 ====== HW video decoding using VAAPI ======
+For it to work with firejail one needs to ignore ''noroot''.
+~/.config/firejail/firefox.local:
+<code>
+# Allows HW video decode
+ignore noroot
+</code>
+===== Update 2022-02-05 =====
+As of now it seems that it is working with RDD enabled (tested with Firefox 96.0.3)
+Only these two options need to be set on my AMD machine to enable it.
+<code>
+gfx.x11-egl.force-enabled	true
+media.ffmpeg.vaapi.enabled	true
+</code>
+If needed disable av1/av01 codec if there is no HW decode support (YouTube may use this with 1080p otherwise)
+This can of course affect media at other sites.
+Note that av1/av01 is NOT the same as avc1

+On newer AMD
+<code>
+while true; do cat /sys/kernel/debug/dri/0/amdgpu_pm_info | grep ^VCN; sleep 1; done
+</code>
+On Intel - check for Video engine activity
