You can try to add to command line:
--allowerasing to allow removing of installed packages to resolve problems
In Fedora 39, ffmpeg-free was added to the Fedora repositories. RPMFusion already ships ffmpeg. The difference between the two is that Fedora's packages do not have license-prohibited codecs included.
RPMFusion has worked with upstream Fedora to allow libavcodecs-freeworld from the ffmpeg package to be installed over Fedora's own libavcodec-free.
The short answer here is you only need to install libavcodec-freeworld.x86_64 and libavcodec-freeworld.i686
HOWEVER if you want -full- codec support, you should instead run the Nobara Updater and click the "Install Fixups' button if it's available:
https://wiki.nobaraproject.org/Troubleshooting/update-system
The Nobara Updater has a built in Fixup script that checks for missing media codec packages. It should ask you to confirm whether or not you want to fix it by installing/correcting the missing packages.
