Run your own live streaming server

Daily Keyframes provides a way to live stream video or audio calls with low latency, and has created a ready-made Docker image to make it easy to run one's own streaming server. To set up the server, one needs a publicly accessible IP address, Docker, and optionally ngrok. The `nginx-rtmp-docker` project is used for convenience, and the process of setting up the server involves running a command in the terminal to start the Docker container. Once the server is running, one can stream to it using OBS or the `startLiveStreaming()` API, and access the stream at specific URLs depending on whether the user has set up ngrok.
