Class InputInfo

java.lang.Object

au.edu.jcu.v4l4j.InputInfo

public class InputInfo
extends Object

Objects of this class encapsulate information about a video input.

• The name of this input
• The supported standards (V4L4JConstants.STANDARD_PAL, V4L4JConstants.STANDARD_SECAM, V4L4JConstants.STANDARD_NTSC or V4L4JConstants.STANDARD_WEBCAM)
• The input type (V4L4JConstants.INPUT_TYPE_TUNER or V4L4JConstants.INPUT_TYPE_CAMERA)
• The TunerInfo object associated with this input if it is connected to a tuner.

You do not directly instantiate InputInfo objects. Instead, they are created by the corresponding VideoDevice object through its VideoDevice.getDeviceInfo() method.
