(Yes I know there are repos to get binaries for some, things like deb-multimedia.)
The hardest part IMO is getting the necessary codecs to work; this can take a little while. If you know what audio and video codecs you want and need, and if you get them installed properly, then compiling ffmpeg is really simple and straightforward. It works almost always for me, and I have compiled ffmpeg from source for like +10 or even +15 years.
For reference purposes, my current configure options are:
./configure --prefix=/usr/ --enable-gnutls --enable-gpl --enable-libmp3lame --enable-libaom --enable-libopus --enable-libspeex --enable-libtwolame --enable-libvorbis --enable-libvpx --enable-libxvid --enable-libx264 --enable-libx265 --enable-nonfree --enable-pthreads --enable-shared --enable-version3 --extra-libs=\"-ldl\" --disable-doc --disable-libopenjpeg --disable-libpulse --disable-static
One focus I have is mostly on a few .mp4 files, and for these I think you kind of want x264 x265 and so forth (I think one more codec from google too or so). But it is really quite trivial once you are past the codecs step. You can also start simple with just a few codecs, e. g. one good audio codec and one good video codec. One reason I like to have ffmpeg support many codecs is so I can use mpv, which in itself is really awesome; I like it more than vlc, which is also ok though.
If anyone remembers, avisynth was pretty cool back in the days. You could kind of script video/audio manipulations, a bit like a UNIX/Linux pipe, but kind of simpler, in my opinion. FFmpeg allows for many similar operations, but remembering anything here is ... hard. I'd love for the whole usage API to become much simpler, but it seems nobody among the ffmpeg dev team is considering this. :(
I can't be the only one with that wish though ...
It does not diminish ffmpeg being so great in general, but I think it could be better.

Additionally, JPEG XS compressed content is indistinguishable from the original uncompressed content.

It can be indistinguishable, as long as you stick with lossless or very low compression ratios. It falls apart at typical JPEG XL compression ratios.

> This source provides low overhead capture of application windows or entire monitors. The filter outputs hardware frames in d3d11 format; use hwdownload,format= if system memory frames are required.
This would strongly alter my plans if I were to develop an OSS Discord alternative. Chromium originally looked like a better core to start with largely due to its mature screen capture API. WebRTC is the other big thing, but there are other ways to do that. Native desktop apps (i.e., not browser based) are beginning to look much more compelling to me now.

I wonder if "entire chat app functions as OBS plugin" would work? Would solve the AV streaming side of the functionality.
