• FFmpeg doesn't play any audio through Discord.py BOT

  12 mai 2019, par Lewis H

  Here is my code for my Discord bot’s play function :

  @bot.command()
  
  async def play(ctx, url:str = None): # DOESN'T WORK, DOWNLOADS BUT DOESN'T PLAY
  
  
  
          ...
  
  
  
          ytdl_options = {
  
              'format': 'bestaudio/best',
  
              'postprocessors': [{
  
                  'key': 'FFmpegExtractAudio',
  
                  'preferredcodec': 'mp3',
  
                  'preferredquality': '192',
  
              }],
  
          }
  
          ytdl = youtube_dl.YoutubeDL(ytdl_options)
  
  
  
          loop = asyncio.get_event_loop()
  
          data = await loop.run_in_executor(None, lambda: ytdl.extract_info(url))
  
  
  
  
  
          if 'entries' in data:
  
              data = data['entries'][0] # taking top item from a YT playlist
  
  
  
          source = ytdl.prepare_filename(data)
  
  
  
          vc.play(discord.FFmpegPCMAudio(source)) #play audio
  
          print(vc.is_playing())
  
          await ctx.send("Now playing: " + data.get('title')) #now playing
  
          asyncio.sleep(3)
  
          print(vc.is_playing())

  When I call the function, it runs fine and downloads the video from youtube-dl, then sends the message "Now playing : X", but doesn’t play any audio.

  I added the two print(vc.is_playing()) lines and what is returned in the shell is :

  True
  
  False

  So clearly it tries to play the song but immediately fails.

  There are no exceptions thrown, so I can’t understand why FFmpeg doesn’t want to play the audio.

• Discord JS dispatcher goes immediately on finish

  2 juillet 2021, par JonJon

  I experienced some issues with my Discord bot. I want to play a mp3-file in a voice channel. But the dispatcher goes immediately on status 'finish' and the song doesn't play. There are no errors. First I thought that ffmpeg might be the problem. But ffmpeg seems to work fine. Then I tried reinstalling nodejs. This didn't work out as well. The code can't be the problem as well, because it worked fine last week.
Has anyone an idea ?
Code :

  


  


  


  const Discord = require('discord.js');
const client = new Discord.Client();

client.login('token');

client.on('message', async msg =>{
    if(msg.content === 'play'){
        msg.reply('playing');
        const connection =  await msg.member.voice.channel.join();

        const player = connection.play('musik.mp3');

        player.on('finish', () => {
            msg.member.voice.channel.leave();
        });
    }
});

  


  


  



• FFmpeg - how to set output sample_size

  23 décembre 2019, par DennisJ

  Trying to create a simple command line player for .dsf (DSD audio) files, and output to an alsa device that supports up to 24-bit 192 kHz sample rate. The following command almost works and it does play the track. Examining the bold text below, the dsf input file is converted to 24-bit/192 kHz, but the output is then truncated to 16-bit 192 kHz (pcm_s16le i.e, 16 bit little endian).

  ffmpeg -i ’01 - Sweet Georgia Brown.dsf’ -f alsa hw:0,0

  After displaying the ffmpeg banner and song metadata (tags), here is the result, bold is my emphasis :

  Duration : 00:05:14.83, start : 0.000000, bitrate : 9234 kb/s
  Stream #0:0 : Audio : flac, 192000 Hz, stereo, s32 (24 bit)
  Stream mapping :
  Stream #0:0 -> #0:0 (flac (native) -> pcm_s16le (native))
  Press [q] to stop, [?] for help
  Output #0, alsa, to ’hw:0,0’ :

  Since I can play this and many other tracks at full resolution using another player (foobar2000) it seems there might be an option in the encoder which is part of FFmpeg : Lavf57.83.100 I can find no information in any of the FFmpeg documentation that helps. Tried finding options in FFplay and even guessing using other FFmpeg options like this example.
  ffmpeg -sample_fmt s24 -i ’01 - Sweet Georgia Brown.dsf’ -f alsa hw:0,0 ***** same results.

  I’m stuck. Any suggestions ?

  Environment : Linux Mint 19.2, 64-bit, ASUS Xonar STXii sound card.
