摘要
针对目前网络摄像机外部网络访问困难的问题,在此提出了基于视频流串流转发的解决方案。对现有网络摄像机软件架构进行重新设计。从前端CMOS摄像头获取原始数据影像,前期处理后经MPEG4/H.264压缩格式对视频数据进行编码,通过live555流化后经进行网络传输。利用live555构成rtsp流服务器,VLC作为流媒体转发节点,通过串流转发实现流媒体主动发送功能,解决了外网访问内网设备的难题。
To overcome the difficulty existing in external network access of network cameras, a new Solution based on the video stream forwarding is put forward. The available IP camera software architecture was redesigned. The raw data images are got from a CMOS camera at front end, the video data is encoded by the MPEG4/H. 264 compression format after image processing in earlier stage, and then transmitted by live555 software through network. A RTSP streaming server is made up by means of live555. The software VLC works as a trarismitting node of streaming media to send the stream data initiatively by the VLC forwarding function and realize the function that the WAN equipments visit the LAN equipments.
