How to open webcam using opencv in google colab?

it is not working and not giving any frames please help

you can’t. colab is google servers. google servers don’t have webcams attached to them.

you can find answers to this on google because this question has been asked for as long as colab exists.

again, you cannot use cv.VideoCapture on colab.

however, they came up with a mockup js/html replacement,
have a look in the ‘code-snippets’ sidebar to find copy/paste ready code for this :wink:


please, NEVER post such a sentence again, anywhere, ppl will only take you for an idiot.

it’s does not bother me what people think and thanks for the help as it is good to ask people with more knowlegde.
