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

public function canSeekTo(time:Number):Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | OSMF 1.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Indicates whether the media is capable of seeking to the specified time.
Parameters
time:Number — Time to seek to in seconds.
|
Boolean — Returns true if the media can seek to the specified time.
|
seek | () | method |
public final function seek(time:Number):void| Language Version: | ActionScript 3.0 |
| Product Version: | OSMF 1.0 |
| Runtime Versions: | Flash Player 10, AIR 1.5 |
Instructs the media to jump to the specified time.
If a seek is attempted, dispatches a seekingChange event.
If time is non numerical or negative, does not attempt to seek.
Parameters
time:Number — Time to seek to in seconds.
|
seekingChangeEnd | () | method |
