Create local server using FFMPEG (ADVANCED)
Install FFMPEG to create the server and receive a streaming (one camera at a time).
FFMPEG can be obtained on Ubuntu with:
sudo apt-get install ffmpeg
Using the following command you can create a local server on which the robot will try to send the streaming.
ffplay 'srt://<LOCAL_IP>:<PORT>?streamid=publish/?streamid=<ROBOT_ID>/<CAMERA>&mode=listener'
Replace LOCAL_IP with the IP visible on the same network by the robot, PORT with the port it is going to use, ROBOT_ID with the ID of the robot in question and CAMERA with the name of the camera you expect to receive from the robot.

Usage example
Enable streaming of 'nav_top' camera:
self.cameras: CamerasController = await self.enable_controller('cameras')
port, protocol, path = await self.cameras.enable_streaming(camera_name='nav_top')
