You already merged most of the FFmpeg cleanup to our FFmpeg repository.
I'll create a new PR (or reuse https://github.com/MythTV/FFmpeg/pull/5
to add the few not yet merged changes that are in FFmpeg cleanup.

Since I already separated the mythtv changes when creating the already
merged commits for the FFmpeg repository, I don't see any harm in having
commits that change both at the same time.

* da498f9f05 2022/06/12 ulmus-scott : remove FFmpeg addition
I could separate this, but I don't see the point since the change is
already in the FFmpeg repository.
* 64a3c60ee5 2022/06/12 ulmus-scott : replace ff_codec_id_string()
This requires 1c346ec1ac 2022/06/12 ulmus-scott : add MPEG2VBI and
DVB_VBI to codec_desc.c (ffmpeg only change) for the MythTV changes to
work properly in all cases. Again, I could separate this, but I don't
see the point since the change is already in the FFmpeg repository.
The only other mixed commit is beba76345e 2022/06/12 Scott Theisen :
mpegts-mythtv.c: export disposition from ISO_639_LANGUAGE_DESCRIPTOR. I
could split this and have the FFmpeg change first, but it makes more
sense to me to keep them as one atomic commit since the MythTV change
requires the FFmpeg one to work properly.
