如何用yt-dlp Python代码跳过播放列表中的私有视频？

用yt-dlp库编写Python脚本下载YouTube播放列表时，遇到无访问权限的私有视频会触发报错，导致流程中断。已尝试配置rejecttitle、ignore-errors等选项，也查阅了yt-dlp的YoutubeDL.py文档，但问题仍未解决，寻求跳过这类私有视频的可行方案。

问题核心在于：你调用extract_info时使用的是默认YoutubeDL()实例，该实例未配置ignoreerrors=True，导致提取私有视频信息时直接抛出异常，后续的下载环节根本没机会触发错误跳过逻辑。

修改方案如下：

1. 先定义完整的ydl_opts配置，再基于该配置创建YoutubeDL实例，统一用这个实例处理信息提取和下载
2. 直接传入播放列表URL让yt-dlp自动遍历处理，无需手动拆分视频链接

修改后的核心代码片段：

def run():
    while True:
        video_url = input("\n请输入YouTube视频/播放列表链接: ")
        
        ydl_opts = {
            'format': 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/bestvideo+bestaudio/best',
            'download_archive': 'downloaded_songs.txt',
            'windowsfilenames': True,
            'outtmpl': data + '/%(title)s.%(ext)s',
            'writesubtitles': True,
            'subtitleslangs': ['en', '-live_chat'],
            'writethumbnail': True,
            'embedthumbnail': True,
            'abort_on_unavailable_fragments': False,
            'ignoreerrors': True,  # 关键配置，必须在实例化时传入
            'verbose': True,
            'postprocessors': [
                {'key': 'FFmpegMetadata', 'add_metadata': True},
                {'key': 'FFmpegEmbedSubtitle'},
                {'key': 'EmbedThumbnail', 'already_have_thumbnail': True},
            ]
        }

        with yb.YoutubeDL(ydl_opts) as ydl:
            # 用同一个实例处理信息提取和下载，download=True直接触发下载
            video_info = ydl.extract_info(url=video_url, download=True)
            
            # 区分单个视频和播放列表的情况
            if 'entries' in video_info:
                # 播放列表：遍历所有成功下载的条目
                for entry in video_info['entries']:
                    if entry:
                        print("\n下载完成... {}".format(entry['title']))
            else:
                # 单个视频：直接输出标题
                print("\n下载完成... {}".format(video_info['title']))
            
            thumbnail_path()
            clear()

额外说明：

• ignoreerrors=True的作用是让yt-dlp遇到错误时跳过当前条目、继续处理后续内容，必须在创建YoutubeDL实例时传入才会生效
• 原代码中先调用无配置的extract_info，这一步就会因私有视频报错中断，后续的下载配置完全没发挥作用
• 直接传入播放列表URL时，yt-dlp会自动遍历所有视频，错误条目会被自动跳过，无需手动处理
