Description

The ACX_STREAM_BRIDGE_TYPE enumeration describes the Acx Stream Bridge Type.

Constants

AcxStreamBridgeInvalidType

The Acx Stream Bridge is an InvalidType.

AcxStreamBridgeMux

The Acx Stream Bridge is an Mux. This bridge type accepts multiple input streams and allows only one output stream.

AcxStreamBridgeMaximumType

The AcxStreamBridgeMaximumType is used internally for validation. Do not use.

AcxStreamBridgeDefaultType

The default type is associated with one of the valid types for this field. This is the type used if the driver does not override this value.

Remarks

AcxStreamBridge is used by a circuit to propagate stream creation, the stream’s states transitions and DRM settings between the endpoint's circuit stream segments. This object is only used in a multi-circuit (audio composite) scenario.

Example

Example usage is shown below.

    //
    // Add a stream BRIDGE for RAW and DEFAULT modes.
    //
    PCGUID  inModes[] =
    {
        &AUDIO_SIGNALPROCESSINGMODE_DEFAULT,
        &AUDIO_SIGNALPROCESSINGMODE_RAW,
    };

    WDF_OBJECT_ATTRIBUTES_INIT(&attributes);
    attributes.ParentObject = pin;

    ACXSTREAMBRIDGE bridge = NULL;
    ACX_STREAM_BRIDGE_CONFIG bridgeCfg;

    ACX_STREAM_BRIDGE_CONFIG_INIT(&bridgeCfg);
    streamCfg.InModesCount = 2;
    streamCfg.InModes      = inModes;
    streamCfg.OutMode      = &AUDIO_SIGNALPROCESSINGMODE_DEFAULT;

    status = AcxStreamBridgeCreate(circuit, &attributes, &bridgeCfg, &bridge);

ACX requirements

Minimum ACX version: 1.0
