Hi, in about:config in Codec Support Information, in the column Hardware Decoding - I see Unsupported for all. Why? My CPU is AMD 7950x.

You need to use hwaccel USE flag:
| Code: | % equery u www-client/firefox
hwaccel : Force-enable hardware-accelerated rendering (Mozilla bug 594876) |
Gentoo Wiki - Firefox#Hardware_acceleration should have interesting info too if it's still not working. |

I've wasted several hours - days even - over the years trying to get a handle on this. AFAIR the hwaccel USE flag only overrides gentoo's initial firefox default runtime configuration (I think media.hardware-video-decoding.force-enabled), but it has absolutely no effect on the code compiled. IIUC it's there for users who don't trust themselves to edit firefox "about:config". Setting it doesn't necessarily mean you will get HW acceleration; that depends on whether firefox thinks it's possible on what it considers to be your hardware.
There are many threads on lots of mailing lists for many distros discussing how to get HW acceleration; most of them end up saying the same thing about a few settings in about:config, though I forget what they are. Whether they take effect at any particular point in time depends on the mages lurking inside the firefox release de jour. Kernel configuration, and the availability of VA-API and/or VDPAU depending on graphics cards. (While checking, I note according to the Arch wiki there is now a new acceleration API, AMF for AMD kit, and one for NVIDIA kit, NVDEC. More to play with )

I think that's the oddest functionality of a USE flag I've perceived. | Quote: | | While disabling the hwaccel USE flag will get rid of the required about:config options, these can be enabled manually regardless of the USE flag status. To disable hardware acceleration, edit about:config with media.hardware-video-decoding.enabled set to false. |
(from the above referenced wiki link)

| Code: | | cat /var/db/repos/gentoo/www-client/firefox/files/gentoo-hwaccel-prefs.js |
has:
| Code: | /* Force hardware accelerated rendering due to USE=hwaccel */
pref("layers.acceleration.force-enabled", true);
pref("webgl.force-enabled", true); |
I enabled it, restarted Firefox - still the same - Hardware Encoding in Unsupported for every codec name, in about:support#media.
From the wiki:
| Quote: | | Make sure vaapi works outside Firefox first with vainfo program |
Looks like not working for me?
| Code: |
vainfo
Trying display: x11
libva info: VA-API version 1.21.0
libva info: Trying to open /usr/lib64/va/drivers/radeonsi_drv_video.so

Per PFL, radeonsi_drv_video.so is provided by media-libs/mesa. It has a "vaapi" USE flag. It might be worth checking to make sure it doesn't have any other related flags.

It does install vaapitest binary which is required to get hwaccel to work. There was a time when I thought about always enabling hwaccel because as you said, it's a pretty expensive use flag to toggle for small gains, but there were people whose browser crashed with +hwaccel so it better stay as a use flag for now. |

| Something I've thought about a few times over the years is splitting the config customisation into a separate package with USE so we can easily toggle them without an expensive FF rebuild. |

Thanks, I enabled global USE vaapi and now in about:support I see Hardware Decoding is supported for H264.
Previously I disabled vaapi globally in order to have ffmpeg 6, not 4 - it was a dependency for VLC. |

Hmm but on another machine I also set global vaapi, rebuilt the system, in about:support#media I see Hardware Decoding for vp9, av1, but not for H264, all about:config flags from this page are enabled, what to do?

Per Juippisi's comment regarding troubleshooting, if nothing else helps, maybe the logging will provide more info.
