    4444  This is a mostly-free [#i965 (but see below)] driver for the libva / VAAPI instructure.  Most Linux distributions package it.
    4545VAAPI with iHD driver
    46   The newer VAAPI driver variant from Intel which is also used by libmfx on Linux. There's a completely free distribution and one that includes closed-source kernels.
     46  The newer VAAPI driver variant from Intel which is also used by libmfx and libvpl on Linux. There's a completely free distribution and one that includes closed-source kernels.
     47libvpl on Linux / Windows
     48  This is a library from Intel which can be installed as part of Intel oneAPI Video Processing Library (OneVPL). OneVPL is the successors of MSDK and will support more encode and decode cases. spec: [https://spec.oneapi.io/versions/latest/elements/oneVPL/source/index.html]

     111=== libvpl ===
     112The library is the successors of libmfx. It will support Intel's platform >= Alder Lake and will add new features. libvpl.so is compatible with MSDK's runtime (libmfxhw64.so) and libmfx.so also has forward compatibility with oneVPL's runtime (libmfx-gen.so).
