T264 Decode Filter Design Based On Derectshow And Other Relative Design

As the rapid development of information technology, computer network technology and communications technology, video surveillance is also moving gradually from the traditional security surveillance to the network digital video surveillance..Networked digital control system is usually designed as the C/S structure, therefore the design of DirectShow-based network video surveillance client is very necessary. This paper focuses on the T264-based DirectShow decoder filter design and other design work in the client.As the real-time video communications demand highly for the network bandwidth and transmission delay,H.264 is the next most efficient generation of video compression coding standard, ensuring a higher coding efficiency while providing a good quality assurance. DirectShow is a COM-based package recommended by Microsoft for processing of streaming media. One advantage of DirectShow is that it can improve system versatility and scalability.This paper reviews the video surveillance system development process and looks to the future development of video surveillance;.According to integrated design of client part, paper emphasis on how to explore our own Filters for decoding H.264 bit stream.Design details of splitter filter and T264 decoder filter is provided in chapter 3.Net Receiver Filter is a source filter implementing to receive data from the Internet。The key point to realize Net Receiver Filter is to design data reception loop and Sample padding and delivery.Finally, the last chapter makes a brief description of software architecture of the client and the functional partitions based on C/S structure.The other related designing is specified, including VC workspace designing, Socket programming for data reception interface,Filter Graph building, event notification between Filter Graph and the application.
