I encountered one problem while using the mfxExtEncoderROI in the Media SDK, the problem is after the ROI information have been set, the Query() function failed with MFX_ERR_UNSUPPORTED, I wonder is this feature supported in my current development environment.
The Media SDK version I am using is: Intel Media SDK 2017 R1, the API version is 1.23.
I am using a NUC (https://www.amazon.com/Intel-NUC6i7KYK-Mini-i7-6770HQ-Windows/dp/B01FLDS5SO) with a i7-6770HQ CPU with Iris Pro Graphics 580. My OS is Windows 10 Enterprise 64Bit.
Some parts of the code are listed as follows:
