Video & HDR On MacOS?

But we are looking into integration MoltenVK to use as a Vulkan -> Metal translation layer for improved features. But that may be a while yet.
As for HDR, theoretically its possible, but on the current OpenGL backend I don't believe it works.

Yeah I know JRVR doesn't use Metal. MoltenVK would be nice!! From looking at what Metal does 'uniquely' with Apple's GPU hardware, I've just been wondering what its capabilities might be in terms of real time scaling.
Thanks for clarifying HDR support. Definitely seems spotty, there's a few other players on MacOS that claim to do it but if you go into their issue trackers, you can see there's some debate about how 'accurate' it is, when referencing QuickTime which apparently may present HDR from retail / home video sources correctly.

Infuse seems to play correctly HDR on Silicon and Ventura. Anyway I am married :-) to JRiver (and to madVR then and JRVR now) on Win so I would like to stick with it on Mac M too. I am following with interest...

Infuse "works" in the sense of a default tone mapping. But it doesn't have the key features of jriver such as:
* Screen brightness setting for HDR to SDR conversion (slider)
HDR contrast discovery (slider)
Use HDR Dynamic peak detection (for tone mapping)
Use historgram to imrpove Peak Detection
Use tricubic interpolation for gamut mapping
*
which are the kinds of things one needs to really do it right.
But it sounds like jriver doesn't offer those options for the Mac either, just Windows.
