git-crypt enables transparent encryption and decryption of files in a git repository. Files which you choose to protect are encrypted when committed, and decrypted when checked out. git-crypt lets you freely share a repository containing a mix of public and private content. git-crypt gracefully degrades, so developers without the secret key can still clone and commit to a repository with encrypted files. This lets you store your secret material (such as keys or passwords) in the same repository as your code, without requiring you to lock down your entire repository.

This package provides a custom transfer agent for Git LFS, allowing plain S3 bucket usage as remote storage for media files. This package uses a standalone agent instead of a server.

Game of Trees (Got) is a version control system which prioritizes ease of use and simplicity over flexibility.

This package is an implementation of Git's wildmatch.c-style pattern matching.

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.

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.

An OBS plugin to record or stream individual OBS sources or scenes. It's an alternative to the Source Record plugin, but more focused on streaming. The plugin can be used to simultaneously stream to multiple platforms, or to record sources to different files providing flexibility during editing.

Matroska aims to become the standard of multimedia container formats. It is based on EBML (Extensible Binary Meta Language), a binary derivative of XML. EBML enables the Matroska Development Team to gain significant advantages in terms of future format extensibility, without breaking file support in old parsers. libebml is a C++ library to read and write EBML files.

This is the VA-API back end required for hardware-accelerated video processing on Intel GEN Graphics devices supported by the i915 driver, such as integrated Intel HD Graphics. It provides access to both hardware and shader functionality for faster encoding, decoding, and post-processing of video formats like MPEG2, H.264/AVC, and VC-1.

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

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.

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).

This program normalizes media files to a certain loudness level using the EBU R128 loudness normalization procedure. It can also perform RMS-based normalization (where the mean is lifted or attenuated), or peak normalization to a certain target level. Batch processing of several input files is possible, including video files.

Pipe-Viewer is a lightweight application for searching and playing videos from YouTube. It parses the YouTube website directly and relies on the Invidious instances only as a fallback method.

x265 is a H.265 / HEVC video encoder application library, designed to encode video or images into an H.265 / HEVC encoded bitstream.

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.

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.

OpenShot Library (libopenshot) is a powerful C++ video editing library with a multi-threaded and feature rich video editing API. It includes bindings for Python, Ruby, and other languages.

The Downstream Keyer can add a Scene to all output, appearing as an overlay in front of all other content. Effectively, it creates a global Scene which exists on all Scenes. The Downstream Keyer plugin can be used for any global elements that should be in all Scenes such as logos, lower thirds or anything done through a Nested Scene.

GTK+ UVC Viewer (guvcview) is a graphical application to control a webcam accessible with Video4Linux (V4L2) and to capture videos and images. It provides control over precise settings of the webcam such as exposure, brightness, contrast, and frame rate.

VLC is a cross-platform multimedia player and framework that plays most multimedia files as well as DVD, Audio CD, VCD, and various streaming protocols.

MKVToolNix provides tools for getting information about Matroska files (mkvinfo), extracting tracks/data from Matroska files (mkvextract), and creating Matroska files from other media files (mkvmerge).

The main motivation for VA-API (Video Acceleration API) is to enable hardware accelerated video decode/encode at various entry-points (VLD, IDCT, Motion Compensation etc.) for prevailing coding standards (MPEG-2, MPEG-4 ASP/H.263, MPEG-4 AVC/H.264, and VC-1/VMW3).

Plugin for OBS Studio which is intended to allow users to apply their own shaders to OBS sources. This theoretically makes possible some simple effects like drop shadows that can be implemented strictly in shader code.
