HEVC Video Extensions from Device Manufacturer is the official application for playing the HEVC (H.265) codec on Windows 10 and Windows 11. Microsoft offers two identical applications for playing this codec natively by hardware. The only difference between them is that one costs money and the other is free. The free one is included on new devices sold by big brands, like laptops that come with Windows pre-installed. These manufacturers don't have to pay to include the codec. Luckily, you can download the codec for free and install it on your own computer. That's what this file offers. After installing it, you can play videos and movies recorded with the HEVC (H.265) codec. Most 4K movies are recorded in this format, so with this application, you'll be able to play them using the native Windows application called Movies and TV.

Dolphin DVR Player is one very easy-to-use powerful but totally free player for DVR videos, NVR Videos, HVR videos and CCTV videos. Dolphin DVR Player is one professional H.264/H.265 video player and can play all H.264/H.265 video files smoothly. Dolphin DVR Player is also one NVR, HVR and CCTV video player, only if the video coding is H.264 or H265, the Dolphin DVR Player can detect the video coding type automatically.

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.

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.

** 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.

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.

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

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.

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.

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.

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.
