# rtsp-downloader
用 ffmpeg 来给指定的 rtsp/http 视频流录像，存储到本地。基于 Docker 安装，用在 openwrt 里。
### Docker 构建和部署
准备工作，构建和安装 docker 包，先把本机的 Docker 启动：
- 本地打包：`npm run docker:build`
- 给arm的软路由打包：`npm run docker:build_arm`
- 本地调试启动：`npm run start`
- 导出tar包到本地：`docker save -o rtsp-downloader.tar rtsp-downloader`
- openwrt 安装包：`docker load < rtsp-downloader.tar`
把 tar 拷贝到 openwrt 里，启动容器：
```
docker run --init -d --restart=unless-stopped -v /mnt/usb7-2/Camera:/app/videos -v /root/Configs/rtsp-downloader:/app/config -e TZ=Asia/Shanghai --publish 3000:3000 --name rtsp-downloader rtsp-downloader /app/bin/recorder.js
```
Mount 两个目录：
- 配置目录：映射到`/app/config`
- 录像目录：映射到`/app/videos`
配置目录中存放一个 `config.json` 文件：
```
{
"url": "http://47.51.131.147/-wvhttp-01-/GetOneShot?image_size=1280x720&frame_count=1000000000",
"timeLimit": 15,
"folderSizeLimit" : 5,
"name": "cam1",
}
```
- url: 视频流地址
- timeLimit: 视频文件时长，默认 15 分钟
- folderSizeLimit: 文件夹大小限制，默认 5 GB
- name: 摄像头名称，默认 cam1
> openwrt 启动容器报错：“[FATAL tini (7)] exec /app/bin.js failed: No such file or directory”
>
> 这个是 openwrt 的 bug，别用他的后台 GUI 导入镜像文件，要手动拷贝进 openwrt 然后手动执行`docker load ...`命令
ps:

### 源码开发和调试
引用方法：
```
npm i --save rtsp-downloader
```
仓库源码调试方法：
代码调用方式参照：`../example/home.js` 或者执行 `npm run dev`
使用方式：
```js
const Recorder = require('rtsp-downloader').Recorder
const FileHandler = require('rtsp-downloader').FileHandler;
```
例子：
```js
const Recorder = require('rtsp-downloader').Recorder
var rec = new Recorder({
url: 'rtsp://192.168.1.12:8554/unicast',
timeLimit: 60, // time in seconds for each segmented video file
folder: '/Users/tmp/videos',
folderSizeLimit : 10, // 10 G
name: 'cam1',
})
// Starts Recording
rec.startRecording();
```
记录音频的例子：
```js
const Recorder = require('rtsp-downloader').Recorder
var rec = new Recorder({
url: 'rtsp://192.168.1.12:8554/unicast',
timeLimit: 60, // time in seconds for each segmented video file
folder: '/Users/tmp/videos',
name: 'cam1',
type: 'audio',
})
rec.startRecording();
// stop recording
setTimeout(() => {
console.log('Stopping Recording')
rec.stopRecording()
rec = null
}, 125000)
```
截图的例子：
```js
const Recorder = require('rtsp-downloader').Recorder
var rec = new Recorder({
url: 'rtsp://192.168.1.12:8554/unicast',
folder: '/Users/tmp/imgs/',
name: 'cam1',
type: 'image',
})
rec.captureImage(() => {
console.log('Image Captured')
})
```
管理资源目录：
```js
const FileHandler = require('rtsp-downloader').FileHandler;
const fh = new FileHandler()
// RETURNS DIRECTORY SIZE
fh.getDirectorySize('/Users/tmp/videos/', (err, value) => {
if (err) {
console.log('Error Occured')
console.log(err)
return true
}
console.log('Folder Size is ' + value)
})
// REMOVES ALL MEDIA FILES
fh.removeDirectory('/Users/tmp/videos/*', () => {
console.log('Done')re
});
```
自定义目录格式
```js
const Recorder = require('rtsp-downloader').Recorder
var rec = new Recorder({
url: 'rtsp://192.168.1.12:8554/unicast',
timeLimit: 60, // time in seconds for each segmented video file
folder: '/Users/tmp/videos',
name: 'cam1',
directoryPathFormat: 'MMM-D-YYYY',
fileNameFormat: 'M-D-h-mm-ss',
});
// Default directoryPathFormat : MMM-Do-YY
// Default fileNameFormat : YYYY-M-D-h-mm-ss
// Refer to https://momentjscom.readthedocs.io/en/latest/moment/04-displaying/01-format/
// for custom formats.
// Starts Recording
rec.startRecording();
```
判断是否正在录像：
```js
const Recorder = require('rtsp-downloader').Recorder
var rec = new Recorder({...});
// check if recoder is running?
rec.isRecoding(); // return true or false
```
