[timothymowens]

The Intel® Media SDK (libmfx) project has been discontinued due to some security issues. Intel is no longer maintaining this project.

They instead created the Intel® Video Processing Library (libvpl) to replace Media SDK library (libmfx):

According to documentation provided by Intel, replacing libmfx with libvpl in FFmpeg is a very simple switch:

How to enable VPL

The switch to VPL from Media SDK in FFMPEG, is simple. Just substitute ‘--enable-libvpl’ instead of ‘--enable-libmfx’ in the configure stage of FFMPEG compilation. Both options enable compilation of Intel® Quick Sync Video (*_qsv) codecs, which can be used without change from the FFMPEG command line or in applications.

The git repo for libvpl is here:
