简而言之就是下载音视频的命令行工具。
安装yt-dlp
brew install yt-dlp
基本用法
yt-dlp [OPTIONS] URL [URL...]
1. 视频下载 - 基础
yt-dlp <视频URL>
eg:

这样就在当前所在文件夹下载好了这个视频，并且因为我已经brew install ffmpeg这个工具，所以下载好的音视频直接就进行了合并，这样这个视频就包含了音频在内。
我们来看看我输入命令之后的各项输出结果：
- 获取 URL 地址；
- 下载各项信息；
- 下载格式：299+251
- 开始下载：
- f299.mp4 –> 视频
- f251.webm –> 音频
- 合并音视频 –> .mkv
- 删除原始文件：
- f299.mp4 –> 视频
- f251.webm –> 音频
上边有几点需要说明下：
yt-dlp下载的音视频是分开的，我们看到一个格式：299+251，这里涉及音视频的格式，我们通过

我们完全可以根据自己的需要进行选择，比如我们可以搭配：
- 音频是m4a，对应的ID是140；
- 视频我们选一个体积较小的mp4格式的，1920x1080,对应的数字ID就是312；
那么最后我们选择格式就是：
140+312。xdl@MacBook-Air ~ % yt-dlp -f 140+312 "https://www.youtube.com/watch?v=baZ5dM_tXI4" [youtube] Extracting URL: https://www.youtube.com/watch?v=baZ5dM_tXI4 [youtube] baZ5dM_tXI4: Downloading webpage [youtube] baZ5dM_tXI4: Downloading tv client config [youtube] baZ5dM_tXI4: Downloading player 69f581a5 [youtube] baZ5dM_tXI4: Downloading tv player API JSON [youtube] baZ5dM_tXI4: Downloading ios player API JSON [youtube] baZ5dM_tXI4: Downloading m3u8 information [info] baZ5dM_tXI4: Downloading 1 format(s): 140+312 [download] Destination: 周深 - 好风起｜歌词｜无损音质 [baZ5dM_tXI4].f140.m4a [download] 100% of 4.10MiB in 00:00:02 at 1.94MiB/s [hlsnative] Downloading m3u8 manifest [hlsnative] Total fragments: 52 [download] Destination: 周深 - 好风起｜歌词｜无损音质 [baZ5dM_tXI4].f312.mp4 [download] 100% of 11.80MiB in 00:00:01 at 6.09MiB/s [Merger] Merging formats into "周深 - 好风起｜歌词｜无损音质 [baZ5dM_tXI4].mp4" Deleting original file 周深 - 好风起｜歌词｜无损音质 [baZ5dM_tXI4].f140.m4a (pass -k to keep) Deleting original file 周深 - 好风起｜歌词｜无损音质 [baZ5dM_tXI4].f312.mp4 (pass -k to keep)你当然也可以选择只下载某个格式的音频，或者视频，比如你只要m4a格式的音频，那么就是：

2. 视频下载 - 查询格式
我们整理一下上边说的格式查询的语法：
youtube -F <视频URL>
-F | --list-formats:- List available formats of each video.
3. 视频下载 - 自定义格式下载
通过-F知道了有哪些格式可供下载，下一步就可以用-f进行搭配。
youtube -f FORMAT <视频URL>
-f | --format:- Video format code. See “FORMAT SELECTION” for more details.
4. 音频下载与转换
通过上边说的-f FORMAT我们选择自己需要的音频进行下载，也可以通过-x来提取音频。
youtube -x <视频URL>
-x, --extract-audio:- Convert video files to audio-only files (requires ffmpeg and ffprobe).
我们也可以跟上格式转换参数来转换音频格式，比如：
xdl@MacBook-Air ~ % yt-dlp -x --audio-format mp3 "https://www.youtube.com/watch?v=baZ5dM_tXI4"
[youtube] Extracting URL: https://www.youtube.com/watch?v=baZ5dM_tXI4

Deleting original file 周深 - 好风起｜歌词｜无损音质 [baZ5dM_tXI4].webm (pass -k to keep)
上边这个例子就是下载最好的音频格式，并且将最终的格式转换成我要的mp3格式。
当然也可以跟上质量参数。
--audio-quality QUALITY:- specify ffmpeg audio quality to use when converting the audio with -x. Insert a value between 0 (best) and 10 (worst) for VBR or a specific bitrate like 128K (default 5)
5. 播放列表相关
yt-dlp <播放列表URL>
eg:
yt-dlp "https://www.youtube.com/playlist?list=PLKbGySt1xT03OW5tX38OPDElIUe6-XPIt"
当然你可以跟上各种控制参数，比如格式啊之类的。
我再举个例子，注意这个例子的URL链接和上一个是不同的，上一个是纯播放列表。
yt-dlp --yes-playlist "https://www.youtube.com/watch?v=7wHZ9IldjR8&list=PLKbGySt1xT03OW5tX38OPDElIUe6-XPIt"
这个链接指向了一个播放列表中的一个具体的视频，跟上--yes-playlist表示我还是要全部列表中的视频。
yt-dlp --no-playlist "https://www.youtube.com/watch?v=7wHZ9IldjR8&list=PLKbGySt1xT03OW5tX38OPDElIUe6-XPIt"
同样，但是跟上--no-playlist表示我只要这个视频，不要列表中的其他视频，即使链接可以指向播放列表。
选择播放列表中的某几个：
-I, --playlist-items ITEM_SPEC:- Comma separated playlist_index of the items to download. You can specify a range using “[START]:[STOP][:STEP]”. For backward compatibility, START-STOP is also supported. Use negative indices to count from the right and negative STEP to download in reverse order. E.g. “-I 1:3,7,-5::2” used on a playlist of size 15 will download the items at index 1,2,3,7,11,13,15
xdl@MacBook-Air ~ % yt-dlp -x -I 4:6,12 "https://www.youtube.com/watch?v=7wHZ9IldjR8&list=PLKbGySt1xT03OW5tX38OPDElIUe6-XPIt"
