Html5 video标签访问网络摄像机实时监控

网络摄像机+VLC+Node.js+HTML5

网络摄像机大部分都需要安装插件才能看，对于我们这些搞B/S的来说比较麻烦，最近项目中要用到摄像机实时监控，所以查询了些资料。公司采用的大华的东西，将设备全部接入一个局域网中，设置好ip

摄像机1 (

192.168.

8.110)

摄像机2 (

192.168.

8.180)

硬盘录像机NVR (

192.168.

8.108)

百度了一下大华（包含NVR/摄像机）RTSP地址：

rtsp:

//user:

pwd@ip:

port/cam/ realmonitor?channel=1&subtype=0

channel通道，NVR分通道。

subtype码流，0代表主码流（高清1080P），1代表辅码流(704*576(D1)).

直接访问摄像机：

摄像机1:rtsp:

admin@

192.168.

8.110:554/cam/realmonitor?channel=1&subtype=0摄像机2:rtsp:

//admin:

admin@

192.168.

8.110:554/cam/realmonitor?channel=1&subtype=0访问NVR:

摄像机1:rtsp:

//admin:

admin@

192.168.

8.108:554/cam/realmonitor?channel=1&subtype=0摄像机2:rtsp:

//admin:

admin@

192.168.

8.108:554/cam/realmonitor?channel=2&subtype=0Html5

使用vlc命令，在cmd命令下使用（注意下面是一行命令）

vlc -I dummy -vvv

"rtsp:

//admin:

192.168.

8.110:554/cam/realmonitor?channel=1&subtype=1"

--

sout="#transcode{vcodec=theo,vb=800,acodec=vorb,ab=128,channels=2,samplerate =44100}:

http{mux=ogg,dst=:80/cam}" --sout-all --sout-keep

多行0%-100%，基本上就是成功了

HTML5

chrome打开页面就可以看到了

Node.js+HTML5

采用Node.js启动vlc，这里是多个摄像头

app.js

var child_process = require('child_process');

function openCam(rtsp,path){

var server=child_process.spawn("C:

\\Program Files

(x86)\\VideoLAN\\VLC\\vlc.exe",["-I","dummy","-vvv",rtsp,"--

sout=#transcode{vcodec=theo,vb=800,acodec=vorb,ab=128,channels=2,samplerate= 44100}:

http{mux=ogg,dst="+path+"}","--sout-all","--sout-keep"]);

//dummy可以修改为--no-dummy-quiet，隐藏vlc命令窗口

server.on('exit', function (code, signal) {

console.log('service exit');

});}openCam('rtsp:

//admin:

admin@

192.168.

8.108:554/cam/realmonitor?channel=1&subtype=1',':8800/cam');//摄像机110

openCam('rtsp:

//admin:

admin@

192.168.

8.108:554/cam/realmonitor?channel=2&subtype=1',':8801/cam');//摄像机180

目前只能一个摄像机一个端口，端口复用暂时不知道怎么弄。

运行node app，打开html即可

经过测试PC chrome、安卓UC都能打开。
