嵌入式MPEG-4视频流媒体服务器设计
Design of an Embedded MPEG-4 System Video Stream Server
【摘要】 利用GPI(通用公共授权)的开源Linux代码,介绍了嵌入式MPEG-4视频服务器的设计和研制,阐述了在嵌入式Linux平台上设计、优化设备驱动程序和视频流媒体服务器的策略。本设计采用GO7007SB作为硬件压缩芯片,使用AT91RM9200芯片作为主要控制芯片,实现了带100 MHz以太网接口的高性能网络摄像机。在约1 Mbit/s的传输率下,可以达到CCIR-601格式的视频信号的实时压缩和传输能力。
【Abstract】 Using the open source Linux code under General Public License(GPL),an embedded MPEG-4 video server is designed and developed.Some methods implementing and optimizing the device driver and stream server on embedded Linux platform are introduced.In the design,the GO7007SB as compression chip and the AT91RM9200 as main control chip are adopted.A new high performance network camera with 100MHz Ethernet interface is implemented and it has realized real-time abilities of compressing and transmitting CCIR-601 video signal at about 1 Mbit/s.
