Open Source Assembly Video Software

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.

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.

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.

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.

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.

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.

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!

ffdshow is DirectShow and VFW codec for decoding/encoding many video and audio formats, including DivX and XviD movies using libavcodec, xvid and other opensourced libraries with a rich set of postprocessing filters.

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.

DVDx 4.0 is a very easy to use audio/video encoder and a powerful DVD copier. Read DVDs and audio/video files, encode to popular video formats: (S)VCD/CVD/DVD, Xvid/Divx, MPEG-4, H.264/AVC, QuickTime, Flash Video, Ogg, WebM, AC.3, MP3, MP4/AAC etc.

Universal Video Capture driver for WinMe,Win2000,WinXP and Win98SE for Bt848/Bt878 based capture cards

VirtualDub APNG Mod is created to provide Animated PNG support for the popular video editing software VirtualDub. Export module is designed to compress the output files as much as possible. Internal input driver can load APNG files, for more editing.

Downloads are now available at https://artemiourbina.itch.io/240p-test-suite A homebrew software suite for video game consoles developed to help in the evaluation of upscalers, upscan converters, line doublers and of course TV processing of 240p video. The Wii and Dreamcast versions have modes for 480i and 480p evaluation as well. It has tests designed with the processing of 240p signals in mind, although when possible it includes other video modes and specific tests for them. These have been tested with video processors on real hardware and a variety of displays, including CRTs and Arcade monitors via RGB. As a secondary target, the suite aims to provide tools for calibrating colors, black and white levels for specific console outputs and setups. Current platforms are: Sega Genesis (Mega Drive), Sega CD (Mega CD), PC Engine/Turbografx-16, Super CD-ROM2/CD-ROM2, NES/Famicom, Super Nintendo/Super Famicom, Sega Dreamcast, Nintendo Wii and GameCube.

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.

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.

This project contains useful software tools to create a NBTV (Narrow Band Television) video source (+audio, and optionally with color) on a classical 2-channel PC audio output. It also includes a document on a hardware example explained in details, as well as how to use software tools.
