  • Article

Passes an EC_VIDEO_SIZE_CHANGED message to the filter graph manager.

virtual HRESULT OnVideoSizeChange( );

Parameters

None.

Return Values

Remarks

A video renderer should call this member function each time the video size is changed; this will typically be called once after initial connection. If the renderer can support dynamic format changes (from 320 x 240 to 160 x 120), it should also call it after each change.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
