My university, the Hasso-Plattner-Institute in Potsdam/Germany, has an extensive online repository of recorded lecture videos at http://tele-task.de/. Sadly the website is not an engineering highlight. Thus most people just want to fetch the video assets and consume them in other ways. Boom, this script should help you.
It's a ruby script. I used ruby 2.0 for development, but it should also run with ruby 1.9.x. Packet management is done via bundler.
gem install bundler bundle install
To download videos you need the
wget tool. It usually ships with your OS, otherwise you can use your favorite packet management tool to download it, e.g. via
brew install wget or
apt-get install wget.
As input you always need to provide a feed url. You can obtain the url from Teletask on the lecture page on the right top corner. It's not the rss-logo (
Lecture-Feed of Series) but the iTunes-y cube next to it (
Feed of Series).
Feed to XSPF
ruby teletask-cli.rb --xspf http://tele-task.de/feeds/series/946/
ruby teletask-cli.rb -x http://tele-task.de/feeds/series/946/
XSPF is a playlist format that can be read by many popular media players, e.g. VLC. It also accepts urls, thus you can stream right away.
The cli option
--xspf accepts a url to a series-feed on Teletask. The generated
output.xspf links directly to the .mp4 assets on the Teletask servers. You should be able to drag-and-drop the xspf playlist into your favorite player and stream the videos directly.
ruby teletask-cli.rb --download http://tele-task.de/feeds/series/946/
ruby teletask-cli.rb -d http://tele-task.de/feeds/series/946/
You can download all .mp4 video assets by using the
-x cli option with the feed url. The files will be saved with the original file names in the folder you executed the script in. Downloading happens via
Fork away. I'm happy to accept pull requests, there is a lot of stuff to be added.
