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
mediaproperty. - Control the media using the MediaPlayer's methods, properties, and events.
- When done with the LightweightVideoElement, set the MediaPlayer's
mediaproperty 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).

The NetClient used by this object's NetStream. Will be null until this object has been loaded (as indicated by its LoadTrait entering the READY state).

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| Versión del lenguaje: | ActionScript 3.0 |

| Versiones de motor de ejecución: | 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.

| Versiones de motor de ejecución: | 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.
