In this situation, are you approaching a crossroad with a one-way side road to the right?

At the end of the recording, on the right side of the road, the warning sign A-6d "junction of a one-way road from the right" is visible. This sign warns of an intersection where the junction of a subordinate road (indicated by a thinner line on the sign) is on the right side and it is a one-way road. According to § 5 para. 1 of the Regulation on road signs and signals, the thickness of the lines on the sign indicates the right of way.
