My original comment is down below. However, I was wrong. It is possible in 2.8 - as in the video instructions, if you click ALT-E, you should see a menu for extruding along individual faces. Also, you can find the same options in the "Face" menu at the top of the window.

Mark, I'm having the same problem. I did notice though that if I select two different faces that are not connected by adjacent edges that I can get the faces to extrude along their own face normals
1. I selected "normal" from transform orientation at top of 2.8 window
2. I selected"individual origin" from pivot point
3. while extruding, you may have to click the axis key to change the direction (x,y,z)
Anyway, this showed a little bit of hope.
