从使用Adobe AIR本地文件播放视频

问题描述

我想打使用Adobe AIR的，并从本地文件系统中读取视频，以及显示图像和其他可能的Flash内容。我一直在寻找的API，我还没有能够连接点。

I'd like to play videos, as well as display images and possibly other flash content using adobe air, and reading from the local file system. I've been searching APIs and I have not yet been able to connect the dots.

我知道 flash.filesystem.File将和 flash.filesystem.FileStream 并曾试验加载和读取文件。我相信我可以加载图像这种方式，但还没有尝试过。

I know of flash.filesystem.File and flash.filesystem.FileStream and have experimented with loading and reading files. I believe I can load images this way but haven't tried.

至于视频：

mx.controls.VideoDisplay当 - 似乎已经接受了一个文件：// URI源，但我不能让它的工作。

mx.controls.VideoDisplay- seems to accept a file:// URI for source, but I can't get it to work.

flash.media.Video - 接受的NetStream或可以直接从视频输入加载视频，似乎无法找到一个方法来引用本地文件

flash.media.Video- accepts a NetStream or can load video directly from a video input, can't seem to find a way to reference a local file

谁能帮助我在这里？我特别要加载，并直接播放视频关闭本地磁盘，而不是从Web服务器或流媒体文件服务器......假设没有网络连接。

Can anyone help me out here? I specifically want to load and play video directly off the local disk, not from a web server or a streaming file server... assume no network connectivity.

略相关的问题：加载从本地文件系统中的视频... （但我的问题不涉及网络浏览器）

Slightly related question: Loading a video from the local file system… (but my question does not involve a web browser)

推荐答案

在脑海中使用我的要求是计划中的使用。我一直在寻找一种方式来直接使用ActionScript做到这一点。

The use I have in mind is required to be programmatic in usage. I was looking for a way to do this directly with ActionScript.

我终于迷迷糊糊到我希望的......使用NetStream对象的解决方案，但（非直觉），你可以用它来访问本地文件，以及：

I finally stumbled onto the solution I was hoping for... using a NetStream object, but (non-intuitively) you can use this to access local files as well:

private function playVideo():void {
  var nc:NetConnection = new NetConnection();
  nc.connect(null);

  var ns:NetStream = new NetStream(nc);

  # onMetaData listener is required otherwise you get a ReferenceError
  var client:Object = new Object();
  client.onMetaData = function(metadata:Object):void {
    trace(metadata.duration);
  }
  ns.client = client;

  var v:Video = new Video();
  v.attachNetStream(ns);
  stage.addChild(v);

  var f:File = new File("/tmp/test.flv");
  ns.play(f.url);
}
