Can I just follow your original list?
Plus a couple of steps of mine.
Summary/order of operations:
0a. Apply 2 commits to MythTV/FFmpeg master that were made in
* 6a79086179 2022/02/24 Martin Storsjö : configure: arm: Don't add
-march= to the compiler if no preference was passed

2a. test? I'm not sure how.
3. copy FFmpeg/master into mythtv (depends on all of 1 and 2)
4. Test changes to FFmpeg (should have already tested good)
5*. https://github.com/MythTV/mythtv/pull/575 and
https://github.com/MythTV/FFmpeg/pull/5 av_disposition should be added
here to match the histories of FFmpeg and mythtv (otherwise it could be
part of 1)
6. apply the harmonize commits to FFmpeg
7. copy the harmonized FFmpeg to mythtv
8. Test new mpegts-mythtv, especially with DSMCC/MHEG, which I couldn't
9. Apply FFmpeg commits until version 5.0
10. copy FFmpeg 5.0 into mythtv
11. test FFmpeg 5.0
