使用CV2实现视频的镜像/对称效果

import cv2
import numpy as np

video_capture = cv2.VideoCapture('input_video.mp4')
width = int(video_capture.get(3))
height = int(video_capture.get(4))
fourcc = cv2.VideoWriter_fourcc(*'XVID')
video_writer = cv2.VideoWriter('output_video.mp4', fourcc, 30, (width, height))

while True:
    ret, frame = video_capture.read()
    
    if not ret:
        break
    
    # 镜像处理
    mirrored_frame = cv2.flip(frame, 1)
    
    # 写入镜像后的帧到输出视频文件
    video_writer.write(mirrored_frame)
    
    cv2.imshow('Mirror Video', mirrored_frame)
    
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

video_capture.release()
video_writer.release()
cv2.destroyAllWindows()
