HandBrake is a tool for converting video from any format to a selection of modern, widely supported codecs.

GTK+ UVC Viewer (guvcview) is a graphical application to control a webcam accessible with Video4Linux (V4L2) and to capture videos and images. It provides control over precise settings of the webcam such as exposure, brightness, contrast, and frame rate.

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.

libbluray is a library designed for Blu-Ray Disc playback for media players, like VLC or MPlayer.

OpenShot Library (libopenshot) is a powerful C++ video editing library with a multi-threaded and feature rich video editing API. It includes bindings for Python, Ruby, and other languages.

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.

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

Plugin for OBS Studio to move source to a new position during scene transition.

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

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

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.
