Thanks. I've read that tonight. Earlier just for the fun of it I
installed the Radeon drivers on winsows10. I installed handbrake and
had it transcode the same video I experimented with earlier. When I
chose the codec, I found H.264 (AMD_VCE). There was also an H.265
AMD_VCE option but I didn't try it. Handbrake in Windows was
transcoding the video at around 100 to 110 fps and only using 1% of the
CPU. I may not use hardware acceleration for encoding often, but I'd
like to have it available. It doesn't matter to me if I use the open
source drivers or the proprietary ones. I can't help but wonder why it
won't work in Linux.
