Isn't the point of JPEG to have lossy compression for your photos that still looks fine? As opposed to something like PNG, which has lossless compression
Reading that it looks like the point of JPEG-XS is to have near-lossless compression for raw photo and video data while having extremely high throughput.

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.

FFmpeg is really great. The only wish I'd have is for the usage to become simpler - both for regular stuff, but also for advanced filtering. 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 fo…

TIL: JPEG XS - an image and video codec that offers both visually and mathematically lossless quality for low latency implementations. Additionally, JPEG XS compressed content is indistinguishable from the original uncompressed content. https://en.wikipedia.org/wiki/JPEG_XS
