Re: "xv" video with intel graphics?

unfortunately, upstream mpv is extremely hostile to NetBSD.
actually, if you asked some users of Linux  and other BSDs,
upstream mpv is extremely hostile to everything.

i recommend sdl video outputs. if this and opengl don't work
something needs fixing system wide, falling back to x11 is
indicative of a problem. ffplay (another player) should also
be extremely reliable.

my impression is that the "2014" driver should no longer be
needed - at some point newer NetBSD automatically uses an uxa
AccelMethod on older intel gpus.  but even software gl with 
llvmpipe and wsfb should be better than broken-mess-drivers.
