• Discord.js voice stop playing audio after 10 consecutive files

  29 avril 2021, par Spiralio

  I am trying to do the simple task of playing a single MP3 file when a command is run. The file is stored locally, and I have FFmpeg installed on my computer. The code below is part of my command's file :

  


  const Discord = require("discord.js");
const fs = require('fs');
const { Client, RichEmbed } = require('discord.js');
const config = require("../config.json");

let playing = undefined;
let connection = undefined;

module.exports.run = async (client, message, args, config) => {


  if (playing) playing.end()
  if (connection == undefined) await message.member.voice.channel.join().then((c) => {
    connection = c;
  })
  playing = connection.play('./sounds/sound.mp3')

}


  


  (note that this code is heavily narrowed down to single out the issue)

  


  When I run the command the first 9 times, it works perfectly - the file is played, and cuts off if it is already playing. I also want to note that the file is 2 minutes long. However, once I play the file for exactly the 10th time, the bot stops playing audio entirely - as long as all 10 times are overlapping (meaning I don't let the audio finish).

  


  What's more confusing is that if an error is passed after the bot stops playing audio, it appears in an entirely different format than the standard Discord.js errors. For example, this code does not test to see if the user is in a voice channel, so if I purposefully crash the bot by initiating the command without being in a voice channel (after running the command 10 times), the error looks like this :

  


  abort(RangeError: offset is out of bounds). Build with -s ASSERTIONS=1 for more info.
(Use `electron --trace-uncaught ...` to show where the exception was thrown)


  


  (Preceded by a bunch of unformatted code) This however, is not consistent. It seems to only appear after letting the files run entirely.

  


  The issue only fixes itself when the entire bot restarts. Any help would be appreciated.

  


• Create background sound for video with ffmpeg

  23 novembre 2020, par Neret

  I have a video file without sound and a stereo audio file. Video is several times longer than audio. I'd like to create a background sound which starts from 2 second silence, then trim silence of the audio at both ends and duplicate trimmed audio several times to the end of the video.

  


  

  


  I found how to trim audio :

  


  ffmpeg -y -i audio.wav -af silenceremove=start_periods=1:start_threshold=-75dB,areverse,silenceremove=start_periods=1:start_threshold=-75dB,areverse trimmed_audio.wav


  


  And how to create silence :

  


  ffmpeg -y -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=48000:duration=2 silence.wav


  


  How can I duplicate the audio and combine it with the video ?

  


• writing simple linux bash program to trim video using ffmpeg [closed]

  12 août 2020, par feri ariyatmoko
  


  1. I know I can trim video using ffmpeg without re-encoding it using this following command :ffmpeg -i 'inputvideo.mp4' -vcodec copy -acodec copy -ss 00:09:33 -to 00:11:53 'output.mp4'

     


  


  2. I've tried that command, it worked like a charm.

     


  


  3. Since I will trim a lot of videos, I think it's better if I have a simple bash program to do it.

     


  


  


  This is what the program should do :

  


  

  1. I use ubuntu, so the program should be written for linux system

  


  2. I execute the program : ./videotrimmer.sh inputvideo.mp4 outputvideo.mp4

  


  3. The program asks the starting time and the time it ends.

  


  4. I enter the times.

  


  5. And done !

  


  


  Example :

  


  

  1. I want to trim the first 3 secs of a 10 secs video named videofile10secs.mp4. The file name of the trimmed video is videofile3secs.mp4

  


  2. ./videotrimmer.sh videofile10secs.mp4 videofile3secs.mp4

  


  3. The program asks the times. I input "00:00:00" and "00:00:03"

  


  4. I press the return key.

  


  5. Done. I should have a new file videofile3secs.mp4.

  


  


  How to write that ? Any help will be highly appreciated.
