如何在Python中文件超过一定大小时中止youtube-dl下载

import os
import youtube_dl

def progress_hook(d):
    if d['status'] == 'downloading':
        # 获取已下载的文件大小
        downloaded_size = d.get('downloaded_bytes', 0)
        # 获取视频文件的总大小
        total_size = d.get('total_bytes', 0)
        # 设置文件大小限制（以字节为单位）
        size_limit = 100000000  # 100MB
        if total_size > size_limit:
            # 如果文件大小超过限制，则中止下载
            raise youtube_dl.utils.DownloadError('File size exceeds limit')

def download_video(url):
    ydl_opts = {
        'progress_hooks': [progress_hook],
        'outtmpl': '%(title)s.%(ext)s'  # 设置下载文件的命名格式
    }
    with youtube_dl.YoutubeDL(ydl_opts) as ydl:
        ydl.download([url])

try:
    download_video('https://www.youtube.com/watch?v=video_id')
except youtube_dl.utils.DownloadError as e:
    print('Download aborted:', str(e))
