使用Youtube-Dl批量下载YouTube播放列表至对应文件夹遇问题

Hey there! Let's break down what's causing those errors and get your batch playlist downloads sorted out properly.

The Root of the Problem #

Your original command has a critical mistake: you didn't use the -o (output) flag to specify your file naming/folder structure template. Instead, you dumped the template directly into the command line, which youtube-dl interpreted as invalid URLs—hence all those "not a valid URL" errors you're seeing.

The Correct Command #

To batch download multiple playlists and automatically organize each into its own named folder, use this command (adjust for Windows CMD vs. Unix shells as needed):

For Unix/Linux/macOS (Bash/Zsh):

youtube-dl --extract-audio --audio-format mp3 -i -o '%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s' https://www.youtube.com/playlist?list=PLuE_hO-7ktGpcYuoeE9o8w-2MWEkKu5zK [第二个播放列表链接] [第三个播放列表链接]

For Windows Command Prompt:

Windows CMD doesn't handle single quotes well, so swap them for double quotes:

youtube-dl --extract-audio --audio-format mp3 -i -o "%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s" https://www.youtube.com/playlist?list=PLuE_hO-7ktGpcYuoeE9o8w-2MWEkKu5zK [第二个播放列表链接] [第三个播放列表链接]

What Each Part Does #

• -o "%(playlist)s/...": This is the key flag. %(playlist)s gets replaced with the actual name of the YouTube playlist, and youtube-dl will automatically create this folder if it doesn't exist. The rest of the template (%(playlist_index)s - %(title)s.%(ext)s) names each audio file with its position in the playlist and the video title.
• --extract-audio --audio-format mp3: Extracts the audio stream from each video and converts it to MP3 (your original working parameters, which are correct here).
• -i: Ignores individual download errors so the process keeps going through the rest of the playlists/files.
• The final arguments are all the playlist URLs you want to download—just separate them with spaces.

Bonus: Batch Download from a Text File #

If you have a ton of playlists, it's easier to list each URL on a new line in a text file (e.g., playlists.txt), then use the -a flag to read from it:

# Windows example
youtube-dl --extract-audio --audio-format mp3 -i -o "%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s" -a playlists.txt

That should resolve the errors and get your playlists organizing themselves automatically!
