## Getting Started
### How to use
### Installation Guide
Using Npm
```sh
npm install puppeteer-screen-recorder
```
Using Yarn
```sh
yarn add puppeteer-screen-recorder
```
### API Description
**1. Import the plugin using ES6 or commonjs.**
```javascript
// ES6
import { PuppeteerScreenRecorder } from 'puppeteer-screen-recorder';
// or commonjs
const { PuppeteerScreenRecorder } = require('puppeteer-screen-recorder');
```
**2. Setup the Configuration object.**
```javascript
const Config = {
followNewTab: true,
fps: 25,
ffmpeg_Path: '<path of ffmpeg_path>' || null,
videoFrame: {
width: 1024,
height: 768,
},
videoCrf: 18,
videoCodec: 'libx264',
videoPreset: 'ultrafast',
videoBitrate: 1000,
autopad: {
color: 'black' | '#35A5FF',
},
aspectRatio: '4:3',
};
```
> - **followNewTab** : Boolean value which is indicate whether to follow the tab or not. Default value is true.
> - **fps**: Numeric value which denotes no.of Frames per second in which the video should be recorded. default value is 25.
> - **ffmpeg_Path**: String value pointing to the installation of [FFMPEG](https://ffmpeg.org/). Default is null (Automatically install the FFMPEG and use it).
> - **videoFrame**: An object which is to specify the width and height of the capturing video frame. Default to browser viewport size.
> - **aspectRatio**: Specify the aspect ratio of the video. Default value is `4:3`.
> - **autopad**: Specify whether autopad option is used and its color. Default to autopad deactivation mode.
> - **recordDurationLimit**: Numerical value specify duration (in seconds) to record the video. By default video is recorded till stop method is invoked`. (Note: It's mandatory to invoke Stop() method even if this value is set)
**3. create a new instance of video recording**
```javascript
const recorder = new PuppeteerScreenRecorder(page, Config); // Config is optional
// or
const recorder = new PuppeteerScreenRecorder(page);
```
> - **page**: Puppeteer page object which needs to captured.
> - **config**: Config is an optional object.
> Default value is `{ followNewTab: true, fps: 25, ffmpeg_Path: null }`
**4. Start Video capturing**
**Option 1 - Start video capturing and save as file**
```javascript
const SavePath = './test/demo.mp4';
await recorder.start(savePath);
```
**Option 2 - Start Video capturing using stream**
```javascript
const pipeStream = new PassThrough();
await recorder.startStream(pipeStream);
```
> **pass**: Any writeable stream that will be an output for the stream recorder. Video is recorded and streamed with .mp4 extension.
> **savePath**: string value indicating the directory on where to save the video. The path must also specify the name of the video with extension .mp4 (example - ./test/puppeteer-demo.mp4). Starting from v2, support added for extensions mp4, avi, mov and webm.
**5. Stop the video capturing.**
```javascript
await recorder.stop();
```
### Example
```javascript
const puppeteer = require('puppeteer');
const { PuppeteerScreenRecorder } = require('puppeteer-screen-recorder');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
const recorder = new PuppeteerScreenRecorder(page);
await recorder.start('./report/video/simple.mp4'); // supports extension - mp4, avi, webm and mov
await page.goto('https://example.com');
await page.goto('https://test.com');
await recorder.stop();
await browser.close();
})();
```
## Key Feature
### 1. Follow Page Automatically
Automatically follows pages (multiple pages) which are opened at runtime, which will be part of video capturing. Also support options to disable the default flow.
### 2. No overhead over FF_MPEG library
FFMPEG library's installation and configuration are automatically managed by the library internally. Also offers options to configure with custom library path.
### 3. Native Implementation
This plugin works directly with native [chrome devtool protocol](https://chromedevtools.github.io/devtools-protocol/tot/Page/#method-startScreencast) to capture the video under the wood without any other thirdparty puppeteer plugins for screen capturing.
### 4. Adopted the Chromium principles
Adopted Chromium principles such as Speed, Security, Stability and Simplicity. It also ensures no frames are missed during video capturing and doesn't impact the performance, since its doesn't use any other puppeteer plugin internally.
### 5. Supports multiple video format and stream
Supports multiple video format like AVI, MP4, MOV and WEBM. Enable support for writable or duplex stream for process the output streaming .
