[FFmpeg-devel] [PATCH] x11grab: add followmouse option

[livibetter]

A patch to enable x11grab to follow mouse pointer.

Sample commands:

# Make grabbing region follows the mouse and keep mouse pointer at center
$ ./ffmpeg -f x11grab -s vga -r 25 -i ':0.0;followmouse' out.mpg

# Make grabbing region follows the mouse, but only move the region
when mouse pointer reaches within 100 pixels to the edge of region
$ ./ffmpeg -f x11grab -s vga -r 25 -i ':0.0;followmouse=100' out.mpg

Sincerely yours,
Yu-Jie Lin
