VideoError: 1008: VideoPlayer.iNCManagerClass has not been set or its value is invalid

用FDT 寫純as3.0檔案，當中用到了VideoPlayer

要想引入這個庫只需要在flash中引用 FLVPlayback,產生swc檔案，然後引用FDT中

但是遇到了：

Exception fault: VideoError: 1008: VideoPlayer.iNCManagerClass has not been set or its value is invalid: fl.video.NCManager
    at fl.video::VideoPlayer/http://www.adobe.com/2007/flash/flvplayback/internal::createINCManager()
    at fl.video::VideoPlayer/http://www.adobe.com/2007/flash/flvplayback/internal::_load()
    at fl.video::VideoPlayer/play()

查了一些材料，

解決辦法是：

加入行

  fl.video.VideoPlayer.iNCManagerClass = fl.video.NCManager;
