MSS HEVC HW Encoder in SkyLake (i7-6700k)

[Rio_L_]

Hi,when i use mss hevc encoder in skylake, i got a issue about hevc hw encoder in i7-6700k platform with WIN7 Pro 64bit, however sw encoder is available.

my command line : sample_encode.exe h265 -i E:\TEST_HEVC\test.yuv -o e:\TEST_HEVC\Test.h265 -w 1920 -h 1080 -b 5000 -f 25 -u speed -hw -p e5400a06c74d41f5b12d430bbaa23d0b

( this command line run success in i7-4790k, but failed in i7-6700k )

run failed result:

Hi Rio, 

Currently Media Server Studio doesn't have support for Skylake. We will be releasing the support for 6th generation soon in the future. Please check our release notes or check back on the forum for the updates. 
Since you have SKL and using windows OS, you can use Media SDK Client to use HEVC HW encode. If you would like to use HEVC GACC enocde(hybrid implementation) which you are  currently using, please wait for the Media Server Studio for SKL.

Thanks,
Surbhi

Thank you for your reply!

how can i use media sdk client to use hevc hw encode in skylake?

I try to use GUID: 6fadc791a0c2eb479ab6dcd5ea9, but the command line run hung-up(CPU load 40%, but don't encode any frame), and sometimes it cause bluescreen.

Hi Rio,

Install the Media SDK Client through Intel INDE Suite, which is available here https://software.intel.com/intel-inde/try-buy. You can download the professional version which free right now.
After you have Media SDK Client installed, you can use latest set of samples from https://software.intel.com/en-us/media-client-solutions-support/code-samples (version 6.0.0.68) You might be using that, please check.
Driver for the windows 10.1 is present at https://downloadcenter.intel.com/search?keyword=Intel%C2%AE+HD+Graphics+530+for+6th+Generation+Intel%C2%AE+Core%E2%84%A2+Processors 

Please test the same scenario again, if you do come across the same issue please let us know. Also, send us the system analyzer logs, system analyzer is present at <installed folder>\mediasdk\tools\mediasdk_system_analyzer.

Thanks,
Surbhi

P.S. Edited to correct the OS Support

Dear Surbhi,

For input 1920x1080p@30fps

May I know how many channels can be encoded (HEVC) by i7-6700k?

I wished to know the max encoder's performance.

H.P.

[Surbhi_M_Intel]

Hi there, 

There are lot of variants which will change/influence the performance. I don't have the exact configuration to test and confirm the result but the performance number which i can confirm is that one can transcode upto 8 streams with AVC->HEVC transcode 1080p@30fps on HD graphics 530 which is in i7-6700K desktop processor. 

hope that helps. 

Thanks,
Surbhi
