Variable, thanks, now I got it!
(defun screen-record-switch ()
(interactive)
(cond ((and (process-live-p video-recording-process)
(buffer-live-p (get-buffer video-recording-buffer)))
(switch-to-buffer video-recording-buffer))
(t (rcd-message "There is no recording available."))))
video-recording-buffer ➜ "*Screen Recording*"
It is of course a bit confusing, some functions accept BUFFER-OR-NAME 🤔
and some only OBJECT 📝.
Now I got it, thanks much! Solved! 😊
