RAW yuv player project is moved to GITHUB. Visit: https://github.com/Tee0125/yuvplayer Old description: Lightweight player for raw YUV/UYVY files.

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.

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.

Video processing source code for algorithms and tools used in software media pipelines. The currently available source code is written in C++ with their associated libraries and DirectShow Filters. Filters include an H.264 encoder, H.264 decoder, H.264 source filter, RTSP sink and source filters, YUV source, RGB to YUV color conversion, croppers, scalers, video mixing/picture in picture filters, rotate filter, virtual mic, and many more. Code is released under BSD license with exception of H.264 codec related classes which are released under LGPL.

This video transcoder converts various video formats into High quality H.264 or mp4 format which is specially optimized for YouTube channel. This application will help you to achieve the recommended upload encoding settings by YouTube. Thus, making your video look flawless on your YouTube channel. Additionally its audio section helps you to extract audio files out of various audio and video formats. It supports exporting audio files into various audio formats namely, FLAC, MP3, WAV, OGG, WV and AAC formats. How to run application ? 1. Extract the zip file and open the folder 2. Run "YouTubeVideoTranscoder"

Optimized H.264 baseline codec for PC and TI DSP DM6437.SFIPExe is TI DSP DM6437 based video/audio/command/sensor interface for IP address activities controlling. Information available at: http://www.smallfishdev.com. "SFIPExe" Video availabe in YouTub

HAX264 is a Microsoft Windows DirectShow Video Transform Filter for decoding H264(AVC) video.

MPlayer with all essential codes, encoders, decoders & filters. For LINUX users: just extract the source & run the 'install.sh' file from Terminal. For Windows users: Not Tested yet, but hope to work on MINGW32 in WinXP. Thanks from Chinmoy & Srijon

DEFINITELY LOSSLESS provides a solution to reliably transmit video data from one location to another. Context: Up until now, standardisation organisation such as the Video Quality Experts Group (VQEG) or the International Telecommunications Union (ITU) have used only uncompressed video formats. The H.264 standard and its implementation in FFMPEG allows for lossless transmission of video data at a smaller file size. Purpose: DEFINITELY LOSSLESS simplifies the manipulation of YUV422 video data embedded in AVI files with UYVY422 Four-CC code. It also checks for truncation and correct reconstruction of the uncompressed video at the receiving side. Disclaimer: Please note, that this project is for experts in video processing. If you are not familiar with the above mentioned video formats, this project is probably of no use for you.

EvilEncoding is a software for parallel video encoding. You can encode one movie parallel on multiple computers. So you would have an enormous performance boost. As encoding engine mencoder will be fully featured used.

This project aims to establish a framework for Fully Configurable Video Coding and will demonstrate adaptation, communication and instantiation of decoding structures in a prototype fully-configurable video codec.

A video compressor using the GPU computational power to improve the speed up.

H.264 Stream Editor is a re-coding application developed by TATA ELXSI LIMITED, that allows the user to edit the configuration parameters of the H.264 Bit stream files, therby obtaining a custom configured video file.

Intel Integrated Performace Primitives audio/video codecs plug-in for the OPAL/OpenH323 library including G.728, G.729, G.723.1, G.722.2 GSM-FR, GSM-AMR, H.261, H.263, H.264 and MPEG4 part 2.

This codec was developed for the purpose of bachelor's thesis on Faculty of Information Technology, Brno University of Technology, Czech Republic. Project is under LGPL licence. You can use this codec e.g. for screen recording via CamStudio. Records can be directly imported in Vegas Pro/Movie Studio.

Kumaji is an advanced subtitle rendering library aiming for complete cross-platform support, complete and compliant support for all common subtitle formats and, of course, speed. The source code is also intended to be easy to understand and hack at.

LibVideoCoding is a C++ library supporting the development of video codecs. The library comprises support for fast FDCT, IDCT, motion compensation, and reading and writing MPEG-2/4 conform video and system bit-streams.

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.

The aim of this project is to explore MediaFoundation API. It provides some ways on how to use it. This project is just experimental, and you can see it as an extension to the MediaFoundation samples. You will find : - audio/video player (win32) - custom media session - sequencer source - audio/video capture - screen capture - kinect V1 capture - wave audio mixer - http streaming (winsock) - jpeg encoding (Gdiplus) - dxva2 technologie - cuda decoding - directX9 renderer and shader - COM technologie - different kind of mediafoundation Source, Sink and Transform (mpeg2, flv, a52, vp6...) - mp3 to wave transcoder See readme in files section for more.
