Design and Implementation of WebRTC-Based Video Conference System in Odroid Board

Abstract

This paper presents design of a real-time WebRTC-based video conference system implemented in Odroid embedded board. This research aims to design a low-cost video conference system but with sufficient quality for supporting distant teaching and learning activity. Evaluation of the system was conducted to measure performance of central unit (Odroid board) and video conference application when it was operated on both network with more than 3 Mbps of bandwidth capacity and less than 1 Mbps of bandwidth capacity between two places of around 1 kilometer apart. The results of the evaluation on the central unit show that the video conference application can be executed well in Odroid (50% consumption of CPU usage and 183 MB of memory usage). On the other hand, the results of the evaluation on video conferencing application show that the application can run well under bandwidth of more than 3 Mbps. On network with less than 1 Mbps of bandwidth capacity, the results show that the application can run quite well but with lower performances (higher delays and lower frame rate) with one category on PLR reached the value of 1.714%, exceeding the recommendation of ITU-T with value of 1%. The results of this research show that video conferencing application with sufficient quality of service can be implemented in Odroid.
