• FFMPEG no audio / broken audio after concat

  18 octobre 2018, par Noniq

  First, I’m converting from mp3 to mp4, using a jpg file as background :

  ffmpeg -loop 1 -i bg.jpg -i song.mp3 -c:a copy -c:v libx264 -shortest output.mp4

  Then, I’m trying to concatenate multiple mp4 files to a video :

  ffmpeg -f concat -safe 0 -i list.txt -c copy mix.mp4

  list.txt contains a list of video files :

  file 'output1.mp4'
  
  file 'output2.mp4'

  Problem : After concat, the audio stream isn’t working properly. The audio of the first video is correct, but for the second video it’s either silent (Groove Music player, Chrome) or when uploaded to YouTube, it skips like every third of a second.
  Only in VLC media player it’s working properly.

  Every file used to be an mp3 file and is converted to mp4 using the same encoding options - thus I expected it to work with demuxing - but apparently, something went wrong.

• Discord.js v14 : AudioPlayer isn't working

  6 septembre 2023, par colonelPanic

  I'm new to javascript in general, and I'm making a Discord bot that can join a voice channel and play some audio. When I run the slash command that I set up, I get no errors and a reply that suggests that everything is running correctly, but no audio is playing. I've looked at the documentation for the audio player and some examples of how to do this on youtube, but I can't find any hints as to why there's no audio.

  


  The command that I'm using to handle the audio player is shown below :

  


  // These are the contents of the 'play.js' file where I'm defining and exporting the slash command 

const { SlashCommandBuilder } = require('discord.js');
const { createAudioPlayer, 
        NoSubscriberBehavior, 
        AudioPlayerStatus,
        getVoiceConnection,
        createAudioResource,
        joinVoiceChannel
      } = require('@discordjs/voice');

module.exports = {
    data: new SlashCommandBuilder()
        .setName('play')
        .setDescription('Plays a song/sound in the voice channel you are in.')
        .addStringOption((option) => 
            option
            .setName('sound')
            .setDescription('The sound/song to play.')
            .setRequired(true)
            .addChoices(
                {name: 'spiderman-pizza', value: 'https://www.youtube.com/watch?v=czTksCF6X8Y'},
                {name: 'royaltyfree-1',   value: 'C:/resources/sounds/royaltyfree-1.mp3'}
            )
        ),
    async execute(interaction) {
        // Create the audio player
        const audioPlayer = createAudioPlayer({
            behaviors: {
                noSubscriber: NoSubscriberBehavior.Pause,
            },
        });
        // Get the existing voice connection
        var connection = getVoiceConnection(interaction.guild.id);
        // If there is no existing connection, create one
        if (!connection) {
            connection = joinVoiceChannel({
                channelId: interaction.member.voice.channel.id,
                guildId: interaction.guild.id,
                adapterCreator: interaction.guild.voiceAdapterCreator
            });
        }
        // Get the chosen audio resource and play it in the voice channel
        const resource = createAudioResource(interaction.options.getString('sound'));
        audioPlayer.play(resource);
        connection.subscribe(audioPlayer);

        interaction.reply({content: `Playing ${interaction.options.getString('sound')}`, ephemeral: true});
    }
}


  


  I don't get any errors when I execute this command with either of the available choices, but the audio player doesn't play anything. On the Discord server, I've given the bot all permissions except for Administrator, and the intents that I've specified in the code can be seen below :

  


  const { 
    Client, 
    Collection, 
    Events, 
    GatewayIntentBits,
 } = require('discord.js');

// Create a new client instance
const client = new Client({ 
    intents: [
            GatewayIntentBits.Guilds,
            GatewayIntentBits.MessageContent,
            GatewayIntentBits.GuildMessages,
            GatewayIntentBits.GuildMembers,
            GatewayIntentBits.GuildVoiceStates
            ] 
        }
    );


  


  I know that the '/play' command is registered and that the bot can join the user's voice channel when '/play' is executed. I've installed 'libsodium-wrappers' (encryption package), 'ffmpeg-static', and '@discordjs/voice' using npm so I don't think there should be any dependency issues. Does anyone have an idea of why the audio isn't playing ?

  


• pydub unable to find the selected files

  4 février 2021, par big_Z_0909

  my code is as below

  


  import pydub
from pathlib import Path
import os, sys

pydub.AudioSegment.converter = r"D\\Anaconda3\\Scripts\\ffmpeg-2021-02-02-git-2367affc2c-essentials_build\\bin\\ffmpeg.exe"
pydub.AudioSegment.ffprobe = r"D\\Anaconda3\\Scripts\\ffmpeg-2021-02-02-git-2367affc2c-essentials_build\\bin\\ffprobe.exe"

my_file = "D:\\Anaconda3\\Scripts\\outcall\\luyinwenjian\\20210203.mp3"
song = pydub.AudioSegment.from_mp3(my_file)


  


  i downloaded the essential windows eddition of ffmpeg from the official website. i still cannot load the mp3 file from the document, got the FileNotFoundError : [WinError 2]. In the warning, it said that it could find ffprobe and ffmpeg, but in fact the path is correct in the code. Does anyone point out what exactly i went wrong here ?
