FLV looping problem...

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. The FLV frame rate is 24fts. I think the code keep streaming from server. Is there a way to save the animation in cache and loop from cache ?

Cheers

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);
	}
};

Video processing is pretty CPU intensive. It would cost the same amount of resources no matter if you were doing it from a cache or from a streaming server.

I ran in to this issue a long while ago... the trick is this... you need to set the Expires headers and kill the eTags... that will make flash load the flv from cache...

if you watch the net you'll see that even thou it's streamed on the http it only calls it once...

if your on apache use the .htaccess file.. add

# 3months
<FilesMatch "\.(ico|gif|jpe?g|png|flv|pdf|swf|mov|mp3|wmv|ppt)$">
  Header set Cache-Control "max-age=7257600"
</FilesMatch>
# WEEK
<FilesMatch "\.(js|css|swf|gz|min)$">
  Header set Cache-Control "max-age=604800"
</FilesMatch>
# 45 MIN
<FilesMatch "\.(html|htm|txt)$">
  Header set Cache-Control "max-age=2700"
</FilesMatch>


# CMSMS unset ETag
<FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|gz|swf)$">
Header unset ETag
FileETag None
</FilesMatch>
