Hi everyone,

Description

We are using mfx lib to do hardware decoding on a NUC7i5BNK composed of Intel Iris Plus Graphics 640

When playing the video...

The CPU is stable using this drivers (15.45) :

But as soon as we use 15.46, 15.47 or 15.60

Results

The CPU is increasing from 20% to 100% within 4 hours.

In the end...

 

Looks like a "CPU Leak" from the new drivers located in the libmfxsw64.dll

Hello l.pham

Thank you for joining the community.

Could you provide us with a screenshot of the results (task manager)?

Could you confirm what software are you running when this happens? Is it the Intel® Media SDK?

Regards,

Leonardo C.

I was really busy and had not time to setup the test environment and run the tests again. Sorry for the delay but here are the screenshots of the issue.

We use the MFX SDK.
