• Unknown issue with Discord.js and ytdl, completely skips playing audio

  21 novembre 2017, par Gman0064

  One of the commands I have for my Discord bot is to play a predefined music clip in the current user’s voice channel. The bot can connect, but rather than playing the song, it instantaneously leaves. I’ve tried using both connection.playStream as well as connection.playFile, and both seem to return the same (lack of) output. Am I missing some sort of dependency or is my code just written incorrectly ? Any help would be greatly appreciated !

  const Discord = require('discord.js');
  
  const ytdl = require('ytdl-core');
  
  const client = new Discord.Client();
  
  const streamOptions = { seek: 0, volume: 1};
  
  
  
  client.on('ready', () => {
  
    console.log('Login Success');
  
  });
  
  
  
  client.on('message', message => {
  
    if (message.content === '$vaporwave') {
  
      if (!message.guild) return;
  
      if(message.member.voiceChannel) {
  
        message.member.voiceChannel.join().then(connection => {
  
          console.log("joined channel");
  
          //const stream = ytdl('https://www.youtube.com/watch?v=cU8HrO7XuiE', { filter : 'audioonly' });
  
          const dispatcher = connection.playFile('./mcp420.mp3');
  
          //const dispatcher = connection.playStream(stream, streamOptions);
  
          dispatcher.on("end", end => {
  
            console.log("left channel");
  
            message.member.voiceChannel.leave();
  
          });
  
        }).catch(err => console.log(err));
  
      }
  
    }
  
  });

• Incorporating ffmpeg in a bash script

  22 novembre 2017, par Voprosnik

  I have a very large audio mp4 file that contains several songs.

  I have generated a script which reads a text file with the times and the song names and successfully assigns starttime, endtime and songtitle in 3 variables. The script successfully echoes the variables and returns the following format :

  00:00:00 00:10:15 Song1
  
  00:10:15 00:14:20 Song2

  and so on...

  Now I am intending to use this script with ffmpeg and crop each part of the big file into smaller audio files.

  The script thus, after feeding the variables in a while loop, it reaches to the command

  ffmpeg -ss $START -t $END -i ${1} -acodec copy $SONGNAME.mp4

  Once I run the script, the first two songs are cropped, but then the whole process stops with

  Press [q] to stop, [?] for help
  
  error parsing debug value
  
  debug=0

  I checked the generated files and they play ok, but there is no way for me to know why the script stopped there and did no proceed to the rest of the file (considering that when in the script I replace ffmpeg with echo, the script echoes the variables flawlessly).

  In other words I don’t know if there is a problem in my script, ffmpeg, or the source music file.

• Mix more then 1000 mp3's sounds bad / Can I use FFmpeg to merge 1000 mp3s ?

  7 avril 2022, par maesbn

  I am working on a project where everybody has to activate a part of a song. I have about 7000 mp3's, each with the same length of the final mix but with only a small part of audio. So for example you can hear a drum hit at the 15th second and the rest of the mp3 (about 4 min.) is silence.

  



  I use the mix filter to add all the mp3's. I add them 32 mp3s at a time. 
The first test I've run results in the first mixed mp3s to be silenced ? (I set the Volume on the mix to the number of tracks) Also the sound is of poor quality after the mix. Can I fix this ?

  



  Or do you think this can not be done by ffmpeg ? Do you know an alternative program to do this ?

  



  Thanks !
