pipeline dump

Oddly this doesn't seem to introduce test failures, unless playbin3 is enabled.

In some tests such as media/track/in-band/track-in-band-kate-ogg-cues-added-once.html the combiner pads can receive multiple caps events describing the same stream, that's not good because then new vtt encoders are added to the combiner and remain unlinked. See attached pipeline dump.
