Recording video with iPhone SE 2020 connected as a camera to a mac results in a 30 fps file even when using camera format "NV12 1920x1440 6-60FPS" and setting Framerate to anything between 30 and 60 in the example's Video settings. Tested with H.265, H.264 and mjpeg codecs, mp4 container.

Problem exists with both FFmpeg and darwin media backends, but with darwin I'm not able to encode with 60 fps at all, while with FFmpeg, choosing a lower res camera format works fine:

"NV12 1920x1080 3-60FPS" the resulting file is has 59.99 fps.

Tested with widget example, but it seems like the declarative example has the same problem.
