CBasePin.Inactive 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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The Inactive method notifies the pin that the filter is no longer active.

Syntax

virtual HRESULT Inactive();

Parameters

This method has no parameters.

Return value

Returns S_OK.

Remarks

When the filter stops, the CBaseFilter class calls this method on all of the filter's connected pins.

This method does nothing in the base class. Derived classes should override this method to free any resources obtained by the CBasePin::Active method; for example, to decommit the pin's allocators.

The filter graph manager's internal state is not updated until after this method returns, so do not test the state from this method.
