Description
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 ""`

Research direction
Start by reproducing the issue on OS X with Google Hangouts, LivepeerDesktop via ffmpeg, and OBS using the Facetime HD Camera. Run `ffmpeg -f avfoundation -list_devices true -i ""` to identify the device, then inspect the webcam capture path. Done means the Livepeer stream remains non-interlaced while other apps use the camera and the input is read only once.
