Abstract
Multimedia technology is currently the fastest growing area of information technology, the most active technology, a new generation of electronic technology development petition focus Duo Meiti technology with high-speed information Wang, enables puter's working and sharing of information resources, is widely used in Zhuduo industry. Embedded systems are the most promising areas of IT applications, OMAP3530 is TI introduced a new generation of mobile applications processor, which has a very good multimedia capabilities.
This paper describes the platform for the OMAP3530 multimedia player design, were embedded Linux software development environment under Linux build and the current best media player Mplayer the transplants were introduced in detail. The design will be under the X86 platform, Mplayer ported to OMAP3530 platform, realizing more format video files playback. The article finally made a ultimate viable option according to the testing and contrast with the various performance indicators of Mplayer over the embedded platform.
Keywords: Embedded; Mplayer; OMAP3530; Software transplant
