Sorry, my English is not very good !

  


  I want ffmpeg to use GPU hardware acceleration. The above is my code, but it has been executing incorrectly. This problem has plagued me for several days. I hope you can help me, thank you !

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

  


  


  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 /
  
-f flv rtmp ://localhost:1935/live/streamkey

  


  Many thanks for looking into this !
