RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - fritsch - 2018-01-13
Baytrail J1900 - this one has the CPU bug that when switching loads (and therefore C-States) would just freeze, hang and so on. You have two possibilities:
a) Build a kernel that has a workaround for that
b) use the intel_idle.max_cstate=1 kernel parameter to disable them by software (it will get hotter that way)
RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - fritsch - 2018-01-13
For your J1900, you can try to install and boot a 4.14.13 kernel I built for you: http://fritsch.fruehberger.net/kernel/byt/ - download both .deb files and install them at once with sudo dpkg -i
RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - Preacher - 2018-01-14
Fritsch, thanks tremendously for your efforts. Both files downloaded, installed, and a reboot confirms they're now in use:

Not sure if it's of any concern, but had some warnings crop up during the install:

Nonetheless, everything seems fine; I'm currently soak-testing it with an episode downstairs that it previously crashed on.
The previous build would bomb out every 30 mins, you can see the (list) of crashlogs here: http://paste.ubuntu.com/26385087/ - I take it the known CPU bug means none of these are of any use? If so, I'll clear them out and await new ones.
Thanks again for your speedy response; I'm hoping to transition everything over to this new silent box and I'm still getting caught out with finding some OS-level oddities, but it's reassuring to hear that some aren't just known issues but workarounds are also available.
nb: in the light of this issue, should I hold off on future kernel updates? Thinking newer Canonical-supplied kernels may lack the tweaks you've done here.
RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - fritsch - 2018-01-14
Test it for a few more days. Remove the other crashlogs so we can look into the new ones when your system crashes and burns again.
RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - Preacher - 2018-01-14
Thanks... but the regular 30-min crashlogs are reapparing again. http://paste.ubuntu.com/26386408/ is the latest one.
Peculiarly, a few earlier crashlogs show issues with files I was playing fine. I don't recall the screen blanking nor Kodi resetting in this time, so it looks more like a dump than an actual crash and restart.
Would earlier logs help also? Appreciate you looking into this issue, Fritsch.
RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - fritsch - 2018-01-14
It's caused by this addon:

Remove it please.
RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - Preacher - 2018-01-14
Removed! Will see if I get another crashlog showing up. For a few other questions:
- Any suggestions for alternatives? Being UK-based, I picked it from the list... but it won't be any great loss if I have no weather showing up in Kodi.
- Is it possible to add/remove plugins from the command-line, or from the web interface (http://kodiserver:8000)?
- Is the location of crashlogs configurable? Was thinking of pointing it at another directory location to keep them out of the home directory.
RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - fritsch - 2018-01-14
Nope, but please ask those in another thread. No one will find those questions in here :-)
RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - Preacher - 2018-01-14
Good point! New thread forthcoming...
For what it's worth, no crashlog appearing, so it seems Met Office plugin was definitely the culprit for that - thanks!

Hi Kodi Team,
I think I have the same problem as camelreef with my intel NUC7i3BNH (see his post: #4,567).
Unfortunately, his screenshots and the testfile are already deleted.
I don't experience this issue with ubuntu kernel 4.10.0-37-generic (4k hevc 10bit playback for hours without a problem). All kernels including 4.13 and higher give me this problem after 30-45min into perfect playback. Did somebody ever got this to fix? Apart from that, it's an awesome setup which plays everything in HW!
Here is a log of using the 4.13.16-041316-generic kernel:

Wrong thread. This thread is NOT about Linux-Mint:

I know this is kind of a question that might not be suited for this thread, but I try it anyways.
I got a Intel NUC (nuc5cpyh) with braswell, and I kind of bought it cause I thought it was "future proof" and could do both x264 and hevc in 2160p. I've later learned from you guys in here that it doesn't play hevc in 10bits in HW, making it impossible to play 2160p hevc in 10bit on that NUC.
I wonder if there's some other great hardware to use a my HTPC, wíth about the same specs as my NUC, but also play 10bits hevc?
Thanks.
/Söder
I'll apologize in advance, because my answer will disappoint you. Unfortunately, it is based on fresh experience and as such reflects reality:
- Braswell is not future proof - you should opt for Kaby Lake now to get HW decoding of HEVC in 2160p
- You need bleeding edge Mesa (Intel) drivers and latest Kodi agile (from git), see my post for instructions: https://forum.kodi.tv/showthread.php?tid=231955&pid=2543877#pid2543877
- the 7th Gen NUCs have these CPUs, but unfortunately there are issues with DTS-HD bitstreaming on Linux. I had a Gen 7 i3 NUC and was unable to get passthrough of HD audio working (but hw encoding of the video worked
Short answer: Buy a desktop PC (mini ITX H270 board for example, if you want it small) and use a Kaby Lake CPU on it. Then follow step 0 of Fritsch's guide in first post, and follow my instructions from step 1.
Then you'll have a future proof system capable of HW decoding 10bit HEVC 2160p, and also full HD audio passthrough support. The result of my search for the ultimate HTPC.
For more general advice on hardware picks, I would consult wrxtasy's guide here: https://forum.kodi.tv/showthread.php?tid=252916
I miss being able to see hevc 4k 10bits on my (for now) not HDR ready TV, and I returned once again to your post to find the url to the guild.
I think that the Vero 4K could be something for me. It's not android, and seems to be able to do a lot of stuff I want. Do you guys think it's a great device?
If not, what is it missing in your opinions?
Thanks.

Repost all your logs .. no crystal ball here.
RE: Intel VAAPI howto with Krypton v17 based on Ubuntu 16.04 server - schrackin - 2018-02-07
In the meantime, i managed to solve it. I disabled pulse audio globally, so i can use alsa instead and now it works as expected.
Thanks for your help.
