SVOPC · 16 January 2008 by Alex Beregszaszi
Per Wikipedia:
SVOPC (ang. Sinusoidal Voice Over Packet Coder) is a lossy speech compression codec designed specifically towards communication channels suffering from packet loss.
SVOPC is the latest speech codec used in Skype conference chats. Not much is known about it yet, but my personal taste is that iLBC sounded much better.
Opensource MPL · 15 October 2007 by Alex Beregszaszi
MPL aka Meridian Lossless Packing is an audio compression technique mostly used on DVD-Audio discs. For a long time only proprietary decoders existed until finally Ian Caulfield succeeded in understanding the format and submitted an initial implementation to FFmpeg.
Nellymoser Asao · 3 October 2007 by Alex Beregszaszi
The Nellymoser Asao codec is a proprietary single-channel (mono) format optimized for low-bitrate transmission of audio. – according to the Multimedia Wiki
This format was once widely used in Macromedia (now Adobe) Flash files and currently is the only sane codec for encoding from microphone at the user.
For a long time there has been no support for this outside the Flash Player, thus people went as far as offering bounty for writing a decoder.
Now a few weeks ago someone took the nelly2pcm code and ported it into FFmpeg. Still not committed in its current state as Benjamin Larsson discovered it can be implemented with reusing much more code from the framework.
Also the codec is used with some changes under different names (information based on an old email), we have to get a view of those samples.
It will be available once the required changes are done. We can thank already the maintainers for their picky attitude about quality.
Les Trophées du Libre · 3 October 2007 by Alex Beregszaszi
Is an international free software contest held in France.
I had been offered a place in the multimedia category of the Jury. The nomination phase is now over, over 25 projects have been submitted to my category.
The multimedia jury includes Sam Hocevar of VideoLAN (and now Debian) fame, also he created the WTFPL license ; Damien Sandras, author of GnomeMeeting/Ekiga; Øyvind Kolås from GIMP; Louis Desjardins contributed to Scribus, and Olivier Saraja to Blender.
Thanks to this page, I am aware that there is a Libre Graphics Meeting, last year organized by Louis.
Google Video uses FFmpeg · 24 March 2007 by Alex Beregszaszi
Google Video Player is a Windows player application, which downloads and stores the videos as MPEG4+MP3 in AVI.
When looking into the “HBO Special: Hacking Democracy” I noticed that it was encoded with Lavc51.7.0.
However, for some unknown reason the creator inserts some fake RIFF chunks, thus it is not yet fully playable with open source tools.
Really open AVS · 9 June 2006 by Alex Beregszaszi
Remember the chinese doing their own multimedia standard? And it’s name AVS (Advanced Video coding Standard, how much creative)?
It aims to compete with H.264 and MPEG4. Wondering how they can do it without harming tons of useless patents?
Now they started writing an implementation under a free software license. It’s called OpenAVS. Good.
Windows Media Photo · 28 May 2006 by Alex Beregszaszi
Windows Media for president.
As I am pessimist in regard with Microsoft standards, this Media Photo stuff smells again like the usual way: trying to spread the usage of some own remake of the available tools. Once its used widely enough, try increasing the fees for it. At least after the competition is not possible.
Why do they like this borg-ideology?
