Camera example is not working

koture

Hi~

I am testing Variscite's DART-MX8M-PLUS with CMOS-MIPI-OV5640. (Yocto with QT)
I try to use 2x MIPI-CSI cameras simultaneously.

gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-raw,width=1280,height=720 ! autovideosink sync=false
==> It works fine

But The below example doesn't works.(error : The camera service is missing)

Looking forward to hearing.
Thank you in advance.

Best Regards,
Jayden
