找不到定义fl.video.FLVPlayback

Question

我被难住了。我有两个正在编辑的flash文件。

文件A在stage上有一个MovieClip，它链接到我导入fl.video.FLVPlayback的类。文件B也尝试导入fl.video.FLVPlayback。

文件B抛出一个编译时错误，指出它无法找到fl.video.FLVPlayback的定义。我注意到我的FlashDevelop也没有为这一行提供语法突出显示。

这两个文件都导出为相同版本的FlashPlayer (10)。这两个文件都是在同一个平台上创作的，相同的软件(CS4).I没有干扰任何发布设置，除了文件B与文档类相关联之外。

有趣的是，文件A最终将被加载到文件B中，加载到文件B的上下文中。

怎么回事？我甚至不知道从哪里开始找。

提前谢谢。

Answer 1

如果您没有使用FLVPlayback组件(从组件库拖到舞台上)，则Flash无法访问开箱即用的fl包以进行发布。

您必须在您的类路径中包含组件源文件夹或.swc (源文件夹将位于as3发布设置的“源路径”选项卡中，.swc位于“库路径”选项卡中)，以便您的类能够工作。

源文件夹为：C:\Program Files (x86)\Adobe\Adobe Flash CS4\Common\Configuration\Component source \ActionScript3.0\FLVPlayback

Adobe位于以下目录中:Adobe C：\Program Files (X86)\\Adobe Flash CS4\Common\Configuration\Components\Video

swc可能更容易包含，因为如果您愿意，可以直接将.swc复制并粘贴到项目文件夹中。

基于Sapptime的回答，我想补充说，您可以在Publish Settings下创建不同的配置文件。

因此，您可以通过导入.swc文件来创建包含FLVPlayback组件的概要文件，并在需要使用FLVPlayer时使用该概要文件。将大约100 KB添加到项目中。

这样，您的库中或舞台上就不需要FLVPlayback组件了。相反，您可以像导入项目中的任何其它类一样导入FLVPlayback类，并在actionscript代码中创建FLVPlayback的实例。

//import:
import fl.video.FLVPlayback;

//Instantiate:
private var player:FLVPlayback = new FLVPlayback();

我为一个项目添加了一个Videoplayer.as类(因为我找不到附加它的方法)，并快速地剥离了它以获得一些额外的内容，但它应该可以工作:)随意使用它，修改它或获得一些灵感。

将Videoplayer.as放在项目的src文件夹中并创建一个新的实例。使用setter来控制它。

//Instantiate
var MyPLayer:Videoplayer = new Videoplayer();

//Use setters
MyPLayer.SetVideopath = path to flv file;
MyPLayer.SetVideoAutoplay = true; // or false
//... and so on

// add to displaylist
this.addChild(MyPlayer);

// Load video
MyPlayer.Load();

// start playing
MyPlayer.Play();

这是Videoplayer类。

package  {
import fl.video.*;
import flash.events.*;
import flash.display.Sprite;
import flash.display.Shape;

public class Videoplayer extends Sprite {

    // VIDEO
    private var player:FLVPlayback = new FLVPlayback();

Answer 3

您需要确保库中存在FLVPlayback组件，并为ActionScript导出该组件(这应该是默认设置)。

要将其添加到库中，只需打开Components面板(Window -> Components)，展开名为Video的组，然后在库中拖动FLVPlayback即可。不需要把它放在舞台上。

默认情况下应将其导出为"fl.video.FLVPlayback".
