• Discord.py music_cog, bot joins channel but plays no sound

  20 juin 2021, par Ozzy

  I have started using python a week ago or so. I have watched all the related videos on YT and checked google pages etc. But still no luck. My bot perfectly joins to the voice channel and when i use play it downloads and presumebly starts the play function but there is no sound or anything, it just joins and waits 1-2 mins then leaves with timeout error.

  


  from discord.ext import commands

  I enabled logs to be sure, when it connects there's just that info :

  


  INFO:discord.voice_client:Connecting to voice... | INFO:discord.voice_client:Starting voice handshake... (connection attempt 1)

  


  I have also checked FFMPEG and its Path, tried different codes and methods but even though they work there is no sound. Also I installed discord.py[voice] too.

  


  I appreciate help already, thanks.

  


• Adding background audio in FFMPEG, but quieting it if there is sound in another channel

  9 septembre 2021, par Connor Bell

  I'm appending several videos together with FFMPEG. Some of these videos have accompanying audio, and some do not.

  


  I'd like to add music in the background, and have found out how to do so from here. However, I'd like the background music to be (let's say 80%) quieter if there is already audio in that video. Note that all videos have a null audio track, so just checking for the existence of an audio track isn't sufficient.

  


  My current process is :

  


  

  • Take source videos, add a null audio source and upscale (The null audio source is required for ffmpeg-concat to work due to a bug, I think)

  


  • Combine the videos using ffmpeg-concat

  


  


  Preferably, adding the background music should be the third step, as splitting the background music prior to combining the videos sounds more complex, but I may be wrong.

  


• My discord bot (python) isn't connecting to voice channel

  24 juin 2023, par BeanieYi

  My discord bot for some reason is not connecting to my voice channel when I type
 !play some url ... My bot is running because I've ran other tests on it. No error messages show up, so I'm lost as to why it's not working. This is the part of the code where it commands to bot to connect

  


      async def play_song(self, ctx):
        """
        Function plays music. Checks if user in voice channel
        """
        if len(self.queue) > 0:
            self.play = True
            url = self.queue[0][0]["source"]

            if self.vc is None or not self.vc.is_connected():   # If not in voice channel
                self.vc = await self.queue[0][1].connect()  # Wait until user joins channel
                if self.vc == None: # If user doesn't join channel, quit
                    await ctx.send("Could not connect D:")
                    return  
            else:
                await self.vc.move_to(self.queue[0][1]) # Moves bot to channel user is in

            self.queue.pop(0) 
            self.vc.play(discord.FfmpegPCMAudio(url, **self.ffmpeg_options), after=lambda e: self.next_song()) 
        else:
            self.play = False


  


  I added the following code below because this was the "new" method for cog, but it didn't yield any results for me. I also made sure my bot had permission on Discord to join channels and talk.

  


  async def setup(bot):
    await bot.add_cog(Event(bot))
