my camera located on /dev/video10

[alexsalex]

Fixed, wrong connection

[0xPr0xy]

how did you solve this?

[PvdGulik]

Yes, I also want to know. This exactly the problem I'm facing for days!
Please @alexsalex, how did you solve this?

[0xPr0xy]

@PvdGulik For me it was indeed a wrong connection. Even if 'vcgencmd get_camera' shows connected camera, this is not actually checking the camera works, just that it detects the connected hardware. You should verify that making picture from command line using 'raspistill -v -o picture.jpg' works if both commands succeed hkcam should also work!
