Important is to read the error message that this pipeline produces
because it tells you what is wrong:

Some snippet from the debug log (it queries the supported formats):
gstv4l2object.c:1032:gst_v4l2_object_fill_format_list:<v4l2src0> got 4
format(s):

So the camera supports only 4 formats: YU12, YV12, BGR3 and RGB3 all of
them emulated.
Since you are trying to make it produce UYVY with the capsfilter, this
will fail, as the error message suggests. It does not call VIDEOC_S_FMT
because the query of the formats revealed that UYVY is not supported.
