| Microsoft DirectX 8.1 (C++) |
The CheckMediaType method determines if the pin accepts a specific media type.
Syntax
HRESULT CheckMediaType(
const CMediaType *pmt
);
Parameters
pmt
Pointer to a CMediaType object that contains the proposed media type.
Return Value
Returns S_OK if the proposed media type is acceptable. Otherwise, returns S_FALSE or an error code.
Remarks
This method overrides the CTransformInputPin::CheckMediaType method. It calls the filter's CTransformFilter::CheckInputType method to check the input type. If the output pin is connected, this method also calls the IPin::QueryAccept method on the downstream input pin.
