Performance evaluation of stack-protocols, encapsulation methods and video codecs for live video streaming

There are diverse factors involved in the transmission of live video over internet. These factors have direct impact on the quality of the transmitted video. The underlying protocol, encapsulation method and the choice of video codec are the key factors involved in the transmission of video over streaming network. Up to our knowledge various studies have been performed to analyze the impact of these factors individually on the quality of video transmission however their joint impact on video transmission is not yet done. In this paper we characterize the performance of live video streaming setup, while keeping in view the effect of stack-protocol, encapsulation method and the underlying video codec on delay as the key investigating parameter. The results obtained while considering diverse video streaming setups are provided in the results section of this paper. More specifically, it was observed that stack (http, mjpeg, mjpeg) performs best and stack (mms, asf, wmv1) perform worst.
