Bug#803498: mpv: VO opengl{-hq}: Could not create EGL context!

[Andrey Gursky]

Hi,

mpv 0.12 does perfectly work on an intel laptop. I looked into mpv source code
repository and found the explanation. These are the interesting commits:
- vo_opengl: enable X11 EGL backend by default [1]
- vo_opengl: add DRM EGL backend [2]
- vo_opengl: fix backend autoprobing [3]
- vo_opengl: attempt to improve GLX vs. EGL backend detection [4]

It seems there are still issues with autoprobing. Thus you have to choose the
backend explicitly:
mpv --vo=opengl:backend=x11
in opposite to the default one (working on intel):
mpv --vo=opengl:backend=x11egl
