• How to make FFMPEG faster in general ? [closed]

  26 mars 2021, par GitM

  I convert regulary my video files to current codecs, to keep them available for most of the (currently used) devices.

  


  I use this to convert video files for apple tv :
ffmpeg -i video_file.abc -c:v libx265 -crf 27 -c:a aac -b:a 128k -tag:v hvc1 video_file_updatedt.mp4

  


  ... and this to convert audio files to ogg :
ffmpeg -i audio_file.abc -c:a libvorbis -q:a 4 audio_file_updated.ogg

  


  but it consumes 100% of my six core CPU (max. 3.4GHz) an took hours.

  


  Is there a smart way to speed this up and reduce CPU usage at the same time ?
Should i switch to another OS like Linux, one with better usage of my CPU ?

  


• Error for command not found, Discord bot in Python

  12 mars 2024, par Skely

  I followed a tutorial for making a discord bot and every time I type in a command I get the error message :

  


  discord.ext.commands.errors.CommandNotFound: Command "play" is not found

  


  It runs and shows to be online in my Discord server, I have given it every permission know to man, and checked through multiple times in my code to see if I find something wrong. But I don't see anything that can be changed or something that can fix it. I am in desperate need for help.
Thanks alot in advance !!

  


  This is my files and code :

  


  main.py

  


  import discord

from help_cog import help_cog
from music_cog import music_cog

bot = commands.Bot(command_prefix="?", intents=discord.Intents.all())

bot.remove_command("help")

bot.add_cog(help_cog(bot))
bot.add_cog(music_cog(bot))

bot.run(os.getenv("TOKEN"))

• error on Heroku application log after deployment

  30 juin 2021, par SDB PROGRAM LEARNER

  I had made a discord bot and deploy it to Heroku in this bot I can play youtube songs normally but after deploying on Heroku it gives me errors on application logs when I am trying to play my song

  


  My code :-

  


  import discord,requests, sys, webbrowser, bs4
import youtube_dl
import os
from dotenv import load_dotenv
import ffmpeg
from discord.ext import *
from discord.ext import commands
from discord.ext.commands import Bot
from discord.voice_client import VoiceClient
import asyncio
@client.command(pass_context=True)                      #====================================Join
async def join(ctx):
    channel = ctx.author.voice.channel
    await channel.connect()
@client.command()                                         #==================================Play
async def play(ctx, url:str):
    song_there = os.path.isfile("song.mp3")
    try:
        if song_there:
            os.remove("song.mp3")
            player.clear()
    except PermissionError:
        await ctx.send("Wait for the current playing music end or use the 'stop' command...")
        return
    await ctx.send("Getting everything ready, playing audio soon, depends on your internet speed...")
    print("Someone wants to play music let me get that ready for them...")
    voice = discord.utils.get(client.voice_clients, guild=ctx.guild)
    ydl_opts = {
        'format': 'bestaudio/best',
            'postprocessors': [{
            'key': 'FFmpegExtractAudio',
            'preferredcodec': 'mp3',
            'preferredquality': '192',
        }],
    }
    with youtube_dl.YoutubeDL(ydl_opts) as ydl:
        ydl.download([url])
    for file in os.listdir("./"):
        if file.endswith(".mp3"):
            os.rename(file, 'song.mp3')
    voice.play(discord.FFmpegPCMAudio("song.mp3"))
    
    voice.volume = 100


  


  It works properly on localhost from vscode

  


  but when I trying to use this after deployment on Heroku it gives me the error below
