"Cpu Leak" in mfx lib

[Pham__Ludovic]

Hi everyone,

I posted in https://communities.intel.com/message/524741#524741 and got adviced to post here, so here I am

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

The CPU load when we start the program

The CPU load few hours later

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
