I haven't a clue how to use OBS with Firefox, or any other web browser. What I need to know, of course, is how to get Firefox to run in such a way that the `obs-mac-virtualcam` module is also running inside the Firefox main process. What help I can find isn't written from that point of view.

I haven't a clue how to use OBS with Firefox, or any other web browser. What I need to know, of course, is how to get Firefox to run in such a way that the `obs-mac-virtualcam` module is also running inside the Firefox main process. What help I can find isn't written from that point of view. Edit: Found the answer. 1) Open the OBS installer and copy its app (OBS Studio) to the `/Applications` directory, then run it. 2) Allow it to install the extra stuff it needs. 3) Leave it running. No other setup is needed. 4) (Re)start Firefox. From this point, doing `image list` in `lldb` includes `/Library/CoreMediaIO/Plug-Ins/DAL/obs-mac-virtualcam.plugin/Contents/MacOS/obs-mac-virtualcam`. I suppose that gets loaded automatically with the `CoreMediaIO` framework. And the demo apps from comment #2 will find an "OBS Virtual Camera". You don't even need to have a real camera installed.
