FFmpeg Video Analytics (FFVA) Plugin

Overview

This repository contains FFmpeg patches that enable CNN model-based video analytics capabilities in the FFmpeg framework. These patches contain filter based implementation include such things as object detection, classification, and recognition. Following is an example that runs detection & emotion classification, using specific models on a video file:

ffmpeg -i test.mp4 -vf detect=model=face-detection-adas-0001.xml:model_proc=face-detection-adas-0001.json,classify=model=emotions-recognition-retail-0003.xml:model_proc=emotions-recognition-retail-0003.json -an -f null -

The solution leverages:

  • Open-source FFmpeg framework for pipeline management
  • FFmpeg components for input and output, such as media files and real-time streaming from a camera or network
  • Video decode and encode plugins, including either CPU-optimized plugins or GPU-accelerated plugins, based on VAAPI

In addition, the solution installs the following Deep Learning-specific elements, also available in this repository:

  • Inference plugins leveraging OpenVINO™ Toolkit for high-performance inference using CNN models
  • Visualization of computer vision results (such as bounding boxes and labels of detected objects) on top of video stream
