Creating a dedicated per frame metadata stream?

Here is what I'd like to do:
I have a *live* source that is capturing video. What I'd like to do is
create a multistream file, say an MLV, where one stream is the actually
video while another is a data stream essentially of per fram metadata
(think timestamps and other sensory data at the time of capture).
I know vendors like GoPro do this: They basically create I think a
complimentary audio stream that is actually metadata but I'm not exactly
sure how. I've also seen other smaller third-paty do something similar with
video overlay.
Has anyone done this before using GStreamer? If so, can you give me a
little guidance on how that would work? Is this a custom plugin or are
there exiting primitives I could exploit?
Thanks!
