**StreamingBench** evaluates **Multimodal Large Language Models (MLLMs)** in real-time, streaming video understanding tasks. 🌟

## 🎞️ Overview

As MLLMs continue to advance, they remain largely focused on offline video comprehension, where all frames are pre-loaded before making queries. However, this is far from the human ability to process and respond to video streams in real-time, capturing the dynamic nature of multimedia content. To bridge this gap, **StreamingBench** introduces the first comprehensive benchmark for streaming video understanding in MLLMs.

### Key Evaluation Aspects
- 🎯 **Real-time Visual Understanding**: Can the model process and respond to visual changes in real-time?
- 🔊 **Omni-source Understanding**: Does the model integrate visual and audio inputs synchronously in real-time video streams?
- 🎬 **Contextual Understanding**: Can the model comprehend the broader context within video streams?

### Dataset Statistics
- 📊 **900** diverse videos
- 📝 **4,500** human-annotated QA pairs
- ⏱️ Five questions per video at different timestamps

### Performance of Different MLLMs on the Proactive Output Task
*"≤ xs" means that the answer is considered correct if the actual output time is within x seconds of the ground truth.*
