以下代码是保存视频
# 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) #此处fourcc的在MAC上有效,如果视频保存为空,那么可以改一下这个参数试试, 也可以是-1 fourcc = cv2.cv.CV_FOURCC('m', 'p', '4', 'v') # 第三个参数则是镜头快慢的,10为正常,小于10为慢镜头 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()
以下代码是拍照,在按q之后,保存图片并退出。
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()
