Question

How would i go about playing music using a discord bot from Youtube without downloading the song as a file?

I\'ve already had a look at the included music bot in the

Answer 1

To play music without downloading it, simply use this code into your play function :

ydl_opts = {'format': 'bestaudio'}
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    info = ydl.extract_info(video_link, download=False)
    URL = info['formats'][0]['url']
voice = get(self.bot.voice_clients, guild=ctx.guild)
voice.play(discord.FFmpegPCMAudio(URL))

Here is what each line is used for :

• ydl_opts = {'format': 'bestaudio'} : get the best possible audio
  
• with youtube_dl.YoutubeDL(ydl_opts) as ydl: : initialize youtube-dl
  
• info = ydl.extract_info(video_link, download=False) : get a dictionary, named info, containing all the video information (title, duration, uploader, description, ...)
  
• URL = info['formats'][0]['url'] : get the URL which leads to the audio file of the video
  
• voice = get(self.bot.voice_clients, guild=ctx.guild) : initialize a new audio player
  
• voice.play(discord.FFmpegPCMAudio(URL)) : play the right music

However, Playing audio from an URL without downloading it causes a known issue explained here
To fix it, just add a variable, for instance, FFMPEG_OPTIONS which will contain options for FFMPEG:

FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}

Once you've created the variable, you just have to add one argument to the FFmpegPCMAudio method:

voice.play(discord.FFmpegPCMAudio(URL, **FFMPEG_OPTIONS))
