request-websocket.py - a helper command to send requests to OBS Studio
SYNOPSIS
request-websocket.py [request_type data] ...
request-websocket.py --help
DESCRIPTION
This script will take pairs of request_type and data and send each pair to OBS Studio.
The last pair can skip data if you don't need to send any data.
request_type
This is a request-type supported by obs-websocket protocol or 'sleep'.
If request_type is 'sleep', data has to be a non-negative number to sleep in seconds.
Otherwise, the request-type will be directly send to obs-websocket.
data
The data is a JSON text. The data can be an empty string if you don't need to send any data.
EXAMPLES
request-websocket.py GetVersion
request-websocket.py SetPreviewScene '{"scene-name": "Scene"}'
request-websocket.py SetCurrentScene '{"scene-name": "Scene1"}' sleep 10 SetCurrentScene '{"scene-name": "Scene2"}'
