KSPROPSETID_BdaNullTransform

KSPROPSETID_BdaNullTransform is the BDA null transform property set. It is used to instruct a node to pass a signal through without change. Starting a NULL transform on a node effectively changes the node into direct connection from its input to its output with no other function.

The following properties are available:

KSPROPERTY_BDA_NULL_TRANSFORM_START
Disables any transform that the node previously applied to a signal and allows the signal to pass through the node unchanged.

KSPROPERTY_BDA_NULL_TRANSFORM_STOP
Restarts the transform that the node performed on the signal before that transform was disabled with the KSPROPERTY_BDA_NULL_TRANSFORM_START property.

Comments

The network provider filter can use this property set if a node supports it and the network provider needs the signal to pass through that particular node unchanged.
