new VideoConnection()
Video connection.
This class manages an established connection and handles receiving and parsing frames via the ItemHeaderParser class.
Do not create instances of that class directly. Instead call XPMobileSDK.requestStream to first prepare the connection to the
camera. In the callback you will receive instance of the prepared VideoConnection object ready to be opened. Then set
an observer object to receive frames, events and etc and just open the connection.
Video connections cannot be reused. Once closed it cannot be reopened.
