"Can't get stream control: Error:'%s'."%uvc_error_codes[status] #57

Closed valvador92 closed 5 years ago

image

raise InitError("Can't get stream control: Error:'%s'."%uvc_error_codes[status]) uvc.InitError

I don't understand why I have this error when I run example.py I have done the same installation on my Laptop, example.py is working with the integrated webcam, but as soon I want to plug the Headset, I have this error.

I think that the error is coming from this command: frame = cap.get_frame_robust()

It looks like you need to modify example.py. The example is trying to cap at resolution (640, 480) at 15 fps. However, if you see the list of available modes printed above you see that this is not an option. Please try (129, 192, 200) - or any of the other available modes - in https://github.com/pupil-labs/pyuvc/blob/master/example.py#L18.

It works with (192,192,120) for the eye cameras and (1280,720,30) for the world camera. Thank you!

Now, how to show the images in rgb? For now it is only in gray.

I can't find a command in OpenCV for that

papr commented 5 years ago

The eye cameras record in the ir light spectrum. Color values are not meaningful in that space.

valvador92 commented 5 years ago

Yeah I know. But for the World camera, how can I do it?

valvador92 commented 5 years ago

I have found the answer: it is frame.bgr to show the picture un RGB

Hi @valvador92 I will close this issue now as it seems to be resolved for you. Please re-open or comment if not.
