The get_NumAuxInputs method retrieves the number of auxiliary inputs that are available. Auxiliary inputs include S-video and composite inputs.
HRESULT get_NumAuxInputs( [out] long *Inputs );
- Inputs [out]
Pointer to a variable that receives the number of auxiliary inputs.
Returns an HRESULT value. Possible values include the following.
NULL pointer argument.
A crossbar filter exposes two auxiliary inputs for each audio input that it supports. That is, each audio input pin has two corresponding auxiliary input pins: S-video and composite video.
The number of auxiliary inputs returned by this method includes all auxiliary inputs, even if the physical input jacks are combined in some manner (for example, with some sort of proprietary or overloaded jack).
The first S-video input is channel 0 and the first composite input is channel 1. Additional S-video inputs are on even-numbered channels and additional composite inputs are on odd-numbered channels.
