+Intel® RealSense™ SDK is a cross-platform library for Intel® RealSense™ depth cameras. This special 2.56.93 ED version enables the D438 prototype cameras which outputs MJPEG image format from the new 13M RGB sensor.
 
 In addition to D438 features, this version of SDK also supports same common capabilities as the regular SDK. It allows depth and color streaming, and provides intrinsic and extrinsic calibration information.
 The library also offers synthetic streams (pointcloud, depth aligned to color and vise-versa).
