title: FFmpeg not working (discord.py)
body: <p>Code:</p>
  
  <pre><code>channel = ctx.message.author.voice.voice_channel
  link = "https://youtube.com/watch?v=videoidhere"
  voice = await bot.join_voice_channel(channel)
  player = voice.create_ytdl_player(link)
  player.start()
  </code></pre>
  
  <p>I'm getting this error:</p>
  
  <pre><code>AttributeError: 'generator' object has no attribute 'start'
  </code></pre>
  
  <p>Might FFmpeg be broken? If yes, I can't find a way to uninstall FFmpeg deleting the installation folder.</p>
