Not able to save video using cv2.VideoWriter(...) on Ubuntu 16.04
After running below code I am getting a "output.avi" file of 5.7KB.Nothing is recorded from camera.
# https://docs.opencv.org/3.0-beta/doc/py_tutorials/py_gui/py_video_display/py_video_display.html
import numpy as np
import cv2
cap = cv2.VideoCapture(0)
# Define the codec and create VideoWriter object
fourcc = cv2.VideoWriter_fourcc(*'XVID')
out = cv2.VideoWriter('output.avi',fourcc, 20.0, (640,480))
while(cap.isOpened()):
ret, frame = cap.read()
if ret==True:
frame = cv2.flip(frame,0)
# write the flipped frame
out.write(frame)
cv2.imshow('frame',frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
else:
break
# Release everything if job is finished
cap.release()
out.release()
cv2.destroyAllWindows()
Please help.
Try to swap w and h in video writer constructor:
(480, 640)
. Are you sure the frame returned by video capture has this size?@prashant - Maybe you should answer your own question. I learned something, so I'd rate it up.
