I am not a fan of Xcode.  Here are ~160~ 200 problems, the first hundred or so issues were filed mostly in 
July and August 2016 in a fit of rage.  Mostly on weekends working (slowly) on side-projects.  I have also
taken days of my employer's time filing others of these - so the company was not getting value for my time.

I believe a paid intern could have found many of these - just start a screen recorder, and when you see something,
stop and cut a quick movie.  Many have been around for several major versions.
I'm volunteering chunks of my life (15-30 minutes per) to one of the most valuable companies in the world, which seems
kind of messed up. Things get worse the more complex the project and the longer Xcode been's running.

#Capture and stream a webcam To capture using the iSight camera on a Mac, or infact any other webcam connected to the Mac, we can use FFmpeg. First get a list of the devices installed.

ffmpeg -f avfoundation -list_devices true -i "" 

This will list the aviable video and audio devices.

The below will capture at 30fps and the set video size to a file. ffmpeg -f avfoundation -framerate 30 -video_size 640x480 -i "0:none" out.avi
