From the output of your v4l2-ctl, UYVY is not supported by your
hardware. Have you tried with YU12 or YV12, or letting GStreamer
negotiate by omitting the format ?

Note that all formats with your camera are emulated, which mean there is
software conversion happening in libv4l2. I'm just mentioning, in case
you have some performance issues.
