| Inheritance | VideoTexture  TextureBase EventDispatcher Object |
For Flash Player 22, video texture objects were added to support NetStream and Cameras in a manner consistent/ similar to StageVideo. Such textures can be used as source textures in the stage3D rendering pipeline. The textures can be used as rectangular, RGB, no mipmap textures in the rendering of a scene. They are treated as ARGB texture by the shaders (that is, the AGAL shaders do not have to bother about YUV->RGB conversion) and so the standard shaders with static images can be used without change. The image used by the rendering pipeline is the latest up-to-date frame at the time the rendering occurs using this texture. There is no tearing in a video frame, however if the same texture is used several times, some of the instances may be from different timestamps.

videoHeight | property |
videoHeight:int [read-only] | Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 17.0, Flash Player 18.0 |
An integer specifying the height of the video stream, in pixels.
For a live stream, this value is the same as the Camera.height property of the Camera object that is capturing the video stream. For a recorded video file, this value is the height of the video. The NetStream.Video.DimensionChange event is dispatched in the case of recorded videos when this value changes.
Implementation
public function get videoHeight():intvideoWidth | property |
videoWidth:int [read-only] | Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 17.0, Flash Player 18.0 |
An integer specifying the width of the video stream, in pixels.
For a live stream, this value is the same as the Camera.width property of the Camera object that is capturing the video stream. For a recorded video file, this value is the width of the video. The NetStream.Video.DimensionChange event is dispatched in the case of recorded videos when this value changes.
Implementation
public function get videoWidth():intattachCamera | () | method |
public function attachCamera(theCamera:Camera):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 17.0, Flash Player 18.0 |
Specifies a video stream from a camera to be rendered within the texture of the VideoTexture object.
Use this method to attach live video captured by the user to the VideoTexture object. To drop the connection to the VideoTexture object, set the value of the theCamera parameter to null.
Parameters
theCamera:Camera |
attachNetStream | () | method |
public function attachNetStream(netStream:NetStream):void| Language Version: | ActionScript 3.0 |
| Runtime Versions: | AIR 17.0, Flash Player 18.0 |
Specifies a video stream to be rendered within the texture of the VideoTexture object.
A video file can be stored on the local file system or on Flash Media Server. If the value of the netStream argument is null, the video is no longer played in the VideoTexture object.
Parameters
netStream:NetStream |
