Description
Read-only property; the number of seconds assigned to the buffer by
NetStream.setBufferTime()
the number of seconds currently in the buffer, use
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;
}
