Notes

Questions and discussions:


What to do about native backends on 6.8.

  • Suggestion: make them opt-in
  • KDE point of view: android is causing the most pain. FFmpeg is painful to cross compile to android. For simple camera access the native backend is better. Think about simple use cases where codecs aren't needed


It is possible to build ffmpeg with a super minimal configuration to have it in a small size.

How about reduce the support for native backend to the minimal basic use cases? -> Seems to be an acceptable approach
