以下代碼是保存視頻
# coding:utf-8
import cv2
import sys
reload(sys)
sys.setdefaultencoding('utf8')
cap = cv2.VideoCapture(0)
cap.set(3,640)
cap.set(4,480)
cap.set(1, 10.0)
#此處fourcc的在MAC上有效，如果視頻保存為空，那么可以改一下這個參數試試, 也可以是-1
fourcc = cv2.cv.CV_FOURCC('m', 'p', '4', 'v')
# 第三個參數則是鏡頭快慢的，10為正常，小於10為慢鏡頭
out = cv2.VideoWriter('/opt/code/video/output2.avi', fourcc,10,(640,480))
while True:
ret,frame = cap.read()
if ret == True:
frame = cv2.flip(frame, 1)
a = out.write(frame)
cv2.imshow("frame", frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
else:
break
cap.release()
out.release()
cv2.destroyAllWindows()
以下代碼是拍照，在按q之后，保存圖片並退出。
import cv2
cap = cv2.VideoCapture(0)
while(1):
# get a frame
ret, frame = cap.read()
# show a frame
cv2.imshow("capture", frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
cv2.imwrite("/opt/code/image/fangjian2.jpeg", frame)
break
cap.release()
cv2.destroyAllWindows()
