obs-cli VS pdfdraw

Leverage OBS' API and use https://github.com/muesli/obs-cli or something similar.

Your WM/DE can respond to global hotkeys though, so you can presumably set some to issue obs-cli commands.

The only tip I'd have would be for Wayland users who suffer from not having global shortcuts work with OBS: obs-cli with obs-websocket have you covered. Set a keyboard shortcut or Stream Deck button (using streamdeck-ui) to execute an obs-cli command and you're done.

There is an obs-cli application that you can use to pass commands to OBS. Last time I tried it it wasn't fully compatible with the last OBS version, but check it out none the less, maybe they updated it.

I am on the same boat as you, though for not professional reason, but personal. Ive been using ubuntu for 3 years, off and on before that. I got a streamdeck about two years ago when I started streaming for fun and the streamdeck + OBS intergration is lack luster. There are projects that are helping to fill the gap (obs-cli and Streamdeck UI) but they lack a lot of the features offered from the official elgato control panel.

So with a little manual setup, anything that can be done from command line can be done with global shortcuts, e.g. using obs-cli for OBS shortcuts: https://i.imgur.com/NZOg68p.png

So I came up with kind of a hacky solution with a Powershell script. It disables the sceneitem in OBS with obs-cli, restarts the entire USB port with devcon64, and then reenables the OBS sceneitem.

In the meantime, you could probably use something like obs-cli, set up scripts to start and stop recording, and bind them to hotkeys in KWin.

For the moment, I'm thinking about using ahk to detect the mouse position, which would then speak to obs-cli which would switch scenes.
