Yeah try that 319 I linked. 2048 is ridicioulosly low.

It's not compatible with recent kernels, it won't kompile nvidia module without patches. Maybe I should try but it won't be so easy to compile.

It's good to know, I'll ask them. Perhaps it's indeed nvidia bug or maybe there are several types of cards I have and not all of them support 4k/h264 vdpau. But reagarding to xbmc/kodi.. it should be fixed, in any case.
[edit]
There is no any bug at nvidia. To 4k decoding I need feature set D. It seems my card is GT630 (40 nm) and it has feature set C only. There is also newer GT630 28 nm and newest GT630 rev2 - both supports feature set D. But I have oldest model from 2010 and it supports feature set C only.

Not so bad, my cpu can do it using 20% of the power, but multithreated only. But there is something that I don't understand here - some 4k h264 movies are doceded by kodi multithreated way and I don't need disabling hw acceleration in kodi options.
It seems after recent software update in my phone (actually, new camera app), movies made by it has some problems with multithread in kodi, as mentioned above.

I cannot understand that either: guess why!
Post xbmc.log and mediainfo of those...
I can hack you a patch that will enable mt decoding for everything > 2048. That will kill every other system though :-)

Regarding to hevc and hardware decoding, what about this? https://developer.nvidia.com/nvidia-video-codec-sdk - Linux and Windows are supported and most of nvidia cards. I have never seen any Linux program that use this to decode video, on Windows next upcoming lav codecs version will support hevc decoding with this api.

That's probably what Nvidia VDPAU drivers on Linux and Nvidia DXVA drivers on Windows makes use of.
It would seem the Nvidia 900 series due for launch before the end of month will include H.265 hardware decoding (see http://www.fudzilla.com/home/item/34697-...pport-h265) but as always there's strict NDA's until the day of launch so no one can be absolutely sure. However Nvidia's recent work on Linux would seem to indicate it's coming, for example http://www.phoronix.com/scan.php?page=ne...px=MTc1MTc

That pages about an gpu _encoder_ and only mentioned cuda based decoders - I did not see anything in relation to HEVC

Yes but it seems they started adding some suopport for hevc, look into cuviddec.h in recent cuda. Hardware decoding with this api should be already possible

I checked it, hardware decoding hevc works on Windows using cuvid, via recent lav filters: https://www.dropbox.com/sh/rnlhih0vfoahr...s8BiQNKBta
It also should work with DXVA2. However, vdapu is not yet possible to handle hevc. Are there any plans for CUVID support for Kodi?
