Hi everyone,
DescriptionWe 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
ResultsThe 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.
