Screen Capture Fails on Intel i7 6th gen CPU/GPU

[Ramashankar]

Hi,

I am using Intel screen capture plugin from [Intel(R)_Media_SDK_2016.0.1] and sample code from [Intel Media SDK Samples 2016 6.0.0.142]. I am facing a strange issue on 6th gen laptop that if I configure capture plugin to output in RGB32 format then it works well, but if I set to output in NV12 then m_mfxSession.SyncOperation() is always failing with MFX_ERR_DEVICE_FAILED error.

This issue is observed on few laptops and all those were having 6th gen CPU and Windows7 64 bit OS. One of that environment is as following:

OS: Microsoft Windows 7 (6.1) Professional 64-bit  Service Pack 1 (Build 7601)
CPU: Intel(R) Core(TM) i7-6820HQ CPU @ 2.70GHz (Skylake)
GPU: Intel(R) HD Graphics 530
DriverVersion: 20.19.15.4331
DriverDate: 11/20/2015

As per windows update, there is no further updates available for this graphics driver.

My screen capture plugin configuration is as following:

Output format :NV12

Input Resolution :1920x1088

Crop X,Y,W,H :0,0,1920,1080

Output Resolution :1920x1080

Frame rate :24.00

Memory type :system

MediaSDK impl :hw

MediaSDK version :1.17

So, can you please help me out to find out the root cause and its fix? Is it any known issue or limitation with 6th gen CPU + Windows7 OS combination?

Hi Mark,

Is there any update on this issue?

[Mark_L_Intel1]

Sorry for the late response, I have some problem to find the right equipment, I have a solution now but I need a couple days to reproduce the issue.

I have submitted a bug now for trace and communicate with dev team now, I think this could save some time.

Could you tell me what the full reproducing steps and especially the command line?

Hi Mark,

I am not using it as command line but as an lib in my actual application. Issue was reported by one of our customer and through my app logs I found the issue with NV12 format. I don't have that hardware environment so I am unable to check it, but based on my configuration, the command line should be like this:

sample_decode capture -p 22d62c07e672408fbb4cc20ed7a053e4 -hw -scr:w 1920 -scr:h 1080 -f 24
