Green screen after playing mkv for 10 minutes

Hi,

I’m newbie of OSMC using RPi2, it’s found that some mkv will get whole output screen in green after playing for 5 - 10 minutes, and the sound and subtitles are still going on. Tried hardware acceleration options but no help.

There’s no problem in OpenElec for same mkv. Thanks.

Total green screen sounds like an HDMI problem some set-top boxes manifest wth TVs - somtimes persistent. What display are you using?

i’m using HDMI connecting Sony TV. thanks.

A debug log may be useful.
You could try increasing gpu_mem.

OSMC overclocks by default (OE doesn’t). May be worth disabling the overclock settings.

problem solved after disabled MMAL and increased gpu_mem to 512, thanks.
