* ffmpeg4-5-6: Fix /usr/local/bin symlink

* service.mk: Add ability to generate json for VIDEODRIVER access

Having a preset conf/resource file makes it that no other
parameters can be set in the resulting file.  This removes the
need of the static file for accessing video-driver by generating
it directly within the normal jq call.

* ffmpeg4-5-6: Misc fixes including symlinks and proper rpath for v4

* github-action: Fix mgmnt of ffmpeg,ffmpeg5,ffmpeg6 dependent spk

* github-action: ffmpeg package is actually spk/ffmpeg4

* ffmpeg6: Remove invalid older jellyfin patch

* ffmpeg4: Update howto pertaining to jellyfin patches

* chromaprint+comskip+tvh: Fix ffmpeg dependency version

* tvheadend: Update changelog for updated openssl version
