In this situation, are you obliged to stop your vehicle to allow a pedestrian to cross the road?

When approaching a pedestrian crossing, a driver is required to give way not only to a pedestrian on the crossing, but also to one entering it. The pedestrian visible in the recording is standing at the edge of the carriageway, clearly signalling their intention to cross.
