• Discord Bot can't play audio from YouTube all of a sudden

  22 mars 2023, par Aidan Tweedy

  Last night my Discord bot stopped working out of the blue. The bot had been working perfectly for months until this point - no code changes occurred and it was running in a Docker container on my home server. Then last night, my !play <url></url> command stopped working. The bot would join the voice channel, but not actually play anything. Then it would need to be manually disconnected from the voice channel in order for it to do anything again. After the first play fails, and I try again I get this error message :

 [2023-03-22 00:27:59] [INFO    ] discord.player: ffmpeg process 12 should have terminated with a return code of -9.


  


  My first instinct was that ffmpeg was borking somehow, since it has been difficult to get working in the past. However I'm not sure how ffmpeg could've stopped working, since the bot never went down between working and not working. That leads me to believe it could be a change on Youtube/Discord's side ?

  


  For context, here is a snippet of my !play code :

  


  @client.command(pass_context = True)
async def play(ctx):
    url = ctx.message.content.split("!play ",1)[1]
    voice = discord.utils.get(client.voice_clients)
    if (ctx.author.voice):
        if voice == None:
            channel = ctx.message.author.voice.channel
            voice = await channel.connect()

        # Youtube Magic
        ydl_opts = {
        'format': 'worstaudio/worst',
        'postprocessors': [{
            'key': 'FFmpegExtractAudio',
            'preferredcodec': 'mp3',
            'preferredquality': '192',
        }],
        }

        if "http" not in url:
            yt = YoutubeSearch(url, max_results=1).to_json()
            print(yt)
            yt_id = str(json.loads(yt)['videos'][0]['id'])
            yt_channel = str(json.loads(yt)['videos'][0]['channel']).strip().replace(" ", "")
            url = 'https://www.youtube.com/watch?v='+yt_id+"&ab_channel="+yt_channel

        with yt_dlp.YoutubeDL(ydl_opts) as ydl:
            song_info=ydl.extract_info(url, download=False)
        for file in os.listdir("./"):
            if file.endswith(".mp3"):
                os.rename(file, "song.mp3")

        voice.stop()

        embed_trk = discord.Embed(
                title="Now playing",
                color=ctx.author.color,
        )
        video_title = song_info.get('title', None)
        video_channel = song_info.get('uploader', None)
        embed_trk.add_field(name="Track title", value=video_title, inline=False)
        embed_trk.add_field(name="Channel", value=video_channel, inline=False)

        await ctx.send(embed=embed_trk)
        player = await YTDLSource.from_url(url, loop=client.loop, stream=True)
        voice.play(player, after=lambda e: print(f'Player error: {e}') if e else None)
        while voice.is_playing():

• Discord Voice Bot cannot play the audio file

  7 avril 2023, par Jakub Nawrocki

  I tried to write a bot that will join the voice channel and play a audio at 20:00.

  &#xA;

  Currently the bot joins the channel, but immediately after that it disconnects without making a single sound with this message :

  &#xA;

  Any ideas ?

  ffmpeg has been installed properly.
