Abstract:

For the capabilities limitations of mobile video system based on embedded, designed the application software on the thread in acquisition side and monitor side, to improve the video processing speed. Designed the mobile video system based on ARM9 S3C2440 hardware platform, and do the research the thread of the application software. Change the single thread to double thread on the collect side, monitoring side is designed with one thread, which coordinated video collection, codecs and player. Experimental results show that the speed of video processing increase effectively, improving two frame per second or so, which is more to meet the needs of mobile video applications with only 400 MHz frequency of the platform.
