streaming – obs-studio: connect to an existing dlive.tv stream and record?

Can I somehow connect obs-studio to an existing dlive.tv stream, and record and/or re-stream the stream? Using the same URL as one would for watching dlive.tv from a browser?

I’m a total beginner when it comes to obs-studio (linux), so please bear with me if this is a foolish question.

The main problem I’m trying to solve is to keep a rolling log of the last 5-10-20 min (say) of the dlive.tv stream so that I can save it if something interesting is observed. Think: security camera. Yes, it would be easier if the owner of the security camera did this job, but, no, he does not want to do it and tells me I can do it myself. But I need to figure out how :).
