RtVideoStreamingSender¶

//
// This application is to be instantiated on the UE side. It requires that a ~DeviceApp is
// also instantiated on the UE. This module requests the ~DeviceApp to instantiate a
// ~MecRTVideoStreamingReceiver in the MEC system.
// Once the peer MEC application is up and running, this module starts sending packets
// containing video frames as read from the trace file specified in the configuration.
