[MPlayer-dev-eng] ffodivx crash with qt6's .mp4 files - divx5linux works

[Arpi]

Hi,

Michael, could yo uplease look at:
mphq/MPlayer/samples/MPEG-4/fridayafternext_http.mp4
(it's a sample mpeg-4 file of Quicktime Player 6.0)

i've just fixed an idiot bug in demuxer layer, causing crash on this file
before, now the demuxer works fine, but i get crash with ffodivx codec.
decoding with divx5linux (-vc odivx, after adding fourcc mp4v in
codecs.conf) works fine.
