/**
 * Html5CanvasPipeline
 *
 * A pipeline that connects to an RTSP server over a WebSocket connection and
 * can process JPEG RTP data to produce an motion JPEG data stream that is sent
 * to a HTML canvas element.
 *
 * Handlers that can be set on the pipeline:
 * - all handlers inherited from the RtspMjpegPipeline
 * - `onSync`: called when the NTP time of the first frame is known, with the
 *   timestamp as argument (the timestamp is UNIX milliseconds)
 * - `onServerClose`: called when the WebSocket server closes the connection
 *   (only then, not when the connection is closed in a different way)
