• OpusError while using ffmpeg library in discord.py

  18 avril 2021, par The Assignment Nerd

  While playing a local file or youtube audio, I get OpusError: invalid argument error

  


  The play command looks like :

  


  # bot.py

from discord.ext import commands
from dotenv import load_dotenv
from models import *

@bot.command()

    user=ctx.author
    voice_channel=user.voice.channel
    channel=None
    # only play music if user is in a voice channel
    if voice_channel:
        # grab user's voice channel
        channel=voice_channel.name
        await ctx.send('User is in channel: '+ channel)
        # create StreamPlayer
        vc = await voice_channel.connect()

        voice = discord.utils.get(bot.voice_clients, guild=ctx.guild)
        print(0)
        if not voice.is_playing():
            print("1")
            with YoutubeDL(YDL_OPTIONS) as ydl:
                info = ydl.extract_info(url, download=False)
                print(2)
            URL = info['formats'][0]['url']
            print(3)
            voice.play(discord.FFmpegPCMAudio(URL, **FFMPEG_OPTIONS))
            print(4)
            voice.is_playing()
            print("Strated playing")
        else:
            await ctx.send("Already playing song")
            return
    else:
        await ctx.send('User is not in a channel.')

• extract date and LUFS from a file with script

  21 août 2021, par sJoss

  I am using

  


  for i in *.mp4; do echo "$i:"; ffmpeg -i "$i" -map 0:a -af ebur128=framelog=verbose -f null - 2>&1 | awk '/I:/{print $2}'; done


  


  to extract LUFS and then using

  


  for i in *.mp4; do ffprobe -v quiet -select_streams v:0 -show_entries format=filename:stream_tags=creation_time -of default=noprint_wrappers=1:nokey=1 "$i"; done


  


  to extract date of creation of mp4 files.

  


  How can I have those both command as a sequence or a script file so that I run the command only once, and I get both of those command run.
I want to get the output as ;

  


  File name
LUFS
Creation date


  


  It will be great if the command will also export all outputs in a text file.

  


  Please help.
Thank you in advance !!

  


• How To Make A Music Command Discord.py

  I'm trying to make a music bot, but it just doesn't seem to work. Here's what I have so far.

from async_timeout import timeout
from discord.ext import commands

bot = commands.Bot(command_prefix='+')

@bot.event
async def on_ready():
    print('Logged in as:\n{0.user.name}\n{0.user.id}'.format(bot))

youtube_dl.utils.bug_reports_message = lambda: ''

ytdl_format_options = {
    'format': 'bestaudio/best',
    'restrictfilenames': True,

}

class YTDLSource(discord.PCMVolumeTransformer):
    def __init__(self, source, *, data, volume=0.5):
        super().__init__(source, volume)
        self.data = data
        self.title = data.get('title')
        self.url = ""

    @classmethod
    async def from_url(cls, url, *, loop=None, stream=False):

            # take first item from a playlist
            data = data['entries'][0]
        filename = data['title'] if stream else ytdl.prepare_filename(data)
        return filename

@bot.command(name='join', help='Tells the bot to join the voice channel')

    if not ctx.message.author.voice:
        await ctx.send("{} is not connected to a voice channel".format(ctx.message.author.name))

        channel = ctx.message.author.voice.channel
        await channel.connect()
        await ctx.send(f'Joined channel `{channel}`')

    voice_client = ctx.message.guild.voice_client
    if voice_client.is_connected():

        await voice_client.disconnect()
        await ctx.send(f'Left channel `{channel}`')
    else:
        await ctx.send("The bot is not connected to a voice channel.")

@bot.command(name='play', help='To play song')
async def play(ctx,url):
    try :
        server = ctx.message.guild
        voice_channel = server.voice_client

        async with ctx.typing():
            filename = await YTDLSource.from_url(url, loop=bot.loop)
            voice_channel.play(discord.FFmpegPCMAudio(executable="ffmpeg.exe", source=filename))
        await ctx.send('**Now playing:** {}'.format(filename))
    except:
        await ctx.send("The bot is not connected to a voice channel.")


  


  I have installed PyNaCl and all that stuff and my leave and join commands are working but my play command isnt. It says that it's not connected to a channel but it clearly is.
