• How to make a bot available to multiple users on blocking operations ? python, aiogram, pytube, ffmpeg

  27 février 2023, par Tony Reznik

  I'm trying to deal with multithreading and asynchrony, but I can't figure out how to deal with this situation.

  


  There is a telegram bot that downloads videos from YouTube and cuts only the first minute of the video into a separate file. Pytube and ffmpeg are used. The second bot user does not receive any response from the bot while the tasks of the first one are running. How to deal with such difficulties ?

  


  import subprocess

from aiogram import Bot, Dispatcher, types
from aiogram.utils import executor
from pytube import YouTube
import time

API_TOKEN = 'tkn'

bot = Bot(token=API_TOKEN)
dp = Dispatcher(bot)

video_folder = 'video/'


@dp.message_handler()
async def start_convert(message: types.Message):
    url = message.text
    yt = YouTube(url)

    await message.reply('accepted')

    video_name = time.strftime("%d-%m-%Y-%H-%M-%S") + '.mp4'

    video = yt.streams.get_highest_resolution()
    video.download(video_folder, filename=video_name)

    await message.reply('downloaded')

    subprocess.call(['ffmpeg', '-hide_banner', '-loglevel', 'error', '-i', f'{video_folder}{video_name}',
                     '-ss', '0', '-c:v', 'libx264', '-c:a', 'aac', '-b:v', '5M', '-to', '60',
                     f'{video_folder}1_min_{video_name}'])

    await message.reply('trimmed')

if __name__ == '__main__':
    executor.start_polling(dp, skip_updates=True)



  


  This is a code template.
In the current form, I want to understand how to implement the task correctly.

  


• Writing metadata (Artist Name, Song Title, Year, Album, Duration, Genre) to mp3/m4a audio file using youtube-dl (subsequent AtomicParsely error)

  10 décembre 2016, par IRNotSmart

  I am extracting audio only from youtube videos using youtube-dl. I would like to write the metadata (i.e. Artist Name and Song Title, Year, Album, Duration, Genre) into the mp3/m4a file after downloading. My attempt to accomplish this starts with this code :

  @echo off
  
  youtube-dl --format m4a/mp3 --youtube-skip-dash-manifest --embed-thumbnail -o "%%(title)s.%%(ext)s" --metadata-from-title "%%(artist)s - %%(title)s" --add-metadata 2Y6Nne8RvaA
  
  pause

  This code produces the following output :

  [youtube] 2Y6Nne8RvaA: Downloading webpage
  
  [youtube] 2Y6Nne8RvaA: Extracting video information
  
  [youtube] 2Y6Nne8RvaA: Downloading thumbnail ...

  [fromtitle] parsed artist: Kungs vs Cookin' on 3 Burners
  
  [ffmpeg] Adding metadata to 'Kungs vs Cookin' on 3 Burners - This Girl.m4a'
  
  ERROR: AtomicParsley was not found. Please install.
  
  Press any key to continue . . .

  As you can see, I am able to successfully able to add a few of the tags from the video, but not all of them and the Year is royally screwed up.
  

  What is this AtomicParsely error and how do I remedy it ? Do I need this program to correctly add all the Metadata to the file that I want, or can this be accomplished in another way ?

  Referencing Steven Penny’s post, FFmpeg metadata not showing in Windows ?, is solving this problem as simple as using an ffmpeg command ?

  When I do a google search for this song, the first link that shows is the exact link I’m using on YouTube, and the search shows pertinent metadata (see below). I’m not sure if this data is input manually by users, or if Google mined this from the video :
  

  I admit that I’m new to using youtube-dl and ffmpeg, but with the help of the commenters on StackOverflow, I’m learning more each day. This post is a follow-up to my previous question : Downloading YouTube to mp3 and writing metadata (artist/song title) to mp3 file using youtube-dl

• Anomalie #3198 (Nouveau) : Impossible de s’authentifier quand le dossier /tmp n’est pas accessible...

  3 avril 2014, par Goulven Champenois

  Quand le dossier "tmp/" n’est pas accessible en écriture, toute tentative de login par le formulaire d’authentification (du dossier "ecrire/") renvoie "Login : accès interdit", même quand le login et le mot de passe sont corrects.

  1. La possibilité de s’identifier ne devrait pas être dépendante d’une telle condition
  2. Le message d’erreur devrait être du type "Configuration du serveur incorrecte : le dossier tmp/ n’est pas accessible en écriture". Si on craint pour la sécurité, n’afficher ce message que si le login/mot de passe sont corrects.
