AV1 Image File Format Specification - ISO-BMFF/HEIF derivative
AV1 AVIF is the official specification and reference design for the AV1 Image File Format (AVIF), defining how AV1-encoded bitstreams are packaged into the HEIF container format (based on ISOBMFF) to produce AVIF files. The project outlines the syntax and semantics required for AVIF compliance, including support for multiple image profiles, color depths, chroma subsampling modes, HDR/WCG, alpha channels, animation/image sequences, and various color-space/bit-depth combinations — making AVIF...
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...
An Open Source alternative to SBR (Spectral band replication)
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.

A fast closed captions extractor for MPEG and H264 files. Supports DVD, HDTV transport streams, Replay TV. Use this to create .srt (subtitles) files for your TV captures, have transcripts so you can edit subtitles, etc.
This project has moved to its own domain:

Files in sourceforge are left for archival purposes, but new releases will be available from ccextractor.org.
A free decoder that utilizes the Intel QuickSync technology
Abstracts the hassle of HW accelerated decoding in Intel's 2nd generation Core i3/i5/i7/Pentium/Celeron (SandyBridge) or newer Intel CPU/GPU using the Intel QuickSync technology.
Started as an internal decoder within FFDShow. Can be easily ported to other DirectShow decoders.
The Intel QuickSync decoder is now used within FFDShow, LAV video decoder and PotPlayer.
Open SVC Decoder aims to provide a real-time coding framework for Scalable Video Coding extension of H.264/AVC.This project is AVC/SVC library decoding tools created at the IETR/INSA of Rennes. Please have a look at the project web site for more details
FRONTEND for mencoder for Windows and Linux. Convert rmvb,avi,mp4,wmv, ogv, mkv, mov, mpg, vob,ogv, ogg, ogm etc To avi (divx5), xvid, dvd iso, h264 in a simple way. Required java runtime 6 and over. (On Linux is required mencoder, dvdauthor and mkisofs)
P264Decoder is a free h.264 decoder. It support baseline profile and x264 base bitstream now. The initial p264decoder version is based on the uncompleted x264 decoder. website: http://p264decoder.zj.com
This project aims to development a universal media codecs for video/audio/image processing.
It use same interfaces for all codecs. And it target system is embedded system. The codecs will be include: MPEG2, MPEG4, H264, AAC, VC-1, AVS.
