Parameters
receive
  A Boolean value that specifies whether incoming video plays on the specified

) or not (
false
). The default value is 
true
.

Description
Method; specifies whether incoming video will play on the specified stream, or specifies the 
frame rate of the video. This method is available only to clients subscribed to the specified 
stream, not to the stream’s publisher.
You can call this method before or after you call the 
 method and actually 
begin receiving the stream. For example, you can attach these methods to a button the user 
presses to show or hide the incoming video stream.
To stop receiving video, pass 0 for 
FPS
. (This has the same effect as passing 
false
.) To 
determine the current frame rate, use 
.
If you call 
NetStream.receiveVideo()
 with a frame rate after calling 
NetStream.receiveVideo(false)
, an implicit call to 
NetStream.receiveVideo(true)
 
is issued.
If the specified stream contains only video data, then passing a value of 
false
 to this method 
stops 
NetStream.time
 from further incrementing.
