Record Video From a Webcam using OpenCV

  • cv2.VideoWriter( filename, fourcc, fps, frameSize )

The parameters are :

  • filename: Specifies the name of the output video file.
  • fourcc: (for recording) Defining the codec
  • fps: Defined frame rate of the output video stream
  • frameSize: Size of the video frames
In [ ]:
import cv2
capture=cv2.VideoCapture(0)

cod = cv2.VideoWriter_fourcc(*'XVID')
out = cv2.VideoWriter('out.avi',cod,20.0,(640,480))

while True:
    ret,frame=capture.read()
    gray=cv2.cvtColor(frame,cv2.COLOR_BGR2GRAY)
    cv2.imshow('Gray',gray)
    cv2.imshow('Color',frame)
    out.write(frame)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
capture.release()
cv2.destroyAllWindows()

Also, a video is recorded and saved with the name ‘out.avi’ in the same file location with predefined frame rate i.e 20fps and frame size (640×480)
