The Connect method connects the two pins, using intermediates if necessary.
HRESULT Connect( IPin *ppinOut, IPin *ppinIn );
[in] Pointer to the IPin interface on the output pin.
[in] Pointer to the IPin interface on the input pin.
Returns an HRESULT. Possible values include the following.
|VFW_S_PARTIAL_RENDER||Partial success; some of the streams from this pin use an unsupported format.|
|E_POINTER||NULL pointer argument.|
|VFW_E_CANNOT_CONNECT||No combination of intermediate filters could be found to make the connection.|
|VFW_E_NOT_IN_GRAPH||At least one of the filters is not in the filter graph.|
This method connects two pins directly or indirectly, adding intermediate filters if necessary. The method starts by attempting a direct connection. If that fails, it tries to use any filters that are already in the filter graph and have unconnected input pins. (It enumerates these in an arbitrary order.) If that fails, it searches for filters in the registry, and tries them in order of merit. For more information, see Intelligent Connect.
During the connection process, the Filter Graph Manager ignores pins on intermediate filters if the pin name begins with a tilde (~). For more information, see PIN_INFO.
