If we look at uvch264src (c920), it reads a single stream from the
camera and produces 2. It's implementing a bin, with a slave v4l2src
and a demuxer afterward.

My recent abuse of GstBaseSrc, and the reason I concluded that a GstBin
is just a better idea was about wrapping Android Camera HAL 3. We
hacked GstBaseSrc to make it possible, but the end result was a
nightmare.
