I looked at this demo: [URL] Flex seems very slow compared to silverlight 3. Unfortunately can't see pure flash but should flex be forbidden if performance is top requirements compared to Flash ?
View 3 RepliesI get a working application in Flash made that lets the user click to create blocks which subsequently gravitate towards the mouse. I made the exact same thing in Processing too, just to compare speeds.However, when I run the Flash version and add around 15-20 blocks, the framerate drops to 5-10 FPS.In the Processing version I can add ~60 with no noticeable slowdown. What's the deal, Flash?
Links to each version's source:
Flash version
Processing version
Here is the source for each in case you are a wizard and can help just by glowering at the code sternly and telling it to behave:
Flash version:
blocks.fla
import flash.events.Event;
import flash.display.MovieClip;

With Adobe now you can make Flash/Flex compile to the iPhone and iPad. How does that compare to MonoTouch? Does the Adobe solution really compile into native iOS code? Or is it just a iOS Air container that runs your code which is able to access the natife iOS calls through the Air container? I'm wondering what is different with Adobe compared with MonoTouch. I just want to know the differences between the two technologies. If any. Or do they work exactly the same way on principle.
View 3 RepliesI have the crossdomain.xml set and I've also tried setting the local playback to network only and still no luck. What I'm trying to do is have the user upload an image, then I pass that value over through PHP and a directory is created. After that hits it returns with the path and I try to load the image as a thumbnail and thats when i get the security error.

Will I take a big hit in performance using nested ViewStacks? Should I strive to handle all navigation in one ViewStack and push children manually or will the affected performance be negligible?
eg.
<viewstack>
<tabnavigator />
<tabnavigator />
<tabnavigator />
</viewstack>
We have a medium size Flex 3.6 application that contains around 20 different page views (managed via a single lazy ViewStack) each having multiple components. Most use custom renderers.All model data is loaded at startup and changes to model instances are communicated via binding and/or collection change events.Once the user has viewed each page at least once, all page views are instantiated and happily listen to update events.Which in effect means that each time a model instance changes, all interested views receive that event and compute derived data or trigger item-renderers.I have tested and confirmed this behaviour in a proof-of-concept application. Even when setting a list to being invisible, it still listens to collection change events and invalidates any renderer affected.What would you do?

How to add accessibility requirements to a swf created using mxml+flex sdk? I have a few buttons and textfields in the swf and the impaired user should be able to increase the button size and text size while using the swf. I've looked into flex built-in accessibility features, but its not what I require. I want to run the swf standalone without a browser, so preferably change the size with a visual widget.
View 1 RepliesI use Flash mainly for Slideshow Pro content and before CS5 I have used CS3 and CS4. I have never noticed issues with speed before, but since upgrading to CS5, my work has slowed to a crawl.
I am on a 64 bit machine Windows 7 machine very fast machine with 12 GB of memory, and while I realise that Flash is not a 64 bit program and can therefore not use all of that, I am wondering why it is so much slower than was CS4.
I have read a few articles, I can't see why one would use html5 instead of flash so any few examples which could show the advantages ?
View 5 RepliesI am noticing a weird behavioral on some pages with flash file that loads XML in IE7 or IE8. If the browser is visible, the XML loads right after the flash. If the browser is minimized, while the load xml happens, it takes like 500 - 900 ms to load the XML. The same issue if its loading an image, say JPG.
View 2 RepliesI had a project requirement which was to stream video to people across the globe (max 100 simultaneous connections) and i was under the impression that a single HTTP server is sufficient. However, a friend of mine said i will have to use an FMS server. How does this basically work ?
If i record video from my webcam and store it for future consumption, where will it be stored ? On my site server ? or on the FMS server What is so special about an FMS server ? Can i turn any server into an FMS server I read somewhere that streaming video via my own server does not allow the user to jump to a particular part in a video. Is this true If the requirement is to stream live video to people, how does this work ? Does the video from the source (webcam) get transferred to my server and then to the FMS server or directly to the FMS server I'm pretty confused about the FMS server concept and some articles or links would really help too, however your expert answers will be invaluable

View 1 RepliesI am in the planning phase of a new multi-user client/server app using Flash via Flex and AIR. I am trying to decide which web platform/stack is the best suited for this? I have used RoR in the past, but as i understand, RoR is single-threaded, and is therefore not the ideal choice for handling potentially thousands of simultaneous requests. I have done some reading about Scala and Lift and that is an intriguing option, but i was wondering if there are other languages/frameworks out there that would work well for my project?

