him i'm trying to use my go pro for video input for the example but it doesn't seem to want to work. this is the error that i keep getting.

Though so was gonna run it on my scrap laptop on my vm

Make sure your camera is mapped to /dev/video0. You can test by running ffplay /dev/video0
Sometimes it is on another device (video2,4,6,8 etc...)

[HarryHayek]

Yes that works and I know it's video0 because my other image processing code uses it. But having trouble actually incorporating hailo chip

hey @HarryHayek did you get out of this problem?

[HarryHayek]

@dixitm624 nope but I think I understand what i might need to do to get it working since I got it working with a pi cam so I know that the chip works and that the gopro works. Just have to create a new halo model probably
