Getting "Not allowed to load local resource" error while trying to attach a MediaSource object as the source of a HTML5 video tag
提问by Mathew
I am trying to get thisexample to work. It works fine when I click the link. But when I try to download the HTML file on my local machine and try the same, it is throwing this error.
我正在努力让这个例子发挥作用。当我点击链接时它工作正常。但是，当我尝试在本地计算机上下载 HTML 文件并尝试相同操作时，它会抛出此错误。
Not allowed to load local resource: blob:null/6771f68d-c4b8-49a1-8352-f2c277ddfbd4
不允许加载本地资源：blob:null/6771f68d-c4b8-49a1-8352-f2c277ddfbd4
The line of code that seems to be causing the issue is this,
似乎导致问题的代码行是这样的，
video.src = window.URL.createObjectURL(mediaSource);
video.src = window.URL.createObjectURL(mediaSource);
What this line of code is doing is basically trying to set the source of the video tag media element to the MediaSource object. I have tried various permutations without much luck.
这行代码所做的基本上是尝试将视频标签媒体元素的来源设置为 MediaSource 对象。我尝试了各种排列，但运气不佳。
I am using Chrome Version 28.0.1500.72 m, which is the latest stable release.
我使用的是 Chrome 版本 28.0.1500.72 m，这是最新的稳定版本。
I would appreciate any pointers.
我将不胜感激任何指针。

As @dandavis has said, "run it from http: not file".
正如@dandavis 所说，“从 http: not file 运行它”。
I'm posting this as an answer for the sake of organization.
为了组织起见，我将此作为答案发布。
For starters: Running you project from http means having a http server (such as apache or a simple node http-server) and running your project via http://localhost.
对于初学者：从 http 运行您的项目意味着拥有一个 http 服务器（例如 apache 或一个简单的节点http-server）并通过http://localhost运行您的项目。

Install http-serverglobally using npm command(provided you have installed Node.jsin your system beforehand). Navigate to your file folder in CMD and type http-server. Your app should run in localhost:8080.
使用 npm 命令全局安装http-server（前提是您事先在系统中安装了Node.js）。导航到 CMD 中的文件夹并键入http-server。您的应用程序应该在localhost:8080 中运行。
