Use the MediaElement.hasTrait(MediaTraitType.DYNAMIC_STREAM)
method to query
whether a media element has a trait of this type.
If hasTrait(MediaTraitType.DYNAMIC_STREAM)
returns true
,
use the MediaElement.getTrait(MediaTraitType.DYNAMIC_STREAM)
method
to get an object of this type.

autoSwitch | 屬性 |
autoSwitch:Boolean
語言版本: | ActionScript 3.0 |
產品版本: | OSMF 1.0 |
執行階段版本: | Flash Player 10, AIR 1.5 |
Defines whether or not the trait should be in manual
or auto-switch mode. If in manual mode the switchTo
method can be used to manually switch to a specific stream.
實作
public function get autoSwitch():Boolean
public function set autoSwitch(value:Boolean):void

maxAllowedIndex | 屬性 |
maxAllowedIndex:int
語言版本: | ActionScript 3.0 |
產品版本: | OSMF 1.0 |
執行階段版本: | Flash Player 10, AIR 1.5 |
The maximum allowed index. This can be set at run-time to provide a ceiling for the switching profile, for example, to keep from switching up to a higher quality stream when the current video is too small to handle a higher quality stream. The default is the highest stream index.
實作
public function get maxAllowedIndex():int
public function set maxAllowedIndex(value:int):void
擲回值
RangeError — If the specified index is less than zero or
greater than the total number of dynamic streams.

Indicates whether or not a switch is currently in progress.
This property will return true
while a switch has been
requested and the switch has not yet been acknowledged and no switch failure
has occurred. Once the switch request has been acknowledged or a
failure occurs, the property will return false
.
