hi,
i am trying to use this code in window, but how can i resize the screenshot window?
Now it will work.
import numpy as np
import cv2
from PIL import ImageGrab
fourcc = cv2.VideoWriter_fourcc('X','V','I','D') #you can use other codecs as well.
out = cv2.VideoWriter('output.avi', fourcc, 8, (500,490))
while(True):
img = ImageGrab.grab()
img_np = np.array(img)
#frame = cv2.cvtColor(img_np, cv2.COLOR_BGR2GRAY)
out.write(img_np)
cv2.imshow("frame", img_np)
key = cv2.waitKey(1)
if key == 27:
break
vid.release()
cv2.destroyAllWindows()
can we thread it, stream live ? please?

Hi,
The output.avi that is generated is only 6kb and no video is getting saved. (Python 3 and Intellij)
