Interlaced content when multiple apps using the webcam

[dob]

Right now if multiple apps on OS X are using the webcam, such as google hangouts, LivepeerDesktop via ffmpeg, and OBS, the Livepeer stream becomes interlaced as it seems to take the webcam input 2x or 3x instead of just 1x. We need to limit ffmpeg from just reading the webcam input once or find another solution.

This command lists the input devices, and we're looking for the Facetime HD Camera..

ffmpeg -f avfoundation -list_devices true -i ""
