lyra is a neural audio codec designed to deliver intelligible, natural-sounding speech at extremely low bitrates, making real-time communication viable on constrained networks. It replaces hand-engineered codecs with learned models that capture speech characteristics more efficiently and reconstruct waveforms with a neural vocoder. The system targets mobile-class hardware, balancing latency and quality so it can run in real-time on phones. Its architecture is resilient to packet loss and jitter through framing strategies and error concealment, helping conversations remain understandable under adverse conditions. The codebase includes encoder and decoder components, along with tools for data preparation and evaluation. By pushing bitrates down to just a few kilobits per second while retaining quality, lyra expands access to voice calls where bandwidth is scarce.

This is a continuation of Ogg.class.php by Nicolas Ricquemaque, which in turn was a split from File_Ogg by David Grant (don't you love Free Software?). Initially this project will just fix bugs and make minor adjustments to Ogg.class.php code, no backward incompatible changes will be made without an announcement. The version numbers will continue from the 1.3g, the latest released version of the ancestor project. Note: This project will __not__ help you to convert your media files into Ogg or to mux several Ogg streams together. It __will__ help you to get correct information about an already converted file.

What is PlusV? With traditional MP3, a typical Near CD Quality audio file has been encoded with a data rate of 128 kbits/s. While this is ok for people with big hard disks and fast Internet connections, this data speed has clearly been a bottleneck for people using modems or storing their music into 32 or 64 MB portable player FLASH cards. PlusV is a brand new audio compression enhancement technology that allows audio files to be compressed in as little as 64 or even 48 kbits/s. PlusV is not a compression scheme of its own, it is an extension that can be applied to existing audio formats. When combined with the MP3 technology, MP3+V files are fully compatible with existing MP3 files and decoders. To get full audio quality out of PlusV files, you just need a PlusV capable decoder, like a PlusV capable WinAmp plugin.

Implementation of a RLE encoder/decoder library tailored for DICOM image.

Rippy is a script designed to make ripping DVDs easier. It uses mplayer and mencoder to transcode a video to another format. Features: automatic bitrate calculation based on desired target size; automatic crop detection; mp3 audio with resampling;

Tools and library to extract, analize and inject metadata in FLV(flash 8) video files.

A pure java port of the avilib that was part of Blender 2.37. Can read and write MJPEG-encoded AVI-contained video files only.

jipCam provides a JMF-based datasource implementation for IP-based video cameras. This allows Internet Procotol based cameras like the Axis 2100 or 2120 to be used directly in a Java Media Framework enabled video application.

libflv is library to create FLV video streams for use with Flash/SWF movies.

Forked version of abandoned project MPEG4IP ( http://mpeg4ip.sf.net ) The MPEG4IP project provides an MPEG and IETF standards-based system for encoding, streaming, and playing audio and video.

otrutility is a frontend for the command line decoder tool provided by http://www.onlinetvrecorder.com. It supports drag'n drop and the decoding of multiple files per run.

peerswap, bit-torrent browser streaming plug-in

Adobe(R) Flash(R) Video format (FLV) to MPEG4 Transcoder.

We will create a complete MPEG4 part 14/Quicktime parser in Java, add a full working example in J2ME and then port the whole thing to C#.

BGZip is a compressor that uses BWT and others techniques to compress archives, sounds and videos with in high compression rates.

MPlayerX is armed by FFmpeg and MPlayer, which means it could handle almost any media format in the world for you and no extra plug-ins or codec packages are required. Just drop anything to it, MPlayerX will give you a clear and smooth playback.