View 3 RepliesThere is a number of Flash and AJAX based uploaders around. I need a file upload component for an existing form in an existinc application, so I have very specific requirements for it. Maybe somebody knows one off the top of their head and saves me a lot of research.
I need a file upload component that has a progress bar and "upload" button next to it (= standalone functionality, no connection to the submit event of a surrounding form).
It should be either Flash or Prototype based. No JQuery or Moo, as the app runs with prototype.
If server-side scripting is needed, it must be PHP. No Perl, no ASP.
On successful upload, I need a custom Javascript function triggered. (I need to update a file list that is displayed on the same page.)
The possibility of filtering file names before upload (no Umlauts, spaces..) would be a plus.

I have a flash application which consist of Grid Components, Button, Label, and Combo-box Components. All these components are used more than 70 times(simultaneously) with in the application. So Its takes too much of memory. So How can I test the memory usage of each component at the time of running. Is there any plug-in available for browsers to find the memory usage. I'm using flash CS3 and ActionScript 3.0. The application suppose to run in browsers.

I'm devloping some library classes for flocking/steering behaviours on large numbers of objects (2000+). I'm finding that at < 500 instances, performance is reasonable. As the numbers increase, framerate bogs down.
I've seen remarkable performance with libraries such as Flint or Box2D with ridiculous #'s of particles / objects, so it should be possible to optimize / refactor my code to be a bit better.
I'm aware of the basic optimizations, such as bitwise operations and optimized for loops. Are there any more fundamental approaches I should be considering? For example, currently each instance is a vector-based MovieClip. Would working with BitmapData be more efficient?
On Flash Kit there is a thread that is worrying me because I haven't used CS4 yet but by the sounds of things people are finding it run really slow when you use CS4 for animating or open a CS3 file that would normally run fast.
View 14 RepliesI am working on an Adobe AIR (2.0) application that contains a feature to allow users to print documents (such as salary slips). Those documents are originally in PDF format. Due to circumstances we cannot directly display those PDFs in the AIR application (for example using flash.html.HTMLLoader). Therefore we convert the PDFs to SWFs (using the pdf2swf tool, see The SWFs are loaded into the application using a mx.controls.SWFLoader, like so:

Does using actionscript descrease the size of a file as compared to working with the timeline? For example, would using AS to cause a graphic to fade away be more effecient (as far as file size and performance) than using a symbol effect or even changing the alpha frame by frame? I've been using flash for a year now. I've never learned AS because I thought I could do everything from the timeline. But my files always seem so large. And most animation effects seem choppy in comparison with what I see online. Is AS the key to changing that?

View 5 RepliesI work on a project where FMS will be used as the main streaming server. We are going to use p2p/multicast technology which is available in FMS. My first question is : What are the approximate hardware requirements for such a server ? REMARK : this server will be connected to a switch with 1G/bits ports. If we use p2p/multicast technology the maximal number of users which the system can handle is (theoretically)unlimited, is this right ?

View 1 RepliesI am working on a flex application. The application occupies 100% of the browser screen, but it is slow to load. How should I improve the performance, what are the best techniques one should follow for improving the performance of a flex App. I did try some stuff though, I am not using relative layout instead i am using absolute layout and putting the buttons/images etc at exact places in a Canvas, still i feel it is slow. Can I profile the App or flex code to see where exactly the app is taking the maximum time to execute.
View 3 RepliesSame file streamed from FMS4 (same on 3.5) with rtmp protocol has very poor quality compared to real file quality. Is there some low level configuration to do on Flash Server? Is the streaming server making some kind of transcoding before sending the stream? Or it can be Flash Player? Tried unchecking "hardware acceleration" but nothing changes. I am on a local gigabit network, so no network bottlenecks. Video seems very pixelated on the edges (not soft/antialiased). These are the file details:
