const CMediaType* pmt
);

| Value | Description |

NOERROR |

Remarks
This member function is called during the connection process.
It calls CBasePin::TryMediaTypes on both the owning pin and the pin connected to the owning pin, and it enumerates the preferred data type on the pin.
If a preferred data type is found, TryMediaTypes tries the media type with the pin in a call to the CBasePin::ReceiveConnection member function.
If this pin proposes a media type, its support is verified by calling CBasePin::CheckMediaType.
The enumerator can list all media types, even if some are not currently available.
This member function is protected.
