套件flash.display3D.textures
類別public final class VideoTexture
繼承VideoTexture Inheritance TextureBase Inheritance EventDispatcher Inheritance Object

在 Flash Player 21 之前,若要在 Stage3D 使用視訊,必須使用 Video 物件 (非硬體加速)、將視訊影格複製到 BitmapData 物件,並將資料載入需要大量耗用 CPU 的 GPU。因此,引進了視訊紋理物件。此物件讓您可以在 Stage 3D 內容中使用硬體解碼的視訊。

Flash Player 22 新增了視訊紋理物件,以持續/類似 StageVideo 的方式支援 NetStream 和 Cameras。這類紋理可以在 stage3D 顯示管線當做來源紋理使用。紋理可以在以場景呈現時,當做矩形、RGB、非 MIP 映射紋理使用。著色器會將這些紋理當做 ARGB 紋理 (也就是說,AGAL 著色器不必理會 YUV->RGB 轉換),因此,可以直接使用與靜態影像搭配使用的標準著色器,而不必變更。顯示管線所使用的影像,是使用這個紋理來呈現時的最新影格。視訊影格未出現斷面,但若您多次使用相同紋理,部分實體可能出自不同的時間戳記。

屬性詳細資訊

videoHeight

屬性
videoHeight:int  [唯讀]

語言版本: ActionScript 3.0
執行階段版本: AIR 17.0, Flash Player 18.0

指定視訊串流高度的整數,以像素為單位。

對於即時串流來說,這個值和 Camera 物件的 Camera.height 屬性相同,此 Camera 物件指的是正在捕捉視訊串流的 Camera 物件。針對錄製的視訊檔案,此值為視訊的高度。若是錄製的視訊,則當此值變更時就會傳送 NetStream.Video.DimensionChange 事件。



實作
    public function get videoHeight():int

videoWidth

屬性 
videoWidth:int  [唯讀]

語言版本: ActionScript 3.0
執行階段版本: AIR 17.0, Flash Player 18.0

指定視訊串流寬度的整數,以像素為單位。

對於即時串流來說,這個值和 Camera 物件的 Camera.width 屬性相同,此 Camera 物件指的是正在捕捉視訊串流的 Camera 物件。針對錄製的視訊檔案,此值為視訊的寬度。若是錄製的視訊,則當此值變更時就會傳送 NetStream.Video.DimensionChange 事件。



實作
    public function get videoWidth():int
方法詳細資訊

attachCamera

()方法
public function attachCamera(theCamera:Camera):void

語言版本: ActionScript 3.0
執行階段版本: AIR 17.0, Flash Player 18.0

指定來自攝影機的視訊串流,將顯示在 VideoTexture 物件的紋理內。

使用這個方法可將使用者捕捉的即時視訊附加至 VideoTexture 物件。若要丟棄 VideoTexture 物件的連線,請將 theCamera 參數的值設定為 null。

參數

theCamera:Camera

attachNetStream

()方法 
public function attachNetStream(netStream:NetStream):void

語言版本: ActionScript 3.0
執行階段版本: AIR 17.0, Flash Player 18.0

指定視訊串流,將顯示在 VideoTexture 物件的紋理內。

視訊檔案可以儲存在本機檔案系統或 Flash Media Server 上。如果 netStream 引數的值是 null,則視訊不會在 VideoTexture 物件中播放。

參數

netStream:NetStream

事件詳細資訊

renderState

事件
事件物件類型: flash.events.TextureVideoEvent





[ X ]為什麼顯示英文?
「ActionScript 3.0 參考」的內容是以英文顯示

並非所有「ActionScript 3.0 參考」的內容都翻譯為所有語言。當語言元素未翻譯時,就會以英文顯示。例如,ga.controls.HelpBox 類別並沒有翻譯為任何語言。因此在參考的繁體中文版本中,ga.controls.HelpBox 類別就會以英文顯示。
