Description

So I've noticed MPV supports a ton of SDR and HDR image formats including .avif, but sadly not .JXR

.jxr is used by Windows Gamebar when taking HDR screenshots (win + alt + prntscreen when in HDR mode) and nvidia's overlay.

Being able to open the images in MPV would be amazing.

We have an app that can open those images with basic lut and peak brightness support, but it's outdated and bad to say the least. (HDR WCG Viewer). The Peak brightness is almost always wrong, etc.

If MPV could open .jxr files, it would just become that much better of a tool!

Research direction

Start by examining mpv's existing image-format support and the path used to open still images. Determine what would be required for JPEG XR HDR screenshots, including the expected HDR handling and peak-brightness behavior; done means .jxr files open reliably with the intended HDR result.
