question - novice questions getting my Reolink camera to work:

[duffjay]

I suspect this is a really simple mistake on my part - due to my very limited understanding of working with APIs.

I changed your test program slightly to look at the general api. I can login, get information but I can't get an image. It looks like something is wrong with my Request object.

My setup is super simple. Computer and camera on are on the same PoE switch. The camera is an RLC-420-5MP.

python test_reolink.py

oops - seems I don't know Github either. I meant to add information, not close

It's strange that the OpenCV VideoCapture function doesn't return subsequent frames, maybe the method you are using to display the frames retrieved aren't updating?

Don't worry, this repository is still quite experimental and a lot might be broken.
I can't test this right now, could you try checkout branch dev-1.0 and see if you can use the snap API?

Inside the folder where you cloned this repository:
git checkout dev-1.0
