StreamPlayer “after” function isn't being called

Question

I am creating a discord bot that can play music but I'm a bit stuck because when the bot finishes playing music is should leave the current voice channel. However this isn't happening, instead my after function vc.disconnect isn't being called at all though I've followed the instructions on the FAQ page.

vc = await bot.join_voice_channel(ctx.message.author.voice_channel)
player = await vc.create_ytdl_player(arg.split(' ')[1], after=vc.disconnect)
player.start()

Answer 1

The problem is that vc.disconnect is a coroutine. You need to handle it differently, as the after call doesn't await the coroutine since the voice player is just a Thread .

According to the docs , this is how it should be handled:

def my_after():
    coro = vc.disconnect()
    fut = asyncio.run_coroutine_threadsafe(coro, client.loop)
    try:
        fut.result()
    except:
        pass

player = await voice.create_ytdl_player(url, after=my_after)
player.start()

Also as noted by the docs , the following warning:

Warning

This function is only part of 3.5.1+ and 3.4.4+. If you are not using these Python versions then use discord.compat. .

Meaning that if you're running Python 3.4.0-3.4.3 or 3.5.0, your my_after needs to be changed to this:

def my_after():
    from discord.compat import run_coroutine_threadsafe
    coro = vc.disconnect()
    fut = run_coroutine_threadsafe(coro, client.loop)
    try:
        fut.result()
    except:
        pass
