Client-Side ActionScript Language Reference

If you pass the 

 parameter to limit the frame rate of the video, Flash Media Server attempts 

to reduce the frame rate while preserving the integrity of the video. The server sends the 
minimum number of frames needed to satisfy the desired rate between every two keyframes. 
Keep in mind, however, that i-frames (or intermediate frames) must be sent contiguously; 
otherwise, the video will be corrupted. Therefore, the desired number of frames is sent 
immediately and contiguously following a keyframe. Since the frames are not evenly 
distributed, the motion appears smooth in segments punctuated by stalls.

Example

The following example opens a stream and specifies that the video play at a specified rate:

var my_ns:NetStream = new NetStream(my_nc);
my_ns.receiveVideo(false);   // Don’t display video being published.
// Later....
my_ns.receiveVideo(12);      // Display video at 12 FPS.

Availability

Usage

public seek(offset : Number) : Void

Parameters

  The approximate time value, in seconds, to move to in an FLV file. The playhead 

moves to the keyframe of the video that is closest to 

. 

■

To return to the beginning of the stream or playlist, pass 0 for 

.

■

To seek forward from the beginning of the stream or playlist, pass the number of seconds 
you want to advance. For example, to position the playhead at 15 seconds from the 
beginning, use 

myRecordedStream_ns.seek(15)

.

■

To seek relative to the current position, pass 

myRecordedStream_ns.time + n 

or 

myRecordedStream_ns.time - n

 to seek 

 seconds forward or backward, respectively, 

from the current position. For example, to rewind 20 seconds from the current position, 
use 

myRecordedStream_ns.seek(my_ns.time - 20)
