CTransInPlaceInputPin::CheckMediaType

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.

Requirements

**  Header:** Declared in Transip.h; include Streams.h.

**  Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
