The camera widget example crashes when recording is started, using darwin media backend on arm macOS. (works on intel)
Reproducable with Exibel QHD webcam. If the app is first launched with only an iPhone connected as a camera, everything works, even after connecting the webcam and recording with both. Crash output:
