Example

The following example creates a progress bar using the Drawing API and the bytesLoaded and bytesTotal properties. The bar displays the progress of the operation as video1.flv is loaded into the video object instance called my_video. A text field called loaded_txt is dynamically created to display information about the loading progress as well.

var connection_nc:NetConnection = new NetConnection();
connection_nc.connect(null);
var stream_ns:NetStream = new NetStream(connection_nc);
my_video.attachVideo(stream_ns);
stream_ns.play("video1.flv");

this.createTextField("loaded_txt", this.getNextHighestDepth(), 10, 10, 160, 22);
this.createEmptyMovieClip("progressBar_mc", this.getNextHighestDepth());
progressBar_mc.createEmptyMovieClip("bar_mc", progressBar_mc.getNextHighestDepth());
with (progressBar_mc.bar_mc) {
    beginFill(0xFF0000);
    moveTo(0, 0);
    lineTo(100, 0);
    lineTo(100, 10);
    lineTo(0, 10);
    lineTo(0, 0);
    endFill();
    _xscale = 0;
}
progressBar_mc.createEmptyMovieClip("stroke_mc", progressBar_mc.getNextHighestDepth());
with (progressBar_mc.stroke_mc) {
    lineStyle(0, 0x000000);
    moveTo(0, 0);
    lineTo(100, 0);
    lineTo(100, 10);
    lineTo(0, 10);
    lineTo(0, 0);
}

var loaded_interval:Number = setInterval(checkBytesLoaded, 500, stream_ns);
function checkBytesLoaded(my_ns:NetStream) {
    var pctLoaded:Number = Math.round(my_ns.bytesLoaded/my_ns.bytesTotal*100);
    loaded_txt.text = Math.round(my_ns.bytesLoaded/1000)+" of "+Math.round(my_ns.bytesTotal/1000)+" KB loaded ("+pctLoaded+"%)";
    progressBar_mc.bar_mc._xscale = pctLoaded;
    if (pctLoaded>=100) {
    clearInterval(loaded_interval);
    }
}
