This plugin adds 3 sources for capturing audio outputs, inputs and applications using PipeWire.

The v4l-utils provide a series of libraries and utilities to be used for realtime video capture via Linux-specific APIs.

L-SMASH is a cross-platform library that handles the ISO base media file format and some of its derived file formats, including MP4. It operates as a multiplexer and demultiplexer, and can mux video and audio in several formats using standalone executable files.

qtfaststart enables streaming and pseudo-streaming of QuickTime and MP4 files by moving metadata and offset information to the beginning of the file. It can also print some useful information about the structure of the file. This program is based on qt-faststart.c from the FFmpeg project, which is released into the public domain, as well as ISO 14496-12:2005 (the official spec for MP4), which can be obtained from the ISO or found online.

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

Libcaption creates and parses closed-caption data, providing an encoder / decoder for the EIA608 and CEA708 closed-caption standards.

608 support is currently limited to encoding and decoding the necessary control and preamble codes as well as support for the Basic North American, Special North American and Extended Western European character sets.

708 support is limited to encoding the 608 data in NTSC field 1 user data type structure.

In addition, utility functions to create h.264 SEI (Supplementary enhancement information) NALUs (Network Abstraction Layer Unit) for inclusion into an h.264 elementary stream are provided.

Openh264 is a library which can decode H264 video streams.

SimpleScreenRecorder is an easy to use screen recorder with a graphical user interface. It supports recording the entire screen, or a part of it, and allows encoding in many different codecs and file formats. Other features include a live preview and live streaming.

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.

OBS Advanced Masks is a project designed to expand the masking functionalities within OBS Studio. This plug-in provides filters for users to create intricate and customized masks for their OBS Scenes and Sources.

• Advanced Masks provides both Alpha Masking and Adjustment Masking.

• Shape masks allow for dynamically generated Rectangle, Circle, Elliptical, Regular Polygon, Star, and Heart shaped masks, with many adjustable parameters.

• Source Masks allow an existing OBS source to be used as a mask, using any combination of the red, green, blue, or alpha channels from said source.

• Image Masks include all of the same functionality as Source Masks, but applied via a static image (.png, .jpeg, etc).

• Gradient Masks allow a fading mask using a user-specified gradient.

Libmms is a library for streaming media files using the mmst and mmsh protocols.

Libmpeg3 decodes MP2, MP3, AC3, MPEG-1 video, MPEG-2 video, and DVD footage in a single library. It supports many esoteric features like parallel video decoding, frame-accurate editing, YUV 4:2:2, and ATSC transport stream decoding

mpv is a general-purpose audio and video player. It is a fork of mplayer2 and MPlayer. It shares some features with the former projects while introducing many more.
