High preset for a 4k webcam records in 1080p

[RoyHP]

Hi, the high preset for my 4k webcam (Logi 4k Pro) records in 1080p and I don't see a way to record natively in 4k. Any idea about this?

Let me know if I can help - thanks!

I'm validating the chosen encoding preset here and then set it in the capture session here.

Right now, the preset must be one of these. This list was taken from older Apple API docs on capture sessions. It looks like there are now significantly more options.

When I have time available I can look at introducing all these newer options.

😉 Or feel free to submit a PR for this if you know how.

Thanks - I'm happy to provide the PR.

Okay so I tried but it gave me "could not set encoding preset '3840x2160' for this device, defaulting to Medium" - I tried some other variations of the preset as well, and got the same message. See attached screenshot.

I'll try to see if OBS can use it at 4k as a sanity check.
