 '''Summary of the bug''': When using ffmpeg to record (or ffplay to
 display) from an external device, the frame rate is locked at 10 FPS
 regardless of `-framerate` input.  In this case I'm using the Magewell
 XI100DUSB-HDMI.
 '''How to reproduce''': Use one of the following commands to record or
 display from the device.
 {{{
 ffmpeg -f avfoundation -pix_fmt 0rgb -framerate 60 -i "0:7" -c copy
 ~/Desktop/Capture.nut
 }}}

 {{{
 ffplay -f avfoundation -pix_fmt 0rgb -framerate 60 -i "0:7"
 }}}
