Revision 14692 causes blue faces in .wmv files

[Mike Rice <mikerice1969@…>]

The blue faces occur only in .wmv files not .mpg/.avi and occur on both my Intel and NVIDIA cards. Before the code was choosing I420 but now YV12. Maybe this isn't a bug but a setting I need to set in xorg.conf or something? A few people have seen this issue other than me. I've attached a log with both versions.

Does this problem appear when using ffplay to play the video?

ffplay displays the videos with the correct colors (as does mplayer) on both Intel and NVIDIA. I just installed ffmpeg.i386 version 0.4.9-24_r8743.fc8 from atrpms to verify. (I don't know how that matches up to what is in mythtv trunk).

strange, the atrpms ffmpeg is just one revison off from the libav* copies before the latest major ffmpeg sync. Current mythtv trunk uses ffmpeg rev 11051.

Since there is quite a difference between those revisions, please try again with ffmpeg from svn revision 11051.

Are the wmv files from a common source?

I first noticed this in my son's claymation movies he made with Windows Movie Maker. The only other .wmv file I have at the moment is the "swear jar" commercial someone posted a link to awhile back. I put that at the URL below if you want to take a look:

​http://home.comcast.net/~mikerice1969/swear_jar_300k.wmv

It is a 1 min/2.5Mb clip.

I can try with a different ffmpeg version but that might take me awhile.

Just built ffmpeg 11051 and the colors are correct (no blue faces) there as well.

(In [15303]) Fixes #4214. Some old, not so frequently used, code for indirect rendering in MythTV was improperly initializing a temporary frame for colour conversion. This caused blue faces when playing back some wmv files when the UV's weren't a I420 order, this could also cause segfaults with the VIA XVideo implementations.
