This change seems correct, in the sense it should not break anything, though I
don't see that well the link with encoder/decoders. I'm currently working on
implement such a decoder (my current target being Exynos) and the solution I
was to use it to have two v4l2object.

Micheal Olbrich (from Pengutronix) seems to have chosen the same solution for
the V4l2Filter element. The proposed added internal API so far is
gst_v4l_clone() to create a v4l2object reusing the file descriptor. This ensure
that each object handles one queue. Let me know what you think of this, and
you're intention, we might be able to collaborate on this.
