• Evolution #4277 : Pouvoir utiliser InnoDB à la place de MyISAM (patch)

  18 septembre 2019

  Une vieille histoire : #2727
  Sachant que Fulltext est pris en compte sur Innodb, je vois pas trop ce qui nous retiendrait à utiliser MyISAM en fait encore (à part l’espace disque ?).
  Innodb semble être devenu la norme sous mysql.

• How to create a queue system with a discord.py bot

  20 août 2024, par Zamv

  I'm trying to create a bot with discord.py.

  


  Also, I'm a beginner, so I'll be interested in what I can improve and any errors there are.

  


  I've been stuck on trying to create this queue system for songs, the bot was working perfectly fine and played some urls before I implemented the play_next function. Now it doesn't even play the first song, even if it sends confirmation messages both in the terminal that in the discord channel. I know that the code might be a little confusing.

  


  I wrote two main functions : "play_next" to play the next song in the queue and "play", the main command. Here is my play_next function :

  


  async def play_next(self,ctx):
        if not ctx.voice_client.is_playing: #(don't know if this is correct as I also check if the bot isn't                     playing anything in the play function)
            
            if self.song.queue: 
                next_song = self.song_queue.pop(0) #deleting the first element of the queue, so if we have (song_0, song_1 and song_2) the bot should delete (song_0) making in fact song_1 the "next" song_0
                try:
                    ctx.voice_client.play(discord.FFmpegPCMAudio(next_song), 
                                          after=lambda e: self.bot.loop.create_task(self.play_next(ctx))) #Not gonna lie here, i asked chat gpt for this line, it should make the bot automatically play the next song one after another, correct me if I am wrong

#this is not important
                    embed = discord.Embed(
                        title="Song",
                        description=f"Now playing {next_song}",
                        color = 0x1DB954
                    )
                    await ctx.send(embed=embed)
                except Exception as e:
                    print(f"Error playing the next song: {e}")

            else:
                await ctx.voice_client.disconnect()  # disconnecting from the voice channel if the queue is empty
                print("Disconnected from the voice channel as the queue is empty.")


  


  I think that the main problem of my bot is the play_next function, but here it is my "play" function :

  


      @commands.command(pass_context=True)
    async def play(self, ctx, url: str):  
        if ctx.author.voice:  # first checking if the user is in a voice channel
            if not ctx.voice_client: #then checking if the bot is already connected to a voice channel
                channel = ctx.message.author.voice.channel 
                try:
                    await channel.connect()  #then joining
                    print("I joined the voice channel!")
                except Exception as e:
                    print(f"Failed to connect to the voice channel: {e}")
                    return

            song_path = f"song_{self.song_index}.mp3" #note, im using cogs, i declared self.song_index with the value of 0 
            self.song_index += 1 #i thought that this was the easiest way of creating a new file for each song

            ydl_opts = {
                'format': 'bestaudio/best',
                'postprocesors': [{
                    'key': 'FFmpegExtractAudio',
                    'preferredcodec': 'mp3',
                    'preferredquality': '192',
                }],
                'outtmpl': song_path
            }
            try:
                with youtube_dl.YoutubeDL(ydl_opts) as ydl:
                    print("Starting download...")
                    ydl.download([url]) #this is where it should download the song provided by the url
                    print("Download finished.")
            except Exception as e:
                await ctx.send(f"Failed to download the song: {e}")
                return

#i think that the next two if statements are the main threats
            if os.path.exists(song_path): #if there is atleast 1 song in the queue
                self.song_queue.append(song_path) #append the next one
                embed = discord.Embed(
                    title="Added to Queue!",
                    description = f"{url} has been added to the queue.",
                    color=0x33ff33
                )
                await ctx.send(embed=embed)


                if not ctx.voice_client.is_playing(): #checking if the bot is already playing something, don't know if i should put this if statement here
                    print("Starting playback...")
                    await self.play_next(ctx) #if nothing is playing, then the bot should play the next song



            else:
                await ctx.send("Failed to download or find the audio file.")

        else:
            embed = discord.Embed(
                title="❌You must be in a voice channel",
                color=0xff6666
            )
            await ctx.send(embed=embed)


  


• Save StreamTitle tag in recording

  29 décembre 2022, par jarno

  Some streams have StreamTitle tag set and it changes from time to time. Is that information send only when it changes in the stream ? For example in this stream StreamTitle is used to tell the artist and the name of current song :

  


  ffprobe -v error -show_entries format_tags http://st.downtime.fi/sun.mp3


  


  Is the StreamTitle tag exclusive to MP3 streams ? Can one have it in Opus streams as well ?

  


  Can such information be added to the output file created when recording the stream by ffmpeg for example, to be able to see which song is playing when playing the recording later ? Could another tag be used to tell program name which may also alter in time ?
