wrap

public static SendableCameraWrapper wrap(VideoSource source)

Gets a sendable wrapper object for the given video source, creating the wrapper if one does not already exist for the source.

Parameters:

source - the video source to wrap

Returns:

a sendable wrapper object for the video source, usable in Shuffleboard via ShuffleboardTab.add(Sendable) and ShuffleboardLayout.add(Sendable)

wrap

public static SendableCameraWrapper wrap(String cameraName, String... cameraUrls)

Creates a wrapper for an arbitrary camera stream. The stream URLs must be specified using a host resolvable by a program running on a different host (such as a dashboard); prefer using static IP addresses (if known) or DHCP identifiers such as "raspberrypi.local".

If a wrapper already exists for the given camera, that wrapper is returned and the specified URLs are ignored.

Parameters:

cameraName - the name of the camera. Cannot be null or empty

cameraUrls - the URLs with which the camera stream may be accessed. At least one URL must be specified

Returns:

a sendable wrapper object for the video source, usable in Shuffleboard via ShuffleboardTab.add(Sendable) and ShuffleboardLayout.add(Sendable)
