liba52 is a library for decoding ATSC A/52 audio streams. The A/52 standard is used in a variety of applications, including digital television and DVD. It is also known as AC-3.

Many applications can use VDPAU to accelerate portions of the video decoding process and video post-processing to the GPU video hardware. Since there is no VDPAU available on Intel chips, they fall back to different drawing techniques. This driver uses OpenGL under the hood to accelerate drawing and scaling and VA-API (if available) to accelerate video decoding.

TSLib is a cross-platform library that provides access to touchscreen devices and the ability to apply filters to their input events.

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.

This package provides a command-line interface for Twitch.tv

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.

svtplay-dl allows downloading TV programmes from various Swedish broadcasters including SVT Play, Sveriges Radio, TV4 Play, along with many others.

This OBS plugin allows you to capture the screen on wlroots-based Wayland compositors.

Scalable Video Technology (SVT) is a software-based video coding technology that is highly optimized for Intel's Xeon processors. Using the SVT-HEVC encoder, it is possible to spread video encoding processing across multiple Intel's Xeon processors to achieve a real advantage of processing efficiency. Note that this package requires the AVX2 instruction, which means it will not work on older x86_64 CPUs such as the Core 2 Duo.

wf-recorder is a utility program for screen recording of wlroots-based compositors. More specifically, those that support wlr-screencopy-v1 and xdg-output.

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.

Aegisub is a tool for creating and modifying subtitles. Aegisub makes it quick and easy to time subtitles to audio, and features many powerful tools for styling them, including a built-in real-time video preview.

Syncplay is a solution to synchronize video playback across multiple instances of media players over the Internet. When one person pauses/unpauses playback or skips to a position in the video, this is replicated across all media players connected to the same server and in the same "room" (viewing session). A built-in text chat for discussing the synced media is also included for convenience.

The mpvpaper package provides a wallpaper program for wlroots-based wayland compositors, allowing you to play videos as your wallpaper using mpv.

FFMpegSource is a wrapper library around ffmpeg/libav that allows programmers to access a standard API to open and decompress media files.

Avidemux is a video editor designed for simple cutting, filtering and encoding tasks. It supports many file types, including AVI, DVD compatible MPEG files, MP4 and ASF, using a variety of codecs. Tasks can be automated using projects, job queue and powerful scripting capabilities.

This package shows the keys that the user presses on the screen.

Presumably, that's because you are presenting the screen to someone else that should see the keys.

This package works in Xorg and Wayland since it directly reads the keys from the evdev device via libinput.

Users in group ``wheel'' can skip password authentication.

Streamlink is command-line utility that extracts streams from sites like Twitch.tv and pipes them into a video player of choice.

This package provides the GameStream code shared between Moonlight clients.

Movit is a high-quality, high-performance library for GPU-accelerated video filtering built on modern OpenGL. It provides a compact set of carefully implemented filters designed for predictable real-time performance and visually accurate results, supporting OpenGL 3.0 or GLES 3.0.

Included filters provide blur, diffusion, FFT-based convolution, glow, color correction (lift/gamma/gain), mirror, luma-based transitions, Porter-Duff overlay composition, bilinear and Lanczos scaling, sharpening (unsharp mask and Wiener), saturation, vignette, white balance and YADIF deinterlacing.

libdca is a library for decoding DTS Coherent Acoustics streams.

Command line application that copies JPEG frames from one or more input plugins to multiple output plugins. It can be used to stream JPEG files over an IP-based network from a webcam to various types of viewers such as Chrome, Firefox, Cambozola, VLC, mplayer, and other software capable of receiving MJPG streams.

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

Libdvdnav is a library for developers of multimedia applications. It allows easy use of sophisticated DVD navigation features such as DVD menus, multiangle playback and even interactive DVD games. All this functionality is provided through a simple API which provides the DVD playback as a single logical stream of blocks, intermitted by special dvdnav events to report certain conditions. The main usage of libdvdnav is a loop regularly calling a function to get the next block, surrounded by additional calls to tell the library of user interaction. The whole DVD virtual machine and internal playback states are completely encapsulated.
