使用youtube-dl搜索Youtube视频

Question

我正在尝试构建一个Discord音乐机器人，需要使用用户提供的关键词搜索YouTube。目前我知道如何通过URL播放。

       loop = loop or asyncio.get_event_loop()
       data = await loop.run_in_executor( None, lambda: ytdl.extract_info(url, download=not stream))
       if "entries" in data:
            data = data["entries"][0]

        filename = data["url"] if stream else ytdl.prepare_filename(data)
        return cls(discord.FFmpegPCMAudio(filename, **ffmpeg_options), data=data)

Youtube_DL有一个名为extract_info的方法，您可以使用它。您无需提供链接，只需传递ytsearch:args即可：

from requests import get
from youtube_dl import YoutubeDL

YDL_OPTIONS = {'format': 'bestaudio', 'noplaylist':'True'}

def search(arg):
    with YoutubeDL(YDL_OPTIONS) as ydl:
        try:
            get(arg) 
        except:
            video = ydl.extract_info(f"ytsearch:{arg}", download=False)['entries'][0]
        else:
            video = ydl.extract_info(arg, download=False)

    return video

这个函数有几个重要的事项:

• It works with both words and urls
• If you make a youtube search, the output will be a list a dictionnaries. In this case, it will return the first result
• It will return a dictionnary containing the following informations:

  video_infos = search("30 sec video")
  
  #Doesn't contain all the data, some keys are not very important
  cleared_data = {
      'channel': video['uploader'],
      'channel_url': video['uploader_url'],
      'title': video['title'],
      'description': video['description'],
      'video_url': video['webpage_url'],
      'duration': video['duration'], #in seconds
      'upload_date': video['upload_data'], #YYYYDDMM
      'thumbnail': video['thumbnail'],
      'audio_source': video['formats'][0]['url'],
      'view_count': video['view_count'],
      'like_count': video['like_count'],
      'dislike_count': video['dislike_count'],
  }

您是否安装了正确的软件包？这个答案也可能已经过时了，因为youtube-dl的最新版本是2021年发布的。 - MrSpaar

Answer 2

我不确定使用youtube-dl通过关键词搜索YouTube URL是否好用。你可能应该看一下youtube-search。
