Yup, that's exactly one of the reasons why other projects like GStreamer
have gained that much popularity. It might not have happened when
ffmpeg would have been more open and extensible in the first place.

I had similar things in mind already. The graphicsubs2text filter kind of uses
AI already, but it was only possible because it does it through a standard 
lib (tesseract). But as soon as it comes to anything which requires using 
an API that is vendor-specific, that's something which nobody will want 
to have in ffmpeg, and it might also change rapidly in a way that it's already
outdated when its containing ffmpeg version gets packaged by a distro.

Totally agree. Saying that we have no solution for these things is a path 
to becoming Irrelevant in the future.


What do you people think about the feasibility of a compile-time plugin
mechanism?
Given that on most platforms (except Windows), you can't easily mix 
binaries from different origins (i.e. built differently), it would be much
easier when plugin binaries could be compiled as part of building ffmpeg
rather than having to set up and maintain separate builds for each plugin.
