Adaptive Video Encoder for Network Bandwidth Drops in Real-Time Communication
Hua Meng, Xiangjie Huang, Zili Meng · 2025
Real-time communication (RTC) is crucial in digital life, with latency significantly affecting user experience. Latency spikes often occur due to mismatches between video codec bitrates and network capacity, especially during sudden bandwidth drops. Current video encoders adjust bitrates too slowly, increasing latency. This poster suggests that encoders should adapt more quickly to network changes by dynamically adjusting codec parameters, maintaining compression efficiency. Preliminary tests with the x264 codec show these strategies can reduce latency by 28.66% to 78.87% while slightly improving video quality by 0.8% to 3%.
