CPU load and privete bytes of Quick Sync softwae is ever increasing.

Suzuki__Hidekazu · ‎11-20-2017

Hello.

I have 2 issues on H.264 decoding software using Intel media SDK - Quick Sync hardware decoding.

Issue 1: CPU load of the software is ever-increasing. It reaches to 100% in 5 or 10 hours then keep 100%. We checked using process explorer and found there is many MFXVideoVPP_GetVPPStat threads (150 threads) and CPU load of each thread is ever increasing.

Issue 2: Private bytes of the program is ever-increasing. It seems memory leak.

My environment:
Windows10 Enterprise 1607
16GB memory
SkyLake Xeon E3-1275 v5 (I have same issues on KabyLake Xeon E3-1275 v6)
Driver version on device manager: 22.20.16.4815 (Old version driver didn't have these 2 issues but it had more critical issue so I cannot use the old driver.)

I need solution of these 2 issues ASAP. Kindly give me any advice.

Hello,

I have exactly the same problem.

Doing H264 decoding, after some time the CPU increase with a lot of MFXVideoVPP_GetVPPStat threads

My environement : CPU I5 7260U + Iris 650. Driver 23.20.16.4877

The same software works fine with : CPU I5 6300U + HD520. Driver 21.20.16.4550

This is really a big big issue.

Hi Suziki San,

Sorry for the late response, do you have a reproducer?

We might have some issue with clean up the used frame buffer which causes the memory management issue. Could you double check if your issue are the same as following posts:
