Usual incompetent questions of mine:
Can I install all the patches together with "git am"?
I did exactly this with patches from massive-update folder on x86 Slackware - seems to work fine .... But usually patches named 'library.patch*' go into thirdparty/src folder, then you can git add them and git commit as you wish ....
Should I rename
the ones that have the same number? Should the patch ending with
"*.patch0" be renamed without 0?
Well, I started from patch0 because it was patch essential to building ffmpeg on termux, yet you can rename patches in same manner as they were for 4.4 - just lower patch number by 1 (one).
old ffmpeg.patch3 added some seeking behaviour not present in current ffmpeg, but file/function it tries to patch moved ...somewhere, not sure where. So for now I not included incomplete patch - I wonder if it still needed (patch affects dv and matroska containers, and avi too)
