Ffmpeg was not found. How do i fix this?

So im trying to make a simple discord music bot, which is halted right now due to this problem. The issue is that everytime i try to play a music through youtube_dl library, it pops up with the prompt: "ffmpeg was not found".

This is the main.py

import discordimport osimport asyncioimport youtube_dlimport ffmpegtoken = 'NzY5NTUzNDcwNjAwMTE4Mjgz.G3Dzce.XYKNAyLfBPg0ug5XPKssV-9EvsFjBlCMeM43ag'client = discord.Client()block_words = ['dick', 'nigga', 'ujku shijakut', 'arli', 'http://', 'https://']voice_clients = {}yt_dl_opts = {'format': 'bestaudio/best'}ytdl = youtube_dl.YoutubeDL(yt_dl_opts)ffmpeg_options = {'options': '-vn'}@client.eventasync def on_ready():print(f'Bot has logged in as {client.user}')@client.eventasync def on_message(msg):if msg.author != client.user:if msg.content.lower().startswith('?hi'):await msg.channel.send(f'Hi, {msg.author.display_name}')@client.eventasync def on_message(msg):if msg.author != client.user:for text in block_words:if "OTR" not in str(msg.author.roles) and text in str(msg.content.lower()):await msg.delete()returnprint("Not Deleting...")@client.eventasync def on_message(msg):if msg.content.startswith('?play'):try:url = msg.content.split()[1]voice_client = await msg.author.voice.channel.connect()voice_clients[voice_client.guild.id] = voice_clientloop = asyncio.get_event_loop()data = await loop.run_in_executor(None, lambda: ytdl.extract_info(url, download=False))song = data['url']player = discord.FFmpegPCMAudio(song, **ffmpeg_options)except Exception as err:print(err)client.run(token)
