• Audio Downloader from YouTube with youtube-dl and ffmpeg [closed]

  22 janvier 2021, par Um9vdAo

  I am trying to make an audio downloader with youtube-dl and ffmpeg which will :
  

  


  


  

  1. Download the best format of audio available on YouTube
     

  


  2. Embed thumbnail in the file.

  


  3. Convert the file to mp3.

  


  4. Delete everything from the folder except the converted mp3 file.
     

  


  


  


  Below is the code I've come up with :

  


  @echo off
cls
set /p playlist="Enter YouTube Link: " 
youtube-dl --cookies cookies.txt -f bestaudio[ext=m4a] -i --write-thumbnail --embed-thumbnail --max-sleep-interval 30 --min-sleep-interval 10 -o "%%(title)s.%%(ext)s" %playlist% --exec "ffmpeg -i {} -codec:a libmp3lame -qscale:a 0 {}.mp3 && del {}"


  


  The issues I've been facing with my code :

  


  

  1. The converted file is not renamed correctly. It's named Filename.m4a.mp3 where I want it to be named Filename.mp3
     

  


  2. Video thumbnail is saved as Filename.jpg and youtube-dl creates a file named cookies.txt. Those are not deleted automatically.

  


  3. Lastly, this error shows up :

  


  


  


  [swscaler @ 00000143e0a4ffc0] deprecated pixel format used, make sure you did set range correctly
[mp3 @ 00000143e09f0340] Frame rate very high for a muxer not efficiently supporting it.
Please consider specifying a lower framerate, a different muxer or -vsync 2

  


  


  I'd really appreciate it if you helped me fix those issues. Thanks !

  31 janvier 2020, par robotiaga

  I created script which one downloading video and sound from Youtube, and after that merging sound and video with ffmpeg, i wondering is another way to make same result but in faster way ? Because this script takes about 7 min depends on Video quality and duration. My code bellow :

  from pytube import YouTube
  
  import sys
  
  import ffmpeg
  
  import os
  
  
  
  
  
  class Downloader(YouTube):
  
  
  
      def __init__(self, link):
  
          self.link = YouTube(link)
  
          self.hq = []
  
          self.best_video = []
  
          self.best_sound = []
  
  
  
  
  
      def stream_objects(self):
  
          q = [self.hq.append(x) for x in self.link.streams.all()]
  
          self.best_video.append(str(self.hq[1]).split()[1].split('\"')[1])
  
          self.best_sound.append(str(self.hq[-1]).split()[1].split('\"')[1])
  
          return self.best_video, self.best_sound
  
  
  
      def downloady(self):
  
          vid = self.link.streams.get_by_itag(str(self.best_video).strip("['']"))
  
          audio = self.link.streams.get_by_itag(str(self.best_sound).strip("['']"))
  
          self.vid_title = (f"{vid.title}"+".mp4")
  
  
  
          vid.download(filename='video')
  
          audio.download(filename='audio')
  
          print('Downloaded, Now Starting Merge \n\n\n\n\n')
  
          print(f'{self.vid_title}'+'\n')
  
  
  
      def merge(self):
  
          ffmpeg.output(ffmpeg.input('video.mp4'), ffmpeg.input('audio.webm'), self.vid_title).run()
  
          os.remove('video.mp4')
  
          os.remove('audio.webm')
  
  
  
  
  
  
  
  if __name__=='__main__':
  
      a = Downloader(link = sys.argv[1])
  
      a.stream_objects()
  
      a.downloady()
  
      a.merge()

  OKE UPDATE :
  Now code looks like that..Second problem is slow downloading mp4 files from YouTube server, i have 10Gb/s internet. Good connection with YT servers, but why so poor downloading ? ? ? :)

  from pytube import YouTube
  
  import sys
  
  import ffmpeg
  
  import os 
  
  import subprocess
  
  
  
  class Downloader(YouTube):
  
  
  
      def __init__(self, link):
  
          self.link = YouTube(link)
  
          self.hq = []
  
  
  
  
  
      def stream_objects(self):
  
          self.best = self.link.streams.filter(file_extension='mp4')
  
          q = [self.hq.append(x) for x in self.best.all()]
  
          self.best_vid_itag = str(self.best.all()[1]).split()[1].split('\"')[1]
  
          self.best_audio_itag = str(self.best.all()[-1]).split()[1].split('\"')[1]
  
  
  
      def downloader(self):
  
          vid = self.link.streams.get_by_itag(self.best_vid_itag)
  
          aud = self.link.streams.get_by_itag(self.best_audio_itag)
  
          print('Donwloading Video file...\n')
  
          vid.download(filename='video')
  
          print('Video file downloaded... Now Trying download Audio file..\n')
  
          aud.download(filename='audio')
  
          print('Audio file downloaded... Now Trying to merge audio and video files...\n')
  
  
  
      def merger(self):
  
          lin = str(self.link.title).rstrip()
  
          lin2 = (lin+'.mp4')
  
          subprocess.run(f'ffmpeg -i video.mp4 -i audio.mp4 -c copy "{lin2}"', shell=True)
  
          os.remove('video.mp4')
  
          os.remove('audio.mp4')
  
          print('Done....\n')
  
  
  
  if __name__=='__main__':
  
      a = Downloader(link = sys.argv[1])
  
      a.stream_objects()
  
      a.downloader()
  
      a.merger()
