3	3	WPILib provides a great helper class called [https://first.wpi.edu/FRC/roborio/release/docs/java/edu/wpi/first/cameraserver/CameraServer.html CameraServer] that does most of the heavy lifting. You can read about it [https://docs.wpilib.org/en/latest/docs/software/vision-processing/introduction/cameraserver-class.html here] and [https://s3.amazonaws.com/screensteps_live/exported/Wpilib/2078/6264/Read_and_process_video_CameraServer_class.pdf?1483739157 here]
