python - 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
我的问题是如何获得播放列表的上传器、缩略图、所有视频缩略图、视频标题、播放列表标题等。

Answer 1

您可以导入 youtube_dl ，调用 youtube_dl 为 ydl 并设置 download=False，这里是一个例子

download = False 
ydl_opts = {
    'outtmpl': fileName,     // output filename
    'writesubtitles': True,
    'format': 'mp4',
    'writethumbnail': True
}

with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    ie_result = ydl.extract_info(url, download)

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

import youtube_dl
from freesea import Download
srv = DownloadService()
ie_result = srv.downloadVideo('https://www.youtube.com/channel/UCaO6VoaYJv4kS-TQO_M-N_g','./',False)
print(ie_result)

你会看到 ie_result 只包含信息
