| Abstract: | In this paper,according to the characteristics of TI's TMS320DM6437 platform,a video system is implemented based on an open source H.264 encoder X264.TI's DSP/BIOS system is used to speed up the development process.This multithread video system implements video capture,video encode,transmission,video decode and video display.Experimental results show that,after making full use of DSP/BIOS system and setting up the thread schedule,the entire system can run at a high speed and the development time can be redu... |
