Bug#1027452: libmutter-11-0: ffmpeg kmsgrab stopped working after update from 43.2-2 to 43.2-4

[Alexandr Podgorniy]

I figured out the problem. Mutter on wayland uses multiplane 
framebuffer, and it's not compatible with old capture method. It's not 
very hard to implement in software that uses kmsgrab, so it's not mutter 
problem, it's ffmpeg problem. Please close this bug, and sorry for 
bothering.

P.S. I successfully implemented multiplane buffer support it in my 
software, so i hope ffmpeg will get similar fuctionality eventually.
