Research direction

Start by comparing the HWMediaSource and HWMediaStream implementation with the referenced commit, fee76f2c. Trace how the custom MFT is enumerated and how IMFTransform attributes and MFT calls are handled in IMFMediaStream. Done means the installed custom video effect is applied to samples when the camera launches.

Description

Hi , I want to modify the HWMediaSource/HWMediaStream such that the samples are processed with a custom MFT based Video Effect. I built out and installed a UMDF driver based on HWMediaSource. I also have a custom MFT implemented as a separate DLL project which I am then enumerating in my IMFMediaStream class(using the CLSID and MFT category). I tested that My effect is enumerated and registered properly. But my attempt at the approach is still not adding any Video Effect to the stream when I launch the camera. I followed this PR for reference on how to include IMFTransform attribute and call the MFT functions in IMFMediaStream class. Any leads on the implementation and how to get it working?
