The new, standard JPEG-XS codec support in ffmpeg 8.1 --enable-libsvtjpegxs seems to have gone a bit under the radar. feel free to install dev files for it and see how it performs? :)
Mmmm. So far I have just tried to install ffmpeg 8.1 from Packman on Tumbleweed to see if they have enabled JEPE-XS support. But unhappily there is currently several dependency issues so ffmpeg 8.1 could not be launched.
As it seems now, JPEG-XS is patent encumbered, so no way for it on openSUSE repos, including multimedia:libs. Maybe this is a problem for Packman too. At least ffmpeg 8.1 released for Tumbleweed and Leap/SLE 15, has not libsvtjpegxs enabled so far. My understanding is that SVT-JPEG-XS from Intel is an OSS implementation under a BSD+Patent license that provides a patent license for the code but not for the underlying JPEG-XS standard. It is the standard itself that is patent-encumbered by requiring a license and royalty. If this also is required for uncommercial use is unclear.
Not sure if ffmpeg set to autodetect it or not by default ...
Also, welcome back!
JPEG-XS is high-lighted as a lightweight image and video compression standard (ISO/IEC 21122) designed specifically for applications requiring high visual quality, ultra-low latency, and low computational complexity.
Unlike standard compression formats (like HEVC or JPEG) that focus on maximum compression ratio, JPEG-XS prioritizes keeping content "visually lossless" while reducing bandwidth, making it ideal for professional video production, IP transport, and real-time streaming.
JPEG-XS providing compression ratios up to 10:1 while maintaining high video quality. The codestreams can be encapsulated in several standard container formats to allow for transportation and storage: MXF, MPEG-2 (MPEG-TS), MP4, HEIF and more.
