The Vorbis General Audio Compression Codec
Ogg Vorbis is a fully open, non-proprietary, patent- and royalty-free, general-purpose compressed audio format for audio and music at fixed and variable bitrates. The libvorbis package provides both a standard encoder and decoder runtime libraries under a BSD license.

libEGL are the common dispatch interface for the EGL API.
the user space library that developers compile ALSA applications against
The alsa-lib is a library to interface with ALSA in the Linux kernel and virtual devices using a plugin system. More detail: https://alsa.opensrc.org/Alsa-lib
MMX/SSE2/SIMD accelerated libjpeg-compatible JPEG codec library
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, and ARM systems.
Zlib is a free, general-purpose, not covered by any patents, lossless data-compression library for use on virtually any computer hardware and operating system. The zlib data format is itself portable across platforms.
The X protocol C-language Binding (XCB) is a replacement for Xlib featuring a small footprint, latency hiding, direct access to the protocol, improved threading support, and extensibility.
A library of functions for manipulating PNG image format files
The libpng package contains libraries used by other programs for reading and writing PNG format files. The PNG format was designed as a replacement for GIF and, to a lesser extent, TIFF, with many improvements and extensions and lack of patent problems.
Libogg is a library for manipulating ogg bitstreams. It handles both making ogg bitstreams and getting packets from ogg bitstreams.
System for layout and rendering of internationalized text
Pango is a library for laying out and rendering of text, with an emphasis on internationalization. Pango can be used anywhere that text layout is needed, though most of the work on Pango so far has been done in the context of the GTK+ widget toolkit. Pango forms the core of text and font handling for GTK+. Pango is designed to be modular; the core Pango layout engine can be used with different font backends. The integration of Pango with Cairo provides a complete solution with high quality text handling and graphics rendering.
GStreamer streaming media framework base plugins
GStreamer is a graphics library for built-in media processing components. BasePlug-ins is a the collections used to maintain the GStreamer plugin.
An audio codec for use in low-delay speech and audio communication
Opus is unmatched for interactive speech and music transmission over the Internet, but is also intended for storage and streaming applications. It is standardized by the Internet Engineering Task Force (IETF) as RFC 6716 which incorporated technology from Skype’s SILK codec and Xiph.Org’s CELT codec.
libGL and libGLX are the common dispatch interface for the GLX API.
A thin layer of types for graphic libraries.
Graphene provides a small set of mathematical types needed to implement graphic libraries that deal with 2D and 3D transformations and projections.
Cairo is a 2D graphics libarary with support for multiple output devices. It provides high-quality display and print output and this package also contains functionality to make cairo graphics library integrate well with GObject used by GNOME.
library for the X Video extension to the X Window System

Bindings for GStreamer 1.0, the open source multimedia framework
GStreamer1 implements a framework that allows for processing and encoding of multimedia sources in a manner similar to a shell pipeline. Because it's introspection-based, most of the classes follow directly from the C API. Therefore, most of the documentation is by example rather than a full breakdown of the class structure.
Wayland is a protocol for a compositor to talk to its clients as well as a C library implementation of that protocol. The compositor can be a standalone display server running on Linux kernel modesetting and evdev input devices, an X application, or a wayland client itself. The clients can be traditional applications, X servers (rootless or fullscreen) or other display servers. Part of the Wayland project is also the Weston reference implementation of a Wayland compositor. Weston can run as an X client or under Linux KMS and ships with a few demo clients. The Weston compositor is a minimal and fast compositor and is suitable for many embedded and mobile use cases.
libXi is the client-side library for the X Input Extension.
Orc is the sucessor to Liboil - The Library of Optimized Inner Loops. Orc is a library and set of tools for compiling and executing very simple programs that operate on arrays of data. The "language" is a generic assembly language that represents many of the features available in SIMD architectures, including saturated addition and subtraction, and many arithmetic operations.
The GNU C Library project provides the core libraries for the GNU system and GNU/Linux systems, as well as many other systems that use Linux as the kernel. These libraries provide critical APIs including ISO C11, POSIX.1-2008, BSD, OS-specific APIs and more. These APIs include such foundational facilities as open, read, write, malloc, printf, getaddrinfo, dlopen, pthread_create, crypt, login, exit and more.
The core library that forms the basis for projects such as GTK+ and GNOME
GLib is a bundle of three (formerly five) low-level system libraries written in C and developed mainly by GNOME. GLib's code was separated from GTK, so it can be used by software other than GNOME and has been developed in parallel ever since.
The X.Org project provides an open source implementation of the X Window System. X.Org X11 libXext contains runtime library.
Libvisual is a library that acts as a middle layer between applications that want audio visualization, and audio visualization plugins. It is middleware aimed at providing a common interface between application developers with a need for audio visualization and developers who write visualizations.
This project provides lists of various ISO standards (e.g. country, language, language scripts, and currency names) in one place, rather than repeated in many programs throughout the system.
Theora is a free and open video compression format from the Xiph.org Foundation. Like all our multimedia technology it can be used to distribute film and video online and on disc without the licensing and royalty fees or vendor lock-in associated with other formats. devel-docs The libtheora-devel-docs package contains the documentation needed to develop applications with libtheora.
Introspection system for GObject-based libraries
GObject Introspection can scan C header and source files in order to generate introspection "typelib" files. It also provides an API to examine typelib files, useful for creating language bindings among other things.
