Basic music with playlist support on Rewrite

music.py

"""
Please understand Music bots are complex, and that even this basic example can be daunting to a beginner.

For this reason it's highly advised you familiarize yourself with discord.py, python and asyncio, BEFORE
you attempt to write a music bot.

This example makes use of: Python 3.6

For a more basic voice example please read:
    https://github.com/Rapptz/discord.py/blob/rewrite/examples/basic_voice.py

This is a very basic playlist example, which allows per guild playback of unique queues.
The commands implement very basic logic for basic usage. But allow for expansion. It would be advisable to implement
your own permissions and usage logic for commands.

e.g You might like to implement a vote before skipping the song or only allow admins to stop the player.

Music bots require lots of work, and tuning. Goodluck.
If you find any bugs feel free to ping me on discord. @Eviee#0666

How would I modify this to play local files?

I wouldn't use this code if I were you, It is good it shows the basics of Discord Music Clients, but in reality this script is jack
YouTube links/gates have expiry times so if you try to play anything after a set amount of 25-30 seconds the gate expiry's

You do realise it handles that?

Although even though it does handle it. I would suggest using Lavalink. If you can handle a few Linux commands and have a VPS to run it on you will have a much better time with running a music bot. You can also checkout my lib, WaveLink, which is a powerful wrapper around Lavalink for discord.py.

I’m using lavalink, but after a while I get NodeNotFound error

how can i add a loop command?

If its loop as in replay Queue. I would suggest just setting queue position to 0

How would you add a loop command for a single song?

Don't clear the queue, and repeat it. even if its 1 song, you can add it to queue. OR
You can play the last-played song at the end of each song, If its repeated it will play the same song.

I've been trying to code it where it doesn't clear the queue, and it repeats it instead. However, I have been unable to do this. Can you please tell me specifically the code that would be required to do this?

Mate, I'm just saying how you can do it. I'm not gonna now do a full tutorial just for you so you can copy & paste it.
I have enough stuff to do.

Pls help
Command raised an exception: RuntimeError: PyNaCl library needed in order to ise voice

Pls help
Command raised an exception: RuntimeError: PyNaCl library needed in order to ise voice

mate it literally tells you what you need, Install PyNaCI

it might be caused due to something in get_player i think

can you do a loop command?

Please make a loop command :)

Hi, I'm having this error
TypeError: 'coroutine' object is not iterable
in the line 358
fmt = '\n'.join(f'**{_["title"]}**' for _ in upcoming)

I tried to search why this happens but most sources I've found say that it must have await outside the function but if I'm not wrong it already is in here, any help is welcome :)

edit.
Nvm apparently any having @bot.command which also iterates list brake the thing. I solved it by encasing those commands in a class and making them @commands.command.

I added bot = commands.Bot(prefix='!') and did bot.run with my token at the bottom but when I tried to use the commands I get "no such command" error. What could be causing that?

fsr it gives me a error: ERROR: No video formats found
can someone help me?

Hello, Im using your code which is amazing very smart by the way. Im having some troubles where it brings up that play is not an attribute, i have the error code posted below this. This only happens once and while and its normally in the middle of a song. If someone could please help that would be great.

Hi, your code works perfectly, fast and easy to use. I'm only having a problem with playing playlists. If I link a playlist with the play command it only queue the first song. Looking at the console, it returns this error:

What URL are you passing? There are some types of YouTube playlists that aren’t collections of songs and ytdl doesn’t recognize them as a list to iterate through. I fixed this by being more selective about the urls I passed into it.

I'm testing with this one:
https://youtube.com/playlist?list=PLov8ST38VcFSYhPl56Ggba12RFA0mjueG
i tried with hidden and public @moviebrain

@davidesidoti I tested it in my fork of music.py and everything loads except the second song in your playlist Jonas Blue. That song appears to be blocked in the USA and is why YTDL is throwing the error. Give music py a minute or two to ingest the whole 91 other songs and it’ll start playing without a problem (or, rather, did for me)

@moviebrain After waiting a little bit it actually load but queue only the first song for me. I am in Europe, could it be that all the other songs are blocked here?

@davidesidoti this gets off topic for this python program, but you can pass the playlist url to YouTube-dl and list the stream formats for every playlist item. If the song is unavailable from where ever you are it’ll output “Error: Video Unavailable” instead of the webm/mp4/etc info by using the following command in a terminal:

youtube-dl —list-formats {playlist url}

Or you can click each of those individual videos and see if YouTube gets mad.

@moviebrain I'll try, thank you for your help 😄

Added a command with bot.add_command(Music.play_), but when I try to use the command, I get

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: TypeError: Music.play_() missing 1 required positional argument: 'ctx'

Any ideas?

Maybe try passing (ctx) as an argument to the function. That's what the error suggests atleast.

Anyone else have the bot skip to the next song in queue at the middle of the song?

Anyone else have the bot skip to the next song in queue at the middle of the song?

I am experiencing that also, I have no idea how to fix it. For me it cuts out partially through at roughly the same spot in the song and its different depending on the song, and it does not continue to the next song in the queue.

I believe this behavior is because YouTube has changed how streaming links expire, and the mechanism by which the stream links are regathered in this code no longer work due to this aggressive new policy. I’ve modified the behavior to prefer downloads and play “locally” with ffmpeg transformer instead of streaming links until it’s discovered why streaming can’t be regathered or refreshed.

Thanks for posting this! This helped me build my music bot cog
