I set gfx.wayland.hdr to true and tried opening this video. It says HDR around the cogwheel, but the colors are washed out. With this option disabled the video looks great.
I tried enabling other options, like native_srgb and compositor as suggested online, but no difference.
Oh, I meant overall, not specifically in Firefox, I’ve only used video players directly for HDR, not web players (idk where I’d even find HDR webplayer content tbh)
Ah, got it! Yes, HDR works fine for me in MPV. Maybe I should install an extension to open videos in it 🤔
Nice! Glad to hear it works.
