I encode h264 data by libavcodec.
ex.
while (1) {
...
avcodec_encode_video(pEnc->pCtx, OutBuf, ENC_OUTSIZE, pEnc->pYUVFrame);
...
}
If I directly save OutBuf data as a .264 file, it can`t be play by player. Now I want to save OutBuf
as a mp4 file. Anyone know how to do this by ffmpeg lib? thanks.

You use avformat_write_header, av_interleaved_write_frame, avformat_write_trailer and friends.
Their usage is shown in the muxing example of FFmpeg.
