CBasePin::SetMediaType
Microsoft DirectShow 9.0 |
CBasePin::SetMediaType
The SetMediaType method sets the media type for the connection.
Syntax
virtual HRESULT SetMediaType( const CMediaType *pmt );
Parameters
pmt
Pointer to a CMediaType object that specifies the media type.
Return Value
Returns S_OK.
Remarks
This method establishes the format for a pin connection. Before calling this method, the pin calls the CBasePin::CheckMediaType method to determine whether the media type is acceptable. Therefore, the pmt parameter is assumed to be an acceptable media type.
In the base class, this method sets the CBasePin::m_mt member variable and returns S_OK. A derived class can override this method if it requires notification when the media type is set.
Requirements
** Header:** Declared in Amfilter.h; include Streams.h.
** Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
