The size of the native video has changed.

Parameters

Remarks

This event notification is sent whenever a video renderer detects a change in native video size. An application might use this notification to negotiate space in a compound document. The actual video dimensions are available through the IBasicVideo control interface. The DirectShow renderers detect whether the video has changed size or not prior to sending these events.

For information on how to use this event code, see CBaseFilter::NotifyEvent.

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.
