JauntyCodecInstall

Revision 5 as of 2008-11-26 13:06:03

Clear message

Summary

Debian has a new mechanism for doing codec installation. Packagekit is also capable of doing codec installs now. We should evalulate if he should keep our version (based on gnome-app-install) or switch to one of the new systems.

Release Note

TBD

Rationale

The codec install information is now part of the Package file. This is a feature that we inherited from debian and that we should use.

Design

The codec install information is now part of the Packages file, it looks like:

Description: GStreamer plugins from the "good" set
 GStreamer is a streaming media framework, based on graphs of filters
 which operate on media data.  Applications using this library can do
 anything from real-time sound processing to playing videos, and just
 about anything else media-related.  Its plugin-based architecture means
 that new data types or processing capabilities can be added simply by
 installing new plug-ins.
 .
 This package contains the GStreamer plugins from the "good" set, a set
 of good-quality plug-ins under the LGPL license.

Together with this debian has a new codec install application """gnome-codec-install""" that uses this information. We should evaluate if that codec installer can supersede gnome-app-install. We also should check the packagekit codec installer and decide which one should be the default.

gnome-app-install

  • what we use now
  • - uses static data from /usr/share/app-install
  • - needs lots of clicks to install something
  • + uses fast dbm hash database to give instant feedback if codec is availabe
  • + knows about codecs even if they are in a not enabled component (e.g. multiverse codecs on a system without multiverse enabled)

gnome-codec-install

  • what debian uses now
  • - search relatively slow (goes over the full Packages files)
  • - relatively new (had trouble with it on my debian/sid system)
  • + does not need app-install-data package to function (easier updates)

packagekit codec install

Implementation

TB

UI Changes

Should cover changes required to the UI, or specific UI that is required to implement this

Test/Demo Plan

Download a mp3 file from the net and double click on it to see the installer in action.

BoF agenda and discussion

Note that the BBC patch to totem relies on internals of the current implementation, and would need to be updated. -- ColinWatson
