我试图研究和阅读很多关于这个问题的文章
我有一些红色，但讨论似乎在没有解决方案的情况下结束
所以问题是我无法在我的CI应用程序上显示相机，但是当我只是复制确切的代码并将其粘贴到我的localhost而不使用任何框架工作时它会起作用。
这是我的CI代码
<script type="text/javascript" src="<?=base_url('assets/js/cam/webcam.js')?>"></script>
<script language="JavaScript">
document.write( webcam.get_html(440, 240) );
</script>
<form>
<br />
<input type=button value="Configure settings" onClick="webcam.configure()" class="shiva">
<input type=button value="snap" onClick="take_snapshot()" class="shiva">
</form>
<script type="text/javascript">
webcam.set_api_url( "<?=base_url('assets/js/cam/handleimage.php')?>");
webcam.set_quality( 90 ); // JPEG quality (1 - 100)
webcam.set_shutter_sound( true, "<?=base_url('assets/js/cam/shutter.mp3')?>" ); // play shutter click sound
webcam.set_hook( 'onComplete', 'my_completion_handler' );
function take_snapshot(){
// take snapshot and upload to server
document.getElementById('img').innerHTML = '<h1>Uploading...</h1>';
webcam.snap();
}
function my_completion_handler(msg) {
// extract URL out of PHP output
if (msg.match(/(http\:\/\/\S+)/)) {
// show JPEG image in page
document.getElementById('img').innerHTML ='<h3>Upload Successfuly done</h3>'+msg;
document.getElementById('img').innerHTML ="<img src="+msg+" class=\"img\">";
// reset camera for another shot
webcam.reset();
}
else {alert("Error occured we are trying to fix now: " + msg); }
}
</script>
我使用了这个演示包，如果我将它解压缩到localhost，它的工作正常。 https://app.box.com/s/nkhgrj73fvutaj6dfspf
但是当我尝试将它集成到CI时，相机窗口显示为空白。当我尝试使用网络摄像头js功能，如webcam.configure（）..它说电影尚未加载

只需复制粘贴即可在codeigniter上实现。错误It says the Movie is not loaded yet背后的原因webcam.swf未加载。实际上flash文件是网络摄像头功能背后的重要内容。
创建新控制器application\controllers\camera.php
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Camera extends CI_Controller {
public function index(){
$this->load->helper('url');
$this->load->view("camera");
}
public function saveImage(){
/*write your own code to save to your database*/
$newname = "some_name.png";
file_put_contents( $newname, file_get_contents('php://input') );
}
}
?>
创建新视图application\views\camera.php

现在将webcam.js,shutter.mp3,webcam.swf复制到assets/js/cam。在webcam.js
第27行：swf_url：＆＃39; webcam.swf＆＃39;
第28行：shutter_url：＆＃39; shutter.mp3＆＃39;
更改为
第27行：swf_url：＆＃39; assets / js / cam / webcam.swf＆＃39;
第28行：shutter_url：＆＃39; assets / js / cam / shutter.mp3＆＃39;

来自Tintu先生答案增加了一些修订
只需复制粘贴即可在codeigniter上实现。错误背后的原因它说电影没有加载但是没有加载webcam.swf。实际上，Flash文件是网络摄像头功能背后的重要内容。

现在将webcam.js，shutter.mp3，webcam.swf复制到assets / js / cam。在webcam.js中进行2次小改动
line number 27 : swf_url: 'webcam.swf'
line number 28 : shutter_url: 'shutter.mp3'
更改为
line number 27 : swf_url: '../assets/js/cam/webcam.swf'
line number 28 : shutter_url: '../assets/js/cam/shutter.mp3'
注意：这个网址很重要并且会有所不同..根据我的经验，最好通过谷歌浏览器检查.swf url exstince而不是firefox ..添加'../'上传一个文件夹让你进入root app文件夹访问资产文件夹
干杯
