Yes this is currently/still broken for me on all my builds

Another mystery is that for video frame CMSampleBuffers, they are always returning outputDuration as kCMTimeInvalid. Even in the Apple sample app AVMultiCam this is the case. So I can't calculate the trim values from the duration. The documentation says this should only return 'invalid' if there is an error, but I have no idea how to check for this error.

Hmm, here to report this was working flawlessly for me on Xcode 14.3, probably couple dozen times, until just now it stopped working all of a sudden.
