--- Comment #1 from Nicolas Dufresne (stormer) <nicolas at ndufresne.ca> ---
That preference is intentional. I hope that you won't be surprised that this
patch will be rejected.

1) The pro is simplicity. If you provide patch that way, please don't limit
this to v4l2src. We have helper to add properties everywhere it make sense.

2) GstVideoFormat is not a macro, but a C enumeration. What you propose just
don't fit. It would also not work with anything that exists.

3) These are called fields. I think such field would only be understood by V4L
elements, which we normally try to avoid.

Few questions, are you going to work on this ? Can you explain better how your
two drivers ended up in this situation ? I would have expected this to never be
an issue for IP from the same SoC
