Comment:
This is an avformatdecoder issue actually. The 640x480 is coming from
some fallback code in the decoder as indicated here in a "-v all" log:
2006-05-12 02:52:09.184 AFD: Stream #4, has id 0x6080 codec id MPEG1VIDEO,
type Video, bitrate 0 at 0x0x828cee0
2006-05-12 02:52:09.189 AFD: InitVideoCodec failed to align dimensions,
resetting decoder.
Right after that line is printed, AVFormatDecoder sets the info to 640x480
@ 29.97fps and 4/3 aspect ratio then calls
NuppelVideoPlayer::SetVideoParams().
You're lucky normal playback works.
From the looks of it, we should be ignoring this stream, but I'm not sure
at this time of the morning. Just wanted to update the ticket to reflect
the real issue.
