读取摄像头内容,然后保存一段十秒钟的视频。
import cv2 cameraCapture = cv2.VideoCapture(0) fps = 30 # an assumption size = (int(cameraCapture.get(cv2.cv.CV_CAP_PROP_FRAME_WIDTH)),int(cameraCapture.get(cv2.cv.CV_CAP_PROP_FRAME_HEIGHT))) videoWriter = cv2.VideoWriter('MyOutputVid.avi', cv2.cv.CV_FOURCC('I','4','2','0'), fps, size) success, frame = cameraCapture.read() numFramesRemaining = 10 * fps - 1 while success and numFramesRemaining > 0: videoWriter.write(frame) success, frame = cameraCapture.read() numFramesRemaining -= 1
