I’m trying to capture in Chrome (latest), Safari or Firefox on MacOS 15.3.1 (latest)
It works in 1080p but not 4k.
I got it to capture ONCE at 4k but only if I started OBS first, then captured there in 4k, then switched to the browser.
However, it doesn’t work reliably.
It also seems to ‘mangle’ OBS and reset the video setting there somehow.
I’m not sure how these systems would interact with each other but clearly there are some side effects happening.
IS there any workaround for this? I haven’t seen anyone else report this problem.
I used a number of 3rd party tools to debug this problem
What’s weird is that it will return 4k but it just has text that says “Not Supported” but this device clearly supports 4k @ 30fps.
