I don't always have a connected screen when starting Kodi, so the autostart.sh script sometimes fails.
Is there a way to detect when the display gets connected?

kodi@htpc:~$ xrandr -display :0
Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767

You can just force the edid - search for drm_kms_helper in this forum I documented it.

Thanks, I look into this.
A quick question - sometimes I seem to get black screen, even if I restart Kodi with the screen on. Today I got all other terminals tty2-tty6 totally black. Can this be the reason?

No idea - depends on kernel other things and logs ... good luck.

Thanks, applied, compiled and success.

But one strange thing - with your patch for kernel 4.4 to have correct colors with no banding I had to choose Full range. Now with this patch and newer driver in kernel 4.9 I had to switch to limited range. But once I've done it IMHO final result is better than it was with kernel 4.4. No banding at all (in 4.4 it was sometimes visible). Thanks :-)

The edid stuff is working nicely. And I learned another useful thing today. Thank you!

Latest LibreELEC 8.0 builds (eg. 7.95.1) include a script called "getedid" which should simplify the generation of edid files for Intel and Nvidia users.

Run "getedid create" to install a static version of your current edid.

Run it after you have connected to your TV or amplifier and it will place a copy of the edid in the /flash partition so that you no longer need your TV/Amp to be on before LibreELEC is started).

Fritsch, can you post a ready built 4.9 (4.9.5 as of now) ubuntu kernel with your passthrough patch applied?


RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - fritsch - 2017-01-24

No.


RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - Homerjr43 - 2017-01-27

First, I want to say Thank You to fritsch for all of the hard work!

Please give me a recommendation.

I have a Braswell based Beebox N3000. Which fritsch openelec version should I install for stable KODI. I would like the most stable version that is capable of 4k playback.

Thanks again!


RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - fritsch - 2017-01-27

N3000 can only do hevc 8 bit, you know? You can try Milhouse's v18 testbuilds and see how it goes.

Not that is has anything to do with this thread, but kernel 4.9.5 worked great in 14.04. First kernel with none of the small gfx glitches/corruption for haswell (at least for Celeron 2955u and i3-4130)
Was using 4.4.1 before. I think I tried kernel 4.8.x or (maybe it was 4.6 or 4.7), and I got a kernel panic, hence I stayed on 4.4.1 for quite a bit.


RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - fritsch - 2017-01-28

What was your issue again with self-builing? If you search for make-kpkg in this forum, you see that it is just 5 commands to get a kernel?


RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - fritsch - 2017-01-28

Uploaded 4.9.6 as I built it anyways.
