Theora 1.1

Fedora 12 ships with an improved version of libtheora. This new version codenamed Thusnelda gives users better video quality while keeping the size of a video the same. --Needs More--

Volume Control

Following in the foot steps of Fedora 11 volume control now includes profile support, better input switching, and fade control. --Needs More--

Thusnelda

In support of Free Culture, the open web and to reduce the hold of proprietary and patent encumbered codecs, Red Hat has been sponsoring improvements on the open Ogg Theora video codec implementation codenamed Thusnelda via Christopher Montgomery (xiphmont), who created the format and work has resulted in drastic improvements to the codec. This release features this next generation codec. All applications using libtheora library including all the Gstreamer applications will automatically and transparently be taking advantage of the improvements.

PulseAudio Enhancements

Fedora developers have been made several improvements to the PulseAudio system. More details here. These include the following:

• A New Mixer Logic
• UPnP MediaServer Support
• Hotplug Support Improved
• Surround Sound Support for Event Sounds

Fedora Studio

Motivation

We have a wide range of applications and libraries dedicated to media production. See, for instance, the AudioCreation page for a list of our audio creation related applications.

Currently, the media production applications go into the Multimedia group (Sound&Video group in GNOME) in the desktop menu, mixing up with audio/video players (we also have a wide range of such applications), and make this group rather cluttered.

Outline

The key is to make the applications easily accessible. Too many subcategories and the inexperienced user will get lost. In the table below, we propose a solution to this problem by grouping applications that show similar features. The (sub)categories are bulleted and are in bold. The numbered entries indicate what type of applications will fall into the corresponding (sub)category. The green entries associated with each group indicate what type of .desktop file categories each group will host. If any application goes into any of the submenus, it will not be displayed in top menu.

Benefit to Fedora

The number of available desktop applications of both player and production types is increasing every day. Listing these programs under different (sub)categories in the desktop menu, will make the Multimedia group (Sound&Video group in Gnome) look sane and make both type of applications more accessible.

Scope

1. Either the existing /etc/xdg/menus/applications.menu file need to be edited, or a new .menu file will be added into /etc/xdg/menus/applications-merged/. For a test drive, grab the RPM from http://oget.fedorapeople.org/multimedia-menus/
2. The .desktop file for each Multimedia GUI application needs to be revisited and the proper "Category" key(s) will be assigned.
3. 11 new icons will be requested from Fedora art team for new submenus. Temporary icons will be used until they are made.
4. Localization team will be contacted for translations of new submenu names and comments.

Note that certain applications will fall in more than one category. There is nothing wrong with that. Listing the application in the correct category(ies) will make it more accessible.

Release Notes

An optional multimedia-menus package is provided for the users who want to have their audio & video applications classified in their desktop menu.
