How can I use youtube_dl with a discord.py bot? - discord.py

Question

I am making a music discord bot using python and I am having an issue where I download the video as a .webm file but then ffmpeg is not able to read this file and throws the error below.
ERROR: WARNING: unable to obtain file audio codec with ffprobe
2022-11-30 20:57:06 ERROR discord.ext.commands.bot Ignoring exception in command play

Here is my current code. It breaks between line 30 and 35.
import discord
from discord.ext import commands
import youtube_dl
import os
client = commands.Bot(command_prefix="q!", intents=discord.Intents.all())
#client.command()
async def play(ctx, url: str):
# song_there = os.path.isfile("song.mp3")
# try:
# if song_there:
# os.remove("song.mp3")
# except PermissionError:
# await ctx.send("Wait for the current playing music to end or use the 'stop' command")
# return
voiceChannel = discord.utils.get(ctx.guild.voice_channels, name='General')
await voiceChannel.connect()
voice = discord.utils.get(client.voice_clients, guild=ctx.guild)
ydl_opts = {
'format': 'bestaudio/best',
'postprocessors': [{
'key': 'FFmpegExtractAudio',
'preferredcodec': 'mp3',
'preferredquality': '192',
}],
}
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
ydl.download([url])
for file in os.listdir("./"):
if file.endswith(".mp3"):
os.rename(file, "song.mp3")
voice.play(discord.FFmpegPCMAudio("song.mp3"))
#client.command()
async def leave(ctx):
voice = discord.utils.get(client.voice_clients, guild=ctx.guild)
if voice.is_connected():
await voice.disconnect()
else:
await ctx.send("The bot is not connected to a voice channel.")
#client.command()
async def pause(ctx):
voice = discord.utils.get(client.voice_clients, guild=ctx.guild)
if voice.is_playing():
voice.pause()
else:
await ctx.send("Currently no audio is playing.")
#client.command()
async def resume(ctx):
voice = discord.utils.get(client.voice_clients, guild=ctx.guild)
if voice.is_paused():
voice.resume()
else:
await ctx.send("The audio is not paused.")
#client.command()
async def stop(ctx):
voice = discord.utils.get(client.voice_clients, guild=ctx.guild)
voice.stop()
client.run('Token')
I have tried converting the file to an mp3 but I am unsure how to get this to work properly. All I need is for the .webm file to be converted to a .mp3 file so that discord can read this.

Answer 1

You need to add ffmpeg to path
Open windows search bar and open up 'edit the system environment variables'
Then click on environment variables on the bottom
Click on path and edit
after that just find where you downloaded ffmpeg and add it
