M3U8 download app for MacOS

Usually I work via Terminal but sometimes I don’t remember all parameters of a binary and search for such takes time. Same issue I had for ffmpeg downloads of M3U8 files. So I created a small apple script (for some dialogs) and saved this as very simple application. I use it regulary now and after all I thought to share here.


A little preparation is needed, if you have ffmpeg binary allready installed you can skip to next section. So download the ffmpeg binary as an archive from https://www.ffmpeg.org/, unzip and follow next commands. In my example the binary was unzipped into folder “Downloads”.

# move ffmpeg binary
$ mv ~/Downloads/ffmpeg /usr/local/bin/ffmpeg

# set permissions
$ chmod +x /usr/local/bin/ffmpeg

# check version (optional)
$ ffmpeg -version

Apple Script

Open the Scripteditor and copy/paste the following script there.


global theURL
global theOutputFolder
global theOutputFileName

on SetURL()
  set theTitle to "Video URL"

    set theURLDialog to display dialog "What's the file URL?" default answer "" with title theTitle buttons {"Continue"}
    set theURL to text returned of theURLDialog
  on error
  end try

  if theURL as string is equal to "" then
  end if
end SetURL

on SetOutputFolder()
    set theOutputFolder to choose folder with prompt "In what folder you will save the file?"
  on error
  end try
end SetOutputFolder

on SetOutputFileName()
  set theTitle to "File Name"

    set theOutputFileNameDialog to display dialog "What's your target file name?" default answer "" with title theTitle buttons {"Continue"}
    set theOutputFileName to text returned of theOutputFileNameDialog
  on error
  end try

  if theOutputFileName as string is equal to "" then
  end if
end SetOutputFileName

on RunTerminal()
  set theTargetPath to POSIX path of theOutputFolder & theOutputFileName
  set theCommand to "ffmpeg -i " & theURL & " -c copy -bsf:a aac_adtstoasc " & theTargetPath

  tell application "Terminal"
    do script with command theCommand in window 1
  end tell
end RunTerminal

on quit
  display dialog "Thanks for trying this!" buttons {"Continue"}
  continue quit
end quit

on run

end run


Now you can “save” or “export” the script as “app”.
