• ffmpeg codec for rtmp for Youtube fails for GetDisplayMedia

  19 janvier 2023, par Kubi

  I am trying to encode via a nodejs app and encode and output the incoming stream to RTMP and stream it on YouTube and these arguments below are working fine with getUserMedia API. However, I don't get any data when I try getDisplay media. Should I change any of these parameters ? I am a total beginner in ffmpeg.

  


  const youtubeArgs= [
    '-i', '-', '-v', 'error',
    '-c:v',
    'libx264',
    '-preset',
    'veryfast',
    '-tune',
    'zerolatency',
    '-g:v',
    '60',

    '-c:a',
    'aac',
    '-strict',
    '-2',
    '-ar',
    '44100',
    '-b:a',
    '64k',

    '-y',

    '-use_wallclock_as_timestamps',
    '1',
    '-async',
    '1',

    '-f',
    'flv',
];


  


• FFmpeg youtube stream get corrupted until restart

  19 février 2023, par unpwn

  I am streaming images from python to youtube using ffmpeg.
It's working fine with just one problem.
Sometimes the stream get somehow corrupted an the stream looks like this :

  


  Corrupted stream image

  


  Or you can see for yourself in the stream itself : https://www.youtube.com/watch?v=PG6NLtr0jjM (Scroll back to the beginning)

  


  Then I have to restart ffmpeg and its working fine. Sometimes an error occurs regarding the network and I have to automatically restart the stream. Then there is the possibility it is corrupted again.

  


  The parameters for ffmpeg are the following :

  


  cmd_out = ['ffmpeg',
       '-re',
       '-f', 'concat',
       '-i', os.path.join(BASE_DIR, 'music', 'music.txt').replace('\\', '/'),           
       '-r', '1',
       '-f', 'image2pipe',
       '-vcodec', 'png',
       '-r', '1',
       '-i', '-',
       '-c:v', 'libx264',
       '-c:a', 'copy',
       '-g', '4',
       '-f', 'flv',
       'rtmp://a.rtmp.youtube.com/live2/{}'.format(stream_key)]  


  


  I never had that problem testing it on windows. It just appears when I use my linux server.

  


  I am using ffmpeg version 3.2.18-0+deb9u1 and the generated images are fine, when I save them to a normal file.

  


  Does someone know how to fix it ? Or where the problem is comming from ?

  Solution : An old ffmpeg version was available while using docker. I solved the problem by using a static build from https://www.johnvansickle.com/ffmpeg/

  


  I used this to use it in docker :

  


  WORKDIR /app
ADD ./ffmpeg /app
RUN mv ffmpeg /usr/local/ffmpeg
RUN chmod +x /usr/local/ffmpeg


  


  Until now the error seems to be solved.
