First of all,i am glad to recive to reply,I have tried two Intel media SDK (Intel(R) _media_sdk_2016.0.2 and Intel(R) _media_sdk_2017.0.1)

First:

INTELMEDIASDK_WINSDK_PATH     C:\Program Files (x86)\Windows Kits\10

INTELMEDIASDKROOT                      C:\Program Files (x86)\IntelSWTools\Intel(R)_Media_SDK_2016.0.2

file: ..x64/Debug/

                          22d62c07e672408fbb4cc20ed7a053e4/mfxplugin64_screen_capture.dll

                          22d62c07e672408fbb4cc20ed7a053e4/plugin.cfg

                          54542616243341e693ae899942ce7355/mfxplugin_camera_pipe64.dll

                          54542616243341e693ae899942ce7355/plugin.cfg

                          lib/igfx_s3dcontrol.lib

                          lib/libmfx.lib

                          lib/libmfx_d.lib

                          lib/sample_common.lib

                          libmfxaudiosw64.dll

                          libmfxsw64.dll

                          sample_decode.exe

                          sample_decode.ilk

                          sample_decode.pdb

commondline :

sample_decode.exe capture -d3d11  -hw -f 25 -p 22d62c07e672408fbb4cc20ed7a053e4 -w 1920 -h 1080 -fourcc nv12  -o output.yuv

yes,work well:
