Description
Multiple Danish MythTV users have recently reported playback issues on 0.24-fixes with at least two Danish FTA channels (DR1+DR HD).
Below is a small sample of a recording which briefly has a pixelated picture when being played with the VDPAU profile. The sample doesn't give any pixelation on playback when a non-VDPAU playback profile is being used. Playing the clip with mplayer+VDPAU (mplayer -vo vdpau -vc ffmpeg12vdpau) doesn't give any pixelation either. Changing the vdpaubuffersize has no impact on the issue.
In the attached log (generated with "-v playback,extra"), the pixelation happens at around 17:30:22, but there doesn't seem to be any obvious errors at that time.
This has only been tested on 0.24-fixes, as I don't have access to a VDPAU-capable machine running master. The user who created this sample was also running 0.24-fixes.
The 20MB sample can be downloaded from the following link (scroll down on the page and click on "Regular download"): http://www.crocko.com/017DEE17AAAE4D6D83ED35EDA399B9F6/DR1_sample_with_VDPAU_playback_issues.mpg

Using latest git master, the sample shows corruption using ffmpeg software decoding, VDPAU and VAAPI. Seems to play without issue on other players though - so I'm guessing that this is related to the version of ffmpeg we're running.
