Can you put up for download a clip (50 MB or less) I can view? Here is the first 25 megs of an older clip that used to play before the update but now produces the problem. I figure using an older clip like this will be sure to rule out some weird problems with the input from the ivtv drivers. http://tokimi.jurai.org/~funaho/test.nuv What I get when I try to play it is a brief spurt of high-speed video (at least double speed if not faster) plus some audio; then the video pauses for a moment, the audio skips ahead and the whole cycle repeats. Thinking it might be related to audio changes I tried syncing the audio output portion of libmyth back to 11/15 (my last working version) but it didn't help. I also tried enabling Use video as timebase with no result. I have more memory showing up for this machine today so that compiling on it won't be so painful, and then I will try some more combinations including syncing libavcodec back to 11/15. Can anyone think of any other bits of code I should try reverting as well? ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] bad HDTV playback with new ffmpeg
My playback of this clip is definitely weird... playback speed seems to oscillate about 2 times a second. Deinterlacing or not doesn't seem to make much of a difference. Thank you for the confirmation. So, I guess I just happen to be the only one with a local affiliate broadcasting ATSC that's confusing the myth player. Wonderful. :/ Well I don't think it's just HDTV because I get this too ever since I upgraded to current CVS, and I'm running a PVR350. Video going fast and slow, sound skipping like mad...basically unwatchable. Still trying to nail it down...the suggestion of backing libavcodec back down to the 12/24 version didn't seem to help me either. I have the same problem since updating a few days ago. HDTV playback is not smooth. Does not jump around much, just slows down briefly. I get Prebuffer Pauses in the log when it happens. I tried the 12/24 version of the libavcodec tree but that did not help.

Re: [mythtv-users] bad HDTV playback with new ffmpeg
So I notice that 6 people downloaded the full length of this: http://www.krose.org/~krose/krose-cbs.mpg Is anyone else seeing the same weird effect I am when using Xv output? Keep in mind that this is happening to me on two different machines (one a dual Opteron running in 64 bit mode, the other a P4 HT, each with different audio chipsets), the main relevant commonality being that they are both using NVidia FX video cards with the 6629 driver. I've only seen it so far with CBS football broadcasts, and nothing else. Even other 1080i content (e.g., ABC football broadcasts) looks fine.

FWIW, PBS HD (which is definitely 1080i) also works fine. Kyle ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Given that I'm not using a hardware MPEG decoder (for which libavcodec does nothing), I think (a) these are probably disparate problems and (b) libavcodec probably doesn't have anything to do with your problem. Can you think of anything else you changed when you upgraded to the new CVS? Downgrading should help if that's the case. What version of ivtv are you using?

Actually I'm not using the decoder on the PVR350, just the encoder right now. Decoding is software to a Geforce FX card, driver version 6111 (which I've been running for ages now.) I'm running ivtv 0.2.0-rc3c, which was running for several days before I upgraded Myth so I'm sure it's not that either (not that should matter since I'm not using hardware decoding.) Nothing else was changed at the time I upgraded Myth. I was running CVS from around thanksgiving (11/22 if I'm not mistaken) and upgraded to 01/04. Subsequently backed down libs/libavcodec to 12/24 as per another post I saw on this exact same problem but still get the weirdness. I've thought about backing down to the previous version since I still have the RPMs I made but I stupidly forgot to backup my database and now the schema has upgraded. I'm not worried about it though; it's still recording all my shows for me and I can live without TV for a while. :) Hmm on the bright side I *finally* got MythMusic working. That's a definite plus...it never worked for me until today. ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

[mythtv-users] bad HDTV playback with new ffmpeg
Three users unsuccessfully attempted to download the mpeg fragment that I posted today that demonstrates (on two of my machines) a difference between pre-Dec 24 and post-Dec 24 ffmpeg sync-ups when using Xv output. I was working with a new dmz config that didn't have the mpeg in my public_html directory. Here's the link again: http://www.krose.org/~krose/krose-cbs.mpg Let me know if there are any problems.
