如何在python中显示csv中的视频文本

import pandas as pd

df = pd.read_csv('video.csv')

pip install opencv-python

import cv2

video_path = 'video.mp4'
cap = cv2.VideoCapture(video_path)

while(cap.isOpened()):
    ret, frame = cap.read()
    
    if ret == True:
        cv2.imshow('Video', frame)
        
        # 按下'q'键退出循环
        if cv2.waitKey(25) & 0xFF == ord('q'):
            break
    else:
        break

cap.release()
cv2.destroyAllWindows()

for index, row in df.iterrows():
    video_path = row['video_path']
    text = row['text']
    
    cap = cv2.VideoCapture(video_path)
    
    while(cap.isOpened()):
        ret, frame = cap.read()
        
        if ret == True:
            cv2.putText(frame, text, (50, 50), cv2.FONT_HERSHEY_SIMPLEX, 1, (255, 255, 255), 2)
            cv2.imshow('Video', frame)
            
            # 按下'q'键退出循环
            if cv2.waitKey(25) & 0xFF == ord('q'):
                break
        else:
            break
    
    cap.release()
    cv2.destroyAllWindows()
