需要画框取消注释rectangle

import cv2
import os,sys,shutil
import numpy as np
 
# open the input movie file, input the filepath as
input_filepath = sys.argv[1]
input_movie = cv2.videocapture(input_filepath)
length = int(input_movie.get(cv2.cap_prop_frame_count))
 
#设置output
output_movie = cv2.videowriter(input_filepath.replace("mp4","avi").replace("input","output"), cv2.videowriter_fourcc('d', 'i', 'v', 'x'), 25, (1280, 720))
 
# initialize some variables
frame_number = 0
 
while true:
 # grab a single frame of video
 ret, frame = input_movie.read()
 
 frame_number += 1
 
 # quit when the input video file ends
 if not ret:
  break
 
 # draw a box around the body: input the top left point(x,y) and bottom right point(x,y)
 #cv2.rectangle(frame, (left, top), (right, bottom), (0, 0, 255), 2)
 
 # write the resulting image to the output video file
 print("writing frame {} / {}".format(frame_number, length))
 output_movie.write(frame)
 
# all done!
input_movie.release()
cv2.destroyallwindows()
