Media Lovin' Toolkit (MLT) is an open source software multimedia framework, designed and developed for television broadcasting. It provides a toolkit for broadcasters, video editors, media players, transcoders, web streamers and many more types of applications. The functionality of the system is provided via an assortment of ready to use tools, XML authoring components, and an extensible plug-in based API.

It is used by video editors Kdenlive and Shotcut among others. [2]

Technical overview

MLT provides an API with minimal dependencies (POSIX and C99). The design is modular allowing for the addition of new components and making integration simple with other multimedia libraries and applications. Support is available for the authoring and manipulation of time-based media including playlists, multiple tracks, filters, and transitions using DOM.

High-level language bindings exist for C++, Java, Lua, Perl, PHP, Python, Ruby, and Tcl. MLT takes advantage of multi-core processors and GPU processing.

MLT has a modular design that supports multiple libraries like FFmpeg and Jack. Through FFmpeg, MLT is able to support nearly all audio and video formats with optimized operations. Video and audio effects include image scaling, alpha-compositing, deinterlacing, masking, motion-tracking, audio mixing, audio gain, and wipe transitions.

Other features include:

<span class="mw-page-title-main">XML</span> Markup language by the W3C for encoding of data

Extensible Markup Language (XML) is a markup language and file format for storing, transmitting, and reconstructing arbitrary data. It defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. The World Wide Web Consortium's XML 1.0 Specification of 1998 and several other related specifications—all of them free open standards—define XML.

MPEG-7 is a multimedia content description standard. It was standardized in ISO/IEC 15938. This description will be associated with the content itself, to allow fast and efficient searching for material that is of interest to the user. MPEG-7 is formally called Multimedia Content Description Interface. Thus, it is not a standard which deals with the actual encoding of moving pictures and audio, like MPEG-1, MPEG-2 and MPEG-4. It uses XML to store metadata, and can be attached to timecode in order to tag particular events, or synchronise lyrics to a song, for example.

FFmpeg is a free and open-source software project consisting of a suite of libraries and programs for handling video, audio, and other multimedia files and streams. At its core is the command-line ffmpeg tool itself, designed for processing of video and audio files. It is widely used for format transcoding, basic editing, video scaling, video post-production effects and standards compliance.

X3D is a set of royalty-free ISO/IEC standards for declaratively representing 3D computer graphics. X3D includes multiple graphics file formats, programming-language API definitions, and run-time specifications for both delivery and integration of interactive network-capable 3D data. X3D version 4.0 has been approved by Web3D Consortium, and is under final review by ISO/IEC as a revised International Standard (IS).

<span class="mw-page-title-main">Visual programming language</span> Programming language written graphically by a user

In computing, a visual programming language or block coding is a programming language that lets users create programs by manipulating program elements graphically rather than by specifying them textually. A VPL allows programming with visual expressions, spatial arrangements of text and graphic symbols, used either as elements of syntax or secondary notation. For example, many VPLs are based on the idea of "boxes and arrows", where boxes or other screen objects are treated as entities, connected by arrows, lines or arcs which represent relations.

OpenMAX, often shortened as "OMX", is a non-proprietary and royalty-free cross-platform set of C-language programming interfaces. It provides abstractions for routines that are especially useful for processing of audio, video, and still images. It is intended for low power and embedded system devices that need to efficiently process large amounts of multimedia data in predictable ways, such as video codecs, graphics libraries, and other functions for video, image, audio, voice and speech.

<span class="mw-page-title-main">Kino (software)</span> Linux video editor

Kino is a discontinued free software GTK+-based video editing software application for Linux and other Unix-like operating systems. The development of Kino was started at the end of 2000 by Dan Dennedy and Arne Schirmacher. The project's aim was: "Easy and reliable DV editing for the Linux desktop with export to many usable formats." The program supported many basic and detailed audio/video editing and assembling tasks.

A multimedia framework is a software framework that handles media on a computer and through a network. A good multimedia framework offers an intuitive API and a modular architecture to easily add support for new audio, video and container formats and transmission protocols. It is meant to be used by applications such as media players and audio or video editors, but can also be used to build videoconferencing applications, media converters and other multimedia tools. Data is processed among modules automatically, it is unnecessary for app to pass buffers between connected modules one by one.

LiVES (LiVES Editing System) is a free and open-source video editing software and VJ tool, released under the GNU General Public License version 3 or later. There are binary versions available for most popular Linux distributions (including Debian, Ubuntu, Fedora, Suse, Gentoo, Slackware, Arch Linux, Mandriva and Mageia). There are also ports for BSD, and it will run under Solaris and IRIX. It has been compiled under OS X Leopard, but not thoroughly tested on that platform. In early 2019, a version for Microsoft Windows was announced, with a release slated for in the second half of 2019.

In the field of digital and interactive television, Nested Context Language (NCL) is a declarative authoring language for hypermedia documents. NCL documents do not contain multimedia elements such as audio or video content; rather they function as a "glue" language that specifies how multimedia components are related. In particular, NCL documents specify how these components are synchronized relative to each other and how the components are composed together into a unified document. Among its main facilities, it treats hypermedia relations as first-class entities through the definition of hypermedia connectors, and it can specify arbitrary semantics for a hypermedia composition using the concept of composite templates.

The Oxygen XML Editor is a multi-platform XML editor, XSLT/XQuery debugger and profiler with Unicode support. It is a Java application so it can run in Windows, Mac OS X, and Linux. It also has a version that can run as an Eclipse plugin.

FFV1 is a lossless intra-frame video coding format. It can use either variable-length coding or arithmetic coding for entropy coding. The encoder and decoder are part of the free, open-source library libavcodec in the project FFmpeg since June 2003. FFV1 is also included in ffdshow and LAV Filters, which makes the video codec available to Microsoft Windows applications that support system-wide codecs over Video for Windows (VfW) or DirectShow. FFV1 is particularly popular for its performance regarding speed and size, compared to other lossless preservation codecs, such as M-JPEG2000. The European Broadcasting Union (EBU) lists FFV1 under the codec-family index "31" in their combined list of video codec references.

Windows Vista has many significant new features compared with previous Microsoft Windows versions, covering most aspects of the operating system.
