Does the "Stop" sign visible in the presented situation indicate the mandatory place to stop the vehicle before entering the intersection?

In the video you are approaching a junction in a town; on the right, on a post, there is sign B-20 "STOP", and on the roadway beyond the pedestrian crossing you can see a faded word STOP and a barely visible stop line. The visible STOP sign does not mark the exact place where you are required to stop. The answer is: no.

The Regulation on road signs and signals states that sign B-20 means a ban on entering the junction without stopping before the priority road and an obligation to give way to drivers travelling on that road; you should stop at the place designated for this purpose, and if there is none - at a place where the driver can make sure that they will not obstruct traffic on the priority road. The place for stopping is marked by road marking P-12 "mandatory stop line - STOP", and not by the vertical sign itself. It is the markings, not the sign on the post, that show the place to stop; if they were completely worn away, you would stop where you can see the intersecting road in both directions - beyond the pedestrian crossing, just before the edge of that road, but so that you do not stick out onto the priority roadway. Stopping at the post with the sign would not show you anything.

Legal basis: § 21 para. 1 and 2 and § 89 para. 1 and 4 of the Regulation on road signs and signals
