IVPBaseNotify::RenegotiateVPParameters

The RenegotiateVPParameters method initializes the connection to the decoder.

Syntax

  HRESULT RenegotiateVPParameters(void);

Return Values

Returns an HRESULT value.

Remarks

The Overlay Mixer filter negotiates various parameters (by using the IVPBaseConfig interface) with the decoder or driver. Call this method if any of those parameters (such as the video format or size) change. Currently, the Overlay Mixer repeats the whole connection process. You can call this method even while the graph is playing.

Requirements

Header: Include Vptype.h, Vpnotify.h

Library: None.
