Getting QuickSync in Celeron N2830 to Work

Hi,

I recently acquired a Intel NUC DN2820FYKH with the Celeron N2830 CPU which according to Intel ARK has QuickSync.

Also, according to Wikipedia, the included GPU, a 7th gen Intel ValleyView(Bay Trail) HD Graphics of code 0F31 has support to both QuickSync and OpenCL. 

I'm trying to install and run Intel's Media Server Studio Essentials 2016 on it, using the gold OS, CentOS 7.1.1503.

But, after many trials I only get the following info:

libva info: VA-API version 0.99.0
libva info: va_getDriverName() returns 0
libva info: User requested driver 'iHD'
libva info: Trying to open /opt/intel/mediasdk/lib64/iHD_drv_video.so
libva info: Found init function __vaDriverInit_0_32
libva error: /opt/intel/mediasdk/lib64/iHD_drv_video.so init failed
libva info: va_openDriver() returns 1
vaInitialize failed with error code 1 (operation failed),exit
Unrecognized device ID 0F31

In some trials in Ubuntu 16.04.1 LTS the command vainfo return correct information, but I can not run the samples. Also, If I install all Intel drivers and libs from Media SDK I end up with the same message of Unrecognized device ID 0F31.

Maybe there is a bug in the drivers and this device ID was not put in the white list or some sort of other problem?

Can some one explain if the N2830 is really capable of using Intel Quick Sync? Is there anything else I need to do in order to get the QuickSync Working or any one could recommend a combination of Media SDK and OS that would make this work?

Thank you!

Hi Daniel, 

From the output of vainfo, we can see your platform is not supported by Intel Media Server Studio.

You can refer to "System Requirements" in Release note Linux* to get more more information for use Intel Media Server Studio. 

 

Thanks,

Zachary

This Celerons have Quicksync enabled.

When come a update that support Celerons?

So why Intel documentations say that the chip has support? This is what most puzzles me.

Is there any other way to make use of QuickSync capabilities instead of using Intel Media Server Studio pre-build libraries?

From a clean install of Ubuntu 16.04, applying Intel patchs on Kernel 4.4 and without Intel Media Server Studio libs I get the following:

The same thing confuses me too. Intel claims a lot of CPU to have quick sync. However, media SDK only supports some of them.

Even worse, new releases stop supporting CPUs that were supported by early versions! Combined with the facts that it's so difficult to use and there are quite a few critical bugs, I doubt Intel is taking this seriously. We have spent several months trying to use QSV in our product, so far I would say it's not ready for production usage yet.

You can try intel open source solution (https://01.org/linuxgraphics) for your CPU, and it look like it already worked for you. i965_drv_video.so is the UMD of intel open source solution.

For intel media server studio, it is not open source and iHD is it's UMD, it usually support n and n -1 platform, Intel Media Serve Studio 2017 support SKL and BDW.

You can base your cpu to select different solution.

If you use window, you can also select Intel® Media SDK "https://software.intel.com/en-us/media-sdk"

 

Thanks,

Zachary

Hi Jiandong.

 

I did not understand the second phrase. Can you explain a little better?

With the open source driver the access to Quick Sync Video is done through VAAPI or they are completely different things?

Also, would a device based an Intel Core I5-5200U or Intel Core I3-5015U be compatible with Intel Media Server Studio 2017?

Thank you.

BDW:  5th Generation Intel Core Processors

SKL:   6th Generation Intel Core Processors

And, you can find following in Release note Linux*.

5th Generation Intel® Core™

6th Generation Intel® Core™

 

Intel Core I5-5200U or Intel Core I3-5015U are 5th Generation Intel Processors with "Intel® HD Graphics 5500", more details info can be searched in http:://ark.intel.com, so they are supported by Intel Media Server Studio 2017.

For open source driver,  your can call VAAPI to access to Quick Sync Video,

For Intel Media Server Studio, you can call MSDK API, it will call VAAPI to access to Quick Sync Video.

@Jiandong Z, thx for the hint with the opensource driver. This works fine with my Celeron G3900
