browser-media's Introduction

browser-media

browser-media 提供了在浏览器环境下通过摄像头拍照录像API

Demo

浏览器下打开 ./src/index.html 页面。

Usage

在html中直接引入JS文件后使用

<div class="main">
  <div class="videoEl"></div>
</div>

<script src="/dist/main.js"></script>

如果需要滤镜则需要引入 lib/webdsp 文件

const Media = BrowserMedia({
  el: '.videoEl', // video挂载的节点
  type: 'image', // image || video
  autoClose: true, // 是否在拍照/视频后自动关闭media
  audio: false
});
Media.open(); // 初始化

// 拍照 shot
$('.start').click(async () => {
  window.scrollTo({ top: 0 });
  const urlCreator = window.URL || window.webkitURL;
  const imageUrl = urlCreator.createObjectURL(await Media.shot());
  document.querySelector('#image-test').src = imageUrl;
  Media.close(); // 关闭录像状态
});

// 开始录像 startRecord
$('.startRecode').click(async () => {
  Media.setMediaType('video');
  Media.startRecord();
});

/*
* stopRecord 结束录像
* callback function
* videoResuleType string 'file' | ''
* videoResuleType为'file'时返回file对象,否则返回blobSrc
*/
$('.stopRecode').click(async () => {
  Media.stopRecord(blob => {
    document.querySelector('#video-test').src = blob;
  });
});

// 设置滤镜(拍照)
// 'Normal', 'Grayscale', 'Invert', 'Bacteria', 'Sunset', 'Emboss', 'Super Edge', 'Super Edge Inv', 'Gaussian Blur', 'Moss', 'Robbery', 'Brighten', 'Swamp', 'Ghost', 'Good Morning', 'Acid', 'Urple', 'Romance', 'Hippo', 'Longhorn', 'Security', 'Underground', 'Rooster', 'Mist', 'Tingle', 'Kaleidoscope', 'Noise', 'Forest', 'Dewdrops', 'Analog TV', 'Color Destruction', 'Hulk Edge', 'Twisted', 'Clarity', 'Sharpen', 'Uber Sharpen'
Media.setFilter('Invert');

在ES6模块中使用

import 'browser-media'; // 注入全局对象 BrowserMedia
