• I have a m3u8 file where the individual files don't have any .ts format, Is there a way to cocnat them to a single mp4 file

  Here is a snippet of the m3u8 file

  


  #EXTM3U
#EXTINF:1,0

  This goes on for some 500 files. I am able to open the folder in vlc as a playlist but it is just a collection of 500 files that play one after the another. I checked online and found that ffmpeg can concatenate a m3u8 file to a mp4. That unfortunately did not work. After trying a few different syntaxes that I found on different forums which also did not work, I tried "ffplay" on the file name which once again gave the same error message as before - Invalid data found when processing input:=    0B f=0/0

  


  So this made me believe perhaps ffmpeg is unable to open the file while vlc is able to. Any way to combine these files to a single file is appreciated

  


• PyInstaller —noconsole still shows the console after running the app

  23 septembre 2020, par Kiren78

  I've built an app to download and play sound everytime someone inserts or removes USB drive from PC.
  
Code :

  


  from playsound import playsound
from win10toast import ToastNotifier
from time import sleep
from typing import Callable
import threading
import os
import youtube_dl
import win32file


def play_audio():
    try:
        path = os.getcwd() + "\\audio.mp3"
        ydl_opts = {
            'format': 'bestaudio/best',
            'postprocessors': [{
                'key': 'FFmpegExtractAudio',
                'preferredcodec': 'mp3',
                'preferredquality': '192',
            }],
            'outtmpl': path
        }

        with youtube_dl.YoutubeDL(ydl_opts) as ydl:
            ydl.download(['https://www.youtube.com/watch?v=_0HTwQjMr9k'])

        playsound(path)
    except Exception as e:
        toast = ToastNotifier()
        toast.show_toast("RIP prank failed byq", "no ogolnie prank failed rip co jest?", duration=20)


def get_drives():
    drive_list = []
    drivebits = win32file.GetLogicalDrives()
    for d in range(1, 26):
        mask = 1 << d
        if drivebits & mask:
            drname = '%c:\\' % chr(ord('A') + d)
            t = win32file.GetDriveType(drname)
            if t == win32file.DRIVE_REMOVABLE:
                drive_list.append(drname)
    return drive_list


def watch_drives(on_change: Callable[[dict], None] = print, poll_interval: int = 1):
    def _watcher():
        global prev
        while True:
            drives = get_drives()
            if prev != drives:
                on_change(drives)
                play_audio()
                prev = drives
            sleep(poll_interval)

    t = threading.Thread(target=_watcher)
    t.start()
    t.join()


if __name__ == '__main__':
    prev = get_drives()
    watch_drives(on_change=print)


  


  I don't understand it but everytime the download starts and FFmpeg starts debugging everything (using youtube-dl) a couple of console windows appear for a fraction of a second and they immediately disappear. How can I TOTALLY disable the console so that even FFmpeg can't open it ?

  


  EDIT : Yes, I've already tried using --windowed and -w parameters in PyInstaller

  


• Enter individual folder(s) and execute PowerShell command

  5 octobre 2020, par WorldTeacher

  I have many folders with even more subfolders, and as posted in my first question

  


  


  How to create a powershell script / or windows .bat file for ffmpeg

  


  


  I want to encode all video files in the folders.
The Script I got from mklement0 works fine but lazy as I am, I was wondering if there was a way to tell the PowerShell to enter folder 1, go to subfolder_1, and execute the ps1 script (would be perfect if it executed in a new powershell instance), wait a certain time and go into subfolder_2

  


  Repeat until no more subfolders available.

  


  Is this possible ?

  


  Edit :
The Script I got :

  


  Get-ChildItem *.mkv | where BaseName -notlike '*`[encoded]' | foreach {
ffmpeg -i $_ -c:v libx265 -c:a copy -x265-params crf=25 "$($_.BaseName)[encoded].mkv"
pause
}


  


  


  What is the reason for the desire to process each subfolder in a separate instance of powershell.exe ? by Mathias R. Jessen

  


  


  Because I want to encode multiple folders at once to save some time.
If there is a way to execute the script in the same PowerShell (as far as my understanding goes, I can only encode one folder at one time if I use the same PowerShell instance)
