Usage
my_ns.bufferLength:Number
Description
Read-only property; the number of seconds of data currently in the buffer. You can use this
property in conjunction with
being full—for example, to display feedback to a user who is waiting for data to be loaded into
the buffer.
Example
The following example dynamically creates a text field that displays information about the
number of seconds that are currently in the buffer. The text field also displays the buffer length
that the video is set to, and percentage of buffer that is filled.
this.createTextField("buffer_txt", this.getNextHighestDepth(), 10, 10, 300,
22);
buffer_txt.html = true;
var connection_nc:NetConnection = new NetConnection();
connection_nc.connect(null);
var stream_ns:NetStream = new NetStream(connection_nc);
stream_ns.setBufferTime(3);
my_video.attachVideo(stream_ns);
stream_ns.play("video1.flv");
var buffer_interval:Number = setInterval(checkBufferTime, 100, stream_ns);
function checkBufferTime(my_ns:NetStream):Void {
var bufferPct:Number = Math.min(Math.round(my_ns.bufferLength/
my_ns.bufferTime*100), 100);
var output_str:String = "<textformat tabStops='[100,200]'>";
output_str += "Length: "+my_ns.bufferLength+"\t"+"Time:
"+my_ns.bufferTime+"\t"+"Buffer:"+bufferPct+"%";
output_str += "</textformat>";
buffer_txt.htmlText = output_str;
}
