This could be a good chance to solve the DVD movie player issue:

QUOTE

DVD player is sold separately because MPEG patents require a fee for delivered decoders. Free or open source software are no exception.

Let's read the official press release:

QUOTE

Mozilla has awarded a grant of $100,000 to the Wikimedia Foundation to help coordinate improvements to the development of Ogg Theora and related open video technologies. Mozilla and Wikimedia share a strong commitment to open standards. Version 3.1 of the Mozilla Firefox web browser will include built-in support to play audio and video in the open source Ogg Vorbis and Ogg Theora formats. All audio and video in Wikipedia is stored in these formats. Mike Shaver, VP of Engineering at Mozilla has blogged about this great news, as has Chris Blizzard, Director of Evangelism for Mozilla.

Open standards for audio and video are important because they can be used by anyone for any purpose without royalties, and can be inspected and improved by an open community. Today, video and audio on the web are dominated by proprietary technologies, most frequently patent-encumbered codecs wrapped into closed-source player widgets. Wikimedia and Mozilla want to help to build a web where video and audio are first class citizens: easy to use and manipulate by anyone, without compulsory royalty schemes or other barriers to participation.

The $100,000 grant will be used to support the work of long-time contributors to the Ogg Theora/Vorbis codebase and related tools, such as libraries for network seeking. The improvements will be made over a 6 month period.

Erik M�ller,
Deputy Director, Wikimedia Foundation

And as I previously claimed @ Kolibri forum:

QUOTE

If you're scared about MPEG-LA, then support royality-free/open source codecs:

Vorbis for lossy audio (THE mp3 competitor - check out the Ogg Vorbis acceleration project that introduced asm-optimizations into the codec);
FLAC for lossless audio;
Theora for streaming video (the "comparable" XviD competitor, included in the next FireFox version);
Dirac for HD video (the h264 competitor);
Huffyuv for lossless video;

Note that assembly implementations/optimizations of those codecs would benefit the whole community too.

OGG Vorbis, particularry, has already some "ASM optimization" project:

Ogg Vorbis acceleration project

Unfortunally the last release is quite outdated (2006 November 10th)...

Hope that helps or at least inspires !

We will always have open-source everything, but there are also some royalty-greedy something and if they are popular (like displaying a DVD-video), you need to support them also, because otherwise you won't have a full 100% support for massively used codecs etc. This does become very valuable when open-source codecs start to get even more popular.

Lets all raise our hands, who will contribute. I have previously stated on many projects that I have time constraints: work, family, etc. and I won't be able to commit 100%. What I can do is improve some small snippets from time-to-time. As for MenuetOS I did the line and circle routines etc. some small things, but not huge tasks. I'm in! (Raised hand)

Theora: Thusnelda project update 20090820

QUOTE

Since the last update from around the time of 1.1alpha2, Thusnelda has moved to the SVN trunk where work has concentrated on final features, cleanup and testing for the Theora 1.1 (Thusnelda) final. We're very close to the complete 1.1 and have already released two 1.1 release candidates. We'd optimistically scheduled final 1.1 release for last week, however we're taken some additional time to do more testing/tuning of the two-pass rate control.

New features

Two-pass encoding
Frame Dropping
Variable frame rate support
Adaptive Quantization
4:2:2 and 4:4:4 support
New Telemetry

Other Improvements

Improved one-pass bitrate management
Early SKIP analysis
New quantization matricies
Fully pipelined encode
Dynamic token optimization
Speed optimization
Encoder/decoder shared code merge

Side Work

yuv4ogg
Adaptive quantization heuristics
