File format

The video file format is .ogg. Thought ogg was a music format? Well, you're right, sort of. Ogg is the name of Xiph.org's "container format" for audio, video, and metadata. When it holds vorbis-encoded audio, the file is called "ogg vorbis" - vorbis is the name of an audio compression code. The actual video codec used is called theora. This ogg file has theora-encoded video and vorbis-encoded audio.

This means VLC, for one, can play this file, but its performance lags a little. Other apps to try:

• Realplayer and its fully open-source cousin Helixplayer (Real and Helix now have the same sort of relationship that Netscape and Mozilla once had - Realplayer is about 90% open source these days). Xine (this is what I use).
• Anything based on the libxine or gstreamer libraries (e.g. Gnome's Totem, KDE's Kaboodle or Xfce's Xfmedia).
• You can also get Directshow plugins for Windows Media Player and other Directshow-based apps.
• Basically, any reasonably up-to-date GNU/Linux system should play this out of the box, and Windows and Mac should play it with only a little effort. In Gentoo you have to set the useflag USE="theora" to be able to watch the video.

The file formats and codecs described here are open source/open standards, thus they are given preferential treatment by this project on philosophical grounds.
