I could not connect google colab to the camera on macbook air M1, I do use the code they provice but still not figure out device.

I tried provided code by google colab or change videocapture(1) to other value. Finally I only can upload video and finish the lab. i also check some youtube video,asked question there,from their video, it seem like they also work on mac, but i asked and nobody could solve this problem.
