What steps are needed to stream RTSP from FFmpeg?

Streaming UDP is not a problem, but as I want to stream to mobile devices which can natively read RTSP streams, I c

FWIW, I was able to setup a local RTSP server for testing purposes using simple-rtsp-server and ffmpeg following these steps:

1. Create a configuration file for the RTSP server called rtsp-simple-server.yml with this single line:

   protocols: [tcp]
   

2. Start the RTSP server as a Docker container:

   $ docker run --rm -it -v $PWD/rtsp-simple-server.yml:/rtsp-simple-server.yml -p 8554:8554 aler9/rtsp-simple-server
   

3. Use ffmpeg to stream a video file (looping forever) to the server:

   $ ffmpeg -re -stream_loop -1 -i test.mp4 -f rtsp -rtsp_transport tcp rtsp://localhost:8554/live.stream
   

Once you have that running you can use ffplay to view the stream:

$ ffplay -rtsp_transport tcp rtsp://localhost:8554/live.stream

Note that simple-rtsp-server can also handle UDP streams (i.s.o. TCP) but that's tricky running the server as a Docker container.
