NetStream class

107

Returns

Nothing.

Description

Method; seeks the specified number of seconds into the recorded stream that is currently
playing, either from the beginning of the stream or from the current position. This method is
available only to clients subscribed to the specified stream, not to the stream’s publisher.

If you require an accurate return value from seeking, you may need to change the
Application.xml file’s

EnhancedSeek

flag on the server.

EnhancedSeek

is a Boolean flag in the Application.xml file. By default, this flag is set to

false

. When a seek occurs, the server seeks to the closest video keyframe possible and starts

from that keyframe. For example, if you want to seek to time 15, and there are keyframes only
at time 11 and time 17, seeking actually starts from time 17 instead of time 15. This is an
approximate seeking method that works well with compressed streams.

If the flag is set to

true

, some compression is invoked on the server. Using the example above,

if the flag is set to

true

, then the server creates a keyframe—based on the preexisting

keyframe at time 11—for each keyframe from 11 through 15. Even though a keyframe does
not exist at the seek time, the server generates a keyframe. This, of course, involves some
processing time on the server.

EnhancedSeek

tag, see “Application.xml file” in Managing

Flash Media Server.
