[Ffmpeg-devel] Demuxing still pictures in dvd's II

[Jan-Willem Mulder]

you might want to look at ffmpeg.rar in
'cvs\XBMC\docs\sources\dvdplayer\ffmpeg' it contains the entire
modified ffmpeg source code that we use (XMBC) for our dvdplayer. That hack
suggested in 'http://comments.gmane.org/gmane.comp.video.ffmpeg.devel/24165'
is still in that source and is working ok for us (although it is not ok for
a ffmpeg patch I think :) ).  It is the only solution as far as I know.
The problem is that you cannot detect if a video stream has ended from
ffmpeg and neither libdvdnav detects such stills. calling
avcodec_decode_video twice will output the 'incomplete' frame as you already
have noticed (I believe it is actualy just a flush of the current frame?)
but it has no use, since you cannot detect the end of a stream. Also, when
you want to switch to libmpeg2 you have the same problem again. Applying
that posted hack, you will not need to call avcodec_decode_video. It will
just work.
