EC_NOTIFY_WINDOW

Notifies a filter of the video renderer's window.

Parameters

lParam1

(HWND) Handle to the window.

lParam2

Zero.

Default Action

This event is used internally by DirectShow. The filter graph manager does not pass this event to the application. Applications cannot override the default action for this event.

Remarks

When a video renderer is connected, it checks whether the upstream output pin supports the IMediaEventSink interface. If so, the renderer sends this event to the upstream filter.

Requirements

  Header: Dshow.h.
