Sewer scope material

I did a sewer scope in Agoura California, And I’m having a very difficult time figuring out what material this is. My fear is that it might be Orangeburg because of the ripples, but most of the pipe is smooth enough making me think it’s ABS It could be a liner, but typically you’ll see writing on the side of the pipe. Then I see small portions of white so maybe it’s PVC.

Any advice you can give I’d greatly appreciate.

What material was the clean out riser made out of?

(A post must be at least 10 characters long, so that’s why I’m typing this parentheses)

Then that is your sewer material.

Appreciate your help, but how do we know it was not added at a later date? I see ABS clean outs attached to cast iron pipes all the time.

You are the one that is video scoping the pipe. Do you see a transition coupling installed?
