help with bassline transcription?

starting @ 00:12. i think im hearing root-5th-octave, the octave possibly even being a slide, then back to the 5th, then a repeat of that entire motif. << laptop speakers aren't really letting me hear everything i need to hear but I'd appreciate some input.

so, a quick listen confirms 1-5-8-1-5-8-1-5-8-8-5-8-6-5-4-8-11-4-8-11-4-8-11-11-8-10-(not sure of the last few notes) key of A[sup]b[/sup], so

A[sup]b[/sup]-E[sup]b[/sup]-A[sup]b[/sup]'-A[sup]b[/sup]-E[sup]b[/sup]-A[sup]b[/sup]'-A[sup]b[/sup]-E[sup]b[/sup]-A[sup]b[/sup]'-A[sup]b[/sup]'-E[sup]b[/sup]-A[sup]b[/sup]'-F-E[sup]b[/sup]-D[sup]b[/sup]-A[sup]b[/sup]'-D[sup]b[/sup]'-D[sup]b[/sup]-A[sup]b[/sup]'-D[sup]b[/sup]'-D[sup]b[/sup]-A[sup]b[/sup]'-D[sup]b[/sup]'-D[sup]b[/sup]'-A[sup]b[/sup]'-D[sup]b[/sup]'

Not sure if this is played on a fretless, but there is a little sliding going on, but it is more the standard sort of Latin bass (first 3 notes of the 3-2 clave pattern) playing root-5th-octave
