[mythtv] Help with unknown codec

With the latest SVN update, I am no longer able to play avi files with
the internal player through mythvideo. I'm not sure why, or what
changed, but pretty much all I see in the log is this:
AFD: InitVideoCodec() 0x91a5880 id(Unknown Codec ID) type (Video).
When the file is opened initially, and then thousands of these:
AFD: No codec for stream index 0, type(Video) id(Unknown Codec ID:14)
Now, I've poked around in libavformat and libavcodec, but I can't see
where codec ID's are matched with a type. If I look at one of the avi's
with mplayer I get:
AVI file format detected.
VIDEO: [DX50] 512x328 24bpp 25.000 fps 744.7 kbps (90.9 kbyte/s)
Clip info:
Software: VirtualDubMod 1.5.10.1 (build 2366/release)
==========================================================================
Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
Selected video codec: [ffodivx] vfm: ffmpeg (FFmpeg MPEG-4)
another one that doesn't work is like this:
AVI file format detected.
VIDEO: [FMP4] 624x352 24bpp 30.000 fps 1183.6 kbps (144.5 kbyte/s)
Clip info:
Software: Lavf51.10.0
==========================================================================
Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
Selected video codec: [ffodivx] vfm: ffmpeg (FFmpeg MPEG-4)
So it seems that it's an issue with MPEG4, but I see MPEG4 listed in
libavcodec, so I'm not quite sure where to go from here. Should I be
filing a bug with ffmpeg, or in trac?
Thanks
Tom
