This code forms a set of C++ libraries for multimedia streaming, using open standard protocols (RTP/RTCP, RTSP, SIP). The libraries can be used to stream, receive, and process MPEG, H.265, H.264, H.263+, DV or JPEG video, and several audio codecs. They can easily be extended to support additional (audio and/or video) codecs, and can also be used to build basic RTSP or SIP clients and servers.

dav1d is a new AV1 cross-platform decoder, and focused on speed and correctness.

Scalable Video Technology (SVT) is a software-based video coding technology that is highly optimized for Intel's Xeon processors. Using the SVT-HEVC encoder, it is possible to spread video encoding processing across multiple Intel's Xeon processors to achieve a real advantage of processing efficiency. Note that this package requires the AVX2 instruction, which means it will not work on older x86_64 CPUs such as the Core 2 Duo.

Gavl is short for Gmerlin Audio Video Library. It is a low level library, upon which multimedia APIs can be built. Gavl handles all the details of audio and video formats like colorspaces, sample rates, multichannel configurations, etc. It provides standardized definitions for those formats as well as container structures for carrying audio samples or video images inside an application.

In addition, it handles the sometimes ugly task of converting between all these formats and provides some elementary operations (copying, scaling, alpha blending etc).

Frei0r is a minimalistic plugin API for video effects. The main emphasis is on simplicity for an API that will round up the most common video effects into simple filters, sources and mixers that can be controlled by parameters. Frei0r wants to provide a way to share these simple effects between many applications, avoiding their reimplementation by different projects. It counts more than 100 plugins.

MPlayer is a movie player. It plays most MPEG/VOB, AVI, Ogg/OGM, VIVO, ASF/WMA/WMV, QT/MOV/MP4, RealMedia, Matroska, NUT, NuppelVideo, FLI, YUV4MPEG, FILM, RoQ, PVA files. One can watch VideoCD, SVCD, DVD, 3ivx, DivX 3/4/5, WMV and H.264 movies.

OpenTimelineIO is an interchange format and API for editorial cut information. OTIO contains information about the order and length of cuts and references to external media. It is not however, a container format for media.

For integration with applications, the core OTIO library is implemented in C++ and provides an in-memory data model, as well as library functions for interpreting, manipulating, and serializing that data model. Within the core is a dependency-less library for dealing strictly with time, opentime.

GPAC is a multimedia framework focused on modularity and standards compliance. GPAC provides tools to process, inspect, package, stream, playback and interact with media content. Such content can be any combination of audio, video, subtitles, metadata, scalable graphics, encrypted media, 2D/3D graphics and ECMAScript.

OpenShot takes your videos, photos, and music files and helps you create the film you have always dreamed of. Easily add sub-titles, transitions, and effects and then export your film to many common formats.

Vdpauinfo is a tool to query the capabilities of a VDPAU implementation.

MediaInfo is a utility used for retrieving technical information and other metadata about audio or video files. It supports the many codecs and formats supported by libmediainfo.

libbdplus is a library which implements the BD+ System specifications.

qtfaststart enables streaming and pseudo-streaming of QuickTime and MP4 files by moving metadata and offset information to the beginning of the file. It can also print some useful information about the structure of the file. This program is based on qt-faststart.c from the FFmpeg project, which is released into the public domain, as well as ISO 14496-12:2005 (the official spec for MP4), which can be obtained from the ISO or found online.

The MP4v2 library provides an API to create and modify mp4 files as defined by ISO-IEC:14496-1:2001 MPEG-4 Systems. This file format is derived from Apple's QuickTime file format that has been used as a multimedia file format in a variety of platforms and applications. It is a very powerful and extensible format that can accommodate practically any type of media.

SVT-VP9 is a VP9 video encoder implementation. It is focused on supporting video-on-demand and live encoding on Intel Xeon processors.

Gaupol supports multiple subtitle file formats and provides means of creating subtitles, editing texts and timing subtitles to match video. The user interface features a builtin video player and is designed with attention to convenience of translating and batch processing of multiple documents.

SMPlayer is a graphical user interface (GUI) for MPlayer, which is capable of playing almost all known video and audio formats. Apart from providing access for the most common and useful options of MPlayer, SMPlayer adds other interesting features like the possibility to play Youtube videos, download subtitles, remember the last played position, etc.

Libaom is the reference implementation of AV1. It includes a shared library and encoder and decoder command-line executables.

yt-dlp is a small command-line program to download videos from YouTube.com and many more sites. It is a fork of youtube-dl with a focus on adding new features while keeping up-to-date with the original project.

Xvid is an MPEG-4 Part 2 Advanced Simple Profile (ASP) video codec library. It uses ASP features such as b-frames, global and quarter pixel motion compensation, lumi masking, trellis quantization, and H.263, MPEG and custom quantization matrices.

libmpeg2 is a library which can decode MPEG1 and MPEG2 video streams.

This is a collection of utilities to query and test the VA-API implemented by the libva library.

These tools require a supported graphics chip, driver, and VA-API back end to operate properly.

SVT-AV1 is an AV1 codec implementation. The encoder is a work-in-progress, aiming to support video-on-demand and live streaming applications with high performance requirements. It mainly targets Intel-compatible CPUs (x86), but has limited support for other architectures.

FFmpeg is a complete, cross-platform solution to record, convert and stream audio and video. It includes the libavcodec audio/video codec library.
