Node-Media-Server v4

If you like this project you can support me.

Introduction

Node-Media-Server is a high-performance/low-latency/open-source Live Streaming Server developed based on Nodejs.
v4 is design to implement enhanced RTMP FLV v1 support for native HEVC, VP9, AV1.
v4 is no longer compatible with the cn_cdn extension id flv_265 standard.
v4 is no longer compatible with flashplayer's rtmp protocol.
v4 is incompatible with v2. Do not upgrade across major versions.

Static file services

Node-Media-Server can provide static file services for a directory.

"static": {
    "router": "/",
    "root": "./html"
}

Record to flv file

Node-Media-Server can record live streams as FLV files.
When the static file server is enabled and recordings are saved in its directory.
It can provide video-on-demand services.

"record": {
    "path": "./html/record"
}

http://server_ip:8000/record/live/stream/unix_time.flv
or
https://server_ip:8443/record/live/stream/unix_time.flv

REST API System (New in v4.2.0)

Node-Media-Server v4.2.0 introduces a comprehensive REST API system for server management and monitoring.

Authentication

The API system uses JWT-based authentication with the following endpoints:

Login

POST /api/v1/login
Content-Type: application/json

{
  "username": "your_username",
  "password": "your_password"
}

Response:

{
  "success": true,
  "data": {
    "token": "your_jwt_token",
    "expiresIn": "24h"
  },
  "message": "Login successful"
}

Using the API

Include the JWT token in your requests:

Authorization: Bearer your_jwt_token

API Endpoints

Health Check

GET /api/v1/health

Returns server health status, including CPU usage, memory consumption, and uptime.

Server Information

GET /api/v1/info

Returns server configuration, version information, and system details.

Stream Management

GET /api/v1/streams

List all active streams with detailed information including codecs, bitrate, and connected clients.

Session Management

GET /api/v1/sessions

Monitor all connected clients (publishers and players) with session details.

DELETE /api/v1/sessions/{sessionId}

Terminate a specific session by ID. This will disconnect the associated client and stop their stream or playback.

Response:

{
  "success": true,
  "data": {
    "id": "sessionId",
  }
  "message": "Session deleted successfully",
}

Server Statistics

GET /api/v1/stats

Real-time server performance metrics including:

• CPU usage percentage
• Memory consumption (RSS, heap total, heap used)
• Process uptime
• Active stream count
• Connected client count

Configuration

The API system is configured through the bin/config.json file:

"auth": {
    "play": false,
    "publish": false,
    "secret": "nodemedia2017privatekey",
    "jwt": {
        "expiresIn": "24h",
        "refreshExpiresIn": "7d",
        "algorithm": "HS256",
        "users": [
            {
                "username": "admin",
                "password": "admin123"
            }
        ]
    }
},

Security Features

Password Hashing

Passwords are securely stored using MD5 hashing. To generate a hashed password:

const crypto = require('crypto');
const hashedPassword = crypto.createHash('md5').update('your_password').digest('hex');

JWT Configuration

• Configurable secret key for token signing
• Support for different algorithms (HS256, HS384, HS512)
• Configurable token expiration times
• Refresh token support for extended sessions

Example Usage

Using curl

# Login
curl -X POST http://localhost:8001/api/v1/login \
  -H "Content-Type: application/json" \
  -d '{"username":"admin","password": md5("password")}'

# Get server stats
curl -X GET http://localhost:8001/api/v1/stats \
  -H "Authorization: Bearer your_jwt_token"

# Get active streams
curl -X GET http://localhost:8001/api/v1/streams \
  -H "Authorization: Bearer your_jwt_token"

# Get all sessions
curl -X GET http://localhost:8001/api/v1/sessions \
  -H "Authorization: Bearer your_jwt_token"

# Delete a specific session
curl -X DELETE http://localhost:8001/api/v1/sessions/abc123-def456-ghi789 \
  -H "Authorization: Bearer your_jwt_token"

Using JavaScript

// Login and get streams
const response = await fetch('http://localhost:8001/api/v1/login', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ username: 'admin', password: md5('password') })
});

const { token } = await response.json();

// Get streams
const streamsResponse = await fetch('http://localhost:8001/api/v1/streams', {
  headers: { 'Authorization': `Bearer ${token}` }
});

const streams = await streamsResponse.json();
console.log('Active streams:', streams);

// Get all sessions
const sessionsResponse = await fetch('http://localhost:8001/api/v1/sessions', {
  headers: { 'Authorization': `Bearer ${token}` }
});

const sessions = await sessionsResponse.json();
console.log('Active sessions:', sessions);

// Delete a specific session
if (sessions.length > 0) {
  const sessionIdToDelete = sessions[0].id; // Get first session ID
  const deleteResponse = await fetch(`http://localhost:8001/api/v1/sessions/${sessionIdToDelete}`, {
    method: 'DELETE',
    headers: { 'Authorization': `Bearer ${token}` }
  });

  const deleteResult = await deleteResponse.json();
  console.log('Session deletion result:', deleteResult);
}
