You can also use yavta [#f2]_ command to do same thing as above:
.. code-block:: none
yavta --data-prefix -Bcapture-mplane -c10 -n5 -I -s2592x1944 \
--file=frame-#.out-f NV12 /dev/video5 & \

--file=/tmp/frame-in.cio2 -f IPU3_SGRBG10 /dev/video4
where /dev/video4, /dev/video5, /dev/video6 and /dev/video7 devices point to
input, output, viewfinder and 3A statistics video nodes respectively.
