 Per https://trac.ffmpeg.org/wiki/Capture/Desktop#OSX
 I am using AVfoundation (https://ffmpeg.org/ffmpeg-
 devices.html#avfoundation) to capture video and the following capture of
 the desktop results in an unuseable picture:


 {{{
 $ ffmpeg -f avfoundation -i "1:none" desktop.mov
 ffmpeg version 3.2.2 Copyright (c) 2000-2016 the FFmpeg developers
   built with Apple LLVM version 8.0.0 (clang-800.0.42.1)
 }}}

 As a comparison, a similar command for capturing the internal FaceTime HD
 Camera results in a useable picture:

 {{{
 $ ffmpeg -f avfoundation -i "0:none" facetime_cam.mov
 }}}

 NOTE: 3.2.2 is not an option in the New Ticket >> Version pulldown menu
