  • docker service create : How to deal with custom or unknown parameter needed by linuxserver/ffmpeg image ?

    24 mai 2022, par Mike

    I am new to docker and docker swarm and started dockerizing several services and am trying to get them running as docker swarm services. I ran into a road block with the linuxserver/ffmpeg image :

    


      

    1. it uses a —device parameter which is not implemented in create service

      2. 


    2. it expects several custom parameters to pass them to the ffmpeg encoder

      3. 


    


    From my research up to now I assume that passing parameters is not implemented in docker create service, but maybe you can think of a workaround ? (unfortunately the image does not process environment variables, or at least they are not documented)

    


    This is how I start dockerized ffmpeg (working fine in standalone mode) :

    


    docker run -d /
    
—network="host" /
    
—device=/dev/video0 :/dev/video0 / ### error : unknow flag
    
—name ffmpeg_streamer /
    
—restart always -it /
    
-v $(pwd)/video :/video /
    
linuxserver/ffmpeg / ### custom parameters below here
    
-stream_loop /
    
-1 -re -nostdin /
    
-i "/video/test.avi" /
    
-f pulse /
    
-vcodec libx264 /
    
-preset:v veryfast /
    
-b:v 400k /

  • ffmpeg and Youtube upload - can't merge existing audio track with external one

    9 avril 2012, par Aleksy Goroszko

    I am realizing campaign, where idea is that users are creating TV ad. The process looks as following :

    • User watches ad (youtube video)
    • User selects video (mp4 file played in Flash Player)
    • User records his own voice using webcam/mic for the selected video
    • User's voice is uploaded to server
    • User's voice is merged with selected video (video+music) and saved as mp4 file
    • User's video is uploaded to youtube

    When realizing audio-video merging I found some suprises :

    When I was using command

    ffmpeg -i sourceVideoFile.mp4 -i sourceAudioFile.mp3 -acodec copy -vcodec copy outputFile.mp4 - video's music was replaced by user's voice.

    So I used option -newaudio :

    ffmpeg -i sourceVideoFile.mp4 -i sourceAudioFile.mp3 -acodec copy -vcodec copy outputFile.mp4 -newaudio - I can hear that output video has both music and user's voice. So - that's what I wanted to reach. But...

    The surprize is that if I upload this video to Youtube, after it's processing I can watch it and hear only music. User's voice disappears !

    So, how to keep both voice and music ?

    Any idea, gurus ? :)
