 1 | Use these scripts to download a bunch of YouTube videos.
 2 | 
 3 | 1. Download and install youtube-dl on your system:
 4 | 
 5 |     http://rg3.github.io/youtube-dl/
 6 | 
 7 | 2. Execute the "enqueue" script:
 8 | 
 9 |     ./enqueue.sh
10 | 
11 | 3. Paste URLs of YouTube videos at the command line.
12 | 
13 | 4. Watch the downloads go!
14 | 


--------------------------------------------------------------------------------
/NOTES:
--------------------------------------------------------------------------------
 1 | * Tested on Ubuntu 12.
 2 | 
 3 | * The downloader will start automatically as soon as you start
 4 |   enqueueing URLs.
 5 | 
 6 | * If downloads are disrupted for any reason, the queue can be started
 7 |   again (by running "enqueue.sh") and should recover to where it
 8 |   left off.
 9 | 
10 | * To change the options passed to youtube-dl, change the YOUTUBE_DL_OPTIONS
11 |   variable in downloader.sh.
