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.

    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.
