NOERROR A media type was found. VFW_E_NO_ACCEPTABLE_TYPES No agreement on a media type was reached. Remarks
This member function is called during the connection process. It calls CBasePin::TryMediaTypeson both the owning pin and the pin connected to the owning pin; it enumerates the preferred data types on the pin. If one is found, TryMediaTypestries the media type with the pin in a call to the CBasePin::ReceiveConnectionmember function. If this pin proposes a media type, its support is still verified by calling CBasePin::CheckMediaType. The enumerator can list all the media types, even if some of them are not currently available.
This member function is protected.
