NetStream class 649
NetStream class
Availability
Flash Player 7.
Note: This class is also supported in Flash Player 6 when used with Flash Communication Server.
For more information, see the Flash Communication Server documentation.
Description
The NetStream class provides methods and properties for playing Flash Video (FLV) files from
the local file system or an HTTP address. You use a NetStream object to stream video through a
NetConnection object. Playing external FLV files provides several advantages over embedding
video in a Flash document, such as better performance and memory management, and
independent video and Flash frame rates. This class provides a number of methods and properties
you can use to track the progress of the file as it loads and plays, and to give the user control over
playback (stopping, pausing, and so on).
Method summary for the NetStream class
The following methods and properties of the NetConnection and NetStream classes are used to
