Media Reference Stack Release Notes
The Media Reference Stack supports analytics and transcode workloads, built on Intel® Xeon® Scalable Platforms and featuring software optimizations at each layer. Customers, developers and CSPs who use this stack can gain a significant performance boost, from hardware up through the application layer.
The Media Reference Stack is containerized software integrating industry-leading components:
FFmpeg*, an open source project consisting of a vast software suite of libraries and programs for handling video, audio, and other multimedia files and streams
GStreamer* a pipeline-based multimedia framework which links together a wide variety of media processing systems to complete complex workflows
x264, an open source library and command-line utility developed for encoding video streams
Scalable Video Technology (SVT), a software-based video coding technology that allows encoders to achieve, on Intel® Xeon Scalable processors, the best possible trade-offs between performance, latency, and visual quality: AV1 & HEVC
Intel® OpenVINO (™) toolkit, an Open Visual Inference and Neural Network optimized toolkit, provides developers with improved neural network performance on a variety of Intel® processors and helps them further unlock cost-effective, real-time vision applications.
The Media Reference Stack is designed to accelerate offline and live media processing, analytics, and inference recommendations for real-world use cases such as smart city applications, immersive media enhancement, video surveillance, and product placement.
