• 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.

  


• ffmpeg fluent live streaming to youtube not working

  18 octobre 2020, par Ricky

  I am learning how to using ffmpeg fluent and I am having trouble getting it to stream live to Youtube

  



  here is the command I have tried :

  



  let streamYT = (YTrtmpKey) => {
  var proc3 = new ffmpeg({ source: inputURL, timeout: 0 })
    .addOption('-vcodec', 'libx264')
    .addOption('-acodec', 'aac')
    .addOption('-crf', 26)
    .addOption('-aspect', '640:360')
    .withSize('640x360')
    .on('start', function(commandLine) {
    console.log('Query : ' + commandLine);
    })
    .on('error', function(err) {
    console.log('Error: ' + err.message);
    })
    .output('rtmp://a.rtmp.youtube.com/live2/' + YTrtmpKey, function(stdout, stderr) {
    console.log('Convert complete' +stdout);
  });
  }


  



  this doesn't throw any errors but also doesn't do anything

  


• 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
