OBS Websocket Control?

ianmdesign · May 5, 2023, 2:00am

Wondering if this exists anywhere in the wild, OBS Websocket Control starts a stream when a print is started and stops when the print has concluded, or maybe it's set via the temperature of the hot end. I know of the plugins that do RTMP forwarding for the MPEG stream cam, but I added more in my OBS with overlays that'd I'd like to remain included while automating streams for when I print.

Does OBS have any form of API/webhook based control? If so you could use the webhooks plugin, or even the built in event manager to run system commands if you can figure out a command line/bash script approach to control OBS.

I don't believe webhooks are supported. From what I've seen, it's only web sockets

well, found a simple client that uses python. you could use it potentially, here's an example.

github.com

IRLToolkit/simpleobsws/blob/8e5b58d8f2bcf4a3121a9911253b38e9e43e0ff0/samples/sample_request.py

import logging
logging.basicConfig(level=logging.DEBUG)
import asyncio
import simpleobsws

parameters = simpleobsws.IdentificationParameters(ignoreNonFatalRequestChecks = False) # Create an IdentificationParameters object (optional for connecting)

ws = simpleobsws.WebSocketClient(url = 'ws://localhost:4444', password = 'test', identification_parameters = parameters) # Every possible argument has been passed, but none are required. See lib code for defaults.

async def make_request():
    await ws.connect() # Make the connection to obs-websocket
    await ws.wait_until_identified() # Wait for the identification handshake to complete

    request = simpleobsws.Request('GetVersion') # Build a Request object

    ret = await ws.call(request) # Perform the request
    if ret.ok(): # Check if the request succeeded
        print("Request succeeded! Response data: {}".format(ret.responseData))

    await ws.disconnect() # Disconnect from the websocket server cleanly

you'd have to dig through the protocol docs to get the right request I suppose, but it's a starting point.

also found a command line version that might work too.
