labrat dmesg

When one plays back a video file of sufficient resolution (I tested with
4096x2160), on a display of sufficient resolution (tested with 3840x2160), =
the
video signal is irregularly lost, generally for 2 or 3 seconds.  The entire
video signal is lost, the monitor acts like the video cable is unplugged.

To reproduce:
        get the file http://www.bobdbob.com/~tjohnson/line_finders.mkv
        mplayer -fs -zoom -lavdopts threads=3D16 -vo gl line_finders.mkv
        using a 3840x2160 display

I have reproduced the problem on two separate but more or less identical
machines.  It seems to be dependent on the model of video card.

It does not occur on a 1920x1080 display.  If a machine has two monitors, o=
nly
the high resolution monitor will glitch, even if it is not showing any of t=
he
video.=20=20

It does not occur when the video file is low resolution.  A 704x480 pixel f=
ile
or a 1920x1080 pixel file will play back full screen on a 3840x2160 display
without glitching.

Disabling acceleration fixes it, but results in a useless frame rate.  (Acc=
el
off) AccelMethod None has the same effect.  "-vo x11" has the same result,
stable but with a frame rate of about 1 Hz.
