The Research Of Multi-Path Stereoscopic Video Real-Time Presentation Based On DirectShow Technology

With the development of science and technology, people demand visual deepening and the traditional media can not meet the needs. So stereoscopic video emerged. As a new digital media, three-dimensional video is called the fourth-generation media format after the audio, image, video. Compared with traditional media, the advantage of stereo video is giving immersive feel, with strong visual impact, and creating more intuitive for the audience experience the real scene. According to the number of stereo video view, It can be divided into two-and multi-perspective viewpoint. Because of great amount of data, how to effectively deal with real-time data in preparation for the synthesis and presentation are the problems which must be faced.Microsoft DirectX, a Windows-based platform providing programming interface, can efficiently complete real-time animation rendering, interactive music and environment sound effects, multimedia data processing and other general API is difficult to accomplish. As a member of the family DirectX, DirectShow is the media in order to meet the new challenges facing the design of development tools, its advantage is not limited to dealing with complex data formats for multimedia streaming and large amounts of data. More importantly, using it we considered neither the bottom of the abstract work and the overall application framework, nor too much about complex data synchronization problems. developing multimedia applications becomes quick and easy freeing developers.Based on DirectShow technology,developing the source filter and transform filters were realized from the hard drive to read files and eight-way video received from the network and processed by a series of synthetic and display .the processing is format conversion, image scaling and blending so. Large amount of data makes real-time become the focus of the design. So as much as possible to improve the efficiency of code, this code is optimized, greatly reducing the processing time. After debugging, the results smooth, clear, reaches the desired effect.
