3.1.2. Stream Manager

The Stream Manager establishes the connection with the video source in order to grab the individual frames and send them, together with a timestamp, to the processing components. Sources can be RTSP/HTTP streams (IP cameras), WebRTC streams (web-based video providers), or video files (for non-real-time applications or testing purposes). The DF can process multiple sources at once. For every source a Stream Manager instance is created. It also receives the resulting data from the Collector component and is able to stream it together with the input video stream through a WebRTC connection mediated by the Server. Stream Manager and all pipeline components are implemented in Python.
