OBS script that can execute CLI commands when a scene is activated.

The original version of this script was written by marklagendijk in Lua. marklagendijk's version of the script called the CLI command from Lua using os.execute(scene_command) which opens a command window that stayed open while the command is run. This got very annoying when screen captuing and switching scenes, because the command prompt would pop-up and be visible on stream!

To solve this, I rewrote the script in python and instead call the CLI command using subprocess.run(scene_command, shell=True). My version of the script functions identically to the original, except for silent execution (ie. no window pop-up) and a more detailed description.

Happy obs-ing!
