This member function returns information about the negotiated media type for the pin connection.
HRESULT ConnectionMediaType( AM_MEDIA_TYPE * pmt );
Parameters
- pmt
- Pointer to an
AM_MEDIA_TYPEstructure. If the pin isn't connected, this
structure is initialized to zero. Otherwise, the media type is
returned in this parameter.
Return Values
Returns an HRESULTvalue.
Remarks
This member function implements the IPin::ConnectionMediaTypemethod. It returns a copy of the AM_MEDIA_TYPEstructure that was negotiated for the pin connection when the pin was connected.
This method fails if the pin is unconnected. The task allocator allocates the media type's format block. Use the task allocator to free the format block, for example by calling the Microsoft Win32 CoTaskMemFreefunction.
