User Mode Video Capture Device, is it possible ?

Hi !

I would like to know if it is possible to create a simulation of a video
capture device in user-mode ?
If not, how to make communicating a kernel-mode (TestCap like) capture
driver with user-mode, win32 apps. ?

My problem :
Windows Media Encoder takes only files or Devices as sources for encoding. I
have a multicast MPEG2 stream over a LAN. I would like to capture IP MPEG2
stream, decode it and send for encoding to a Windows Media Encoder... Have
you any better idea than Driver Development ? Thanks in advance !!!

Surely. Write a DirectShow component or - simpler - an ancient-style Video for
Windows driver.

Yes, it is possible.
I've done on multiple occasions. Worked fine.

Ok. What SDK should I use ? How did you do it ?

You use DX SDK.
You have to learn DirectShow and eventually have to create a filter that
supports interfaces that KS proxy exposes and register that filter under
category where you want it to show up.
