RE: VAAPI: Nuc, Chromebox, HSW, IVB, Baytrail with Ubuntu 14.04 - gurabli - 2015-05-23

fritsch, what do you think, will the N3150 be good enough for proper hw deinterlacing of 1080i material, and L3 upscaling, looking at the frequency and 12 EU? Important, since probably Asrock will only release N3150 version with DC, and not N3700.


RE: VAAPI: Nuc, Chromebox, HSW, IVB, Baytrail with Ubuntu 14.04 - fritsch - 2015-05-23

Basically I don't think.

I will test the hw, when it is available.


RE: VAAPI: Nuc, Chromebox, HSW, IVB, Baytrail with Ubuntu 14.04 - gurabli - 2015-05-23

So probably we will need N3700 for that? Btw, will the deinterlacing or upscaling, or maybe both be limited?


RE: VAAPI: Nuc, Chromebox, HSW, IVB, Baytrail with Ubuntu 14.04 - fritsch - 2015-05-23

"I don't think" <- that means I don't speculate until I have something to test in real hardware. 12 EUs should be far enough.


RE: VAAPI: Nuc, Chromebox, HSW, IVB, Baytrail with Ubuntu 14.04 - gurabli - 2015-05-23

Sorry, I misunderstood. You are right. They should be available soon, we will see. Until then, I hope N3150 will do everything required.


RE: VAAPI: Nuc, Chromebox, HSW, IVB, Baytrail with Ubuntu 14.04 - gurabli - 2015-05-30

ASRock N3150-itx and N3700 boards appeared for sale at Dutch and Austrian shops! Price around 85-120 EUR respectively, which is I believe a quite fair price, especially as it is expected to drop with the usual 20% or so within quite short time. Looking very much forward to the first Kodi reviews, especially for the N3150, as this board will probably have a DC version too.

Hmm.

Anyone have any issues with the latest kernel update in Ubuntu 15.04 killing all audio?

There were a few updates, but from memory none of the others stood out, so I think it must be the kernel update.

Suddenly my Asus Chromebox has no sound.

Reminds me of why I usually only use LTS releases...

Also reminds me of back in the early Gentoo days when every update was a russian roulette. It might work fine, but you might neeed to troubleshoot for 2 weeks to get sound/networking/whatever back :p

Ah, thanks for the link. Did a quick search before posting, but for some reason didn't come across it.

To solve the issue, just install a mainline kernel:

Code:
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0.4-wily/linux-headers-4.0.4-040004_4.0.4-040004.201505171336_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0.4-wily/linux-headers-4.0.4-040004-generic_4.0.4-040004.201505171336_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0.4-wily/linux-image-4.0.4-040004-generic_4.0.4-040004.201505171336_amd64.deb

sudo dpkg -i linux-headers-*4.0.4*deb linux-image-*4.0.4*deb
sudo reboot

Thanks.

I started out with 14.04, but updated the kernel to avoid the video problem detailed on your first post. I went with the mainline kernel (tried a few different ones, 3.19.0, 4.0.0, etc.) and all of them had weird video freezes in Kodi for me.

Going to the non LTS 15.-04 was actually a last resort for me, but everything worked, so I stuck with it, but the downside is you get some updates in a non-LTS release on occasion for which the "stable" classification seems like a little bit of a stretch.

It's one of the known sacrifices with Linux though. When you have latest gen hardware, the kernel drivers go back and forth for a while until things smooth out.

That 3.19 audio outage was an Ubuntu fault ... they wrote a plain wrong patch ... see the other thread.

Oh, of course it is. They seem to push stuff prematurely on the non-LTS releases.

Its like LTS has become the new "stable" and "non- lts stable" has become the new beta.

But anyway, this is seriously off topic :p

Hi,

I have tried to follow the instructions from post #1 and my machine has been crashing everytime I try to play a video in Kodi.

Following your indications here I have the logs you requested. Thanks a lot!!

Wrong kernel. You did not follow the howto at all, right? You are neither in video nor audio group and you have full blown pulseaudio server running.
