Intermitent black screen during play back - GloW - 29th Mar, 2013 06:08 AM
Hello
First thanks for this amazing distros, it is working great and far smooth than raspbian with xbmc over it.
I have a problem.
When i play a video in xbmc, it happens that there is an interemittent black screen of 0.5 seconds.
It is not regular at all, sometimes i got 4 black screen in a row, then nothing in the next 5 minutes.
Some videos have this problem, others have not. of course it is not in the video.
I suspect some kind of overflow, but i cannot see any terminal output to check on that.
So here my questions :
Do you have any ideas what can be the cause? and how can i fix this?
Is there any way to get the terminal output of the video player, in a log file for example ?
Is the video player used by xbmc omxplayer? i've tried to use omxplayer to play the video but the package is not even installed, so how xbmc play videos?
Thanks
Edit:
Here are some mediainfo :

For me the main difference is the audio, black screen one got 6 channels.
I'm gonna check on that.
RE: Intermitent black screen during play back - GloW - 29th Mar, 2013 09:29 AM
I was quite right, this black screen was an audio problem.
In xbmc settings, system->audio , i was configured in 7.0 , i've changer it to 2.0 and this black screen problem reduced a lot, but still not completelly.
anyone having same problem ?
i've found how to get the log, enable logging in system->logging then look in .xbian/temp/xbmc.log, but it's pretty extensive and incomprehensible.
I'm still unable to find the actual path to the omxplayer used in xbmc. or may be it is built inside it?

Omxplayer is built directly into the xbmc.bin
RE: Intermitent black screen during play back - GloW - 31st Mar, 2013 06:31 AM
well thank you, i gonna use my raspbian image for direct use of omxplayer i guess.

sudo apt-get install omxplayer
sudo service xbmc stop

I have the same problem, I did a fresh install and the first 3 days did work perfectly.. then it started again.
I dont want to switch to another distro cuz I like xbian, but I have no choice until someone find the solution..
RE: Intermitent black screen during play back - IriDium - 24th Jun, 2013 11:18 PM
Is "output to all speakers" in System -> Audio set?
This has been known to cause problems, so if it is set, remove it and see if that improves things.
