In this situation, if you go straight, do you have the right of way over the vehicle approaching from the right?

In the initial phase of the video (frames 1-3), the A-6b 'intersection with a subordinate road on the right' warning sign is visible on the right side. This sign informs you that you are on a priority road. This means you have priority over any vehicle emerging from the crossroad, including the blue car visible later approaching from the right, according to § 5 para. 2 pt. 1 of the Regulation on road signs and signals.
