From bf9b9c3bd0d0fe9d9116cbe287559bad5efe00fc Mon Sep 17 00:00:00 2001 From: Alexander Preisinger Date: Thu, 28 Feb 2013 19:55:02 +0100 Subject: wayland: add wayland support All wayland only specific routines are placed in wayland_common. This makes it easier to write other video outputs. The EGL specific parts, as well as opengl context creation, are in gl_common. This backend works for: * opengl-old * opengl * opengl-hq To use it just specify the opengl backend --vo=opengl:backend=wayland or disable the x11 build. Don't forget to set EGL_PLATFORM to wayland.
