        The <application>intel-media-driver</application> 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.

      <note>
        <para>
          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.
        </para>

        <!-- This reduce the size of iHD_drv_video.so from 319M to 157M
             for me.  -->
        <para>
          If you know the model of your Intel GPU, you can pass the
          <option>-D{GEN{8,9,10,11,12},MTL}=OFF</option> option to the
          <command>cmake</command> command but leaving the option for your
          GPU out.  Note that the <quote>GEN</quote> 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
          <option>-D{GEN{8,9,10,12},MTL}=OFF</option> option can be used
          so the code specific to the other generations of Intel GPUs won't
          be built.
