如何使用python播放opencv中特定时间戳的视频文件？

import cv2

video_path = "视频文件路径"
cap = cv2.VideoCapture(video_path)

timestamp = 10  # 设置特定时间戳，单位为秒
frame_rate = cap.get(cv2.CAP_PROP_FPS)  # 获取视频帧率
frame_to_skip = int(timestamp * frame_rate)  # 计算需要跳过的帧数
cap.set(cv2.CAP_PROP_POS_FRAMES, frame_to_skip)  # 设置视频的当前帧为特定时间戳对应的帧

while cap.isOpened():
    ret, frame = cap.read()
    if not ret:
        break
    cv2.imshow("Video", frame)
    if cv2.waitKey(1) & 0xFF == ord('q'):  # 按下 'q' 键退出循环
        break

cap.release()
cv2.destroyAllWindows()
