[gavio-dot]

Adding an intro to a video (both mp4 format but different resolutions) always throws

Peertube was updated to 7.0.1 from 6.3.2 and Ubuntu upgraded to 22 LTS to get an above recommanded version of FFMPEG but still got the same error as before.
In another older installation upgraded to 6.3.3 from an older 5.something and with ubuntu 20 LTS the problem is not happening

• PeerTube Version: 7.0.1
  • NodeJS version: v20.18.2
  • Ffmpeg version: 4.4.2-0ubuntu0.22.04.1

UPDATE:
the issue seems to be linked to the configuration setting "Split audio and video streams" that is enabled in the server with the error. If I disable it I get no ffmpeg error. Should I update ffmpeg to a more recent version to fix the problem? Any suggested version?

Thanks! It's a peertube bug, that should be fixed by 319932c
