libavif
Library for encoding and decoding .avif files
libavif is a portable, open-source C library that implements encoding and decoding for the AVIF (AV1 Image File Format), offering a robust, production-ready way to work with AVIF images across platforms. It supports all AV1-supported YUV formats and bit-depths, including alpha (transparency), and includes command-line tools (avifenc and avifdec) to easily convert to/from AVIF from common image formats like JPEG, PNG, or Y4M. The API is straightforward, allowing applications to integrate AVIF support natively — creating, decoding, compressing, or decompressing images programmatically. Recent developments have added experimental support for HDR gain maps, improved color-space handling (including wide color gamut and high bit depth), and better quality tuning modes for encoding, making libavif a cutting-edge tool for high-quality image compression. -

AV1 AVIF
AV1 Image File Format Specification - ISO-BMFF/HEIF derivative
...The project outlines the syntax and semantics required for AVIF compliance, including support for multiple image profiles, color depths, chroma subsampling modes, HDR/WCG, alpha channels, animation/image sequences, and various color-space/bit-depth combinations — making AVIF a versatile, modern image format suitable for both simple photos and advanced imagery needing high fidelity. The specification ensures interoperability across encoders and decoders, providing guidelines so that images created by any compliant AVIF encoder can be reliably decoded by compliant decoders. ... -

GLMixer
Graphic Live Mixer
GLMixer performs real time graphical blending of several movie clips and of computer generated graphics. Drop video files in the mixing workspace and place them in a circular area to change their opacity ; if you selects two videos, moving them together performs a fading transition. This principle generalizes to a large number of videos. Direct interaction with the video allows to be fast and reactive, and to move and deform them on screen. The output of your operations is shown in the... -

FSM: Font System Manager
FSM is a tool designed to bridge the gap between ImageMagick & paperjs
ImageMagick and browser-based tools such as paperjs use very different engines for font rendering. This makes it difficult to reproduce accurately effects, for example, in video projects where the placement of text, sub-images, etc needs to be tested before production. While paperjs will render a scene in a browser context, it cannot be used in production, where ImageMagick is necessary. FSM allows for the classification of usable fonts for both these interfaces, accurate measurement of... -

SVCEval-RA
An Evaluation Framework for Adaptive Scalable Video Streaming
SVCEval-RA is a simulation framework for rate-adaptive video transmission using the Scalable Video Coding standard (H.264/SVC). Our approach uses feedback information about the available bandwidth to allow the video source to select the most suitable combination of SVC layers for the transmission of the video sequence. The proposed solution has been integrated into the network simulator NS-2 in order to support realistic network simulations. -
