This python script allows capturing of windows in OBS that have a dynamic title. This is useful for capturing WhatsApp or other programs where you want to capture a window based on a regular expression.

This script only works on Windows.

OBS requires you to install a compatible version of Python.

After installing Python, you will also need pywin32 which can be downloaded from here.

To install other dependencies:

pip install -r requirements.txt

1. Create a scene and a Window Capture source. The program/window this captures is not important at this point.
2. Add the script to OBS.
3. Choose the name of the source you wish to update.
4. Specify an executable (case insensitive) - e.g. "whatsapp.exe".
5. Provide a regular expression for the window title - e.g. ".*video call".

Whenever the scene is changed, a check is done to see if the selected source matches the window that is configured.
