-`uvc_backend`:Global UVC Backend select on Linux,optional values: libuvc, v4l2.(v4l2 is lower)
-`color_format`:Color stream coding format.(RGB is lower)
-`depth_registration`: Enables alignment of the depth frame to the color frame.(align_mode is set to HW lower)
-`enable_point_cloud`:Enables the point cloud.
-`enable_colored_point_cloud`:Enables the RGB point cloud.
