Linux VAAPI: Nuc, Chromebox, HSW, IVB, Baytrail with Ubuntu 14.04
Remote won't work on linux, see: https://communities.intel.com/message/281967

The Bios writers of Intel f**cked it up again ...

And as you are at it, please post a full dmesg | pastebinit - something looked interesting in there concerning the CIR.

No further drm errors in dmesg or the kernel log after downgrading the kernel to 3.18.8, also fixed my wifi card (that i dont use) by backing the kernel down. FYI.


Looks like i spoke too soon, as the drm errors continued and exiting the Dim screen saver was not working.
So i implemented drm_kms_helper for booting with the AV and TV off, and this so far has been stable and no issues to report.

cat kern.log | grep drm

For the Baytrail people, I have build a kernel with the turbo fix. This solves the full freeze on quad core BYTs:

Code:
wget  https://dl.dropboxusercontent.com/u/55728161/linux-headers-3.19.1-legacy-turbo%2B_3.19.1-legacy-turbo%2B-10.00.Custom_amd64.deb

sudo dpkg -i *3.19.1*deb

Don't forget the firmware I suggested in the very first post.

Hi again! Everything working fine but just one question. Any chance to use MCDI with 0-255 RGB selected in the driver? I'm using an Intel HD4600 and I set the RGB to 0-255 and activated the 16-235 option in Kodi to avoid banding (If I selected all in 16-235 I have banding).

Yes, I know if I turn off vaapi render and use Yadif all is ok but I prefer MCDI, I think offer better pq.

Thanks again fritsch Smile

@fritsch - maybe you will update the first post to the new firmware Version: linux-firmware_1.143_all.deb
and thanks for the kernel - runs well :-)

No - that's the sad design bug of intel's VAAPI - no chance.

Fixed and added it to the first page. Hopefully with 4.0 all those bugs are fixed.

everything working fine now, I repeat the HowTo. thnkyou Fritsch
but one question:
I have now Kodi 14.1 running, but no PVR Addon on my System. Where do I find them?
I Need XVDR ore VNSI to get LiveTV running on my NUC.
sudo apt-get update
apt-cache search vdr |grep -i vnsi

and then install it - they are packaged.

Hi

I am experiencing a memory leak problem in kodi when I try to play iptv streams. On every iptv stream played the kodi player eats up about 10-15MB memory. This memory is not released.

Following are my pastebints -

Hi,
I'm experiencing the CPU freeze on my Kodi media center. Environment is: i5 - D54250WYK, USB-CEC adapter, Ubuntu 14.04, kernel 3.19, Wsnipex libva, kodi 14.2 beta1. My setup is a bit different from the fritsch one in the first post: not using mini ubuntu but regular desktop distro, not using upstart procedure but kodi default session.

In a random way, average hourly, the NUC freeze the video but the audio is audible; after few seconds freeze completely (I need to power-off the NUC). Sometimes Kodi restart itself without a full freeze (see "kodi.old.log.restart" log file), also when in the menu.

These are the files needed for getting support, taken after a full freeze:
Any help?
Thank you very much,
tode
After I added edid to my nuc I lost sound on playback. I really would like to keep the edid as then it would work after I stop/start tv without rebooting.
Followed the guide in the amd thread ( http://forum.kodi.tv/showthread.php?tid=...pid1824527 )

It might be that the i915 and radeon is not the right modules to add to the initrd, as I get an error in dmesg on audio. But hoping to get help here.

the logs are as follows.
