• How to replace the video track in a video file with a still image ?

  22 février 2021, par cornerstore

  I am trying to use ffmpeg to replace the video track in a video file with a still image. I tried some commands I got from other questions such as the one here

  


  ffmpeg -i x.png -i orig.mp4 final.mp4

  


  ffmpeg -r 1/5 -i x.png -r 30 -i orig.mp4 final.mp4

  


  But these didn't work. I'm not sure which of these arguments are required or not. The output should be accepted by YouTube as a valid video - I was able to simply remove the video track, but apparently they don't let you upload a video without a video track.

  


• Does anybody know how to concat on ffmpeg and python ? [closed]

  22 décembre 2023, par Jonas Harker

  I created a code on Python that supposedly concatenates two videos using Python to run an ffmpeg command through subprocess.
I get this error message :

  I hoped they would concat, but they did not.
