Based On FFMPEG Video Conversion System

The subject project is an enterprise application, from the applications of Internet video distribution. In recent years, digital video industry has been rapid development, the spread of video and video-sharing also formed an industry, gradually formed a huge cake in a market. But followed by technical problems and video quality problems became a major obstacle to development. Establish a set of video technology to lower the threshold, automatically converting videos web platform has become an urgent need to spread. Against such a background, the practical meaning of study on Video Converter Application is very important.The project set up on teamwork theory, the use of computer supported cooperative model to provide the service environment of the system, the ones that stood in computer had already to work (CSCW) in coordination had a history of more than ten years, with the network technology, especially the development of internet, how is it to support people to work in coordination with under the environment of network computer, improve colony's working efficiency, has already become a new research and application. It suit colony of research it is main in this text in coordination with, mutual CSCW of information apply scientific research of, the online scientific research of the structure improves working efficiency in coordination with the platform.The concept of CSCW at first of this text has been explained, to activity theory, coordinate theory, task management device and face target activity support model, etc. Common CSCW cooperate theory model analyses, use UML to set up their corresponding model, and has classified it according to the characteristic of CSCW, then introduced the application of CSCW, has carried on the detailed argumentation to the key technology of CSCW, the ones that studied CSCW system offered theoretical foundation and basis for serving environment research in coordination in scientific research to the Video Conversion System model finally.Then thesis introduced the server-side architecture principle of based on FFMPEG video conversion system, combine the current status of the application of video conversion, we using cooperative work CSCW theory set up the video conversion system, and get a full range of research to the system, Put forward for an integrated framework of server structure. This structure can increase the system compatibility; substantially improve the efficiency of videos conversion. Achieve in order to handle many user requests the task, in this paper, in-depth exploration into how to deal with a number of server requests client approach, methods such as single process\multi-thread, analyzed the various methods of advantages and disadvantages and application of occasions, then give an implementation program of FFMPEG technology-based infrastructure platform.Abroad progress of respect carry on research, through right to work analysis and discussionof the demand, tool of current situation in coordination in coordination both at home and abroad, and analyses and compare to some existing in coordination with the tool, the system structure of the tool that put forward three stories of the work pattern of adopting B/S structure and work in coordination. Use the module on the basis of Microsoft .net, C# technical design and realize video capture module, data processing module, exception handling module that have realized under B/S mode. Finally, make the prospect that is summarized and working to the work of this text further.
