Put the screw for the eccentric, marked S on the eccentric into the slot (or V on the shaft)once you get it pushed to the left where it belongs & tighten the screw should get it feeding again.

Thanks! Although I don't see anything marked "S", there are 2 distinct screws on the eccentric that can be screwed into the slot. The first one I tried resulted in no stepping at all, but the other one seems to work, as it is now stepping, and the stitch length adjustment even seems to be within the correct range too. 

However, now the bobbin hook is not catching the thread, so I assume that something went out of alignment. Any hints/suggestions on what/how to adjust would be much appreciated.

You will want to get the correct set screw screwed into the groove in the shaft, as there are timing adjustments downstream of this that will be affected if this is incorrect.

Typically there are two set screws, 90 degrees apart on the shaft. I can see the shaft has a groove in it. One of the set screws is meant to be tightened into the shaft groove (this screw often has a rounded tip that fits well into the groove). The other set screw is meant to be tightened against the regular face of the shaft. (this screw will likely have a flat tip)

After you get that sorted, I would check that the clutch safety is engaged.

And send us another video zoomed in on the needle and bobbin area, slow motion turn with the handwheel like four seconds or so per revolution.

I think the clutch is kicked out,take the bobbin out,try pushing on the stitch length button ,turn the handwheel backwards  until it goes into the slot,while holding the button down push the handwheel backwards until  you hear a click or until it just won't turn anymore.This "should" get the clutch re-engaged.
