• Can you stream multiple video clips to youtube or twitch with a separate audio track with a different length than the video clips with FFMPEG ?

  8 juin 2020, par Fight Fire With Fire

  What I'd like to do is stream a set of video clips to youtube or twitch using FFMPEG. Right now i loop thru the videos file names in a list called DIRECTORY. video[0] is the file name and send to stream_url with the audio for the video attached.

  



  What i would love to figure out, is there a way I could mux in a single audio track streaming to youtube/twitch but switch the video clips out live. Here is the code I am working with right now :

  



  
     for video in directory:
            command = [
            "ffmpeg" , "-re" , "-i" , video[0] ,
            "-vcodec" , "libx264", "-pix_fmt", "yuv420p",
            "-preset" , "medium" , "-r" , "30" , "-g" , "48" , "-b:v" , "2500k" ,
            "-acodec" , "libmp3lame" , "-ar" , "44100", "-threads" , "6" ,
            "-q:a" , "3" , "-b:a" , "712000" ,"-bufsize", "512k" , "-f" ,
            "flv" , STREAM_URL,
        ]
             subprocess.run(command)

• 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.
