A version of this page is also available for
4/8/2010
The video palette has changed.
Parameters
- lParam1
Zero.
- lParam2
Zero.
Remarks
This event notification is sent to the application and the filter graph manager.
When 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 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.
