【问题描述】：

我正在尝试在 python 中使用 yt-dlp 下载视频。

ydl_opts = {'format': 'bv+ba/b'}
with YoutubeDL(ydl_opts) as ydl:
     ydl.download('https://www.reddit.com/r/cats/comments/re37dn/weve_been_feeding_this_stray_for_several_years/')

但我在日志中遇到 FFmpeg 错误

FFmpeg 通过 pip 安装并添加到 PATH 中。

【问题讨论】：

ffmpeg 不会通过 pip 安装。它不是 python 模块。关于如何在此处进行 dl 的说明：ffmpeg.org/download.html
我已经通过官网下载并添加了FFpeg到PATH，遗憾的是没有解决问题。 @mechinal_meat
好的，但您至少收到了不同的错误消息吗？你能从你的命令行成功调用 ffmpeg 吗？
是的，ffmpeg 在命令行中运行良好

标签： python ffmpeg

【解决方案1】：

同样的错误信息，然后我意识到我的 yt-dlp 是通过 snap 安装的。所以我只是从 snap 中删除它，然后从 pip 安装它。现在一切正常。
