[Openchrome-users] mythtv and xvmc

[Vincent Magnin]

Hello,

Which version of mythTV are you using?

Did you try 0.21-fixes?
> svn co http://svn.mythtv.org/svn/branches/release-0-21-fixes/


Actually, I've a similar config to you (EPIA EN board using CN700) and  
running mythtv.

I do not have found a "stable" working config for XvMC yet.. Thus, I  
can not help you much.

I use mythtv 0.21-fixes, with a playback profil with ffmpeg (so no  
xvmc) and no de-interlace filer, with kernel 2.6.26.2 (so no custom  
DRM), with latest openchrome SVN driver.

My 1.5ghz can play DVB with 70% CPU.

I do not use Via-XvMC profil.. because of system hangs.

Regards,

Vincent
