[sampledevicemft] HW Decoder cannot work on Intel Meteor Lake Platform if MEP enabled. #1066

Open vrbear opened 7 months ago

vrbear commented 7 months ago

Testing with USB MJPEG Camera.

Enable HW Decoder in 'stdafx.h', #define MF_DEVICEMFT_ENUM_HW_DECODERS 1

On Intel Meteor Lake platform, if enable MEP (by default), CreateDecoderHW( ) returns failure. If disable MEP, CreateDecoderHW( ) return pass.

Debug found CMultipinMft::ProcessMessage passed MFT_MESSAGE_SET_D3D_MANAGER, but ulParam=NULL

Can you help check this issue?
