• Discord.js Music bot "TypeError" when playing audio with dispatcher

  21 février 2020, par Cole Perry

  I’m new to Discord.js and I’m trying to have the bot join a voice channel and play an audio file on my computer. I have been following this guide : https://discord.js.org/#/docs/main/stable/topics/voice . Here is the Index.js page :

  Colesbot.on('message', message=>{
  
      if (message.content === '/join') {
  
          // Only try to join the sender's voice channel if they are in one themselves
  
          if (message.member.voiceChannel) {
  
              message.member.voiceChannel.join().then(connection => {
  
                  message.reply('I have successfully connected to the channel!');
  
  
  
                  // To play a file, we need to give an absolute path to it
  
                  const dispatcher = connection.playFile('C:\Users\bobal\Documents\GitHub\Spotify-Playlist-Discord-bot\Assets\Glory.mp3');
  
  
  
                  dispatcher.on('end', () => {
  
                      // The song has finished
  
                      console.log('Finished playing!');
  
                    });
  
  
  
                  dispatcher.on('error', e => {
  
                      // Catch any errors that may arise
  
                      console.log(e);
  
                    });
  
  
  
                    dispatcher.setVolume(0.5); // Set the volume to 50%
  
              }).catch(console.log);
  
      } else {
  
          message.reply('You need to join a voice channel first!');
  
        }
  
      }
  
   });
  
  exports.run = (client, message, args) => {
  
      let user = message.mentions.users.first || message.author;
  
  }

  FFMPEG is installed and I have set the environment path for it. When I type FFMPEG in the command line I get the proper response.

  Some have said I need to install the ffmpeg binaries but when I run npm install ffmpeg-binaries I get an error message that is here

  So then I tried installing an older version and I’m now using ffmpeg-binaries@3.2.2-3 but when I type /join I get the error

  [ERR_INVALID_ARG_TYPE]: The "file" argument must be of type string. Received type object

• How to change or modify pitch of audio file (music etc like .mp3 file)using FFMPEG ?

  18 octobre 2022, par syed kashifullah

  I want to change and modify pitch an .mp3 audio file using FFMPEG.
But I am unable to use FFMPEG to change or modify pitch of that sound.
what command (exact command) should be exactly use for changing pitch of an audio file ?

  


   String outPutPath = new File("/storage/emulated/0/Share it Application/Over_the_HorizonTemp.wav").getPath();
                 
                String[] strFfmpeg  = {"ffmpeg","-i" ,strInputPath,"-af", "rubberband=tempo=1.0:pitch=1.5:pitchq=quality" ,outPutPath};
                execffmpegBinary(strFfmpeg);


  


  execffmpegBinary Function :

  


  public void execffmpegBinary(String[] command) {
    Config.enableLogCallback(new LogCallback() {
        @Override
        public void apply(LogMessage message) {
            Log.e(Config.TAG, message.getText());
            Log.e("TAG", "apply: " +message.getText());
        }
    });
    Config.enableStatisticsCallback(new StatisticsCallback() {
        @Override
        public void apply(Statistics statistics) {

        }
    });

    long executionId = FFmpeg.executeAsync(command, new ExecuteCallback() {
        @Override
        public void apply(long executionId, int returnCode) {
            if (returnCode == RETURN_CODE_SUCCESS) {
                
                Log.e("1TAG", "apply:return code "+returnCode );
                Log.e("1TAG", "apply:execution Id "+executionId );
                Log.e("1TAG", "apply:execution Id "+ new FFmpegExecution(executionId,command));


            } else if (returnCode == RETURN_CODE_CANCEL) {
                Log.e("2TAG", "apply:return code "+returnCode );
                Log.e("2TAG", "apply:execution Id "+executionId );
                Log.e("2TAG", "apply:execution Id "+ new FFmpegExecution(executionId,command));

            } else {
                Log.e("3TAG", "apply: returnCode"+ returnCode);
                Log.e("3TAG", "apply:return code "+returnCode );
                Log.e("3TAG", "apply:execution Id "+executionId );
                Log.e("3TAG", "apply:execution Id "+ new FFmpegExecution(executionId,command));

            }
        }
    });
}


  


• Http 400 error : requesting https site with ip instead of hostname Android

  8 novembre 2016, par David Barishev

  Im am developing an android application using xamarin.android.
  In my application i use ffmpeg as a static library, from here.

  In my app i try to access a https site, but i was getting a dns error until i read the documentation, it stated that :

  A limitation of statically linking glibc is the loss of DNS
  resolution. Installing
  nscd through your package manager will fix this or you can use
  "ffmpeg -i http://<ip address="address" here="here">/"</ip> instead of "ffmpeg -i http://example.com/"

  So i tried to lookup the ip address and just replace the hostname. Here is the code i have written :

  ...
  
  //part of main program
  
  if (inputUrl.StartsWith("http"))
  
  {
  
     var splits = inputUrl.Split('/');
  
     var hostName = splits[2];
  
     var ip = GetIpForHost(hostName);
  
     splits[2] = ip;
  
     inputUrl= string.Join("/",splits);
  
  }
  
  //calling ffmpeg with the new url
  
  ...
  
  
  
  private static string GetIpForHost(string hostname)
  
  {
  
      System.Net.IPHostEntry host = System.Net.Dns.GetHostEntry(hostname);
  
      return host.AddressList.First().ToString();
  
  }

  The code works fine, but now i’m getting different error, here is the ffmpeg log :

  [https @ 0xb2b08e0] HTTP error 400 Bad Request

  The original url i tried :

  https://r8---sn-ivuoxu-ua8l.googlevideo.com/videoplayback?pl=26&itag=22&mt=1478622247&ms=au&ei=Mv0hWLWEAs-VW7zch6AB&mv=m&upn=DLluZN9oSzo&mn=sn-ivuoxu-ua8l&expire=1478644114&mm=31&ratebypass=yes&id=o-AC_NwrGbkh5OVe-ypJh2WaxzMBK5grMVsSYyG_wMQVZI&ip=5.29.246.6&pcm2cms=yes&key=yt6&lmt=1478408938763105&dur=229.575&initcwndbps=2682500&ipbits=0&gcr=il&requiressl=yes&sparams=dur,ei,gcr,id,initcwndbps,ip,ipbits,itag,lmt,mime,mm,mn,ms,mv,pcm2cms,pl,ratebypass,requiressl,source,upn,expire&mime=video/mp4&source=youtube&signature=0E47DFC7FBBDBCD6F36B56FB9871ED3B0DF4D12A.103BAB44FFEE918B78C7D076243B45AF69C444EC

  I have no problem accessing the original url through the browser, at the time i ran the program(There is a expired tag in the url,since i’m generating it at runtime).

  I speculate that it’s not possible to connect via https through ip ?
  Is there another way to connect to the url without the hostname, since android does have build in dns resolution, since i am able to view the url through the browser ?
