Packing It In: The Evolution of Online Video and Audio Tech, Part 1
,----[ Quote ]
| As Internet users increasingly discover the wonders of downloading audio and
| video files, they probably don't think much about how those files are
| prepared for transmission. Compression formats can be a contentious issue --
| vendors sometimes use them to lock users into their format -- and the open
| source world is working to even the field.
|
| [...]
|
| A host of incremental improvements and new features comprise what today is
| considered "state of the art" in audio compression codecs and technology,
| according to Shy Keidar and Meni Berman, members of the team behind Musepack,
| an open source audio codec and supporting technology that according to the
| two sources is the second-most widely used non-proprietary, general purpose
| and open source "lossy" audio format after Ogg Vorbis.

Summer of Code: Ogg Theora Port
,----[ Quote ]
| Porting open, patent free codecs to our devices has always been of great
| interest to neuros and many of our users. As some of you Neuros old timers
| may recall, we were the first to port the Ogg Vorbis audio codec to a
| portable HDD audio player. Now it's time, hopefully, to do the same with the
| Ogg Theora video codec.

Sun Tackles Video Codec
,----[ Quote ]
| Looking to boost the Web, Sun is working on a royalty-free and open video
| codec and media system, company officials said Thursday afternoon.
|
| [...]
|
| Currently, proprietary solutions are relied on, such as Adobe's Flash or
| royalty-bearing specifications like H.264, Glidden said.
|
| OMS is a recent project. Asked about the availability of OMS technologies,
| Glidden said, "Stay tuned. I have no announcements on any commercial
| implementations or time frame."

Worlds first high performance Dirac video codec implementation available
,----[ Quote ]
| Thanks to collaboration with the Xiph.org foundation there is an official
| mapping for putting Dirac video into the Ogg container format underway, and
| the Schrödinger project also hosts a proposal for mapping Dirac into the
| popular MPEG-TS container format, which is currently being considered for
| certification by the MPEG working group. We expect to see and provide
| mappings for a lot more container formats in due course.
