Return Values

Returns an HRESULT value.


This method connects these two pins directly or indirectly, using transform filters if necessary. The method either succeeds or leaves the filter graph unchanged. The filter graph manager attempts a direct connection. If that fails, it attempts to use any available transforms provided by filters that are already in the filter graph. (It enumerates these in an arbitrary order.) If that fails, it attempts to find filters from the registry to provide a transform. These will be tried in order of merit.


DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
