Comment (by ddennedy):

 Hey, I ran into this problem too. I can test a patch. The problem is not
 specific to arm64. Running macOS 12.7 on my M1 machine and 14.5 on the
 Intel. Setting up a remote connection might prove difficult, but I can buy
 you a Logitech webcam.
 I think commit e37b15e26fbc7bc31a86a4a2c7c798e20d4f4c2c is suspicious.

 Under `if (mediaType == AVMediaTypeVideo) {`
 it starts out with only `AVCaptureDeviceTypeBuiltInWideAngleCamera` (see
 "BuiltIn")
 and it never adds `AVCaptureDeviceTypeExternal`.

 Also, my iPhone does not appear as it did in previous versions either
 (`AVCaptureDeviceTypeContinuityCamera`).

 I will test a change like
