• 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.

  


• Pycord Music Bot : AttributeError : 'FFmpegAudio' object has no attribute '_process'

  5 juin 2022, par Steven Mao

  I've made a discord Cog that should be able to queue up and play music, but I'm getting an error from FFmpeg when I actually try to play the URL. I have found an identical question on StackOverflow, but this user's problem was a random typo. The inputs should all be correct, so I am not sure if the problem is my code or my package.

  


  What have I done wrong ?
