EC_PALETTE_CHANGED

  • 项目

The video palette has changed.

Parameters

  • lParam1
    Zero.
  • lParam2
    Zero.

Remarks

This event notification is sent to the application and the filter graph manager. Whenever a video renderer detects a palette change in the stream, it should send the EC_PALETTE_CHANGED notification to the filter graph manager. The DirectShow video renderers detect whether a palette has really changed in dynamic format or not. The video renderers do this not only to filter out the number of EC_PALETTE_CHANGED notifications sent, but also to reduce the amount of palette creation, installation, and deletion required.

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.
