基于視頻分享社交系統(tǒng)后臺的設(shè)計與研發(fā)
[Abstract]:In recent years, with the popularity of smart phones, smart terminals beyond the PC (Personal Computer) machine become the mainstream, people have formally entered the era of mobile interconnection. With the advent of mobile Internet era, a personalized recommendation era in front of people, every ordinary people want to record the wonderful moments of life and share with friends and family at the same time. However, the current market video capture software, the function is very single, so under this background, a kind of video software which can record and edit the users is the main content and task of the research topic. The research project "Design and Development of the background based on Video sharing Social system" was designed with the theme of "everyone is a photographer", mainly by providing users with a wide variety of template libraries to choose from. Let the user choose the template according to the needs of his hobby, shoot the video he wants, and edit the video through the rich editing tools, and make beautiful video. And through video sharing software to meet the need to communicate with different friends, which in turn enhance the popularity of the software needs. Video sharing social system background design, using Python as the mainstream language. The Django framework of Python is used to develop, and the design pattern of MVC (Model View Controller) software is adopted, which has strong expansibility. The project uses the B / S (Browser Server) architecture to implement the background design of the system, storing the massive template library, user information and video information taken on the cloud server. In order to facilitate the non-professional personnel to manage the background data, the project has developed the visual background of nutmeg video management. The administrator can upload and update the video template library through the given account number and password, and update the user information. Video file management, all-around guarantee the normal operation of nutmeg video. In the development of nutmeg video project, it mainly involves cloud service storage, cache under Django framework and video popularity. The load balance of cloud server is optimized by DWOLB (dynamic well-organized load balancing) algorithm, which can save power consumption and energy at the same time. The Django framework encapsulates the key word key of the data in the cache, ensures the security of the cached data by re-setting the prefix, and uses the FPPF (Forgot Past Predict Future) algorithm to predict the video popularity, which greatly improves the prediction ability. The processing and implementation of server shared cache data, OAuth2.0 authentication protocol and data object serialization are completed.
