[Libav-user] avcodec_decode_video2 decode h264 file return -1

[曲亚东]

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 !

Subject: [Libav-user] avcodec_decode_video2 decode h264 file return -1















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? Thanks a lot.
