摘要 高清视频监控画面范围广同时产生巨大数据使得在网络传输中造成时延,也存在音频数据有限的问题。针对上述问题,文中设计一种基于B/S架构的实时高清音视频监控系统。USB摄像头基于V4L2接口采集图像,基于ALSA声卡驱动采集音频,结合H.265视频编解码技术和FAAC音频编码技术,以RTP协议打包封装H.265视频码流和AAC音频码流经网络同步传输到Web服务器,利用CGI,JavaScrict技术实现多种智能终端登录浏览器显示监控画面。经测试该监控系统画面清晰无抖动,音视频吻合效果明显满足实验要求。 The high-definition video monitoring images have wide application range,but can simultaneously generate huge amount of data,which may cause the problems of network transmission delay and limited audio data. Therefore,a real-time highdefinition audio and video monitoring system based on the B/S architecture is designed in this paper. The USB camera is used to collect images by means of the V4L2 interface and audios by means of the ALSA sound card driver. In combination with the H.265 video encoding and decoding technology and FAAC audio encoding technology,the H.265 video code stream and AAC audio code stream are packaged and encapsulated by using the RTP protocol,and then simultaneously transmitted to the Web server via network. The CGI and JavaScript technology are used to realize various intelligent terminals′ login into browser for monitoring image display. The test results show that the monitoring system can generate clear images without any jitter,and has an obvious audio and video synchronization effect,which can meet the experimental requirements.
