Thanks in advance!
GeForce 9800 GTX+ driver ver. 340.108 will not play MP4 video, plays audio only.
No problems with the Nouveau driver
Fedora 31 kernel 5.4.17-200.fc31.x86_64
Running VLC I get this message: Codec `h264’ (H264 - MPEG-4 AVC (part 10)) is not supported.
Running from command prompt with more detail:
