[Blitmask perf on a slot machine]

Hi Carl,

 

Thx for your answer.

 

The only difference I can see in your demo is that each case is a blitmask and is spinning itself independantly.

In my app, items of a column have to spin together, so my masked area is bigger, 265 x 830p, if I reduce the masked area to 265 x 265, my fps is 60.

 

 

[Blitmask perf on a slot machine]

Hi blitmaskers,

 

Im developing a full hd dual screen air app that display a slot machine on one screen.

My slot machine get 6 columns, each loading 6 (265p x 265p) pictures. 

I use a blitmask (265p x 830p) on each column to spin it.

But once I create the 6 blitmasks I'm loosing 30fps.

If I disable bitmap mode my fps stay at 60fps.

But I have to let the spin work while doing something on the other screen in my same app.

 

Do I have something wrong in my code ?

Or do I reach perf limits ?

Could I improve that ?

 

Here is my code :

/**
		 * loadPhotos
		 */
		public function loadPhotos() : void
		{
			var directory : File = File.applicationDirectory.resolvePath(Common.s_presetManager.getPresetStringValue("/records"));
			pathList = directory.getDirectoryListing();
			
			if (pathList[0].name == ".DS_Store")
			{
				pathList.shift();
			}
			
			var lineItemNB : Array = new Array();
			for (i = 0; i < m_vignetteNb; i++)
			{
				lineItemNB.push(1);
			}
			
			m_photoLoader = new LoaderMax({name:"photoLoader", onComplete:completeHandler});
			for (i = 0; i < pathList.length; i++)
			{
				var line : int;
				if (String(pathList[i].url).charAt(17) == '0')
					line = int(String(pathList[i].url).substr(18, 1)) - 1;
				else
					line = int(String(pathList[i].url).substr(17, 2)) - 1;
				
				m_photoLoader.append( new ImageLoader(pathList[i].url, { container : m_columns[lineItemNB[line]], x : 0, y : line * (265+17), width : 265, height : 265 }) );
				lineItemNB[line]++;
			}
			
			m_photoLoader.load();
		}

private function completeHandler(event : LoaderEvent) : void
		{
			Common.s_logManager.write("[log] vignettes loaded");
			trace("[log] vignettes loaded");
			
			var blitMask1 : BlitMask = new BlitMask(m_columns[0], m_columns[0].x, m_columns[0].y, m_columns[0].width, 829, false, true, 0xffffff, true);
			var blitMask2 : BlitMask = new BlitMask(m_columns[1], m_columns[1].x, m_columns[1].y, m_columns[1].width, 829, false, true, 0xffffff, true);
			var blitMask3 : BlitMask = new BlitMask(m_columns[2], m_columns[2].x, m_columns[2].y, m_columns[2].width, 829, false, true, 0xffffff, true);
			var blitMask4 : BlitMask = new BlitMask(m_columns[3], m_columns[3].x, m_columns[3].y, m_columns[3].width, 829, false, true, 0xffffff, true);
			var blitMask5 : BlitMask = new BlitMask(m_columns[4], m_columns[4].x, m_columns[4].y, m_columns[4].width, 829, false, true, 0xffffff, true);
			var blitMask6 : BlitMask = new BlitMask(m_columns[5], m_columns[5].x, m_columns[5].y, m_columns[5].width, 829, false, true, 0xffffff, true);
			
//			blitMask1.disableBitmapMode();
//			blitMask2.disableBitmapMode();
//			blitMask3.disableBitmapMode();
//			blitMask4.disableBitmapMode();
//			blitMask5.disableBitmapMode();
//			blitMask6.disableBitmapMode();

[VideoLoader loop error]

Hi,

 

My app has to be an AIR app.

I solved the problem by replacing VideoLoader by FLVPlayback.

 

But I reduced my app to the simplest app to test it in a fla.

I don't have the time to do more tests with a standalone flash player but feel free to do it.

 

Here is a zip file containing test project to reproduce the bug.

The 4 flv videos are not inside (about 20Mo) but I can send to you via wetransfer.

 

Best,

[VideoLoader loop error]

A bit more information.

 

In my app (AIR app) when I arrive on the 4 videos screen, I play them :

public function startVideos() : void
{
	trace("video1 time", m_loader1.videoTime);
	trace("video2 time", m_loader2.videoTime);
	trace("video3 time", m_loader3.videoTime);
	trace("video4 time", m_loader4.videoTime);
			
	m_loader1.gotoVideoTime(0, true);
	m_loader2.gotoVideoTime(0, true);
	m_loader3.gotoVideoTime(0, true);
	m_loader4.gotoVideoTime(0, true);
}

Then when I quit this screen I pause videos and goto 0s head position :

public function stopVideos() : void
{
	m_loader1.pauseVideo();
	m_loader2.pauseVideo();
	m_loader3.pauseVideo();
	m_loader4.pauseVideo();
			
	m_loader1.gotoVideoTime(0);
	m_loader2.gotoVideoTime(0);
	m_loader3.gotoVideoTime(0);
	m_loader4.gotoVideoTime(0);
}

When the problem occurs, if I call stopVideos() and then startVideos(), 

videos that was blocked stay blocked on first frame and time trace instructions (inside startVideos() function) indicate a strange value 2.067 or 2.033 instead of 0.

 

What could explain this ?

 

Best,

laugre.

[VideoLoader loop error]

Hi there and thx for support.

Before creating a new topic I found this one http://greensock.com/forums/topic/6567-video-stop-between-loop/
but it's not exactly the same problem.

 

I'm loading 4 different flvs (short time each between 1 and 2 minutes)  using a LoaderMax that have to repeat indefinitly (until the user stop it of course).

After a time videos stop repeating one after the other. They are well rewinded to 1st frame but seem to not be played again.

If I wait a very long time (2h repeating) the 4 videos seem to become blocked on 1st frame.

I first tried to declare repeat property as -1 like this :

m_loader1 = new VideoLoader("flv1.flv", {name:"subCol", container:m_interface.subtileScreen, repeat:-1, width:590, height:350, autoPlay:false, visible:true });
m_loader2 = new VideoLoader("flv2.flv", {name:"subJoie", container:m_interface.subtileScreen, repeat:-1, width:590, height:350, autoPlay:false, visible:true });
m_loader3 = new VideoLoader("flv3.flv", {name:"subSur", container:m_interface.subtileScreen, repeat:-1, width:590, height:350, autoPlay:false, visible:true });
m_loader4 = new VideoLoader("flv4.flv", {name:"subTrist", container:m_interface.subtileScreen, repeat:-1, width:590, height:350, autoPlay:false, visible:true });

m_loader = new LoaderMax({name:"subtile"});
m_loader.append(m_loader1);
m_loader.append(m_loader2);
m_loader.append(m_loader3);
m_loader.append(m_loader4);

m_loader.load();

I also tried to comment repeat:-1 and handle myself play and complete events for each video like this :
 

m_loader1.addEventListener(VideoLoader.VIDEO_PLAY, onVideo1Play);
m_loader1.addEventListener(VideoLoader.VIDEO_COMPLETE, onVideo1End);

private function onVideo1Play(event : LoaderEvent) : void 
{
	trace("[log] onVideo1Play " + event.currentTarget.name + " video time " + event.currentTarget.videoTime);
}

private function onVideo1End(event : LoaderEvent) : void 
{
        trace("[log] onVideo1End " + event.currentTarget.name + " video time " + event.currentTarget.videoTime);
	m_loader1.gotoVideoTime(0, true);
}

And same behaviour, onVideo1End is called that rewind video to 0s, but video is not played even if forceplay = true.
However onVideo1Play is called after onVideo1End.

I think I have something wrong... 
Could you help me please ?

 

Best,

laugre
