• A Soundboard for Discord with Discord.py with already downloaded .mp3 files

  8 août 2019, par Kerberos Kev

  I’m setting up a discord bot with discord.py, and want to implement an soundboard.The soundboard should take already downloaded .mp3 files and play them in the discord. The bot already automatically joins and disconnects from a voice channel but does not play any of my sound files.

  I tried converting the mp3 file into an opus one and just play it without ffmpeg but this didn’t work either.

  import discord
  
  from discord.ext import commands
  
  from discord.utils import get
  
  from mutagen.mp3 import MP3
  
  import time
  
  import os
  
  
  
  client = commands.Bot(command_prefix='<')
  
  a = './'+'kurz-kacken.mp3'
  
  
  
  
  
  class Soundboard(commands.Cog):
  
  
  
      def __init__(self, client):
  
          self.client = self
  
  
  
      @commands.command(pass_context=True)
  
      async def soundboard(self, ctx, songname: str):
  
          channel = ctx.message.author.voice.channel
  
          voice = get(client.voice_clients, guild=ctx.guild)
  
  
  
          if voice and voice.is_connected():
  
              await voice.move_to(channel)
  
          else:
  
              voice = await channel.connect()
  
  
  
              print(f"The bot has connected to {channel}\n")
  
  
  
          # audio = MP3('./'+'kurz-kacken.mp3')
  
          # a = audio.info.length
  
          voice.play(discord.FFmpegPCMAudio('./'+'kurz-kacken.mp3'),
  
                     after=lambda e: print("Song done!"))
  
          voice.source = discord.PCMVolumeTransformer(voice.source)
  
          voice.source.volume = 0.07
  
          # time.sleep(a)
  
          await ctx.send(f'ended')
  
  
  
          if voice and voice.is_connected():
  
              await voice.disconnect()
  
  
  
  
  
  def setup(client):
  
      client.add_cog(Soundboard(client))

• What transcoding services can people recommend ? [closed]

  3 mai 2013, par Adrian Lynch

  A client of mine needs to accept a bunch of different video files and convert them to FLV. My experience with FFMEG on a previous project has highlighted that there will be some troublesome files.

  Depending on the price my client will pay for a professional service.

  What are people using and how are you finding the service ?

  Thanks.

• Is encoding and streaming images into a video in under 30 ms realistic at all ?

  25 septembre 2020, par Hamza Ghizaoui

  So, a client camera would be sending 20 FPS 4000 x 3000 pixel images per second.

  


  The client want it to be streamed in under 30 ms upon receiving via a web-browser with a 1920 x 1080 resolution .

  


  Here is how we approached the problem :

  


  Image received => openCV resizes it to 1920 x 1080 => image piped to FFMPEG => ffmpeg encode it to H.264 using Nvec hardware acceleration => FFMPEG sends it via UDP-packets to a Node.js server => the Node.js server serves it to client (using React as a front-end there)

  


  The encoding time requires circa 12 ms using my best options while keeping the client quality standards.

  


  Downsizing the image requires 10 ms - this leaves circa 8 ms for the rest

  


  Is it doable at all or should I look for another approach ?
