A small project to write a scene to a file. This file can be read by something like the Advanced Scene Switcher plugin for OBS.

If you find this useful, please donate to me :)

• Python3.6+
• pywin32 (Only if on Windows)

• Linux
• Windows

(macOS will probably never be supported because of the weird API for getting a window title.)

1. Download the repo as zip.
2. Run screen_daemon.py.
3. Edit the now generated config file to your liking.
4. Run screen_daemon.py ( for real this time ;) )
5. Configure OBS to switch to the scene by reading the file. (You can use the Advanced Scene Switcher for this)
6. Done!

The default config file screens.json is as follows:

{
    "start_scene": "Coding",
    "unknown_app_scene": "Privacy",
    "delay_time": 300,                            
    "window_class": {
        "google-chrome": {
            "strict_match": true,
            "scene": "Research"
        },
        "jetbrains": {
            "strict_match": false,
            "scene": "Coding"
        }
    },
    "window_name": {
        "whatsapp": {
            "strict_match": false,
            "scene": "Privacy"
        }
    },
    "desktop_name": {
        "1": {
            "strict_match": false,
            "scene": "Privacy"
        }
    }
}

start_scene (int): When you boot screen_daemon.py, it sets the scene to your default scene.

unknown_app_scene (str): If an app is not listed under window_class or window_name, it will default to this. Set to null if you don't want this auto-switch.

delay_time (int): The time between scanning the active window. Defaults to 300 ms.

window_class: List of window classes (WM_CLASS with xprop, executable name for Windows).
| - strict_match (bool): Strict matching means the window class / executable has to be EXACTLY the same. Off for checking close resemblance instead.
|
| - scene (str): The OBS scene name to switch to when this window_class becomes active.

window_name: Same as window class, but matches against window title.

desktop_name: Same as window class, but matches against workspace names.
