The filter wide extension provides the flexibility of having any number of streams between itself and device Ks filter. This component has access to MF APIs, thread pools, GPU and ISP resources.

#Avstream camera driver

User-mode capture driver extension supplied by IHVsДevice Transform Manager that manages devproxy and Device MFT. This topic outlines the design of a device-wide extension running in user mode that can be used to perform post-processing common to all streams. The DMFT can receive frames from all the streams of the device and it can expose any number of output streams as per the requirement. Further post processing operations on the frames can be done inside the DMFT. The DMFT receives post-processed frames from the device. This is a per-device extension component that IHVs supply, and the capture pipeline inserts as the first transform, post-capture. The video capture stack in Windows supports a user-mode extension in the form of DMFT.
