• Youtube-dl cannot read various set on batch script

  18 novembre 2019, par Al UrbaseR Blongtous

  I created an batch-script that positioned with youtube-dl and ffmpeg. I set several set to put URL and Video/Audio ID. Here my script that I simplified

  @echo off
  
  cd /d %root%\YT
  
  color 0a
  
  title Youtube Downloader
  
  setlocal enableDelayedExpansion
  
  set q=^"
  
  color 0a
  
  
  
  :submenu
  
  echo Please enter URL.
  
  set /p f1="URL: " 
  
  echo Checking ID...
  
  youtube-dl -F %f1%
  
  ping localhost -n 2 >nul
  
  goto menu
  
  
  
  :menu
  
  echo.
  
  echo Script created by UrbaseR
  
  echo ___________________________________________________________
  
  echo.
  
  echo                          MENU
  
  echo ___________________________________________________________
  
  echo OS Windows - %ComputerName%
  
  echo.
  
  echo M E N U
  
  echo Press 1 to Download Best version 
  
  echo Press 2 to Download Custom version + convert
  
  echo Press 3 to Exit
  
  
  
  set /p you=">"
  
  if %you%==1 goto 1
  
  if %you%==2 goto 2
  
  if %you%==3 goto 3
  
  
  
  cls
  
  echo *********************************
  
  echo Sorry invalid number!
  
  echo *********************************
  
  ping localhost -n 2 >nul
  
  goto menu
  
  
  
  :1
  
  echo Downloading...
  
  youtube-dl -f best %f1%
  
  echo.
  
  echo Done
  
  ping localhost -n 2 >nul
  
  cls
  
  goto submenu
  
  
  
  :2
  
  set /p id1="Insert Video ID: "
  
  set /p id2="Insert Audio ID: "
  
  echo Downloading Video..
  
  youtube-dl -f %id1% -ciw -o "vid.%(ext)s" -v --write-sub %f1%
  
  echo.
  
  echo Video Done
  
  ping localhost -n 2 >nul
  
  echo Downloading Audio..
  
  youtube-dl -f %id2% -ciw -o "aud.%(ext)s" -v %f1%
  
  echo.
  
  echo Audio Done
  
  ping localhost -n 2 >nul
  
  echo Converting Video
  
  ffmpeg -i "vid.%(ext)s" -i "aud.%(ext)s" -c:v copy -c:a aac -strict experimental "input.mkv"
  
  echo Converting Done
  
  ping localhost -n 4 >nul
  
  cls
  
  goto submenu
  
  
  
  :3
  
  exit

  First and third option execute successfully. Second option will appear the message like this :

  Usage : youtube-dl [OPTIONS] URL [URL...]
  youtube-dl : error : You must provide at least one URL.

  Type youtube-dl —help to see a list of all options.

  Note : Since I stuck on first and second stage of youtube-dl, ffmpeg may not work (I have not tested it yet).

  Can you help me ?

• Legal issues in shipping apps based on Electron framework (libffmpeg)

  21 juin 2021, par Manmohan Singh

  We're in the process of building and deploying a desktop based app on electron v 12.0.7. It'll be a (free) commercial software deployed to 2-3M users worldwide.
Recently our legal team enquired about the proprietary codecs bundled with chromium and I thought the best way to confirm this would be to reach out here.

  


  So, here're specific things that I need help with :

  


  


  1. Are we shipping chromium with proprietary codecs ? If yes, what are potentially contentious codecs that come by default in chromium bundled with electron v 12.0.7 ?

     


  


  2. Is there any documentation around how the electron team builds chromium (with what flags) ?

     


  


  3. Is the default libffmpeg.dylib/dll bundled with electron building ffmpeg with support for things like H.264 and MP3 codecs ?

     


  


  4. I noticed there are libffmpeg binaries available with each electron build, e.g. https://github.com/electron/electron/releases/download/v12.0.7/ffmpeg-v12.0.7-darwin-arm64.zip . What's the purpose of this binary ?

     


  


  


  Any help would be appreciated.
