Abstract


Digital multimedia technology and Internet technology to enrich people's lives . The media player is a direct way of user experience music , video and other multimedia information . The audio and video media files in the media player , the encoded compressed after decoded for playback. In recent years , the media player in the process of gradually matured become increasingly commercialized . This article is based on DirectShow technology , design a fully functional , the structure is simple and scalable audio and video player . In this paper work , including the following : (1) DirectShow basics . This article first in-depth study on DirectShow technology architecture , the basic knowledge of the main components and filter chart (Filter Graph) , and then introduce a the DirectShow common interface . '(2) the development process of the player . First player to build and utilize corresponding codec Filter , to complete the play link , the basic format file playback ; then focuses on the player control interface , detailed realization of the principle and the player to play link the process of the realization of the basic functions of the player ; Finally, given the development method of the Filter and the Filter design and development to achieve the basic functions of shots . This design of the player has strong scalability , the corresponding function can be extended by increasing the filter , and the player supports a variety of audio and video formats .
