tutorial_screen_capture ERROR!!!

hello

   when i using the pluging(mfxplugin64_screen_capture.dll) to capture the desktop

mfxVideoParam par;

.......

 par.mfx.FrameInfo.FourCC = params.fourcc;
    par.mfx.FrameInfo.ChromaFormat = params.chroma_format;
    par.mfx.CodecId = MFX_CODEC_CAPTURE;

//par.NumExtParam = 1;
   // par.ExtParam = &mfxextbuf;

..........

everything works well!

when:

mfxVideoParam par;

.......

 par.mfx.FrameInfo.FourCC = params.fourcc;
    par.mfx.FrameInfo.ChromaFormat = params.chroma_format;
    par.mfx.CodecId = MFX_CODEC_CAPTURE;

par.NumExtParam = 1;
par.ExtParam = &mfxextbuf;

..........

mfxSts = MFXVideoDECODE_Query(mfxSes, &par, &par);

always return MFX_ERR_UNSUPPORTED.

Hi Keiyuen,

Is this related to the other post before?

https://software.intel.com/en-us/forums/intel-media-sdk/topic/796416

I think the error message tells me the driver doesn't support this feature, did you confirm with our previous release (Media SDK for Windows 2017) and old sample release(check the samples released in 2017). I think once we have the environment aligned, this should work.
