Patch widgets/gtk/GfxInfo.cpp file for www/firefox port to if-zero the unconditional blocklist for ATI/AMD/Radeon hardware at around line 1113 for DeviceFamily::AtiAll and the FEATURE_HARDWARE_VIDEO_DECODING. Part of 'META' PR: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=278150 Regards, vermaden
This patch is probably the wrong way. The correct way to enable video decoding using VA-API for both Intel and AMD is to toggle media.ffmpeg.vaapi.enabled to true in about:config so I think that the correct patch would be to switch that by default for us. That would mean testing on nvidia hardware (which doesn't have VA-API) just to check if this causes problems or not.
