SetGPRM Method

  • Article

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

Note

This component is available for use in the Microsoft Windows 2000, Windows XP, and Windows Server 2003 operating systems. It may be altered or unavailable in subsequent versions.

 

The SetGPRM method sets the specified general parameter register to the specified value.

MSWebDVD.SetGPRM(iIndex, nValue)

Parameters

iIndex

Specifies the general parameter register to set as an Integer. The Integer value must range from 0 through 15.

nValue

Specifies the new value for the register as an Integer.

Remarks

General parameter registers, or GPRMs, are 16-bit registers that each disc can use in unique ways for temporary data storage. A player application does not need to access these registers for any standard playback or navigation control using the MSWebDVD object. This method is provided for player applications implementing advanced functionality. Do not attempt to modify the GPRMs directly unless you have a thorough knowledge of the DVD specification and the ways in which the GPRMs are used on the particular disc to be played. Changing these values can result in unpredictable behavior.
