• discord.py and ffmpeg : Play a sound effect while playing music

  26 juin 2022, par JPhusion

  I would like to play a sound effect while playing music in a vc using discord.py and ffmpeg. I know you cannot play more than one audio source at a time, so instead I am trying to pause the music, play the sound effect and continue the music.

  


  This is what I've come up with so far, but because I am playing the sound effect, the resume() method no longer works after the pause().

  


  @commands.command()
    async def sfx(self, ctx):
        try:
            voice = await ctx.author.voice.channel.connect()
        except:
            voice = ctx.guild.voice_client
        try:
            voice.pause()
            # voice.play(discord.FFmpegPCMAudio('./media/sfx/notification.mp3'))
        except:
            voice.pause()
            # voice.play(discord.FFmpegPCMAudio(executable=r"C:\Users\josh\Programming\Discord\ffmpeg\bin\ffmpeg.exe", source='./media/sfx/notification.mp3'))
        guild = self.client.get_guild(752756902525403156)
        member = guild.get_member(876292773639233596)
        print(member.activities[0].name)
        await asyncio.sleep(1)
        voice.resume()
        if member.activities[0].name == "Not playing music":
            await voice.disconnect()


  


• FFMPEG record sound stop always at the same size

  12 mai 2022, par gildas

  I try to record live sounds catch by a device (raspberry Pi with microphones) in my computer (linux).
I use this command on the device :

  


  arecord -D dmic_sv -c2 -r 48000 -f S32_LE -t wav | \
ffmpeg -re -f wav -i pipe: \
       -f s16le -acodec pcm_s16le -ac 1 -ar 48000 -af "volume=16dB" 
       tcp://ipPC:55000


  


  I use this command on my PC :

  


  FFREPORT=file=ffreport.log:level=32 \
ffmpeg -f s16le -acodec pcm_s16le -ac 1 -ar 48000 \
       -i tcp://ipPC:55000?listen -f wav fichiercible.wav


  


  It is working but the record always stops when fichiercible.wav reach 536.9Mo.

  


  I tried to put this option -fs 2000000000 on the command on my PC :

  


  FFREPORT=file=ffreport.log:level=32 \
  ffmpeg -f s16le -acodec pcm_s16le -ac 1 -ar 48000 \
         -i tcp://ipPC:55000?listen \
         -f wav -fs 2000000000 fichiercible.wav


  


  But the result was the same, the record stop when the file is 536.9Mo

  


  Is it possible to record bigger size file with ffmpeg ?

  


• Java Playing Sound From YouTube

  8 mai 2022, par etkmlm

  I'm in a LWJGL game and want to play sound from YouTube. I have the stream link but can't play it anymore.

  


  public void playMusic(Music m) throws IOException {
    String uri = m.getUrl();
    URL url = new URL(uri);
    try{
        Process p = new ProcessBuilder().command("ffmpeg.exe", "-i", uri, "-acodec", "pcm_u8", "-ar", "22050", "-f", "wav", "pipe:1").redirectError(ProcessBuilder.Redirect.INHERIT).start();

        AudioInputStream str = AudioSystem.getAudioInputStream(p.getInputStream());
        Clip clip = AudioSystem.getClip();
        clip.open(str);
        clip.start();

    }
    catch (Exception e){
        e.printStackTrace();
    }

}


  


  It throws "Chunk size too big" error. I started ffmpeg alone but in this time, ffmpeg throws "invalid argumentsize=" error.
