You intend to drive into the gate. Are you obliged to give the right of way to these pedestrians?

Yes. When approaching a marked pedestrian crossing (sign D-6), a driver is obliged to exercise special caution and give way to a pedestrian entering the crossing. The pedestrians seen in the video are directly at the crossing and clearly intend to step onto it, so you must stop and allow them to cross the roadway safely. This obligation arises from Art. 26 para. 1 of the Road Traffic Act.
