• I tried programming a discord bot for music, it joins the channel, it apparently "speaks" but i can't hear anything

  2 avril 2020, par borax

  I tried to code it alone, but I got the same problem, then I copied the code from https://gabrieltanner.org/blog/dicord-music-bot and it persists. I have downloaded FFmpeg, but I still think the problem lies there. Any suggestions ? (it's my first time here, I don't know how much of the code is relevant, also, i get this Error : FFmpeg/avconv not found !)

• issue with ffmpeg (not loading song ?) - ffmpeg stream : write EPIPE

  15 novembre 2020, par super

  issue : with some songs that i play through the StreamDispatcher from the discord.js module (seems to be ones that have silences at the beginning), the dispatcher will almost immediately finish and throw an error. i use the ffmpeg-static module.

  


  from what i've seen, these are the two errors that i'm receiving from calling the "debug" and "error" events of the dispatcher

  


  Error: ffmpeg stream: write EPIPE

  


  Error [ERR_STREAM_DESTROYED]: ffmpeg stream: Cannot call write after a stream was destroyed

  


  reproducible code sample (requires ytdl-core) :

  


  /**
* @param {Discord.VoiceConnection} connection 
* @param {String} url 
*/
async function run(connection, url) // assuming these two variables aren't null
{
    const video = ytdl(url, { highWaterMark: 5242880 });
    video.on("error", (err) => console.log(err));
    let dispatcher = connection.play(video);
    dispatcher.on("finish", () => console.log("finished"));
    break;
}
// recommended url: https://www.youtube.com/watch?v=Auk1oVI2Icw
// (this is one i've been using to test this issue)


  


  original code from my project plus some comments from guiding :

  


  async play() // this is my function for playing music on the bot
{
    if (this.queue.length === 0) return;
    if (!this.guild.me.voice || !this.guild.me.voice.channel) return;
    let connection = this.guild.me.voice.connection;
    if (!connection) return;
    if (connection.dispatcher) return;
    let track = this.queue[0];
    let channel = this.guild.channels.cache.get(track.channelID);
    switch (track.type)
    {
        //case "soundcloud" omitted
        case "youtube":
        {
            const video = ytdl(track.url, { highWaterMark: 5242880 });
            video.on("error", (err) => console.log(err));
            channel.send(`playing: **${track.name}** // requester: **${track.requester.tag}**`);
            let dispatcher = connection.play(video); // dispatcher will begin
            dispatcher.setVolume(this.volume);
            dispatcher.on("finish", () => this.finish()); // almost immediately the following will be called
            // fyi: there isn't anything special in the function called, just some code to shift the queue
            break;
        }
    }
}

• checkasm : Explicitly declare function prototypes

  20 août 2015, par Henrik Gramner

  checkasm : Explicitly declare function prototypes
  Now we no longer have to rely on function pointers intentionally
  
  declared without specified argument types.
  This makes it easier to support functions with floating point parameters
  
  or return values as well as functions returning 64-bit values on 32-bit
  
  architectures. It also avoids having to explicitly cast strides to
  
  ptrdiff_t for example.
