but when i try this

vs.stop()

the camera doesn't stop and the variable vs show this value :

<imutils.video.webcamvideostream.WebcamVideoStream instance at 0x7f2c40e75b00>

Answer 1

imutils actually uses cv2.VideoCapture() to initialize stream, but didn't release it in stop.

vs.stream.release() shall work.

I've created pull request in imutils github repo :) https://github.com/jrosebr1/imutils/pull/81/files

Answer 2

vs.stream.release() didn't work for me.

vs.stream.stream.release() worked perfectly.

Answer 3

Imutils build using OpenCV, so we need to use release() to release the webcam. I have tried stop() earlier, then I realized and used release() and it is working fine for me.

vs = VideoStream(src=0).start() ## To launch the cam
vs.stream.release() # To release the camera
