Hey! It's still not working properly in Firefox 79 Oo Rly??? It's not a platform issue, on Windows and Linux, and Android is absolutely same, Firefox not working with HDR.

To have a roadmap here let's point out some tasks we need to finish to have HDR support on Linux:

• Extend existing NativeLayerWayland() to support external images (that's how video frames are injected to renderer). MacOS variant is here: https://phabricator.services.mozilla.com/D84638
• Extend DMABufSurfaces to hold HDR YUV surfaces (10-bit formats)
• Extend DMABufSurfaces to hold HDR color data
• Pass HDR data from FFmpeg decoder via DMABufSurfaces to MozContainer (or something else) and apply them during wl_surface_commit
• Propagate Linux/HDR support so web playes can serve us HDR content (i.e. clips in bt.2020 color space with yuv420p10 bit planes)
• Optionally update NativeLayerRootWayland to do local composition (by GL?) and send to Wayland compositor as less subsurfaces as possible.
