Abstract [en]

Video streaming has gained public interest for video conferencing, telecasting, surfing and communicating. The video player plays a vital role in presenting the streaming video which is utmost important for content providers. It has a huge impact on user experience. Wireless networks are vulnerable to noise, interface and have bandwidth limitations. Due to the intrinsic vulnerability of the communication channel and large number of variables involved, simulations alone are not enough in the evaluation of the performance of the wireless networks and performance of the video in the player is to be considered. When there are disturbances or shortages of capacity in the network, network disconnection or sender failure, the video player stops. This research focuses on the performance of the video in the player while streaming over wireless networks. The contribution of this research work is to instrument a video player and to log the disturbances of a streaming video. The disturbances are gathered in terms of timestamps. The timestamps were recorded in the log files by repeating several experiments on different videos. Furthermore, the packet count, memory size allocation and utilization were calculated using PHP scripts. These calculations are used to plot graphs as well as to analyze the performance of the video in the player. The major findings of this research are emptiness of the buffer for audio and video, rebuilding of video frame, triggering re-sampling for audio, also the player response to these findings while playing the video and analyzing them for different types of videos.
