Hi,
I watch lectures live on zoom.
The lectures are slow so I speed them up and sometimes pause and re-listen to a section I do not understand.
This require me to record the lecture.
My computer is basically stuck while I do it and I wonder if I can do it in the background, say on 'screen 4' and work on 'screen 1'.

To be able to do other stuff on the computer I would like the recording to be a 'encapsulated' process i.e. no interference from outside nor anything escaping form the inside.
I mean I would like no sound from my what I'm doing to enter the recording (e.g. listening to music) and no sound to escape the recording (e.g. destroying my music listening).

Is this possible?
How would you set it up?

I have heard about jack is that possible with jack?
Currently I use obs studio and simple screen recorder.

Fortunately for me, I've not had to deal with this, but I have used Jack. Jack is an audio tool that you can use to pipe audio from one application to another (think "jack" as in "audio jack"). It might possibly useful for managing the audio so that it goes directly from the Zoom output into the recording application, bypassing your speakers.

A web search for "record lecture linux" will turn up a number of articles and tutorials you might find helpful.

I see no reason why you couldn't record on one workspace while doing something else on another workspace, but it is likely wise not to attempt to play music while recording a screencast, but I've never tested that. I would suggesting testing your setup with some YouTube videos or streaming video, say from tubi.tv or some other streaming service.

Just a few thoughts off the top of my head.

I think jack will work.
Just have to learn how to do it.

You can use Kazam for the recording
