VSR-Bench: An Open-Source Platform for Browser-Native Real-Time VSR Evaluation in WebRTC

Designed and implemented VSR-Bench, the first browser-native benchmarking platform for real-time VSR in WebRTC, supporting multiple models, execution architectures, and GPU backends. Showed that WebGPU enables 13× lower latency and 30.4% lower GPU memory usage, making real-time VSR feasible under strict latency constraints.
