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=16 -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, only
the high resolution monitor will glitch, even if it is not showing any of the
video.
It does not occur when the video file is low resolution. A 704x480 pixel file
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. (Accel
off) AccelMethod None has the same effect. "-vo x11" has the same result,
stable but with a frame rate of about 1 Hz.
