 Problem: package ffmpeg-libs-6.0-6.fc38.x86_64 conflicts with libavcodec-free provided by libavcodec-free-6.0-4.fc38.x86_64
  - package ffmpeg-6.0-6.fc38.x86_64 requires ffmpeg-libs(x86-64) = 6.0-6.fc38, but none of the providers can be installed
  - conflicting requests

It seems like the problem is that libavcodec-free and libavfilter-free etc. has been included in the 38 base image when they were not in the 37 base image. This is causing all kinds of problems from rpm firefox not being able to play h264 videos, to ffmpegthumbnailer not generating thumbnails (upstream issue), and failing upgrades to 38. And people are resorting to hacky solutions. Also it seems like this problem already existed on Kinoite 37.

To Reproduce Please describe the steps needed to reproduce the bug:

1. Try to install ffmpeg-libs on Fedora Silverblue 38 or Kinoite 37.

Expected behavior ffmpeg-libs successfully installed

Thanks for the hacky solution: https://discussion.fedoraproject.org/t/unable-to-install-ffmpeg-libs-on-fedora-38-silverblue-beta/79632/8

hi @travier , could you elaborate on why this is now "closed as completed" -- is the posted workaround now the official one? Thanks!

[travier]

ffmpeg-libs is a package from RPM Fusion and is thus not part of Silverblue. There is no "official" way to modify the base image. As far as I understand, there is nothing for us (Silverblue) to do here.

Probably worth trying ffmpeg-free too, which is part of Fedora now

Thank you for your response! I'm not asking for ffmpeg-libs to be added to the base image, but to revert to when libavcodec-free libavfilter-free libavformat-free libavutil-free libpostproc-free libswresample-free libswscale-free are not included. I feel like it's against Silverblue's ethos of avoiding system entropy if users are forced to rpm-ostree override remove 7 packages to get basic functionality.

I need ffmpegthumbnailer for Nautilus (which should be part of the base image), which depends on ffmpeg-libs from RPMFusion. Video thumbnails are quite useful.

As far as I know, we're including those packages in the image to increase the number of file format that we support by default. If you want to replace those versions by the one from RPM Fusion to get even more codec support then you have to remove them as done in the command above.

OK, so this is not the same request. If you want ffmpegthumbnailer to be added to Silverblue then:

• it needs to be packaged in Fedora (https://src.fedoraproject.org/rpms/ffmpegthumbnailer).
• it needs to depend on the version of ffmpeg packaged in Fedora.

Please make another issue to track that.

This is the command for f40

rpm-ostree override remove \
  ffmpeg-free \
  libavcodec-free \
  libavdevice-free \
  libavfilter-free \
  libavformat-free \
  libavutil-free \
  libpostproc-free \

  --install ffmpeg
