Details

When starting Aegisub 3.2.2-40 when ffms2 2.40-1 is installed, the program exits with message

"aegisub-3.2: symbol lookup error: aegisub-3.2: undefined symbol: FFMS_DoIndexing"

Everything works fine (at least a functional program) with ffms2 2.23.1-4.
This task depends upon

Upstream is changing the API/ABI [1] with no soname bump [2].

[2] https://github.com/FFMS/ffms2/issues/359#issuecomment-683291246
Edit:
aegisub is not compatible with the new version without patching. Seems to need more than just [3].

[3] https://github.com/Aegisub/Aegisub/commit/1aa9215e7fc360de05da9b7ec2cd68f1940af8b2

Also needed 7a6da26be6a830f4e1255091952cc0a1326a4520 and ebc76c8a1168d16054a1f7c6d3920c0fa9c9d717 (which does not apply cleanly edited version attached) plus changing -Wno-c++11-narrowing to -Wno-narrowing.
With those changes the package builds.

Thanks for patching aegisub; although I don't understand everything that the patches do (though I agree X11 is wonderful), aegisub seems to work again. Only one warning shows up:

Warning: Mismatch between the program and library build versions detected.
The library used 3.0 (wchar_t,compiler with C++ ABI 1013,wx containers,compatible with 2.8),
and your program used 3.0 (wchar_t,compiler with C++ ABI 1014,wx containers,compatible with 2.8).
