[ZhongyuMa]

how to use video file as a frame source instead of a camera?

 # Video source from webcam or video file.
    video_src = 0
    cam = cv2.VideoCapture(video_src)

change video_src to the path of the video file. Check https://docs.opencv.org/3.0-beta/doc/py_tutorials/py_gui/py_video_display/py_video_display.html for more info.

Same problem here, so... finally I can't just use the camera when run the program?

@iamzhangyunlu can you post the error message here?

@iamzhangyunlu can you post the error message here?

No error message, and the camera light is on，but no visual interface.

[yinguobing]

How about video file?

[iamzhangyunlu]

Video file can run

[yinguobing]

Please make sure the camera is working properly, using something like:

import cv2

cap = cv2.VideoCapture(0)
while True:
    _, frame = cap.read()
    cv2.imshow("Preview", frame)
    cv2.waitKey(30)

[iamzhangyunlu]

cap = cv2.VideoCapture(0) while True: _, frame = cap.read() cv2.imshow("Preview", frame) cv2.waitKey(30)

Excellent! But face in the cam can not be recognized now

[yinguobing]

It's hard to tell. Have you modified the code in any way?

I will try again, thank you👍

[hmuha03]

I am also having the same issue. I didn't modify the code.

OpenCV: 4.1.0 Python: 3.6.0

Video works fine after commenting out print(tm.getTimeSec()/tm.count())

For camera the debugger goes till
facebox = box_queue.get()

After this statement it doesn't do anything.

Also, my webcam is working fine with the following code.

while True: _, frame = cap.read() cv2.imshow("Preview", frame) cv2.waitKey(30)

[LuanBaviloni]

Same here. The problem is at:

facebox = box_queue.get()

[yinguobing]

Looks like we are having a issue with multiprocessing on macOS. I will look into this later.

Actually I'm using Ubuntu 18.04, with Python 3.7.4

也有可能是camera 的端口被占了，此时的capture()中的数字需要往后调整1，2,3，都可以试试。

Hi, same problem here: stuck in line facebox = box_queue.get() using macOS. Any progress on this topic?
