CTransformOutputPin.SetMediaType method
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The SetMediaType method sets the media type for the connection.
Syntax
HRESULT SetMediaType(
const CMediaType *mt
);
Parameters
-
mt
-
Pointer to a CMediaType object that specifies the media type.
Return value
Returns S_OK.
Remarks
This method overrides the CBasePin::SetMediaType method. It calls the filter's CTransformFilter::SetMediaType method to inform the filter.
The pin must verify that the media type is acceptable before calling this method.
