 This is on https://www.ffmpeg.org/ffmpeg-devices.html

 The current page gives this command for taking a screenshot using the
 fbdev input device:

 ffmpeg -f fbdev -frames:v 1 -r 1 -i /dev/fb0 screenshot.jpeg

 This fails, since the -frames:v option is in the wrong place. I think the
 following is the right command:

 ffmpeg -f fbdev -r 1 -i /dev/fb0 -frames:v 1 screenshot.jpg
