youtube-dl 只提取播放列表信息

Question

ydl = youtube_dl.YoutubeDL()
with ydl:
    r = ydl.extract_info("myplaylist", download=False)  # don't download, much faster

print(r['uploader'],r['title'],r['thumbnail'])

代码输出是这样的

[youtube:playlist] Downloading playlist playlistidhere - add --no-playlist to just download video videoid
[youtube:playlist] playlistidhere: Downloading webpage
[download] Downloading playlist: playlistnamehere
[youtube:playlist] playlist Spotlight On: June Recap: Downloading 39 videos

但我只想要 youtube 播放列表信息，我的问题是如何获取播放列表的上传器、缩略图、所有视频缩略图、视频标题、播放列表标题等。

您可以将youtube_dl\xef\xbc\x8cinvoke youtube_dl 导入为 ydl 并设置 download=False，这是一个示例

\n\n

download = False \nydl_opts = {\n    \'outtmpl\': fileName,     // output filename\n    \'writesubtitles\': True,\n    \'format\': \'mp4\',\n    \'writethumbnail\': True\n}\n\nwith youtube_dl.YoutubeDL(ydl_opts) as ydl:\n    ie_result = ydl.extract_info(url, download)\n

\n\n

您可以使用https://github.com/daomanlet/freesea/blob/master/sites/downloader.py

\n\n

import youtube_dl\nfrom freesea import Download\nsrv = DownloadService()\nie_result = srv.downloadVideo(\'https://www.youtube.com/channel/UCaO6VoaYJv4kS-TQO_M-N_g\',\'./\',False)\nprint(ie_result)\n

\n\n

你会看到 ie_result 仅包含信息
