用法
git 版本
简单运行方式
npm i
node app.js
多核模式运行
node cluster.js
npm 版本(推荐)
单核模式
mkdir nms
cd nms
npm install node-media-server
const { NodeMediaServer } = require('node-media-server');
const config = {
rtmp: {
port: 1935,
chunk_size: 60000,
gop_cache: true,
ping: 60,
ping_timeout: 30
},
http: {
port: 8000,
allow_origin: '*'
}
};
var nms = new NodeMediaServer(config)
nms.run();
多核模式
mkdir nms
cd nms
npm install node-media-server
const { NodeMediaCluster } = require('node-media-server');
const numCPUs = require('os').cpus().length;
const config = {
rtmp: {
port: 1935,
chunk_size: 60000,
gop_cache: true,
ping: 60,
ping_timeout: 30
},
http: {
port: 8000,
allow_origin: '*'
},
cluster: {
num: numCPUs
}
};
var nmcs = new NodeMediaCluster(config)
nmcs.run();
鉴权验证(更安全)
加密后的 URL 形式:
rtmp://hostname:port/appname/stream?sign=expires-HashValue
http://hostname:port/appname/stream.flv?sign=expires-HashValue
ws://hostname:port/appname/stream.flv?sign=expires-HashValue
1.原始推流或播放地址:
rtmp://192.168.0.10/live/stream
2.配置验证秘钥为: 'nodemedia2017privatekey',同时打开播放和发布的鉴权开关
const config = {
rtmp: {
port: 1935,
chunk_size: 60000,
gop_cache: true,
ping: 60,
ping_timeout: 30
},
http: {
port: 8000,
allow_origin: '*'
},
auth: {
play: true,
publish: true,
secret: 'nodemedia2017privatekey'
}
}
3.请求过期时间为: 2017/8/23 11:25:21 ,则请求过期时间戳为:
1503458721
4.md5计算结合“完整流地址-失效时间-密钥”的字符串:
HashValue = md5("/live/stream-1503458721-nodemedia2017privatekey”)
HashValue = 80c1d1ad2e0c2ab63eebb50eed64201a
5.最终请求地址为
rtmp://192.168.0.10/live/stream?sign=1503458721-80c1d1ad2e0c2ab63eebb50eed64201a
注意:'sign' 关键字不能修改为其他的
RTMP协议传输H.265视频
H.265并没有在Adobe的官方规范里实现,这里使用id 12作为标识,也是国内绝大多数云服务商使用的id号
PC转码推流: ffmpeg-hw-win32

Https/Wss 视频加密传输
生成证书
openssl genrsa -out privatekey.pem 1024
openssl req -new -key privatekey.pem -out certrequest.csr
openssl x509 -req -in certrequest.csr -signkey privatekey.pem -out certificate.pem
配置 https支持
const { NodeMediaServer } = require('node-media-server');
const config = {
rtmp: {
port: 1935,
chunk_size: 60000,
gop_cache: true,
ping: 60,
ping_timeout: 30
},
http: {
port: 8000,
allow_origin: '*'
},
https: {
port: 8443,
key:'./privatekey.pem',
cert:'./certificate.pem',
}
};
var nms = new NodeMediaServer(config)
nms.run();
播放加密传输视频
https://localhost:8443/live/STREAM_NAME.flv
wss://localhost:8443/live/STREAM_NAME.flv
注意:Web浏览器播放自签名的证书需先添加信任才能访问
API
保护API
const config = {
.......
auth: {
api : true,
api_user: 'admin',
api_pass: 'nms2018',
},
......
}
注意:基于Basic auth提供验证,请注意修改密码,默认并未开启。

