YouTube Playlist Downloader Frontend Interface For get-flash-videos

Hi. The following Tcl/Tk script is just a frontend interface for the application get_flash_videos.

get_flash_videos downloads online videos from websites like YouTube and save them as a normal file where you can watch the video directly from your computer without the need to use the Internet at all.

The problem with get_flash_videos is that it only downloads a single video and it does not download a complete playlist. This means it does not download each video belonging to this playlist. Therefore I made this interface script.

I made this script to run on Debian GNU/Linux 7.0 . It should work on other Linux systems.

You have to understand that this ONLY downloads YouTube playlists. Nothing else.

To run this script :

Install get_flash_videos from Debian repository: apt-get install get-flash-videos
Install ActiveTcl and update teacup using the command teacup update
Copy the script to a text editor as a new empty file and save it as youtube.tcl
Set it executable : chmod 775 youtube.tcl
Run the script file youtube.tcl from terminal from its save location as ./youtube.tcl
All you have to do now is just copy the playlist URL from your web browser, paste it in the frontend interface, and press the button and wait until the whole list is downloaded.

The script is below this line.

#!/usr/bin/wish

if { [ catch { exec which get_flash_videos } ] !=0 } {
  tk_messageBox -icon error -title "Missing Application" -detail "Please install the package get-flash-videos because it's missing. It's the download tool.\nIn debian systems as user 'root' enter on your terminal:\n\n apt-get install get-flash-videos"
  exit
