[Ffmpeg-devel] h264.c patch, always decoding extradata when on non avc stream

Hello,
I was decoding a h.264 stream initiated with RTSP and found out that
extradata is always being processed.
The check is currently:
if(!h->is_avc && s->avctx->extradata_size && s->picture_number==0){
//process extra data
The problem was s->picture_number never being incremented.
So I added s->picture_number++ when outputting a frame.
Also for the sake of performance I re-ordered the if(...) line so the
s->picture_number==0 is checked first since it is the most likely check that
will fail and it will jump right away to the next block.
Thanks,
Francois Oligny-Lemieux
