• Pros and cons of installing ffmpeg into the caller's docker container vs. separate container [closed]

  8 mai 2022, par Irina Rapoport

  I have a dockerized app that spawns ffmpeg in a child process. It then communicates with it via standard input/output. The app runs under k3d.

  


  I could install ffmpeg in the parent's Dockerfile, by doing

  


  RUN apt-get install -y ffmpeg


  


  Or I can run it in a container of its own. What are the pros and cons of each approach ?

  


  Container start-up cost, while small, may become an issue, because it's started often.

  


• ffmpeg multiple time depends on availability of CPUs [closed]

  21 novembre 2020, par xserverx

  I have about 400 Video files I would like to convert them.

  


  I have this code :

  


  for /r %i in (*.mp4) do ffmpeg -y -i "C:\Users\mosp\Desktop\image.jpg" -i "%i" -stream_loop -1 -i "C:\Users\mosp\Desktop\240.mov" -filter_complex "concat[c],[c][2:0]overlay=shortest=1"  -ar 44100 "%i.mkv"


  


  But this code run the command after I have the previous one finished.
In the current server, I have 64 vCPUs, so I need to run FFmpeg for the first 64 videos at once so each vCPU should take one task.
Once a task finished I should have the next FFmpeg commands started depends on the available vCPUs etc.
