CTransformInputPin.SetMediaType method

  • Article

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.
