DirectShow filters - missing classes

I am using VS5 with “Windows Mobile

Version 5.0” SDK to develop DirectShow filters and

codecs,

We already have them for win32

platform and we need to port them to mobile

platform.

The problem is that, there are

missing classes and interfaces for the DirectShow version of the mobile SDK

(following):

• CDynamicOutputPin

• IPinFlowControl

• IGraphConfig

• IFilterMapper2

  à although this is

  documented as available for CE, it’s not found in the SDK

  headers.

Can anyone please explain why these

are missing? And is it possible in future to have them implemented?

Is there any code sample for a

DirectShow filter for mobile platform?
