It errors out with not-negotiated it seems, which indicates a problem
with the caps negotiation.

Well, that's not very promising. Can you make a debug log like this?
GST_DEBUG=*v4l*:6 gst-launch-1.0 v4l2src num-buffers=1 ! fakesink
Note that you may need to compile v4l2src from -good against
libvideo4linux(-devel) in case the camera only offers formats that are
not handled natively in GStreamer and that need converting.
