Python webcam record

I want to create a webcam streaming app that records webcam stream for, say about 30 seconds, and save it as myFile.wmv. Now To get live camera feed I know this code :-

import cv2
import numpy as np
c = cv2.VideoCapture(0)

while(1):
    _,f = c.read()
    cv2.imshow('e2',f)
    if cv2.waitKey(5)==27:
        break
cv2.destroyAllWindows()

But I have no idea off how to record for a given number of seconds and save it as a file in its current directory,

Please someone point me to the right direction

Thanks

  • ABOUT TIME

    Why do not use the python time function? In particular time.time() Look at this answer about time in python

    NB OpenCV should have (or had) its own timer but I can not tell you for sure if it works in current versions.
