[FFmpeg-devel] [PATCH] Fix for xcb based x11grab, trac ticket #4164

[Daniel Moran]

Hi, 

This is the first time I've created/submitted a GIT patch, so I apologise in advance if I have made a mistake.

This is to address an error when using show_region, which would cause part of the captured area to become static.
It looks like the rectangle specifying the capture area was relative to the capture window.

Regards,
Daniel
