Nuno Pereira Posted May 30, 2018 Share Posted May 30, 2018 Hello I am a Armbian user in the past 3 or 4 years on a Cubietruck running a headless server in my home. Great machine!!! One of the services that i use is a TVheadend server on cubietruck since wheezy version. But from now and from a couples releases ago, my tvheadend clients the image are it artefacts green on screen. My Armbian version now is stable stretch, and tvheadend server is 4.2. I think this is a kernel problem but i don´t no how to fix. It is possible to downgrade to the 3.4 stable kernel on stretch ? If i remenber in the Armbian wheezy or first jessie releases i don´t have this problem and all the hardware is the same. Link to comment Share on other sites More sharing options...

I am also using TVheadend server but on some more powerful machine. Nanopi Neo with H5 with HTS Tvheadend 4.2.5-29~gd5ecf49 ... IPTV, no artifacts but sometimes I do have troubles with sound delay at the moment. Haven't got time to investigate. You can't downgrade Stretch to the old kernel since it's too old for Stretch ... but you can try this: change CPU governor to performance by editing /etc/default/cpufrequtils and follow by restarting this service or rebooting.

They got a H5-CPU Link to comment Share on other sites More sharing options...

Probably this is my first post here, but i am one of the first armbian users Well i change CPU governor ondemand to performance, and incredible it works! No more green artefacts on screen but maybe more Electricity Costs Thanks Igor for the project. 1 Link to comment Share on other sites More sharing options...
vlad59 Posted May 31, 2018 Share Posted May 31, 2018 if performance works then you can try conservative it should be better for Electricity cost (if that works of course) Link to comment Share on other sites More sharing options...

Today i test 3 clients/3 diferent channels with performance and all great with no green artefacts. Tvheadend server is no more than 30% (console top process) with one or two clients. I don´t no this change so well it ondemand to performance. But great that works Link to comment Share on other sites More sharing options...
