• Recognize start of piano music in an MP3 file which starts with a spoken introduction, and remove spoken part, using Python

  22 août 2020, par user3716846

  I have a number of .mp3 files which all start with a short voice introduction followed by piano music. I would like to remove the voice part and just be left with the piano part, preferably using a Python script. The voice part is of variable length, ie I cannot use ffmpeg to remove a fixed number of seconds from the start of each file.
Is there a way of detecting the start of the piano part and then know how many seconds to remove using ffmpeg or even using Python itself ?.
Thank you

  


• discord.py music bot can't play next song

  6 décembre 2020, par bork

  I'm making a discord music bot using ffmpeg and youtube-dl. I have a premade playlist of urls that would play the list of songs once a user chooses it.
  
this is my code for playing the audio

  


  ydl_opts = {
            'format': 'bestaudio', 
            'noplaylist':'True',
            'youtube_include_dash_manifest': False
            }
FFMPEG_OPTIONS = {
            'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5',
            'options': '-vn'
            }

songs = url[playlist]
dur_min = 0
pre_dur_sec = 0
with YoutubeDL(ydl_opts) as ydl:
    for i in songs:
        info = ydl.extract_info(i, download = False)
        dur = info['duration']
        playlist_songs.append(info)

playlist_songs_copy = playlist_songs.copy()
for i in playlist_songs_copy:
    info = playlist_songs.pop(0)
    URL = info['formats'][0]['url']
    player = FFmpegPCMAudio(URL, **FFMPEG_OPTIONS)
    q.append(player)
    q_playlist.append(playlist)

if not voice.is_playing():
    source = q.pop(0)  
    playlist = q_playlist.pop(0)
    dur_min = duration_min.pop(0)
    dur_sec = duration_sec.pop(0)  
    voice.play(source, after = lambda e: play_next(ctx, source))      
    voice.is_playing()
    await ctx.send(f'```nim\n*Now Playing:*\nplaylist {playlist}: {name[playlist]}\n\n{content[playlist]}\n\ntotal duration: {dur_min}:{dur_sec}```')


  


  and this is my code for playing the next song

  


  def play_next(ctx, source):
    voice = get(client.voice_clients, guild = ctx.guild)
    if len(q) >= 1:
        try:
            del combine_q[0]
            source = q.pop(0)
            playlist = q_playlist.pop(0)
            dur_min = duration_min.pop(0)
            dur_sec = duration_sec.pop(0)

        except:
            pass

        voice.play(source, after = lambda e: play_next(ctx, source))
        try:
            asyncio.run_coroutine_threadsafe(ctx.send(f'```nim\n*Now Playing:*\nplaylist {playlist}: {name[playlist]}\n\n{content[playlist]}\n\ntotal duration: {dur_min}:{dur_sec}```'), client.loop)
        
        except:
            asyncio.run_coroutine_threadsafe(ctx.send('```nim\nPlaying the next song...```'), client.loop)
        
    else:
        time.sleep(30) 
        if not voice.is_playing():
            asyncio.run_coroutine_threadsafe(voice.disconnect(), client.loop)
            asyncio.run_coroutine_threadsafe(ctx.send("```nim\nNo more songs in queue.```"),client.loop)
            voice.is_paused()


  


  Up till today, it's been working fine. But I was using the bot just now and instead of playing the song and sending the message "Playing the next song..." as usual, it just stopped and spammed the message for about 30 times before it disconnected. When I checked the logs, it showed
socket.send() raised exception
, which was also spammed in the terminal. When I tried making the bot reconnect, it joined my voice channel but didn't respond to any commands and would keep making the discord "connecting" noise. It wouldn't even leave with my .leave command unless I completely turned it off via the script.

  


  The same connecting problem would continue even after I reran the script and would only stop after I restarted my VS Code which is really odd...

  


  After some testing I found out that as of now, the bot is only able to play two songs before breaking. I really need help as this just happened randomly and I'm unable to find anything online about the problem.

  


• Discord,py ffmpeg and youtube_dl music bot isnt playing playlists

  5 décembre 2020, par CubacraftLP

  Hello Stackoverflow Community,
I got the following problem :

  


  Im using this code for playing music with my discord.py bot :

  


  @bot.command()
async def activate(ctx, url):
    
    YDL_OPTIONS = {'format': 'bestaudio', 'noplaylist':'True'}
    FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
    voice = get(bot.voice_clients, guild=ctx.guild)

    if not voice.is_playing():
        with YoutubeDL(YDL_OPTIONS) as ydl:
            info = ydl.extract_info(url, download=False)
        URL = info['formats'][0]['url']
        voice.play(FFmpegPCMAudio(URL, **FFMPEG_OPTIONS))
        voice.is_playing()

        else:
            await ctx.send("Already playing song")
            return


  


  but if im now pasting a playlist link, im geting the following error :

  


  Ignoring exception in command activate:
Traceback (most recent call last):
  File "C:\Users\\PycharmProjects\MusicBot\venv\lib\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "C:/Users//PycharmProjects/MusicBot/main.py", line 47, in activate
    URL = info['formats'][0]['url']
KeyError: 'formats'

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

Traceback (most recent call last):
  File "C:\Users\\PycharmProjects\MusicBot\venv\lib\site-packages\discord\ext\commands\bot.py", line 903, in invoke
    await ctx.command.invoke(ctx)
  File "C:\Users\\PycharmProjects\MusicBot\venv\lib\site-packages\discord\ext\commands\core.py", line 859, in invoke
    await injected(*ctx.args, **ctx.kwargs)
  File "C:\Users\\PycharmProjects\MusicBot\venv\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: KeyError: 'formats'



  


  is there a way to fix it and make my bot play playlists ?
Thank you for your answers.
