I think those are all I sent (have few more on termux to test).

ffmpeg versioning about making fileffmpeg and few other files compile/work
with both ffmpeg 4.4 and 5.0/5.1 (hopefully). This is roughly how Einar
makes cin-cve compile against wide range of ffmpeg libs...

it worked on arm 32 and should be fairly generic, but new major ffmpeg
version bump most likely will need additional research....
