Using obs-websocket

A web client and frontend made by t2t2 (compatible with tablets and other touch interfaces) is available here : http://t2t2.github.io/obs-tablet-remote/

It is highly recommended to protect obs-websocket with a password against unauthorized control. To do this, open the "Websocket server settings" dialog under OBS' "Tools" menu. In the settings dialogs, you can enable or disable authentication and set a password for it.

Possible use cases

  • Remote control OBS from a phone or tablet on the same local network
  • Change your stream overlay/graphics based on the current scene (like the AGDQ overlay does)
  • Automate scene switching with a third-party program (e.g. : auto-pilot, foot pedal, ...)

For developers

The server is a typical Websockets server running by default on port 4444 (the port number can be changed in the Settings dialog). The protocol understood by the server is documented in PROTOCOL.md.
