21:44:08] | taylorr: | just a log with the specifics I mentioned a little earlier.... also check "Playback data" to see if anything useful shows up |
| [21:46:05] | skd5aner: | k |

| [22:56:41] | Beirdo: | gah, nice to have my work laptop crap out on me |
| [23:07:48] | taylorr: | skd5aner: another clip is fine. |
| [23:08:31] | skd5aner: | taylorr: I switched to Normal, and everything works |
| [23:08:38] | skd5aner: | so, appears to be an issue with VDPAU |
| [23:09:02] | skd5aner: | taylorr: I think I'll stay on 0.26 and just use normal, that way if I need ot test I don't have to keep going back and forth |
| [23:15:48] | skd5aner: | taylorr, jpabq: more detailed logs uploaded to #11159, and I've also added some additional details to the ticket |
| [23:15:48] | ** MythLogBot http://code.mythtv.org/trac/ticket/11159 ** | |
| [23:28:30] | taylorr: | skd5aner: is this a typo "Frames decoded/free: 4/2"? What does that field have under VDPAU Normal? |
| [23:29:20] | skd5aner: | let me try again... |
| [23:30:55] | skd5aner: | taylorr: right now it's showing 2/2 |
| [23:31:09] | skd5aner: | now 7/2 actually |
| [23:31:24] | skd5aner: | and that's VDPAU High Quality |
| [23:31:29] | skd5aner: | I can switch it to Normal... |
| [23:31:41] | Beirdo: | Hmm |
| [23:32:04] | Beirdo: | I've seen similar occasionally on recordings that seem to have a glitch in them |
| [23:32:34] | Beirdo: | if I save location, exit playback, and restart from the bookmark, it clears up until the next glitched frame |
| [23:32:37] | Beirdo: | or so it seems |
| [23:32:38] | taylorr: | skd5aner: did you still have "vdpaubuffersize=32" set in the playback profile? |
| [23:32:59] | skd5aner: | taylorr: 1/2 in frames decoded/free in VDPAU Normal |
| [23:33:11] | skd5aner: | that field sometime changes |
| [23:33:27] | skd5aner: | ooh, just created a segfault but skipping back |
| [23:33:32] | Beirdo: | but that was maybe on 1–2% of my HDPVR recordings, so I didn't bother reporting it, and I don't know that I've seen it for a few weeks |
| [23:33:33] | skd5aner: | s/but/by |
| [23:34:23] | skd5aner: | I'm wondering if this is just on 720p content... because I just tried a few 1080i recordings and they played back fine |
| [23:35:07] | Beirdo: | Ooh,I hadn't tried to correlate with resolution either. |
| [23:35:24] | skd5aner: | nope... |
| [23:35:26] | skd5aner: | nevermind |
| [23:35:43] | skd5aner: | got a 1080i recording to mess up... I just had to start it from the begining, not from the bookmark |
| [23:36:14] | skd5aner: | taylorr: perhaps, but isn't that setting completely ignored now? |
| [23:36:24] | Beirdo: | maybe something's messed up in the first few frames while the hdpvr locks? |
| [23:36:37] | taylorr: | skd5aner: I believe that setting should be ignored now |
| [23:36:45] | skd5aner: | taylorr: I think danielk22 actually changed that setting to a new name in 0.25 to accomidate for people that still wanted to override the automatic setting, but at least so it'd ignore the old setting if anyone still had it set |
| [23:37:38] | taylorr: | skd5aner: the HQ scaling definitely puts stress on the GPU so you might want to see if removing that helps any |
| [23:38:09] | skd5aner: | Beirdo: perhaps, I woudn't be surprised if the HD-PVR doesn't play nicely when the STB isn't stabilized and/or when the STB timesout the OSD after channel changes |
| [23:38:40] | Beirdo: | it wouldn't be the first time we've seen odd effects, but this one is fairly new :) |
| [23:38:53] | taylorr: | skd5aner: playback data only showing 2–4 decoded frames isn't good and I believe it means that VDPAU isn't keeping up since you should see something around 12 |
| [23:39:10] | skd5aner: | taylorr: it exhibits the same behavior in VDPAU Normal, which has 0 filters configured |
