CBaseVideoRenderer.JoinFilterGraph 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 JoinFilterGraph method sends EC_WINDOW_DESTROYED event notification when a filter is removed from the filter graph.

Syntax

HRESULT JoinFilterGraph(
       IBaseFilterGraph *pGraph,
  [in] LPCWSTR          pName
);

Parameters

pGraph

Pointer to the filter graph to join.

pName [in]

Pointer to the name of the filter being added.

Return value

No return value.

Remarks

This member function overrides the CBaseFilter::JoinFilterGraph member function. If the filter is leaving the filter graph (pGraph is NULL), it sends an EC_WINDOW_DESTROYED event notification so that the resource manager does not hold on to the renderer as a focus object.
