Hi,
there are several packages in the distribution which require FFMPEG (libavformat, libavcodec, etc.), one of them being chromium. The package could be created in a way that you can easily replace it with a version from rpmfusion to get to the full encoder/decoder set including H264 etc.
This is working fine with openSUSE and packages from Packman.
https://build.opensuse.org/package/show/multimedia:libs/ffmpeg-4 https://pmbs.links2linux.org/package/show/Essentials/A_tw-ffmpeg
The Packman version always has a higher release version than the one in the distribution.
I'm interested in this, as I try to package electron for Fedora. The big problem is the included ffmpeg. With openSUSE I can just use the system ffmpeg, with Fedora I have to do some source code voodoo which I really would like to avoid.
Thanks for considering!
Best regards
Andreas
