• Make Discord bot play sound from a direct url

  20 septembre 2020, par merctraider

  I want to make a discordpy bot that plays audio files from a specific link on the internet, rather than from a local directory. It seems that all the other examples use ytdl, but those are for video streaming sites. How should I go about doing this ?

  


      if(voice_channel != None):
        vc = await voice_channel.connect()

        vc.play(discord.FFmpegPCMAudio('http://website/001.mp3'), after=lambda e: print('done', e))
    else:
        await ctx.send("Join a voice channel first.")```


  


• Ruby - Threads and Dir[] arrays

  17 mars 2016, par Lewis909

  I have built a ruby script that creates folders, moves a file into that new folder and then invokes a system() call to trigger FFMPEG. I have now turned this into 4 threads so that I can do 4 concurrent transcodes at a time.

  Here is an example with 2 threads (minus folder structure creation and file move functions) :

  def transcode_process_1
  
  
  
   Dir["path/file/source/*.mxf"].each do |f|
  
  
  
     random_folder = #code for random folder creation
  
  
  
     file_move = #code to move .mxf file to random_folder for processing
  
  
  
     system("FFMPEG -i #{random_folder} command 2> /path/file/#{random_filename}.txt")
  
  
  
     sleep(2)
  
  
  
   end
  
  end
  
  
  
  def transcode_process_2
  
  
  
   sleep(3)
  
  
  
   Dir["path/file/source/*.mxf"].each do |f|
  
  
  
     random_folder = #code for random folder creation
  
  
  
     file_move = #code to move .mxf file to random_folder for processing
  
  
  
     system("FFMPEG -i #{random_folder} command 2> /path/file/#{random_filename}.txt")
  
  
  
     sleep(4)
  
  
  
   end
  
  end
  
  
  
  transcode_thread_1 = Thread.new{transcode_process_1()}
  
  transcode_thread_2 = Thread.new{transcode_process_2()}
  
  
  
  transcode_thread_1.join
  
  transcode_thread_2.join

  This iterates through the Dir "path/file/source/" and processes any.mxf files it finds. The issue I am having is that when both threads are running they are adding the same files into the array. This results in FFMPEG stating it cannot locate the file (this is because another thread has processed it and moved it to the temp folder) and creating superfluous folders and log files, basically just making it messy.

  My question is how would I go about making sure transcode_thread_2 does not process files that transcode_thread_1 has added to it array ? Is there a way I can get the function to check that the file in the array is still exists ? If it does then carry out the process, if not move on to the next file ?

  Thanks

• ffmpeg doesn't work in heroku using discord.py, how can i solve it ?

  20 septembre 2022, par empress

  I'm making a discord bot with python and it has a music cog. I've just hosted the bot, and everything works perfectly except this cog. Bassically, the problem is that even if the bot is ready with no errors, when I try to play something in one channel with the command !pl <search></search> the bot joins the channel, but it doesn't play anything.

  


  I have already add the BuildPacks to heroku (opus, ffmpeg, python) and all the requirements are ready (The music cog worked on my pc when i was building it).

  


  The output in terminal shows "discord.player : ffmpeg process 26 successfully terminated with return code of -11"

  


  I'll upload a few part of my code, which explains it at all.

  


  import discord

            self.music_queue.pop(0)
            self.vc.play(discord.FFmpegPCMAudio(m_url, **self.FFMPEG_OPTIONS), after=lambda e: self.play_next())
        else:

                    return

    @commands.command(name = "play", aliases = ["pl"])
    async def play(self, ctx, *args):
        query = " ".join(args)
        await ctx.send(f"Buscando en youtube según {query}...")
        member = ctx.author
        voice_channel = ctx.author.voice.channel
        if voice_channel is None:
            await ctx.send(f"you need to join a vc {member.mention} !!")
        elif self.is_paused
            self.vc.resume()
        else:
            song = self.search_yt(query)
            song_name = song.get("title")
            if type(song) == type(True):

            else:

                self.music_queue.append([song, voice_channel])
                await self.play_music(ctx)


  


  If anyone can help me I would appreciate it so much :(
