• 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;
        }
    }
}

• NodeJs watch file Chokidar and create Thumbnail with FFMPEG, Code is hanging. Memory jam ?

  30 juillet 2021, par Mert

  I'm trying watch file Chokidar. Mp4 files in Folder. And I'm trying watch folder with create thumnail. But My code is hanging. It's getting stuck. I'm waiting ten min but i didnt get error and my code worked more little. Again, I'm waiting more ten min. But no change anything.

  


  Code :

  


  let fs = require('fs');
var chokidar = require('chokidar');
const ffmpegInstaller = require('@ffmpeg-installer/ffmpeg');
const ffmpeg = require('fluent-ffmpeg');
ffmpeg.setFfmpegPath(ffmpegInstaller.path)

var counter = 0

var Mywatcher = chokidar.watch('Z:\\WatchFolder', {ignored: /^\./, persistent: true, usePolling: true});
Mywatcher
  .on('add', function(path) {
    worder = '.mp4'
    if(path.includes(worder)){
 
            counter = counter + 1 
            
            console.log('added' + counter)

            ffmpeg({ source: path })
            .on('filenames', (filenames) => {
                console.log('Created file names', filenames);
            })
            .on('end', () => {
                console.log('Job done');
            })
            .on('error', (err) => {
                console.log('Error', err);
            })
            .takeScreenshots({
                filename: counter +'.jpg',
                timemarks: [ 2 ],
             
            }, 'public/images/thumbnail/');
      
    }

    })

  .on('change', function(path) {console.log('File', path, 'has been changed');})



  .on('unlink', function(path) {

  })




  .on('error', function(error) {console.error('Error happened', error);})
