• C# - Discord.Net - Trying to read audio from soundcloud and transmit it to discord

  28 mars 2022, par Bruno Braga

  I am currently working on a discord bot that is able to play a song using soundcloud.
Unfortunately, I can't seem to figure out how to get it to read from the url and stream it !
The bot it made in C#, and uses Discord.net library and ffmpeg for the audio.
Would love to hear some suggestions !

  


  These are the three functions involved :

  


  [Command("teste", RunMode = RunMode.Async)]
public async Task Play(IVoiceChannel channel = null)
{
    var audioClient = await JoinChannel(channel);
    var url = "https://soundcloud.com/campatechlive/campatech-live-feat- 
        matheus-moussa-arabian-system-vol-2-psy-trance-150-original-mix";

    var ffmpeg = new Ffmpeg(audioClient);
    await ffmpeg.SendAsync(url);
}

public async Task SendAsync(string path)
{
    using (var ffmpeg = CreateStream(path))
    using (var output = ffmpeg.StandardOutput.BaseStream)
    using (var discord = _client.CreatePCMStream(AudioApplication.Mixed))
    {
        try { await output.CopyToAsync(discord); }
        finally { await discord.FlushAsync(); }
    }
}

private Process? CreateStream(string path)
{
    return Process.Start(new ProcessStartInfo
    {
        FileName = "ffmpeg",
        Arguments = $"-hide_banner -loglevel panic -i \"{path}\" -ac 2 -f 
        s16le -ar 48000 pipe:1",
        UseShellExecute = false,
        RedirectStandardOutput = true,
    });
}


  


  I'm guessing it's something on the ffmpeg arguments, but can't kind of figure out what.

  


  I've tried a bunch of different arguments on ffmpeg, but none of them worked.
Anyone can lend me a hand ?

  


• Stream Audio to Discord (FFMPEG and Discord.Net 1.0.1)

  16 août 2017, par ComedicChimera

  I have a music bot for Discord and I want to be able to stream audio from a site directly into Discord. Currently I have to download the file and then play it which works, but also takes a lot of time. Here is part of the code for the play command (The part the plays the audio.) :

  IVoiceChannel channel = (Context.User as IVoiceState).VoiceChannel;
  
                  Music.client = await channel.ConnectAsync();
  
  
  
                  var output = CreateStream("tmpvid.mp3").StandardOutput.BaseStream;
  
                  var stream = Music.client.CreatePCMStream(AudioApplication.Music);
  
                  await output.CopyToAsync(stream);
  
                  await stream.FlushAsync().ConfigureAwait(false);

  Here is the code for the FFMPEG.

  private Process CreateStream(string path)
  
      {
  
          return Process.Start(new ProcessStartInfo
  
          {
  
              FileName = "ffmpeg.exe",
  
              Arguments = $"-hide_banner -loglevel panic -i \"{path}\" -ac 2 -f s16le -ar 48000 pipe:1",
  
              UseShellExecute = false,
  
              RedirectStandardOutput = true
  
          });
  
      }

  My code also is able to get the url and a network stream so would it be possible for me to simply pipe that stream through FFMPEG to discord or pass the url in as a parameter ? Thanks so much !
