This one is wrong; format needed to be YUY2. That way, it attempts to
start video streaming, but no data go through, and I don't really know
how to debug that.


export GST_DEBUG=libcamera*:7
export GST_PLUGIN_PATH=$(pwd)/build/src/gstreamer

gst-launch-1.0 libcamerasrc camera-name=/base/i2c-csi/rear-camera at 4c !
video/x-raw,width=1280,height=720,format=YUY2,colorimetry=bt709,framerate=30/1
! filesink location=/tmp/delme.unk ; ls -al /tmp/delme.unk
