这是@Neabfi的答案的更新答案
import time
import cv2
import numpy as np
from mss import mss
mon = {'top': 160, 'left': 160, 'width': 200, 'height': 200}
with mss() as sct:
# mon = sct.monitors[0]
while True:
last_time = time.time()
img = sct.grab(mon)
print('fps: {0}'.format(1 / (time.time()-last_time)))
cv2.imw('test', np.array(img))
if cv2.waitKey(25) & 0xFF == ord('q'):
cv2.destroyAllWindows()
break
并保存到mp4视频
import time
import cv2
import numpy as np
from mss import mss
def record(name):
with mss() as sct:
# mon = {'top': 160, 'left': 160, 'width': 200, 'height': 200}
mon = sct.monitors[0]
name = name + '.mp4'
fourcc = cv2.VideoWriter_fourcc(*'mp4v')
desired_fps = 30.0
out = cv2.VideoWriter(name, fourcc, desired_fps,
(mon['width'], mon['height']))
last_time = 0
while True:
img = sct.grab(mon)
# cv2.imshow('test', np.array(img))
if time.time() - last_time > 1./desired_fps:
last_time = time.time()
destRGB = cv2.cvtColor(np.array(img), cv2.COLOR_BGRA2BGR)
out.write(destRGB)
if cv2.waitKey(25) & 0xFF == ord('q'):
cv2.destroyAllWindows()
break
record("Video")
