Hi, experts

I have the following code that works pretty well. However, it slows down the computer and use almost 50% of CPU. I would like to ask how can I fix the problem so the looping does not slow down computer.

Cheers

B
var connection_nc:NetConnection = new NetConnection();
connection_nc.connect(null);
var stream_ns:NetStream = new NetStream(connection_nc);
purple_video.attachVideo(stream_ns);
stream_ns.play("purple_effects.flv");
 
 
stream_ns.onStatus = function(info) {
	if (info.code == "NetStream.Play.Stop") {
		stream_ns.seek(0);
	}
};

does the CPU spike up to 50% even when you don't use the loop?

is that the only code in the project?  maybe it is something else that is causing a memory leak...

no, without that code, everything else runs fast and smooth..... with that code.... everything slow down :(

I wonder is it because the code keep streaming at every loop ? is it possible to have animation save in cache and run from cache ? if possible

well, my first thought, before I saw your code, was that you were creating a new instance in memory each time...  but Unless the seek method does this natively, I am not sure why this would be happening...

And normally when the video is streamed in, it is cached once it is loaded...  but it looks like you are using progressive download anyway...

have to look into this...  be back later

I can also change to streaming too... progressive or streaming has same slow down computer result...

var connection_nc:NetConnection = new NetConnection();
connection_nc.connect("rtmp://www.site.com/ondemand/media/flash/flv");
var stream_ns:NetStream = new NetStream(connection_nc);
purple_video.attachVideo(stream_ns);
stream_ns.play("purple_effects");


stream_ns.onStatus = function(info) {
      if (info.code == "NetStream.Play.Stop") {
            stream_ns.seek(0);
      }
};

sorry for the delay on the response... must has slipped through the cracks...


I would try these onStatus info codes instead of "NetStream.Play.Stop"

NetStream.Buffer.Flush
NetStream.Buffer.Empty


this is normally what gets passed when a FLV has finished streaming...
