Cannot start example #2

Open azlekov opened 1 month ago

azlekov commented 1 month ago

In a newly created project I have added the dependency and copy uvc_example.dart, but when I start it, it gives me:

Syncing files to device macOS...

I'm using Mac Studio M1

What I'm doing wrong?

And a question, is there a way to capture image from UVC camera with this library?

Thanks for trying out uvc. It does not support image capture at this time.

As for the error, I am not sure why it cannot find the libusb library. I will have to investigate this more.
