The Research And Implementation Of Streaming Media Player Based On DSP

With the rapid development of multimedia technology and computer networks and communication technology, streaming media applications is playing a more and more important role in internet applications. Network multimedia applications and video surveillance are developing rapidly. Embedded streaming media terminals have feature of low cost, low power consumption, it has a wide range of applications.In this paper, a streaming media player is designed. TI Davinci Technology based OMAP3530 processor is used as the hardware platform. An embedded Linux system is ported on the player platform. Gstreamer elements and a Gstreamer application are developed in the open source multimedia framework Gstreamer. The server and the client communicates using UDP protocol and muticast. The MPEG-4 codec is used as the video codec of the system. By unpacking and recombinanting the packed MPEG-4 encoded video stream, packet loss and frame loss that are on the unreliable protocol are well solved. For the request of mobility, a wireless module is added to the terminal, so the client system is not limited to the wired network, this makes the terminal more useful .The test results show that the player can play streaming video in real time, and multiple clients can access to the streaming media system at any time. It fulfills the design specification.
