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. http://ffmpeg.arrozcru.org/forum/viewtopic.php?f=8&t=1512 Can you please give me a hint? Thank you a lot !

hi all, I write a H264 decode program referring to the following link: http://www.inb.uni-luebeck.de/~boehme/using_libavcodec.html Because I use the FFmpeg 0.8.6, I change this sample from avcodec_decode_video to avcodec_decode_video2, just like the following codes: AVPacket g_avpkt; bool GetNextFrame(AVFormatContext *pFormatCtx, AVCodecContext *pCodecCtx, int videoStream, AVFrame *pFrame) { ......... if(av_read_frame(pFormatCtx, &g_avpkt)<0) bytesDecoded=avcodec_decode_video2(pCodecCtx, pFrame, &frameFinished, &g_avpkt); ......... Firstly av_read_frame read some data from an h264 file(D1), but avcodec_decode_video2 always return with -1. I have tried these code with h264 file(safe), it is ok. How to use avcodec_decode_video2 to decode h264 files correctly?
