The websocket server runs on port 4444 and the protocol is based on the OBSRemote protocol (including authentication) with some additions specific to OBS Studio. The stream class template provides asynchronous and blocking message-oriented functionality necessary for clients and servers to utilize the WebSocket protocol. For asynchronous operations, the application must ensure that they are are all performed within the same implicit or explicit strand. The basic flows When the button is pushed (or the Inject node sends a timestamp), a payload is sent through the change node, converted from a JSON object to a string, then sent to the WebSocket Out node. Protocol allows for a persistent, full-duplex communication between a client and remote host.

For more real time interaction, or real time transfer or streaming of data, HTTP and REST aren’t the best suited protocol and abstraction combination. This is where Sockets and WebSockets shine. WebSockets vs REST: A Comparison of Performance. The overhead of opening and closing connections is very real. Stream market updates using WebSocket streaming.

On successful execution, a WebSocket connection to the url will be established and audio will start streaming.wss is the only supported protocol. The url does not support query string parameters.
