intel/video-caption-service repository overview

⁠Live Video Captioning Microservice

This microservice demonstrates AI-powered captioning for multiple live RTSP video streams using Intel® DL Streamer and OpenVINO™ Vision Language Models (VLMs). It enables real-time understanding and natural language description of video content, showcasing how modern vision-language AI can be applied to streaming video analytics pipelines.

⁠Highlights

🎥 Live RTSP Ingestion – Continuous processing of IP camera or streaming sources

🧠 Vision‑Language Captioning – Prompt‑driven captions via OpenVINO VLMs

⚡ Intel‑Optimized Inference – Low‑latency, high‑throughput execution

📡 WebRTC Preview – Real‑time video preview alongside captions

📊 Performance Metrics – CPU/GPU/RAM usage and inference stats

🔄 Multi‑Model Support – Easy switching between supported VLMs

⁠Typical Use Cases

• Smart video analytics and surveillance demos
• Accessibility through live AI‑generated captions
• Benchmarking VLM performance on Intel® platforms
• Edge AI proofs‑of‑concept for real‑time video understanding
