• Music bot returning errors at core.py and bot.py

  13 septembre 2021, par Loganox

  The code for the music bot I'm trying to write in python keeps returning an error with the following code :

  


  @bot.command(name='play_song', help='To play song')
async def play(ctx,url):
    
    #if not ctx.message.author.name=="Rohan Krishna" :
    #     await ctx.send('NOT AUTHORISED!')
    #     return
    if 1==1:#try :
        server = ctx.message.guild
        voice_channel = server.voice_client
        print("try 1 was a success")
        
        async with ctx.typing():
            filename = await YTDLSource.from_url(url, loop=bot.loop)
            #voice_channel.play(discord.FFmpegPCMAudio(executable="ffmpeg.exe", source=filename)) #ISSUE HERE
            print("try 2 was a success")
            voice = get(ctx.bot.voice_clients, guild=ctx.guild)
    
            #voice.play(discord.FFmpegPCMAudio('test.mp3'), after=your_check)
            #voice.source = discord.PCMVolumeTransformer(voice.source)
            #voice.source.volume = 0.5
        await ctx.send('**Now playing:** {}'.format(filename))
    if 1==0:#except:
        await ctx.send("The bot is not connected to a voice channel.")
        print("try 3 was unfortunately a success")


  


  It normally has a try/except function but I replaced it with if true and false statements to force it to run instead of breaking to determine the exact line of it breaking. The issue supposedly lies in

  


  voice_channel.play(discord.FFmpegPCMAudio(executable="ffmpeg.exe", source=filename)) #ISSUE HERE


  


  The error I get returned is :

  


  Traceback (most recent call last):
  File "C:\Users\heyin\anaconda3\lib\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "app2.py", line 75, in play
    voice.play(discord.FFmpegPCMAudio('test.mp3'), after=your_check)
  File "C:\Users\heyin\anaconda3\lib\site-packages\discord\player.py", line 225, in __init__
    super().__init__(source, executable=executable, args=args, **subprocess_kwargs)
  File "C:\Users\heyin\anaconda3\lib\site-packages\discord\player.py", line 138, in __init__
    self._process = self._spawn_process(args, **kwargs)
  File "C:\Users\heyin\anaconda3\lib\site-packages\discord\player.py", line 147, in _spawn_process
    raise ClientException(executable + ' was not found.') from None
discord.errors.ClientException: ffmpeg was not found.

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\heyin\anaconda3\lib\site-packages\discord\ext\commands\bot.py", line 939, in invoke
    await ctx.command.invoke(ctx)
  File "C:\Users\heyin\anaconda3\lib\site-packages\discord\ext\commands\core.py", line 863, in invoke
    await injected(*ctx.args, **ctx.kwargs)
  File "C:\Users\heyin\anaconda3\lib\site-packages\discord\ext\commands\core.py", line 94, in wrapped
    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: ClientException: ffmpeg was not found.


  


  I added the print statements to determine which lines were working so those can obviously be ignored. It seems to be working fine except for this, other commands in the bot are working appropriately.

  


• Fix TS File Audio Sync Issue Using FFMPEG

  23 juillet 2021, par Steve Brown

  I have a few .ts files which I've downloaded from the web that I want to chop up into smaller files. I'm using FFmpeg to do this, but each time, after about 3 minutes the video starts to fall behind and go out of sync with the audio.

  


  I've been experimenting with async and vsync and have gotten this far...

  


  ffmpeg -I test.ts -async 1 -map 0:1 -c:v copy -map 0:0 -channel_layout '5.1' -ss 01:00:12 -to 01:07:45 -y test.mp4

  


  The result is a file where the audio and video and in sync, but every few seconds the audio jumps. I assume this is because the audio has been trimmed to align with the video stream ?

  


  Does anyone know how I could get the video to align to the audio ? i.e. leave the audio as-is and drop frames from the video stream to keep aligned with the audio ?

  


• Discord.py ffprobe/avprobe and ffmpeg/avconv not found error

  20 juillet 2021, par Exd Craft

  Im hosting this discord bot using android device and the bot is used to play music using youtube_dl module, and when i launch the play music command, i got and error where ffprobe/avprobe and ffmpeg/avconv not found. I know how to solve this problem in pc but im still dont know how to fix this on android. For the test here, im using a music from soundcloud since its more faster to download the music.

  


  Here's the error message on the terminal
