I'm trying to make Chromium be more compatible with more versions of
ffmpeg:
<https://groups.google.com/a/chromium.org/d/topic/chromium-dev/fm5Oe_AC3Sc/discussion>
(although not stated there, that includes libav).

Now the initial response there is not enthusiastic (which doesn't
surprise me), but do you think there are some points useful for the
discussion I'm not aware of?

What are the main challenges of keeping up-to-date with latest ffmpeg
API changes? How do other projects deal with that?

If there is anything else you want to share/say about this, please do.
