libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.

LAME is an educational tool to be used for learning about MP3 encoding. The goal of the LAME project is to improve the psycho acoustics, quality and speed of MP3 encoding. Note: we provide source code only!

ffdshow is an advanced DirectShow filter and Video for Windows codec (VFW) codec that supports many audio and video formats. For example: H.264, MPEG-4, MPEG-2, H.263, VP3, VP6, Theora, MJPEG, SVQ3, MP3, AC3, DTS, E-AC3, AAC, and Vorbis.

Do you need quick capture and encoding capabilities for video on your desktop? VirtualDub is a free, Open Source solution specifically designed for that purpose. VirtualDub might lack the editing power of a general-purpose editor such as Adobe Premiere, but is streamlined for fast linear operations over video in return. It has batch-processing capabilities for processing large numbers of files and can be extended with third-party video filters.

Mikmod is a module player and library supporting many formats, including mod, s3m, it, and xm. Originally a player for MS-DOS, MikMod has been ported to other platforms, such as Unix, Macintosh, BeOS, and Java(!!)

MMC is a commander-style media player for Windows, with native, hw accelerated video playing and translucent gui. Mpxplay is a console audio player for DOS and Win32 operating systems. x264vfw, x265vfw and xAV1vfw are video for windows encoder and decoder codecs, useful with VirtualDub.

libmng -THE reference library for reading, displaying, writing and examining Multiple-Image Network Graphics. MNG is the animation extension to the popular PNG image-format.

rav1e is an open-source implementation of an encoder for the AV1 video codec, developed in Rust (with some assembly) by the community around Xiph Foundation. Its design philosophy is to start from a correct, minimal, and fast AV1 encoder — sacrificing some encoding speed/efficiency of reference encoders in exchange for simplicity, stability, and compilability across platforms — and then gradually improve. This makes rav1e particularly attractive for scenarios where you need AV1 encoding but care about build-time, portability, and maintenance overhead, or where the full-featured reference encoder might be prohibitively slow. Despite aiming for simplicity, rav1e supports a wide range of AV1 features: different bit depths, chroma subsampling formats, prediction and transform modes, and block partitioning options, which means it can produce reasonably efficient compressed video.

FLAC is a free lossless compressed audio format which supports streaming and archival. The FLAC project maintains the format and provides a reference encoder/decoder and input plugins for several popular audio players.

Use Cemu's built-in graphic packs downloader (a feature added in Cemu 1.15.1) to automatically retrieve the newest graphic packs from our repository. Remove all of your graphic packs first, then move all of the folders from a downloaded .zip below to the graphicPacks folder from your Cemu folder. Choose one of the 3 downloads from above. Each download has a range of versions it supports, pick the one that’s supported by your downloaded Cemu version. Some graphic packs might not be available for Cemu 1.14.0 and newer while previous versions did have graphic packs. This is due to the full reimplementation of the texture system in Cemu 1.14.0. This also changed a lot of the aspects with textures and made all previous graphic packs that changed textures outdated.

Mjpeg tools is a suite of programs which support video capture, editing, playback, and compression to MPEG of MJPEG video. Edit, play and compression software is hardware independent. Capture supports MJPEG hardware (Buz,DC10+ etc). and V4l2 devices.

LSP (Linux Studio Plugins) is a collection of open-source plugins currently compatible with LADSPA, LV2 and LinuxVST formats. Standalone plugins for JACK are provided since version 1.0.8. Experimental support of ARMv7 added since version 1.1.4 Experimental support of AArch64 added since version 1.1.9 Decomposition of modules and new UI introduced in 1.2.0 Added CLAP support in 1.2.5 Added VST3 support in 1.2.15 The basic idea is to fill the lack of good and useful plugins under the GNU/Linux platform. After some contributions to other open source projects the decision was made to implement separate and independent plugin distribution.

A crossplatform music editor for creating Commodore 64 music. Uses reSID library by Dag Lem and supports alternatively HardSID & CatWeasel devices.

xine is a free multimedia player. It plays back CDs, DVDs, BluRays and VCDs. It also decodes multimedia files like AVI, MOV, WMV, and MP3 from local disk drives, and displays multimedia streamed over the Internet.

An application that does scaling/deinterlacing/inverse telecine using a high powered PC and certain TV capture cards. Essentially, this software converts a PC into a good-quality line doubler/scaler/upconverter machine!

Legacy repository for Avisynth. Visit http://www.avisynth.nl/ or https://github.com/AviSynth for updated information. Avisynth is a scripting language and a collection of filters for simple (and not so simple!) non-linear video editing tasks. It frameserves video to applications.

The Quasar DV Codec (libdv) is a software decoder for DV format video, as defined by the IEC 61834 and SMPTE 314M standards. DV is the encoding format used by consumer-grade digital camcorders.

PCSX2 is a PlayStation 2 emulator for Windows and Linux, started by the same team that brought you PCSX (a Sony PlayStation 1 emulator). Currently, it can emulate thousands of games at full speed
