【摘要】：近年来,随着智能手机的普及,智能终端超越PC(Personal Computer)机成为主流,人们社会正式进入了移动互联时代。随着移动互联时代的到来,一个个性化推荐的时代在人们面前展开,每个普通人都想记录下生活的精彩瞬间并同时与亲朋好友分享。但是目前市场上的视频拍摄软件,功能却非常的单一,因此在此背景下,一种能够记录并编辑出用户所要的视频软件的研发正是研究课题的主要内容和任务。研究课题“基于视频分享社交系统后台的设计与研发”所涉及的项目是以“人人都是摄影师”为主题思想而设计的,主要是通过为用户提供丰富各式各样的模板库的选择,让用户自己根据爱好需求通过该软件选择所需的模板,拍摄出自己想要的视频,并通过该软件丰富的编辑工具,对所拍摄的视频进行编辑,制作出优美的视频,并通过视频分享软件满足与不同好友用户进行交流的需求,从而反过来提升该软件的知名度的需求。视频分享社交系统的后台设计,采用的是以Python作为主流语言。应用Python的Django框架进行开发,采用MVC(Model View Controller)软件设计模式,具有较强的扩展性。该项目采用B/S(Browser Server)架构来实现了系统后台设计,将海量模板库、用户信息和拍摄的视频信息存储在云服务器上。为了方便非专业人员对后台数据资料进行管理,课题研究项目又开发了可视化豆蔻视频管理后台,管理员通过给定账号和密码,可对视频模板库进行上传和更新,对用户资料、视频文件进行管理,全方位保障豆蔻视频的正常运行。在对豆蔻视频项目的开发过程中,主要涉及了云服务存储、Django框架下缓存、视频流行度进行探索。通过DWOLB(dynamic well-organized load balancing)算法对云服务器负载均衡进行优化,在保证性能同时,节省耗电量,节约能源;Django框架对缓存中数据的关键字key进行封装,通过重新设置前缀,确保缓存数据的安全性;利用FPPF(Forgot Past Predict Future)算法对视频流行度进行预测,大大提高了预测能力。完成了对服务器共享缓存数据、OAuth2.0认证协议、数据对象序列化的处理和实现。
[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.
