[MPlayer-dev-eng] Ugly H.263 display bug

[Shan]

Hi,

I just noticed a really ugly bug which affects VLC as well as mplayer 
when an AVI or MOV containing a H.263 stream with no aspect set is 
displayed on screen and I'm at a loss over how best to fix it without 
possibly screwing the RTP demuxer display size up!

What happens is both parse the correct display size from the file 
header, but during the video setup both VLC and mplayer set the display 
size that is passed from ffmpeg's H.263 codec.  Which ends up being a 
default size of 352x288 so you can imagine that a video that's really 
160x120 or 320x240 would end up having black borders added to the right 
and bottom.

Of course ffplay, JMF, quicktime and other players don't have a problem 
as they take the header value as the only indication of the display 
size.
