Bug 274591: multimedia/ffmpeg package lacks intel quicksync / qsv / hardware
encoding support
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=274591



--- Description ---
ffmpeg installed with pkg command lacks support for intel qsv / quick sync /
hardware encoding

This is widely used for programs like handbrake, jellyfin, emby, plex, shotcut,
kdenlive, and other video editors.

I was able to work around this by building ffmpeg from source with the
following configuration options then running gmake -j4

./configure --enable-libvpl --cc=clang

Compare output from system ffmpeg and rebuilt ffmpeg below
