Doing that from playbin might be a bit involving programatically.
What's the purpose here ? For debugging purpose, I usually trace that
information using:

  GST_DEBUG="GST_SCHEDULING:5" gst-launch-1.0 ...

This will trace GstBuffer and it's attached data (everything that can
be serialized, except the data of course) every time a buffer reaches a
sink pad.
