Hey all,
Im having problems getting correct pictures from the video stream which
is opened with
av_register_all();
AVFormatContext *formatContext = NULL;
if( av_open_input_file(&formatContext, fn.toAscii(), NULL, 0, NULL)
!= 0 ) {
return false;
}
if( av_find_stream_info(formatContext) < 0 ) {
return false;
}
videoState->formatContext = formatContext;
av_dump_format(formatContext,0, fn.toAscii(), 0);
the dump returns
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f52fc01b8c0] multiple edit list entries,
a/v desync might occur, patch welcome
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'test.mp4':

that seems to be correct, however, the VideoDecoder wont get a complete
picture with avcodec_decode_video2(videoState->videoCodecContext, frame,
&frameFinished, packet);
I uploaded a sample to: http://www.asamnet.de/~winterch/test.mp4
Do you notice the same problems? If I use ffmpeg -i test.mp4 output.mp4;
output.mp4 is played correctly.
Thanks,
Christoph
