 You need to start kodi like that: KODL_GL_INTERFACE=GLX kodi (thx to fernet)T 

Thank you very much again for your help.
Hm, it's getting more difficult :-) I use LibreElec. Do I have to modify sytemd config files for that? How do I do that?
With hardware acceleration disabled, HD TV uses nearly 100% CPU load and playback is sometimes not flawlessly.

Yes - there is a posibility to do that. I pinged Milhouse on slack cause I have plain forgotten how to do that on LE :-)

Btw. HD is also mpeg-2 for you? Cause H264 should still work with VAAPI right?

Add the following to /storage/.config/autostart.sh:

Code:

echo "GL_INTERFACE=GLX" >>/run/libreelec/debug/kodi.conf

and reboot.

Note that once PR13700 is merged you'll need to replace GL_INTERFACE with KODI_GL_INTERFACE.
