Fixed, wrong connection

0xPr0xy commented 3 years ago

how did you solve this?

PvdGulik commented 3 years ago

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

0xPr0xy commented 3 years ago

@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!
