Syntax
virtual HRESULT OnVideoSizeChange( );
Parameters
None.
Return Value
Returns an HRESULT value.
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.
