LightweightVideoElement is a lightweight alternative to VideoElement. Whereas LightweightVideoElement supports only a subset of video delivery modes (specifically progressive and simple RTMP streaming), VideoElement supports all video delivery modes.
The LightweightVideoElement uses a NetLoader class to load and unload its media. Developers requiring custom loading logic for video can pass their own loaders to the LightweightVideoElement constructor. These loaders should subclass NetLoader.
The basic steps for creating and using a LightweightVideoElement are:
- Create a new URLResource pointing to the URL of the video stream or file containing the video to be loaded.
- Create a new NetLoader.
- Create the new LightweightVideoElement, passing the NetLoader and URLResource as parameters.
- Create a new MediaPlayer.
- Assign the LightweightVideoElement to the MediaPlayer's
media
property. - Control the media using the MediaPlayer's methods, properties, and events.
- When done with the LightweightVideoElement, set the MediaPlayer's
media
property to null. This will unload the LightweightVideoElement.
The LightweightVideoElement supports Flash Media Token Authentication, for passing authentication tokens through the NetConnection.
The LightweightVideoElement has support for the Flash Player's DRM implementation.
Note that the startDate
, endDate
, and period
properties of the DRMTrait on this element correspond to the voucher validity before
playback starts. Once playback begins, these properties correspond to the playback
time window (as found on flash.net.drm.DRMVoucher).

deblocking:int
언어 버전: | ActionScript 3.0 |
제품 버전: | OSMF 1.0 |
런타임 버전: | Flash Player 10, AIR 1.5 |
Indicates the type of filter applied to decoded video as part of post-processing. The default value is 0, which lets the video compressor apply a deblocking filter as needed. See flash.media.Video for more information on deblocking modes.

defaultDuration:Number
언어 버전: | ActionScript 3.0 |
제품 버전: | OSMF 1.0 |
런타임 버전: | Flash Player 10, AIR 1.5 |
Defines the duration that the element's TimeTrait will expose until the element's content is loaded. Setting this property to a positive value results in the element becoming temporal. Any other value will remove the element's TimeTrait, unless the loaded content is exposing a duration.

smoothing | 속성 |
smoothing:Boolean
언어 버전: | ActionScript 3.0 |
제품 버전: | OSMF 1.0 |
런타임 버전: | Flash Player 10, AIR 1.5 |
Specifies whether the video should be smoothed (interpolated) when it is scaled. For smoothing to work, the runtime must be in high-quality mode (the default). The default value is false (no smoothing). Set this property to true to take advantage of mipmapping image optimization.

public function get smoothing():Boolean
public function set smoothing(value:Boolean):void

Constructor.
매개 변수resource:MediaResourceBase (default = null ) — URLResource that points to the video source that the LightweightVideoElement
will use. For dynamic streaming content, use a DynamicStreamingResource.
| |
loader:NetLoader (default = null ) — NetLoader used to load the video. If null, then a NetLoader will
be used.

오류
ArgumentError — If resource is not an URLResource.
