Standard Element GUIDs
The Standard Element GUIDs are used to find a IVCDPropertyElement of a IVCDPropertyItem.
After an IVCDPropertyItem interface has been retrieved with one of the Standard Property Item GUIDs, the property elements of the property item can be retrieved.
#include "tisudshl.h"
The GUIDs are declared in the namespace DShowLib.
The GUIDs are passed to the IVCDPropertyItem::findElement method. The element type is used to specify a sub property of a camera property. For example the exposure camera property can have a value and an auto element. The value element is used to retrieve and set an value (e.g. 114). The auto element is used to enable or disable automation for exposure. An interface to an element is retrieved by adding a string from the Standard Interface GUIDs to the Standard Element GUID.
The Basic Use of VCD Properties article in the Programmer's Guide shows how to use the element GUIDs.
