It includes code over which various people claim to have patents
and RedHat don't want to get sued by the owners of those patents.
This is a common problem with audio and video codecs which often
involve algorithms which are subject to patent claims.

prevents fedora from including it?

Blender in Fedora repository is built with ffpmeg support disabled

Make sure to keep that repo disabled to avoid conflict with rpmfusion.

Thanks Luya,
I have all ffmpeg and gstreamer codecs installed. However, I think
blender was installed by OpenShot before I actually installed
ffmpeg and gstreamer codecs.
So, it might be the reason why it does not play videos or music.
But, reinstalling blender didn't help. Never had this issue before.

Hello Mehda,
Blender requires ffmpeg which cannot be legally included in
Fedora
repository to effectively use multimedia due to US patents
law. One of
best approach is either get ffmpeg without the offending
codecs or
enable an alternative like gstreamer which is beyond the scope of
packaging process.
