import cv2cap = cv2.VideoCapture(0)fourcc = cv2.VideoWriter_fourcc(*'XVID')# fps = cap.get(cv2.CAP_PROP_FPS)size = (int(cap.get(cv2.CAP_PROP_FRAME_WIDTH)), int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT)))out = cv2.VideoWriter('camera_test.avi', fourcc,10.0, size)while True:    ret, frame = cap.read()    # 横向翻转    frame = cv2.flip(frame, 1)    out.write(frame)    # 在图像上显示 Press Q to save and quit    cv2.putText(frame,                "Press Q to save and quit",                (10, 30), cv2.FONT_HERSHEY_SIMPLEX, 0.8,                (0, 255, 0), 2)    cv2.imshow('frame', frame)    if cv2.waitKey(1) & 0xFF == ord('q'):        breakcap.release()out.release()cv2.destroyAllWindows()

注：若生成的视频显示无法打开，size改用size = (int(cap.get(cv2.CAP_PROP_FRAME_WIDTH)), int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT)))而不是自己设置数值；以及编码方式fourcc换成

video_FourCC = cv2.VideoWriter_fourcc('M', 'J', 'P', 'G')等试一下。
