上面代码报错AttributeError: 'cv2.VideoCapture' object has no attribute 'write'

非常抱歉，我写错了代码。在解密过程中，我们不需要写入视频，只需要读取像素并提取隐藏的文本。这里是修正后的代码：

import cv2

def extract_text_from_video(video_path):
    video = cv2.VideoCapture(video_path)
    frames = int(video.get(cv2.CAP_PROP_FRAME_COUNT))

    extracted_text = ""
    current_bit = ""
    bit_count = 0

    for _ in range(frames):
        ret, frame = video.read()
        if not ret:
            break

        pixel = frame[0, 0]  # 仅提取首个像素点的LSB

        # 提取像素点的最低有效位
        lsb = bin(pixel[-1])[-1]

        current_bit += lsb
        bit_count += 1

        if bit_count == 8:  # 当累计8个比特位时，转换为一个字符
            if current_bit == "00000000":  # 结束标志为8个0
                break
            extracted_text += chr(int(current_bit, 2))
            current_bit = ""
            bit_count = 0

    video.release()

    return extracted_text

# 使用示例
video_file = "hidden_video.avi"  # 隐写信息嵌入的视频文件路径
hidden_text = extract_text_from_video(video_file)
print("提取的隐藏文本：", hidden_text)

再次感谢你的指正，希望这次能够正常运行！如果还有其他问题，请随时提问。
