AA-lib is a low level gfx library which does not require graphics device. In fact, there is no graphical output possible. AA-lib replaces those old-fashioned output methods with powerful ascii-art renderer.

SMPEG (SDL MPEG Player Library) is a free MPEG1 video player library with sound support. Video playback is based on the ubiquitous Berkeley MPEG player, mpeg_play v2.2. Audio is played through a slightly modified mpegsound library, part of splay v0.8.2. SMPEG supports MPEG audio (MP3), MPEG-1 video, and MPEG system streams.

Vidstab is a video stabilization library which can be used with FFmpeg. A video acquired using a hand-held camera or a camera mounted on a vehicle typically suffers from undesirable shakes and jitters. Activities such as surfing, skiing, riding and walking while shooting videos are especially prone to erratic camera shakes. Vidstab targets these video contents to help create smoother and stable videos.

Theorafile is a library for quickly and easily decoding Ogg Theora videos. Theorafile was written to be used for FNA's VideoPlayer.

This is a small command line utility used to perform frequency scans for DVB and ATSC transmissions without initial tuning data. It can print the result in several formats:

• VDR channels.conf,

• czap/tzap/xine/mplayer channels.conf,

• Gstreamer dvbsrc plugin,

• VLC xspf playlist,

• XML,

• initial tuning data for scan or dvbv5-scan.

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.

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.

Shotcut is a video editor built on the MLT framework. Features include a wide range of formats through ffmpeg, 4k resolution support, webcam and audio capture, network stream playback, and many more.

This package provides a plugin for adding a gradient Source to OBS Studio.

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

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.

libplacebo is, in a nutshell, the core rendering algorithms and ideas of mpv rewritten as an independent library. As of today, libplacebo contains a large assortment of video processing shaders, focusing on both quality and performance.

SMPEG (SDL MPEG Player Library) is a free MPEG1 video player library with sound support. Video playback is based on the ubiquitous Berkeley MPEG player, mpeg_play v2.2. Audio is played through a slightly modified mpegsound library, part of splay v0.8.2. SMPEG supports MPEG audio (MP3), MPEG-1 video, and MPEG system streams.

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

This package provides an MPRIS (Media Player Remote Interfacing Specification) plugin for the mpv media player. It implements org.mpris.MediaPlayer2 and org.mpris.MediaPlayer2.Player D-Bus interfaces.

To load this plugin, specify the following option when starting mpv: --script $GUIX_PROFILE/lib/mpv-mpris/mpris.so or link it into $HOME/.config/mpv/scripts.

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.

Composite Blur Plugin is a comprehensive blur plugin that provides blur algorithms and types for all levels of quality and computational need.

• Composite Blur provides several highly optimized blur algorithms including Gaussian, Multi-Pass Box, Dual Kawase, and Pixelate.

• Composite Blur provides multiple blur effects to give a different look and feel to the blur including Area, Directional, Zoom, Motion, and Tilt-Shift.

• Composite Blur also allows setting a Background Source so that it can properly composite blurred masks, allowing you to properly layer blurred sources.

• Finally, Composite Blur provides an option to mask where and how much blurring occurs on the source via Crop, Rectangle, Circle, Source, and Image masks.

libass is a subtitle rendering library for the ASS/SSA (Advanced Substation Alpha/SubStation Alpha) subtitle format.

rav1e is an AV1 video encoder. It is designed to eventually cover all use cases, though in its current form it is most suitable for cases where libaom (the reference encoder) is too slow.

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.

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.

Add source to OBS that lets you clone sources to allow different filters than the original.

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

FFmpegthumbnailer is a lightweight video thumbnailer that can be used by file managers to create thumbnails for your video files. The thumbnailer uses ffmpeg to decode frames from the video files, so supported videoformats depend on the configuration flags of ffmpeg.
