使用过不少的gb28181服务端工具，绝大部分都是BS结构的，也就是直接在网页上运行，比如easynvr、liveqing等，也有个知名的开源国标项目叫wvp，总体感觉性能都不如意，理论上来说肯定不如直接CS结构的可执行文件来解码显示来的快，毕竟网页运行的东西必须完全依赖浏览器，而浏览器的性能在视频解码这块，比起本地解码来还是差很多的，而且很多时候无法用硬解码，还有就是在国产化大潮下，在国产芯片的电脑上运行网页程序，性能非常的不如意，也许若干年后会好很多。

目前市面上没有看到什么监控系统支持gb28181，支持国标的都是服务器上运行，而且基本上和流媒体服务绑定在一起，也就是国标流拉到后直接推给了流媒体服务，然后给出各种拉流地址让监控系统去拉流显示。这种目前是主流的做法。之前就做过onvif版本的视频监控系统，陆陆续续有不少人问过有没有gb28181版本的，当时看了下协议文档，觉得挺复杂的，就暂时搁置了很多年，最近一年刚好有个大项目需要，索性就直接研究摸透一下，用纯Qt给整出来了，sip服务支持udp和tcp，拉流支持udp/tcp被动/tcp主动。发布后绿色版开箱即用。

支持设备注册、注销、心跳、校时、注册认证、注销认证等。设备上线后可以手动获取设备状态、设备信息、配置信息、预置位信息等。设备上线后自动获取设备通道信息，包括中文通道名称。识别到通道上线离线变化，会重新获取该设备的所有通道信息。支持视频点播，可以分别点播主码流和子码流，内置rtp解包线程，解包后发给视频播放组件解码播放。每个设备每个通道支持点播多个视频，通过ssrc区分，支持共用端口和不同端口收流。支持对某个设备下面所有通道、某个通道、某个通道对应的某个流分别关闭。支持录像文件查询和回放，回放控制支持暂停播放、继续播放、倍速播放、切换播放进度。支持录像文件下载，支持倍速比如8倍速下载，可同时多线程批量下载。回放和下载同时支持IPC和NVR，比如摄像头自带的SD存储卡录像文件回放，NVR上的硬盘录像文件回放。支持云台控制，向上、向下、向左、向右、左上、右上、左下、右下方位移动，镜头放大缩小，光圈放大缩小，镜头聚焦放焦。支持预置位信息的查询、调用、添加、修改、删除等操作。自动目录订阅功能，通道上线下线都有对应的信号通知。内置定时读取通道信息机制，以保证通道信息是最新的，比如有些NVR是不断更新的通道信息。内置订阅警情和位置移动功能，订阅后各种警情事件比如运动目标检测报警、入侵检测报警、徘徊检测报警等自动上报。支持语音对讲功能，可以直接在视频窗体的悬浮条上单击语音对讲按钮，再次单击关闭对讲，对讲期间悬浮条常驻显示。支持设备布防撤防，布防后警情信息会主动上报。国标服务同时支持udp和tcp方式，可选只监听一种或者两种都监听，tcp方式自动处理粘包问题。国标拉流同时支持udp、tcp被动、tcp主动三种方式，每个通道都可以自由选择何种拉流方式。内置拉流端口池，每次拉流从中取出一个，关闭流自动回收端口号，重复利用。收流端口自动纠错，自动跳过被占用的端口，不会出现端口占用导致收流失败的情况。支持三种取流方式自动检测离线重连，检测到离线后，自动重启点播拉流整个流程。录像文件回放，上一个完成后自动切换到下一个继续回放，直到所有回放完成。支持高达8倍速回放。视频播放自适应硬解码，极低资源占用，实时性极好，带悬浮条显示视频流信息，可以直接在悬浮条单击按钮保存录像文件到本地。支持几千路国标消息交互并发，实时视频流支持64路同时显示，可以拓展更多路数。支持阿里云等云服务器，可以分别设置内网监听地址和外网访问地址，一般云服务器上是监听地址用内网，对外访问用外网地址。支持视频分发，也就是推流，视频通道打开后可以自动推流到流媒体服务器，其他需要的地方拉流即可，支持rtsp、rtmp、hls、webrtc等方式拉流。实时预览和录像回放都支持推流，推流支持叠加文字和图片水印以及各种ffmpeg支持的滤镜效果，支持多个水印同时叠加。同时支持gb28181-2011、gb28181-2016、gb28181-2022以及后续可能的所有协议版本。SIP解析和交互采用纯Qt底层代码实现，udp/tcp通信交互，祖传原创代码解析，不依赖任何第三方。代码量少，gb28181交互部分共几千行代码，注释详细，接口友好，使用极其简单，提供非常详细的使用示例。支持海康、大华、宇视、华为、天地伟业等所有国标设备，包括一些没有ssrc的设备。支持所有Qt版本和编译器以及操作系统，包括但不限于win、linux、mac、android、嵌入式linux、树莓派香橙派、国产os等。
