alt Hacker NewsTIL: 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.

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

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.
Not royalty free, unfortunately.
We use JXS when latency is critical. Most h24/265 decodes will have a 10 frame glass-glass delay, JXS drops that to 3 or 4, at a cost of bandwidth (our UHD jxs streams are 1.5gbit rather than 200mbit for hevc)
I've had great results using JPEG-XS to transport video for colour grading in feature film & TV post production. At 3:1 or 4:1 compression ratio is effectively lossless.
It is patent-encumbered though, you have to pay license fees to deploy it.
