Would someone have an idea how to workaround that?

mobian at mobian:~/g/tui/pp$ time  gst-launch-1.0 v4l2src device=/dev/video2 num-buffers=15  \! video/x-raw,width=1280,height=720,format=UYVY,framerate=15/1 \! fakesink

I tried various permutations, but could not get past "Device '/dev/video2' does not sup\
port 2:0:0:0 colorimetry" message with newer gstreamer.

I know libcamerasrc might be able to workaround that, but I have
trouble getting that to work, too :-(.
