  • ffmpeg : how to save h264 raw data as mp4 file

    15 avril 2016, par monkid

    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.

  • ffmpeg how to save decoded audio data to pcm

    21 avril 2015, par Jason

    I have succeed decode audio data from a mp4 using avcodec_decode_audio4， I want to save the decoded frames,so I tried below

    if (got_frame) {
    
  int size;
    
  uint8_t *data;
    
  int ref = 0;
    
  ret = swr_convert(swr, &data, frame->nb_samples, (const uint8_t **)frame->extended_data, frame->nb_samples);
    
  //fwrite(data, 1, frame->nb_samples, fp_audio);
    
  ref++;
    
  int szie = av_samples_get_buffer_size(NULL, 2, 1024, AV_SAMPLE_FMT_FLTP, 1);
    

    
  for (int i = 0; i < frame->linesize[0]/4; i++)
    
  {
    
    fwrite(frame->data[0] + 4*i, 1, 4, fp_audio);
    
    fwrite(frame->data[1] + 4*i, 1, 4, fp_audio);
    
    ref++;
    
  }
    

    

    

    
  av_frame_unref(frame);
    
}

    but the pcm sounds strange, I also tried directed write as follows

    fwrite(frame->data[0], 1, frame->linesize[0], fp_audio);

    or :

    fwrite(frame->data[0], 1, frame->linesize[0], fp_audio);
    
fwrite(frame->data[1], 1, frame->linesize[0], fp_audio);

    I know that the decoded pcm is AV_SAMPLE_FMT_FLTP
    any help would be appreciated
