I one thread I decode H264 by
while ( av_read_frame(ic, pkt) >=0 )
{
if(pkt->stream_index==video_stream) {
AVFrame* tempFrame ;
tempFrame = avcodec_alloc_frame();
avcodec_decode_video2(video_st->codec, tempFrame, &frameFinished,
pkt);
// error
if(frameFinished) {
av_picture_copy((AVPicture*)VideoBufLast->pFrame,
(AVPicture*)tempFrame,video_st->codec->pix_fmt, video_st->codec->width,
video_st->codec->height)
etc
And the other Thread use avcodec_decode_video2 too on mgeg2
but I got decode error in the while decoding MB 109 22 in the line //error
I suspect I got the error because avcodec_decode_video2/mpeg2
How do you to COPY packets to own thread-safe sequences (each sequence
per decoding thread) ?

Gilles
