I did try playbin myself before and it does give me video, however, I can't use that approach.  Do you know a way to get the pipeline for this case?  Thanks a lot.

Can you tell use why you cannot use playbin or even better playbin2. It is
supposed to work fine on embedded devices too. And if it does not for you then
it might be worth to figure that out and fix it.
