      Returns:
      The number of capture devices found.
      Original signature : uint32_t Cap_getDeviceCount(CapContext)

    • Cap_getDeviceName

      com.sun.jna.Pointer Cap_getDeviceName(com.sun.jna.Pointer ctx, int index)
      Get the name of a capture device.
      This name is meant to be displayed in GUI applications,
      i.e. its human readable.
      if a device with the given index does not exist,
      NULL is returned.
      Parameters:
      ctx - The ID of the context.
      index - The device index of the capture device.
      Returns:
      a pointer to an UTF-8 string containting the name of the capture device.

    • Cap_getDeviceUniqueID

      com.sun.jna.Pointer Cap_getDeviceUniqueID(com.sun.jna.Pointer ctx, int index)
      Get the unique name of a capture device.
      The string contains a unique concatenation
      of the device name and other parameters.
      These parameters are platform dependent.
      Note: when a USB camera does not expose a serial number,
      platforms might have trouble uniquely identifying
      a camera. In such cases, the USB port location can
      be used to add a unique feature to the string.
      This, however, has the down side that the ID of
      the camera changes when the USB port location
      changes. Unfortunately, there isn't much to
      do about this.
      if a device with the given index does not exist,
      NULL is returned.
      Parameters:
      ctx - The ID of the context.
      index - The device index of the capture device.
      Returns:
      a pointer to an UTF-8 string containting the unique ID of the capture device.
