The usage of mobile video streaming services is growing at a tremendous rate. Given the proliferation of Internet video streaming sites, there is growing interest in understanding the Quality of Experience (QoE) of using these services and the roles of the many factors that contribute to the QoE. QoE has a direct impact on customer retention, which means that poor QoE means loss of revenue for video service providers. The quality of experience of a video streaming service may be objectively evaluated with the use of metrics such as, the amount of buffering during video playback and the time before the video actually starts playing. Collecting this data for analysis on a large scale is quite challenging. In this thesis work we discuss the work done on developing a system for collection and analysis of these metrics. The major part of this work is the development of an mobile application that automates the process of playing a list of videos at configurable intervals and during playback of each video records events of interest such as system statistics, video player events and traffic traces. The application has been published and may be used from different locations to collect a rich data set for detailed analysis and modeling of QoE in mobile Internet video streaming.
