Youtube-dl API: 'h' 不是有效的 URL

Question

大家好，我正在使用 youtube-dl 下载通用音频 MP4 文件，但我想使用 ffmpeg 将 mp4 文件转换为 mp3，我可以在 ytdl post 处理选项中执行此操作吗？

正如我上面提到的，该文件不是 YouTube 视频，它是一个通用的 link 我还将粘贴我的代码和我遇到的错误

import youtube_dl
ydl_opts = {
    'format': 'bestaudio/best',
    'postprocessors': [{
        'key': 'FFmpegExtractAudio',
        'preferredcodec': 'mp3',
        'preferredquality': '192',
    }],
}


url = "https://aac.saavncdn.com/372/16275cb323c0a13951a08c27660f0500_320.mp4"
with youtube_dl.YoutubeDL(ydl_opts) as ydl:

    ydl.download(url)

但是我收到一条错误消息说 'h' 不是有效的 URL

任何时候当你看到一个错误，你给它一个字符串，而 API 只看到一个字符，你需要怀疑 API 实际上需要一个列表或元组。这里就是这种情况。做：

    ydl.download((url,))

Youtube-dl API: 'h' 不是有效的 URL

Youtube-dl API: 'h' is not a valid URL

python

youtube-dl
