receiving audio from a user and playing it with ffplay

This is my code:

let connection = joinVoiceChannel({
    adapterCreator: message.guild.voiceAdapterCreator,
    channelId: message.member.voice.channel.id,
    guildId: message.guild.id,
    selfDeaf: false,
    selfMute: true
});

let subscription = connection.receiver.subscribe(message.author.id, {
    autoDestroy: false,
    emitClose: false
});

const ffplay = exec('ffplay -');

subscription.pipe(ffplay.stdin)

let connection = joinVoiceChannel({
    adapterCreator: message.guild.voiceAdapterCreator,
    channelId: message.member.voice.channel.id,
    guildId: message.guild.id,
    selfDeaf: false,
    selfMute: true
});

let subscription = connection.receiver.subscribe(message.author.id, {
    autoDestroy: false,
    emitClose: false
});

const ffplay = exec('ffplay -');

subscription.pipe(ffplay.stdin)

It looks like the subscription is giving audio but the ffplay is not playing it.

• What's your exact discord.js npm list discord.js and node node -v version? • Post the full error stack trace, not just the top part! • Show your code! • Explain what exactly your issue is. • Not a discord.js issue? Check out #useful-servers.

sorry, its [email protected] and also @discordjs/[email protected] its all defined, no errors, ffplay is installed and its working out of the code node version is v19.7.0

Is it possible that when your bot joins the channel it mutes its self

NounejmOP•2y ago

selfDeaf is for the bot to hear, def true selfMute is for the bot to talk, def false its also getting the packets, ffplay is just not playing them I see i am getting ignored

this isn't ffplay support, but I imagine it doesn't support playing an opus packet stream you can utilize the opus.Decoder class from prism-media (which @discordjs/voice depends on) to decode the opus packet stream to pcm https://amishshah.github.io/prism-media/opus.Decoder.html

this is the updated version, it does actually pop up a ffplay window but the audio is just bunch of random noises, "whitenoice"?

you'll probably need some extra ffplay args to specify the format of what you're playing but this is leaving the scope of this channel

NounejmOP•2y ago

All fixed, thank you One more thing, can the bot recrod the whole voice room and hot just 1 user?

duck•2y ago

there is no method for receiving all users in the voice channel as 1 stream if that's what you're asking you can call <VoiceReceiver>.subscribe() as many times as you want

NounejmOP•2y ago

So i have to add a logic for when the user leaves channel, joins channel, types the command? cool
