Summary

Ubuntu Media Center should provide a huge codec support in order to be able to play most (all!) of the existing media formats.

Implementation

Ubuntu Feisty will come with a package called ubuntu-restricted-extras which installs main non-free codecs (multiverse repository). This package should be included by default in Ubuntu Media Center.

Codecs

The following table shows the audio and video codecs that are expected to be supported by the UMC.

It is based upon the assumption that the UMC will rely upon the Elisa software, so will be using the gstreamer framework.

1 : [http://gstreamer.freedesktop.org/modules/gst-monkeysaudio.html Gstreamer MonkeyAudio plugin] has never been ported to 0.10

2 : RealAudio codecs are a mess with at least 9 variants : (dnet, atrc, raac and racp are the only 'standard' ones)
