Requirements

How to install using pip

pip install obsws-python

How to Use

By default the clients connect with parameters:

You may override these parameters by storing them in a toml config file or passing them as keyword arguments.

Order of precedence: keyword arguments then config file then default values.

config file

A valid config.toml might look like this:

[connection]
host = "localhost"
port = 4455
password = "mystrongpass"

It should be placed in your user home directory.

Otherwise:

Example __main__.py:

import obsws_python as obs

# pass conn info if not in config.toml
cl = obs.ReqClient(host='localhost', port=4455, password='mystrongpass', timeout=3)

# Toggle the mute state of your Mic input
cl.toggle_input_mute('Mic/Aux')

Requests

Method names for requests match the API calls but snake cased. If a successful call is made with the Request client and the response is expected to contain fields then a response object will be returned. You may then access the response fields as class attributes. They will be snake cased.

example:

# load conn info from config.toml
cl = obs.ReqClient()

# GetVersion, returns a response object
resp = cl.get_version()
# Access it's field as an attribute
print(f"OBS Version: {resp.obs_version}")


# SetCurrentProgramScene
cl.set_current_program_scene("BRB")

send(param, data=None, raw=False)

If you prefer to work with the JSON data directly the {ReqClient}.send() method accepts an argument, raw. If set to True the raw response data will be returned, instead of a response object.

example:

resp = cl_req.send("GetVersion", raw=True)

print(f"response data: {resp}")

For a full list of requests refer to Requests

Events

When registering a callback function use the name of the expected API event in snake case form, prepended with "on_".

example:

# load conn info from config.toml
cl = obs.EventClient()

def on_scene_created(data):
    ...

# SceneCreated
cl.callback.register(on_scene_created)

def on_input_mute_state_changed(data):
    ...

# InputMuteStateChanged
cl.callback.register(on_input_mute_state_changed)

# returns a list of currently registered events
print(cl.callback.get())

# You may also deregister a callback
cl.callback.deregister(on_input_mute_state_changed)

register(fns) and deregister(fns) accept both single functions and lists of functions.

For a full list of events refer to Events

Attributes

For both request responses and event data you may inspect the available attributes using attrs().

example:

resp = cl.get_version()
print(resp.attrs())

def on_scene_created(data):
    print(data.attrs())

Errors

Logging

If you want to see the raw messages simply set log level to DEBUG

example:

import obsws_python as obs
import logging


logging.basicConfig(level=logging.DEBUG)
...

Tests

First install development dependencies:

pip install -e .['dev']

To run all tests:

pytest -v
