基于龍芯平臺流媒體服務(wù)的研究
[Abstract]:Longson is a high performance universal CPU developed independently by the Institute of Computing of the Chinese Academy of Sciences, which rewrites the history of "China Core" in China. Jiangsu Zhongke Meng Lan Electronic Technology Co., Ltd. is the industrial base and leading enterprise of Longson. This paper mainly studies the main functions of streaming media server realized in the software and hardware environment of the Godson computer. By analyzing the performance of the Godson platform, optimizing the design of the operating system, optimizing the multimedia instruction, Meet the technical standard of streaming media service under Linux client and windows client platform. In the technical aspect of streaming media service, GStreamer multimedia framework is adopted to realize streaming media service playback openPGM as the transmission framework of streaming media service, and some related performance optimization methods, such as fecal, qos and so on, are added. The server reads the video file and decodes it by decoder, then encoder the video stream into H264 format. The encoded data is sent to the client. After the client receives the data, the data of fec is restored. Decoding shows that 250 terminals can be served simultaneously at the same time. Through this research, we can further enrich the application of Godson platform and explore how to improve the level of education modernization in China by means of independent information technology.
