boilerpipe provides algorithms to detect and remove the surplus "clutter" (boilerplate, templates) around the main textual content of a web page.

For maximum compatibility, here’s what your video workflow will look like:

1. Make one version that uses Theora video and Vorbis audio in an Ogg container.
2. Make another version that uses WebM (VP8 + Vorbis).
3. Make another version that uses H.264 baseline video and AAC “low complexity” audio in an MP4 container.
4. Link to all three video files from a single <video> element, and fall back to a Flash-based video player.

a very simple web-based API to detect and extract the main content from a web page, removing all of the clutter, such as headers, footers, advertising and so on. I guess it’s somewhat similar to Readability or Instapaper, but more suitable to building into your own applications. Watch this space.
