timestamp_ is only used in GenerateFrame() and its old value is discarded. So it just needs to be a local variable in GenerateFrame(). As a result, we can remove the start_timestamp parameter from the constructor and Init(). Also mark the GeneratePacket() method private because it is only used internally.
