• Discord Bot Not Playing Audio discord.js v13

  17 avril 2023, par ChronoAero

  I'm trying to make a discord bot that can play mp3 files in a voice channel.. but it doesn't seem to work as intended

  


  
            connection = joinVoiceChannel({
                channelId: voice.channelId,
                guildId: interaction.guildId,
                adapterCreator: voice.channel.guild.voiceAdapterCreator,
            });
            
            
            let resource = createAudioResource(createReadStream(join(__dirname, 'resources/try.mp3')), {
                inlineVolume : true
            });

            resource.volume.setVolume(0.2);

            console.log(join(__dirname, 'resources/try.mp3'));
            
            const player = createAudioPlayer();

            connection.subscribe(player);
            player.play(resource)
            console.log("done");

            await interaction.reply('I have joined the voice channel!');


  


  It successfully joined the voice channel, but it does not play any sound at all

  


  The bot joined the voice channel

  


  I have made sure that the directory name is correct by console.logging join(__dirname, 'resources/try.mp3')

  


  I have also tried to check the required dependency for playing audios in discord.js v13

  


  const { generateDependencyReport } = require('@discordjs/voice');

console.log(generateDependencyReport());


  


  here's the output :

  


  --------------------------------------------------
Core Dependencies
- @discordjs/voice: 0.6.0
- prism-media: 1.3.2

Opus Libraries
- @discordjs/opus: 0.5.3
- opusscript: not found

Encryption Libraries
- sodium: not found
- libsodium-wrappers: 0.7.9
- tweetnacl: not found

FFmpeg
- version: 4.4-essentials_build-www.gyan.dev
- libopus: yes
--------------------------------------------------


  


  I think the discord.js v13 docs said that it only requires any one of each Core , Opus, Encryption, and FFmpeg Dependencies (Correct me if I'm wrong)

  


  Did I miss anything ?

  


  Thank you in advance

  


• Streaming raw sound with FFMPEG

  30 juin 2020, par Dr_Click

  I'm using the ffmpeg library to decode / encode audio in JAVA, using the Process objets. The aim is to got the raw datas decoded by ffmpeg in my JAVA code and then, to send them back to ffmpeg to generate a stream or create a file.

  



  As JAVA sounds only allow wav audio datas, I made a first try with this command line :

  



  ffmpeg -i http://199.180.75.118:80 -acodec pcm_s16le -ar 44100 -ac 2 "/home/dr_click/montest.wav"


  



  It works. But, my goal is to get the frames on the fly and not a file. I thought about using a pipe but it seems it will work only with Linux and not with Windows (and no idea for MacOS)
So, I'd prefer to stream locally a wav file and to catch it with JAVA into a AudioInputStream.

  



  I wrote this command :

  



  ffmpeg -re -i http://199.180.75.118:80 -acodec pcm_s16le -ar 44100 -ac 2 -f rtp rtp://127.0.0.1:1234


  



  It semms to work on the server side. But, when I enter the below command line on the server side :

  



  ffplay rtp://127.0.0.1:1234


  



  It doesn't work at all. I got this error :

  



  

  • [rtp @ 0x7f29c8000b80] Unable to receive RTP payload type 97 without an SDP file describing it

  


  



  If I try the couple :

  



  ffmpeg -i http://199.180.75.118:80 -acodec pcm_s16le -ar 44100 -ac 2 -f rtp -sdp_file /home/dr_click/audio.sdp rtp://127.0.1.1:1234


  



  and

  



  ffplay /home/dr_click/audio.sdp


  



  I got the following error :

  



  

  • [rtp @ 0x7f7d00008040] Protocol 'rtp' not on whitelist 'file,crypto' ! if

  


  



  And if I finally try :

  



  fmpeg -protocol_whitelist file,http,rtp,tcp -i http://199.180.75.118:80 -acodec pcm_s16le -ar 44100 -ac 2 -f rtp -sdp_file /home/dr_click/audio.sdp rtp://127.0.1.1:1234


  



  I still get the same error.

  



  Which point do I miss to stream locally some raw datas and catch them back in the AudioInputStream ?

  



  Thank you for all your replies.

  


• Concatenate mp4 files in Android using halfninja ffmpeg

  21 février 2015, par Budius

  I’ve manage to compile halfninja ffmpeg scripts for Android NDK using NDK version r5c. (Unfortunately any attempt to compile with earlier NDK generated some error), also I’m not very knowledgeable on the whole NDK process, so it’s a bit hit-n-miss for me.

  His scripts are compiling ffmpeg version N-30996-gf925b24 (the specific commit he did the scripts for)

  Moving forward to my actual app.
  I manage to trim videos without problems, now I need to join/concatenate them but any attemp at using any and several combinations of the commands found on those 3 links (link1, link2, link3) generate errors such as cat is not valid, > is undefinined, unknown option filter_complex or trying to override some of the input files.

  Does anyone know if it’s possible and (how to do it), to join/concatenate mp4 videos (all same codec, size, quality, etc) using half-ninja compile of ffmpeg on Android, or how to compile/get a ffmpeg for Android using latest source codes ?

  I’ve also gave a quick try on the mp4Parser without much success.

  ultimately I was trying to get this pseudo-method to work :

  public static File concatenate(String[] inputPaths, String outputPath){
  
  
  
      // ... do stuff do generate ffmpeg commands....
  
      VideoKit v = new VideoKit();
  
      v.run(cmds);
  
  
  
      File f = new File(outputPath);
  
      return f;
  
  }
