Intel Hardware Decode

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

Fedora ships libva-intel-media-driver, which is its own build of Intel's iHD driver with the restricted codecs removed. RPM Fusion's nonfree repository ships the complete intel-media-driver, which installs to /usr/lib64/dri-nonfree and therefore wins the search order:

sudo dnf install intel-media-driver

For older Intel graphics (roughly pre-Broadwell, the i965 generation), the driver is a different one and lives in RPM Fusion free:

sudo dnf install libva-intel-driver

If vainfo picks the wrong driver on a machine that could use either, force it:

LIBVA_DRIVER_NAME=iHD vainfo
