[XviD-devel] Different length reading sprite-trajectory

[Christoph Lampert]

Hi,

there is a mismatch between FFmpeg and XviD when decoding length of
sprite_trajectory.

>From the bitstream 

fe ef d2 c3

XviD reads (and writes):  length=9 x=-272  
in mbcoding.c (bs_get_spritetrajectory())

whereas ffmpeg reads   :  length=10 x=959   (using get_vlc())
in h263.c (mpeg4_decode_sprite_trajectory())

Can some guru check which is correct? The standard says
just that it's unsigned integer, most significant bit first.
