Codec and DSP IPropertyBag Constants

  • Article

There are two methods of setting properties on the codec and DSP objects programmatically, using either the IPropertyBag interface or the IPropertyStore interface. Most common properties are available through both interfaces. Use of the IPropertyStore interface is preferred over IPropertyBag.
