Live Demonstration: Interactive Quality of Experience Evaluation in Kvazzup Video Call

This paper presents an interactive demonstration setup, which allows users to configure the video coding parameters of Kvazzup open-source video call software at runtime and evaluate their impact on Quality of Service (QoS) and Quality of Experience (QoE). The demonstration is carried out by implementing a new Kvazzup control panel for video call parameterization and visual quality, bit rate, latency, and frame rate evaluation.
