Return Value

Value Description
S_OK This pin supports this media type.
E_FAIL The pin does not support this media type.


By default, the pin supports a single media type. This method retrieves the supported type by calling the single-parameter version of the CSourceStream::GetMediaType method, and compares it to the proposed type. If your pin supports more than one media type, override this method.
