Experimental testbed for video streaming analysis based on RTMF protocol

Abstract

Internet-based video communications have been gaining increasing popularity in recent years and thus, the need for improving quality of service has become an essential requirement. This paper presents an experimental testbed that is based on the real-time media flow protocol (RTMFP). The proposed testbed enables experimental investigations of the impact of key video-quality parameters such as the frame quality, frame rate, and resolution on the video quality at various speeds of video streaming, and network conditions. It also allows for developing adaptation algorithms that can be utilized in real-time video transmission to ensure delivery of best service possible under various network conditions. The hardware and software aspects of the testbed are presented along with the practical setup and configuration commands. Some of the practical challenges faced throughout the implementation and test phases are presented. Performance of the developed prototype is assessed experimentally and some of the obtained results are also presented and discussed.
