An Endpoint responsible for connecting to a remote RTSP stream source and sending the appropriate media track to other Endpoints.

Limitations

Currently, only H264 streams are supported.

If the RTSP Endpoint has yet to successfully connect to the stream source, a reconnect attempt can be made, either by the endpoint itself, or by calling Membrane.RTC.Engine.Endpoint.RTSP.request_reconnect/2. Once connected, however, if RTSP signalling crashes, the endpoint WILL NOT be able to reconnect, and will shut down instead. A manual restart of the endpoint will then be needed to restore its functionality.

Note that the RTSP Endpoint is not guaranteed to work when NAT is used by either side of the connection. By default, the endpoint will attempt to create client-side NAT binding by sending an empty datagram from client to source, after the completion of RTSP setup. This behaviour may be disabled by setting the option :pierce_nat to false.
