I know that using * after a substring works as a “starts with” operator (similar to the SQL clause LIKE 'substring%'). Is there a similar operator for “ends with” or “contains,” comparable to the SQL clauses LIKE '%substring' or LIKE '%substring%', respectively?

Hi I am planing on doing a screen recording since all my attempts to catch a rtmps stream where in vain.
So I was wondering if there is any possibility for a site to detect that I am using a screen recording software (sorry if the questions sounds silly but I am not a tech savvy). Also, I would like to know if I need any special kind of hardware to do this, I am using Macbook 2012 with a basic Intel Graphics 4000 and 16 GB of RAM. Would this be enough?
