[FFmpeg-devel] [PATCH] improve H.263 probe

[Reimar Döffinger]

Hello,
related to issue2363.
If there is only one single frame raw MPEG-2 and H.263 detection conflict
and result in a negative value.
Below patch fixes the given sample, however I guess it might result in
single-frame H.263 files not being detected correctly...
Opinions/ideas?
