解决方案

你的程序不会像这样工作。声明为的文档状态FFmpegPCMAudio

class discord.FFmpegPCMAudio(source, *, executable='ffmpeg', pipe=False, stderr=None, before_options=None, options=None)

您将字典video作为source. 但是，FFmpegPCMAudio()不能缓冲视频流。它只能播放本地保存的文件，这些文件通过FFmpeg. source必须是文件的链接，就像你在参数中一样executable。既然你有download = False争论

info = ydl.extract_info(url, download=False)

您只是提取视频信息，而不是实际下载它。如果没有文件，则无法播放。

要解决您的问题，您需要下载 youtube 视频的音频，并将文件FFmpegPCMAudio()路径指定为source
