有没有办法用Python在视频开头添加一张图片？

import cv2

# 加载视频
video_path = "video.mp4"
cap = cv2.VideoCapture(video_path)

# 加载图片
image_path = "image.jpg"
image = cv2.imread(image_path)

# 获取视频的帧率、宽度和高度
fps = cap.get(cv2.CAP_PROP_FPS)
width = int(cap.get(cv2.CAP_PROP_FRAME_WIDTH))
height = int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT))

# 创建视频编写器
output_path = "output.mp4"
fourcc = cv2.VideoWriter_fourcc(*"mp4v")
out = cv2.VideoWriter(output_path, fourcc, fps, (width, height))

# 将图片添加到视频开头
out.write(image)

# 逐帧读取视频并写入输出视频
while cap.isOpened():
    ret, frame = cap.read()
    if not ret:
        break
    out.write(frame)

# 释放资源
cap.release()
out.release()
cv2.destroyAllWindows()
