Open Source Codec Software

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: https://www.ccextractor.org Files in sourceforge are left for archival purposes, but new releases will be available from ccextractor.org.

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 a versatile, modern image format suitable for both simple photos and advanced imagery needing high fidelity. The specification ensures interoperability across encoders and decoders, providing guidelines so that images created by any compliant AVIF encoder can be reliably decoded by compliant decoders. As adoption grows, AV1 AVIF plays a crucial role in promoting a royalty-free, open, high-efficiency image standard that competes with older formats such as JPEG and newer proprietary ones.

** Now on Github; https://github.com/aizvorski/h264bitstream ** libh264bitstream provides a complete set of functions to read and write video bitstreams conforming to the ITU-T H.264 | ISO/IEC 14496-10 AVC video standard.

libsmacker is a cross-platform C library which can be used for decoding Smacker Video files produced by RAD Game Tools. Smacker Video was the king of video middleware in the 1990s, and its 256-color compressed video format was used in over 2600 software titles. Please visit the Project Web site for detailed information.

PyramidWorkshop is an image-compression System based upon the scientific work of John Robinson (inventor of BTPC) about image-compression with adaptive linear predictors and is in average more efficient than PNG/JPEG2000.

Defa Protector is A Simple PHP and Wordpress Plugin To Protect and Prevent Video Save As From Browser and Some Video Grabber. There is 100% Guaranteed Protection and There might be some tradeoff but If you care about Digital Rights Management of Your Video and Music Content. This Project is for you. Defa Protector 6.7.1 Revamp Code For Better Performance To The Bone. We almost rewritten this project from scratch.

That is an video encoder that implements h264 encoding. Main goal is to provide lite Java h264 implementation for Applets and Client development.

A Java port of XviD.

An implementation of the VP8 image/video codec in pure Java.

Libavinterface is a C++ wrapper library for the C video library FFMPEG and the C graphics library SDL. It is designed to be class-based, predominantly for scenarios where non-class data is impossible (eg. the VST SDK). It is designed for mingw/msys.

OpenAVS is the open source implementaion of AVS (Advanced Coding of Audio and Video ). AVS is competing with MPEG-4 and H.264 to replace the current worldwide compression standard, MPEG-2.

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

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.

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.

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.
