intel-media-23.4.3

Introduction to intel-media

The intel-media package provides a VA API driver for Intel GPUs that are provided with Broadwell CPUs and higher. This includes support for a variety of codecs.

This package is known to build and work properly using an LFS 12.1 platform.

Installation of intel-media

[Note]

Note

This package takes a long time to build because it compiles code specific to each individual generation of Intel GPUs and for a variety of media codecs.

If you know the model of your Intel GPU, you can pass the -D{GEN{8,9,11,12},MTL,ARL}=OFF option to the cmake command but leaving the option for your GPU out. Note that the “GEN” number here is the generation of the GPU, not the CPU. For example, with an Intel Core i7-1065G7 CPU shipping a 11th-generation Intel GPU, the -D{GEN{8,9,12},MTL,ARL}=OFF option can be used so the code specific to the other generations of Intel GPUs won't be built.

To determine the model of the Intel GPU, install pciutils-3.10.0 and run lspci -nn | grep -Ei 'VGA|DISPLAY' first. It will output some information about the GPU. If the output contains Meteor Lake, the GPU model is MTL. Otherwise, follow https://dgpu-docs.intel.com/devices/hardware-table.html to find the entry for your GPU and the model of the GPU should be in the “Architecture” column. The Xe and XeHPG architectures are covered by the GEN12 model.

Install intel-media by running the following commands: 

mkdir build &&
cd    build &&

cmake -DCMAKE_INSTALL_PREFIX=$XORG_PREFIX \
      -DINSTALL_DRIVER_SYSCONF=OFF        \
      -DBUILD_TYPE=Release                \
      -G Ninja                            \
      -Wno-dev ..                   &&
ninja

This package does not come with a test suite.

Now, as the root user: 

ninja install
