In computing, cross-platform software is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms.
JACK Audio Connection Kit is a professional sound server API and pair of daemon implementations to provide real-time, low-latency connections for both audio and MIDI data between applications. JACK was developed by a community of open-source developers led by Paul Davis and has been a key piece of infrastructure and the de facto standard for professional audio software on Linux since its inception in 2002. The server is free software, licensed under GPL-2.0-or-later, while the library is licensed under LGPL-2.1-or-later.
freedesktop.org (fd.o), formerly X Desktop Group (XDG), is a project to work on interoperability and shared base technology for free-software desktop environments for the X Window System (X11) and Wayland on Linux and other Unix-like operating systems. Although freedesktop.org produces specifications for interoperability, it is not a formal standards body.
GStreamer is a pipeline-based multimedia framework that links together a wide variety of media processing systems to complete complex workflows. For instance, GStreamer can be used to build a system that reads files in one format, processes them, and exports them in another. The formats and processes can be changed in a plug and play fashion.
Gnash is a media player for playing SWF files. Gnash is available both as a standalone player for desktop computers and embedded devices, as well as a plugin for the browsers still supporting NPAPI. It is part of the GNU Project and is a free and open-source alternative to Adobe Flash Player. It was developed from the gameswf project.
Pitivi is a free and open-source non-linear video editor for Linux, developed by various contributors from free software community and the GNOME project, with support also available from Collabora. Pitivi is designed to be the default video editing software for the GNOME desktop environment. It is licensed under the terms of the GNU Lesser General Public License.
Phonon is the multimedia API provided by KDE and is the standard abstraction for handling multimedia streams within KDE software and also used by several Qt applications.
PulseAudio is a network-capable sound server program distributed via the freedesktop.org project. It runs mainly on Linux, including Windows Subsystem for Linux on Microsoft Windows and Termux on Android; various BSD distributions such as FreeBSD, OpenBSD, and macOS; as well as Illumos distributions and the Solaris operating system. It serves as a middleware in between applications and hardware and handles raw PCM audio streams.
Moonlight is a discontinued free and open source implementation for Linux and other Unix-based operating systems of the Microsoft Silverlight application framework, developed and then abandoned by the Mono Project. Like Silverlight, Moonlight was a web application framework which provided capabilities similar to those of Adobe Flash, integrating multimedia, graphics, animations and interactivity into a single runtime environment.
Video Acceleration API (VA-API) is an open source application programming interface that allows applications such as VLC media player or GStreamer to use hardware video acceleration capabilities, usually provided by the graphics processing unit (GPU). It is implemented by the free and open-source library libva, combined with a hardware-specific driver, usually provided together with the GPU driver.
Collabora Ltd is a global private company headquartered in Cambridge, United Kingdom, with offices in Cambridge and Montreal. It provides open-source consultancy, training and products to companies.
Moblin, short for 'mobile Linux', is a discontinued open source operating system and application stack for Mobile Internet Devices (MIDs), netbooks, nettops and embedded devices.
Hollywood is a commercially distributed programming language developed by Andreas Falkenhahn which mainly focuses on the creation of multimedia-oriented applications. Hollywood is available for AmigaOS, MorphOS, WarpOS, AROS, Windows, macOS, Linux, Android, and iOS. Hollywood has an inbuilt cross compiler that can automatically save executables for all platforms supported by the software. The generated executables are completely stand-alone and do not have any external dependencies, so they can also be started from a USB flash drive. An optional add-on also allows users to compile projects into APK files.
ModPlug Player is a module file player developed by Olivier Lapicque in conjunction with the original ModPlug Tracker project and the ModPlug Browser plugin. Features include a playlist editor, graphical equalizer, automatic gain control, bass expansion, reverb, Dolby Surround Sound support and the ability to mix two modules simultaneously and to change their pitch and tempo. The player supports a variety of module music files in both native and compressed formats.
LibreOffice is a free and open-source office productivity software suite, a project of The Document Foundation (TDF). It was forked in 2010 from OpenOffice.org, an open-sourced version of the earlier StarOffice. It consists of programs for word processing; creating and editing spreadsheets, slideshows, diagrams, and drawings; working with databases; and composing mathematical formulae. It is available in 120 languages. TDF does not provide support for LibreOffice, but enterprise-focused editions are available from companies in the ecosystem.
Long-term support (LTS) is a product lifecycle management policy in which a stable release of computer software is maintained for a longer period of time than the standard edition. The term is typically reserved for open-source software, where it describes a software edition that is supported for months or years longer than the software's standard edition.
PipeWire is a server for handling audio, video streams, and hardware on Linux. It was created by Wim Taymans at Red Hat. It handles multimedia routing and pipeline processing.
Collabora Online is an open source online office suite built on LibreOffice technology, enabling web-based collaborative real-time editing of word processing documents, spreadsheets, presentations, and vector graphics. Optional apps are available for desktops, laptops, tablets, smartphones, and Chromebooks.
