• How to Extract Mp3 from M3u8 Native Audio stream in php using FFMPEG ?

  9 septembre 2023, par Narendhiran vignesh

  I'm trying to extract mp3 links from the cdn sites. But some of the links have m3u8 format. I cannot able to simply download mp3 songs from it. I tried using ffmpeg but i'm failing to do correctly. I simply want is to a piece of code to convert the m3u8 links into mp3 using ffmpeg in php and store in a folder and generate download link to the mp3 file.

  


  Thank You, Code for your reference.

• Hide ffmpeg's console window when running YoutubeDL in GUI application

  27 février 2021, par Božo Stojković

  I'm developing a basic application which can download YouTube videos. Throughout the development, I had several quirks, including issues with formats.

  



  I decided to use a hopefully foolproof format syntax that youtube-dl will happily download for me in almost any case.

  



  Part of my YoutubeDL options look like this :

  



  self.ydl_opts = {
    'format': 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best',
    'quiet': True,
    'progress_hooks': [self.ydl_progress],
    'outtmpl': None
}


  



  The outtmpl is inserted later on when output folder is chosen by the user.

  



  Since I'm using this format string, youtube-dl uses ffmpeg to merge(?) the audio and video if they are downloaded separately.

  



  When it does that, it opens very annoying console windows that capture the focus and interrupt other things I might be doing while the videos are downloading.

  



  My question is, how can I prevent ffmpeg or youtube-dl from creating those console windows from appearing, aka. how can I hide them ?

  



  EDIT :

  



  I'll provide bare bones script that reproduces the problem :

  



  from __future__ import unicode_literals
from PyQt4 import QtGui, QtCore
import youtube_dl, sys

def on_progress(info):
    print info.get("_percent_str", "Finished")

ydl_opts = {
    'format': 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best',
    'progress_hooks': [on_progress],
    'quiet': True,
    'outtmpl': "C:/Users/Raketa/Desktop/%(title)s.%(ext)s"
}

ydl = youtube_dl.YoutubeDL(ydl_opts)

class DownloadThread(QtCore.QThread):
    def __init__(self):
        super(DownloadThread, self).__init__()
        self.start()

    def __del__(self):
        self.wait()

    def run(self):
        print "Download start"
        ydl.download(["https://www.youtube.com/watch?v=uy7BiiOI_No"])
        print "Download end"

class Application(QtGui.QMainWindow):
    def __init__(self):
        super(Application, self).__init__()
        self.dl_thread = DownloadThread()

    def run(self):
        self.show()

def main():
    master = QtGui.QApplication(sys.argv)

    app = Application()
    app.run()

    sys.exit(master.exec_())

if __name__ == '__main__':
    main()


  



  2(?) consoles appear at start of each download and 1 longer lasting console appears when both video and audio are downloaded. When downloading longer videos, the last console becomes unbearable.

  



  Is it possible to get rid of those ?
