I have tried altering the Info.plist of terminal apps running the above command and I have enabled legacy cameras in safe mode:

system-override legacy-camera-plugins-without-sw-camera-indication=on

Are there other things I can try or resources to look at? Is a down-rev version of ffmpeg likely to help or hurt?

Hi @jbogari, I'm not sure what you're expected from that command. I see that the -list_devices request worked. If you then want to use one of them as an input, do something like ffmpeg -f avfoundation -i 1 and include whatever parameters you need to match the supported framerates/sizes of the selected device. There's more info at https://ffmpeg.org/ffmpeg-devices.html#avfoundation.

@jbogari Is this still an issue? Which of our formulae does it refer to?
