Hi folks,
I was told that people were having trouble with Firefox/HW
acceleration/VA-API setup on Fedora so I put some info at wiki at:
https://fedoraproject.org/wiki/Firefox_Hardware_acceleration
Hope it helps.
Martin
Intel section fails to mention that accelerated video decoding on the
Iris XE (Gen12) GPUs requires intel-media-driver and won't work with
older libva-intel-driver. So we're out of luck until the sandboxing
issue is resolved and the fix is backported to Fedora Firefox builds.
As usually, please update the page.
Thanks.
Hm. I just reread the whole section again.
Martin, did you mean to use intel-media-driver (iHD_drv_video.so)
instead of the libva-intel-hybrid-driver (hybrid_drv_video.so)? Because
everything makes sense with that substitution and the sandbox bug only
mentions iHD_drv_video.so.
To be honest, I have no idea what GPUs even use
libva-intel-hybrid-driver alone. libva-intel-driver claims to support
everything up to Gen 10 GPUs and Gen11+ (Ice Lake, Tiger Lake, etc..) is
handled by the intel-media-driver. And hybrid-driver's only purpose
seems to be a VP9 decoding backend for the libva-intel-driver
(--enable-hybrid-codec).
Can someone confirm that?
