• How can I merge discord voice streams ?

  3 mars 2023, par LeGlaude

  I'd like to merge the voice of users that I receive using the discordjs/voice library. The number of streams to merge has to be flexible. Also, The output stream has to be readable so I can use it as a source.

  


  I tried different libraries like fluent-ffmpeg, ffmpeg and merge-stream. My discord bot didn't crash when I was using fluent-ffmpeg to merge n streams but no sound was streamed. Sadly, I don't have my previous code when I used fluent-ffmpeg. I have my code that uses merge-stream. The problem with merge-stream is that when I try to merge streams it says "TypeError : source.once is not a function". Here is my code :

  


  async function CreateStream(server_id) {
    let users = client.channels.cache.get(GetVoiceChannel(server_id)).members.map(user => user.id)
    if (users.indexOf(bot_id) != -1) {
        users.splice(users.indexOf(bot_id), bot_id)
    };

    console.log(users)

    const connection1 = getVoiceConnection(server_id)
    const connection2 = getVoiceConnection(GetCall(server_id))

    const streams = []

    for (const user in users) {
        const sub = connection1.receiver.subscribe(user, { end: EndBehaviorType.Manual })
        streams.push(sub)
    }

    const theStream = merge()

    for (const stream in streams) {
        theStream.add(stream)
    }

    const resource = createAudioResource(theStream, {inputType: StreamType.Opus})
    const player = createAudioPlayer()

    connection2.subscribe(player);
    player.play(resource);
    
}


  


  EDIT :

  


  Now this is my code :

  


  
async function CreateStream(server_id) {
    let users = client.channels.cache.get(GetVoiceChannel(server_id)).members.map(user => user.id)
    if (users.indexOf(bot_id) != -1) {
        users.splice(users.indexOf(bot_id), bot_id)
    };

    const connection1 = getVoiceConnection(server_id)
    const connection2 = getVoiceConnection(GetCall(server_id))

    let merge_param = []

    for (const user in users) {
        const sub = connection1.receiver.subscribe(user, { end: EndBehaviorType.Manual })
        merge_param.push('-i')
        merge_param.push(sub)
    }

    merge_param.push('-','-sample_fmt', 's16', '-ar', '48000','-ac', 2, '-acodec', 'libopus','-b:a', '192k', '-vbr', 'on', '-compression_level', '10', '-f', 'opus', 'pipe:1')

    const ffmpeg = cp.spawn('ffmpeg', merge_param);

    const resource = createAudioResource(ffmpeg.stdout, {inputType: StreamType.Opus})
    const player = createAudioPlayer()

    connection2.subscribe(player);
    player.play(resource);
    
}



  


  I don't have an error anymore but no sound is coming out from the bot.

  


• 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.

  


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

    try:
        source = discord.FFmpegPCMAudio('audio.mp3')
        print(f"Audio file loaded: {source}")
        voice_client.play(source)
        while voice_client.is_playing():
            await asyncio.sleep(1)
    except Exception as e:
        print(f"Audio could not be played: {e}")

@client.event
async def on_ready():
    print('Bot is ready')
    now = datetime.datetime.now()
    target_time = datetime.time(hour=20, minute=00)
    if now.time() >= target_time:
        print(f"Current time: {now.time()}. Bot did not join channel.")
        return
    else:
        print(f"Current time: {now.time()}. Bot has joined at {target_time}.")
        await asyncio.sleep((datetime.datetime.combine(datetime.date.today(), target_time) - now).total_seconds())
        channel = client.get_channel(CHANNEL_ID)
        if channel is not None:
            try:
                voice_client = await channel.connect()
                print(f'{client.user} joined voice chat.')
                await asyncio.sleep(1)
                await play_sound(voice_client)
                await voice_client.disconnect()
                print(f'{client.user} left voice chat.')
            except Exception as e:

                print(f"Error during joining channel : {e}")
        else:
            print(f"Did not find a channel of ID {CHANNEL_ID}.")

client.run(TOKEN)


  


  Any ideas ?

  


  ffmpeg has been installed properly.

  


• discordjs/voice : Changing volume does not have any effect

  27 avril 2023, par Coxcopi

  I'm using @discordjs/voice for a bot. When I try to change the audio volume of a resource, no matter if it's while the resource is being played currently or if I do it before playing it, it doesn't seem to have any effect.

  


  My code for creating the resource looks like this :

  


  const stream = ytdl(url, {
    filter: "audioonly",
    format: "mp3",
    highWaterMark: 1 << 62,
    liveBuffer: 1 << 62,
    dlChunkSize: 0,
    bitrate: 128,
    quality: "lowestaudio"
})
const resource = createAudioResource(stream, {inlineVolume: true});


  


  And for changing the volume before playing :

  


  resource.volume.setVolume(audioVolume);
audioPlayer.play(resource);


  


  I've tried audioVolume values between 0.0-1.0 as well as between 0-100 but no matter the value, the audio volume stayed exactly the same. Any Ideas what could be the issue here ?