| [23:40:04] | taylorr: | let me check my main frontend running 0.25 with your sample and see what I'm getting |
| [23:40:33] | taylorr: | skd5aner: is this a remote frontend? |
| [23:40:37] | skd5aner: | Interesting... |
| [23:40:57] | skd5aner: | I just switched to OpenGL and it gliched for the first second a few times, very similiar to VDPAU, but now it's normalized and is playing back fine |
| [23:41:07] | skd5aner: | "OpenGL Normal" |
| [23:41:24] | taylorr: | what does the decoded/free give you? |
| [23:42:07] | skd5aner: | Frames Decoded/free is 13/1 on opengl, decoder says ffmpeg |
| [23:42:14] | skd5aner: | (on playback data OSD) |
| [23:42:44] | taylorr: | yes, that's much more ideal for smooth playback... is this a remote frontend? |
| [23:42:59] | skd5aner: | It's a SBE/FE, but it is remote from the MBE and storage |
| [23:43:15] | taylorr: | also, have you rebooted your frontend since this problem surfaced? |
| [23:43:22] | skd5aner: | I have not |
| [23:43:52] | skd5aner: | althought I've upgraded and downgraded mythtv twice :) always works with 0.25, always doesn't with 0.26 |
| [23:44:14] | skd5aner: | I can reboot if you'd like though, and do an apt-get dist-upgrade to make sure everything is up to date in the OS |
| [23:47:23] | taylorr: | skd5aner: it just seems like it's the hardware not keeping up at this point. |
| [23:47:39] | skd5aner: | why the difference between versions though? |
| [23:48:17] | skd5aner: | and a GT240 seems to be overkill for almost all broadcast TV |
| [23:48:19] | taylorr: | no idea... there really shouldn't be |
| [23:48:39] | taylorr: | that's why I'm wondering if the system needs rebooting |
| [23:49:06] | skd5aner: | updating now – will reboot in a moment – I'll even do a cold reboot, just to completely power down the board and everything |
| [23:49:23] | taylorr: | the only reason the decoded frames should be low is if the data being fed to the decoder is slow or the decoder itself is having issues |
| [23:49:29] | skd5aner: | I know it also has to do a hard drive test this reboot, so it'll take a bit |
| [23:50:28] | taylorr: | skd5aner: that's fine, maybe jpabq can tell us what he gets for decoded/free under 0.26 |
| [23:50:59] | skd5aner: | Beirdo: FYI, occasionally (very rarely) I can jump to a later point in the recording, stop the recording, start the recording, and it plays back fine, but not that frequently |
| [23:51:12] | taylorr: | hmmm, I just thought of something, if the video is damaged then ffmpeg may not be releasing buffers and that's why the decoded/free is so low |
| [23:52:22] | skd5aner: | yea, but that was my thought (and jpabq's as well) – could the ffmpeg sync shipped with 0.26 be less robust in dealing with damaged video than it previously was? |
| [23:52:40] | skd5aner: | (... in 0.25) |
| [23:57:06] | taylorr: | yes, I'm now looking at the log you just posted and that file is causing a ton of limbo frames... meaning the decoder never returned them... so you should see the decoded and free add up to 16 but you are seeing things like 2/2 or 4/2 which means a ton of the video buffers are lost |
| [23:58:55] | taylorr: | adding more buffers would probably make it play back better but if a video is damage throughout it's just a matter of time before they exhaust |
| [23:59:11] | skd5aner: | I'm not sure that's the case though |
| [23:59:26] | skd5aner: | I see a glitch at the begining of the video, first ~2 seconds, on other renderes |
| [23:59:47] | taylorr: | skd5aner: if you play from the beginning do you get low decoded/free numbers but if you start from the middle do you get hight numbers? |
| [23:59:48] | skd5aner: | my guess is it's still a stabilization issue with the STB |
