AMD Hardware Decode

What hardware video acceleration needs on AMD graphics. Check vainfo there first.

sudo dnf install mesa-va-drivers-freeworld

Since Fedora no longer ships mesa-va-drivers, this is a plain install rather than a swap; the freeworld package provides the name. It covers radeonsi and r600. Note that AV1 and VP9 decode on AMD work on stock Fedora — it is H.264, HEVC and VC-1 that this package restores.

Vulkan Video decode is a separate, newer path. RPM Fusion documents it as a swap:

sudo dnf swap mesa-vulkan-drivers mesa-vulkan-drivers-freeworld

Only worth doing if you have an application that specifically uses Vulkan Video; most still use VA-API.
