Example

Example usage is shown below.

    ACX_PROPERTY_ITEM StreamProperties[] =
    {
        {
            &KSPROPSETID_DrmAudioStream,
            KSPROPERTY_DRMAUDIOSTREAM_CONTENTID,
            ACX_PROPERTY_ITEM_FLAG_SET,
            Codec_EvtStreamSetContentId,
            NULL,  // Reserved
            sizeof(KSP_DRMAUDIOSTREAM_CONTENTID) - sizeof(KSPROPERTY), // ControlCb
            sizeof(KSDRMAUDIOSTREAM_CONTENTID), // ValueCb
        },
    };

    ULONG StreamPropertiesCount = SIZEOF_ARRAY(StreamProperties);

    status = AcxStreamInitAssignProperties(StreamInit,
                                           StreamProperties,
                                           StreamPropertiesCount);
