    initial v1  
    11intel-media-driver is acceleration for video decoding/encoding.  It's not applicable to most drawing that the Xorg video drivers do.  It hooks into libva which would be accessed by special code in for example ffmpeg when you are decoding video into frames ready for display.  Once you have the frame it gets drawn by whatever surface-drawing mechanism is in use.  I am eliding a lot of the detail on that because the video normally gets decoded to YUV rather than RGB and is then displayed on a separate video plane.

     3Newer hardware is being supported by oneAPI replacing libva and the oneVPL video processing library replacing the intel-media-driver, which I haven't been able to experiment with because I don't yet have hardware for it.
