  • Why my log printed many times using c api of ffmpeg decoder v2.8 which should be printed once when the callback return value is 1

    30 juillet 2019, par user10960024

    Documentation said when the callback functor interrupt_cb return 1, the blocking operation will be aborted. However, my program echo the log many times which should be printed only once log before it quit. How can I fix it ?

    AVFormatContext* formatContext = libffmpeg::avformat_alloc_context();
    
formatContext->interrupt_callback.callback = interrupt_cb;
    
formatContext->interrupt_callback.opaque = formatContext;
    

    
int interrupt_cb(void *ctx)
    
{
    
    if (...)
    
    {
    
        LOG(WARNING) << "decoder timeout!"; // it print many times
    
        return 1;
    
    }
    
    return 0;
    
}

    I expect the output would be printed only once.

  • combine video and audio .webm files based on wallclock times

    30 juillet 2021, par Zach

    I have a node server recording webrtc streams as separate video/audio files via ffmpeg.
I'm running ffmpeg via node's

    


    child_process.spawn('ffmpeg', commandArgs);


    


    Unfortunately, when I try to combine video and audio files later on, I don't know when ffmpeg created the first frame of each file, resulting in out of sync faces and voices :(

    


    Here's my command line args for piping the stream into ffmpeg

    


     '-loglevel',
  'debug',
  '-reorder_queue_size',
  '0',
  '-protocol_whitelist',
  'pipe,udp,rtp',
  '-fflags',
  '+genpts',
  '-f',
  'sdp',
  '-i',
  'pipe:0',
  '-map',
  '0:v:0',
  '-c:v',
  'copy',
  '-use_wallclock_as_timestamps',
  '1',
  '-timestamps',
  'mono2abs',
  '-flags',
  '+global_header',
  './recordings/video_1627600996166.webm'


    


    I was thinking that it might be possible to set the timestamps of packets to the linux's clock times, and tried a bunch of flags (-timestamps abs, -timestamps mono2abs, -use_wallclock_as_timestamps 1) but nothing seemed to change the result in the file. (I also have tried moving the time commands all around).

    


    packet|codec_type=video|stream_index=0|pts=0|pts_time=0.000000|dts=0|dts_time=0.000000|duration=N/A|duration_time=N/A|convergence_duration=N/A|convergence_duration_time=N/A|size=14568|pos=552|flags=K_


    


    Time always starts at 0.

    


    Any help figuring out how to get accurate times from my recorded audio/video .webm files so I can accurately combine them would be amazing.

    


    Thanks so much :)
