Recently I investigate this issue further. The profile of this h264 video is main, not baseline. Using avcodec_decode_video
with old avcodec library can parse this file, but avcodec_decode_video2 can't. I have read the following thread, but it can't solve my question.<BR> <BR><a href="http://ffmpeg.arrozcru.org/forum/viewtopic.php?f=8&t=1512">http://ffmpeg.arrozcru.org/forum/viewtopic.php?f=8&t=1512</a><br> <BR>Can you please give me a hint? <br>Thank you a lot !
