python - youtube-dl 在 pycharm 中无法按预期工作

问题描述

我已经制作了这段代码来仅从 youtube 上的 url 下载音频，但某些链接不起作用


video_url = "https://www.youtube.com/watch?v=5yijULf4Hko" #  doesn't work for example
#video_url = "https://www.youtube.com/watch?v=gKK3Y6iDk_Q" #  does work

filename = "song.mp3"

options = {
    'format': 'bestaudio/best',
    'keepvideo': False,
    'outtmpl': filename,
    'postprocessors': [{
            'key': 'FFmpegExtractAudio',
            'preferredcodec': 'mp3',
            'preferredquality': '251',
        }],
    }

with youtube_dl.YoutubeDL(options) as ydl:
    ydl.download([video_url])

当我尝试使用第一个链接时，程序输出：

[youtube] 5yijULf4Hko: Downloading webpage

During handling of the above exception, another exception occurred:

我正在使用最新版本的 pycharm (2020.2.1) 已经尝试更新 youtube-dl 我尝试在命令提示符下下载并成功下载了音频文件 youtube-dl -f 251 https://www.youtube.com/watch?v=5yijULf4Hko

起初以为这是版权问题，但它也不适用于一些我确定没有版权的网址

解决方案

我找到了解决它的方法，但感觉我做错了，我改变了这一行：

with youtube_dl.YoutubeDL(options) as ydl:
    ydl.download([video_url])

至

import os


try:
    with youtube_dl.YoutubeDL(options) as ydl:
        ydl.download([video_url])
except:
    os.system(f"""youtube-dl -o "song.%(ext)s" --extract-audio -x --audio-format mp3 {video_url}""")

我只是使用了在程序的命令提示符下工作的命令，但我无法让 python 库像这样工作，如果有人知道如何正确解决这个问题，我将不胜感激
