Hi!
Ok. This time I try to check hardware and not need image processing. I
uncomment this line in script:

This is virtual channel 1 output from the imx6-mipi-csi2 receiver. Make
sure the imx219 is indeed transmitting on virtual channel 1.

What is the format on /dev/video3 ? Please provide output from 'v4l2-ctl
-d3 -V'

Another error, but some result. I think fakesink must got Bayer format
(as specific /dev/null for v4l2).
Can you try simply:
localhost ~ # v4l2-ctl -d3 --stream-mmap
and let me know if you receive frames.

# media-ctl -l "'ipu1_csi1':2 -> 'ipu1_csi1 capture':0[1]" #

The IPUv3 IC hardware does not support processing Bayer formats.
Those can only be written straight to RAM using this path.