转 HLS/DASH 直播流
const { NodeMediaServer } = require('node-media-server');
const config = {
rtmp: {
port: 1935,
chunk_size: 60000,
gop_cache: true,
ping: 60,
ping_timeout: 30
},
http: {
port: 8000,
mediaroot: './media',
allow_origin: '*'
},
trans: {
ffmpeg: '/usr/local/bin/ffmpeg',
tasks: [
{
app: 'live',
hls: true,
hlsFlags: '[hls_time=2:hls_list_size=3:hls_flags=delete_segments]',
dash: true,
dashFlags: '[f=dash:window_size=3:extra_window_size=5]'
}
]
}
};
var nms = new NodeMediaServer(config)
nms.run();
直播录制为MP4文件
const { NodeMediaServer } = require('node-media-server');
const config = {
rtmp: {
port: 1935,
chunk_size: 60000,
gop_cache: true,
ping: 60,
ping_timeout: 30
},
http: {
port: 8000,
mediaroot: './media',
allow_origin: '*'
},
trans: {
ffmpeg: '/usr/local/bin/ffmpeg',
tasks: [
{
app: 'vod',
mp4: true,
mp4Flags: '[movflags=faststart]',
}
]
}
};
var nms = new NodeMediaServer(config)
nms.run();
Rtsp/Rtmp 中继
NodeMediaServer 使用ffmpeg实现RTMP/RTSP的中继服务。(我们主要应用这里将rtsp转为rtmp)
静态拉流
静态拉流模式在服务启动时执行,当发生错误时自动重连。可以是一个直播流,也可以是一个本地文件。理论上并不限制是RTSP或RTMP协议
relay: {
ffmpeg: '/usr/local/bin/ffmpeg',
tasks: [
{
app: 'cctv',
mode: 'static',
edge: 'rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov',//rtsp
name: 'BigBuckBunny'
rtsp_transport : 'tcp' //['udp', 'tcp', 'udp_multicast', 'http']
}, {
app: 'iptv',
mode: 'static',
edge: 'rtmp://live.hkstv.hk.lxdns.com/live/hks',//rtmp
name: 'hks'
}, {
app: 'mv',
mode: 'static',
edge: '/Volumes/ExtData/Movies/Dancing.Queen-SD.mp4',//本地文件
name: 'dq'
}
]
}
动态拉流
当本地服务器收到一个播放请求,如果这个流不存在,则从配置的边缘服务器拉取这个流。当没有客户端播放这个流时,自动断开。
relay: {
ffmpeg: '/usr/local/bin/ffmpeg',
tasks: [
{
app: 'live',
mode: 'pull',
edge: 'rtmp://192.168.0.20',
}
]
}
动态推流
当本地服务器收到一个发布请求,自动将这个流推送到边缘服务器。
relay: {
ffmpeg: '/usr/local/bin/ffmpeg',
tasks: [
{
app: 'live',
mode: 'push',
edge: 'rtmp://192.168.0.10',
}
]
}
安装应用流程
安装ffmpeg(版本要求4.0.0以上)
# 进入/usr/local/src目录安装yasm
cd /usr/local/src
wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
tar zxvf yasm-1.3.0.tar.gz
cd yasm-1.3.0/
./configure
make && make install
# 进入/usr/local/src目录安装
cd /usr/local/src
wget https://ffmpeg.org/releases/ffmpeg-4.0.tar.bz2
tar jxvf ffmpeg-4.0.tar.bz2
cd ffmpeg-4.0/
./configure
make && make install
# 查看是否安装成功
cd /usr/local/bin
ll (存在ffmpeg可执行文件)
安装Node-Media-Server
# 克隆工程到本地/usr/local/src目录
cd /usr/local/src
git clone git@github.com:qq1126176532/Node-Media-Server.git
# 开始安装npm
curl --silent --location https://rpm.nodesource.com/setup_10.x | bash -
yum install -y nodejs
npm install -g cnpm --registry=https://registry.npm.taobao.org
# 查看版本确认安装成功
npm -v
#执行安装
cd Node-Media-Server/
npm i
#修改启动脚本(这里以简单工作模式启动为例,多核心集群模式结合中继模式存在一些问题)

引用资料及思考:
感谢如下链接提供文章资源:
前期准备和思考:
- 1.之前没做高这方面的内容,起始渡鸟狗哥都找不到帮助太多的有价值的资料。有时候java搞起来不方便也可以倾向于考虑一下其他脚本语言或者方式的实现。
- 2.ws-socket:此方案最终摒弃原因如下:需要对接外网收费服务,免费服务不稳定,需要定期更新密钥,连接数有限。docker服务地址,官网
- 3.Node-Media-Server方法切合实际需求,可离线内网使用,画面问题需后期持续优化。
- 4.应用Node.js基于Chrome V8 引擎的 JavaScript 运行环境,使用事件驱动、非阻塞式 I/O 的模型轻量高效。
- 5.服务稳定,支持多协议方便后期扩展,服务单一避免冗余和服务带来的代码臃肿,rtsp推流方式多样,提供加密传输机制更加安全。
