Crash in MFXVideoENCODE_Query() in 64 bits Windows

Hello.

We are encountering a random crash in the MFXVideoENCODE_Query() function in 64 bits Windows on a lot of Intel HD Graphics.

The crash occurs between 80% and 100% of the times, depending on the platform.

Version : Intel(R) Media SDK 2018 R1 8.0.24.0 (Windows 10 64 bits)

We do not encounter the issue when running in 32 bits (or when using D3D11 memory instead of system memory, in 32 or 64 bits).

The issue can be reproduced with your intel_media_sdk_sample_encode.exe application and your YUV sample file.

We use the following command line:

intel_media_sdk_sample_encode.exe h264 -i test_stream_176x96.yuv -o out.h264 -w 176 -h 96 -g 256

Could you please let us know if you can reproduce the issue, and if you can provide a fix?

Thanks and best regards,

Xavier
