How to access cameras with opencv

[mawriyo]

I have a basic script to try and access a camera. I tried using opencvs cv2.VideoCapture() but have tried the devices i see on ls /dev. I get /dev/video0, /dev/video1, /dev/video32, /dev/video33. I also tried to use gstreamer to access these cameras to no result.

I installed a v4l2-utils to see my devices to which returns when I use '''vl2-ctl --list-devices''' which returns

"msm_vidc_vdec ():
/dev/video32
/dev/video33
/dev/v4l-subdev2
/dev/v4l-subdev3
/dev/v4l-subdev4
/dev/v4l-subdev5
/dev/v4l-subdev6
/dev/v4l-subdev7"

Any idea how I can use the cameras that come with the kit to be used in basic CV programming?

There are many examples in our SDK code base of how to consume that data. Here is a good place to look for each of our services: https://gitlab.com/voxl-public/voxl-sdk/services
