ActionScript 3.0 :: Use Filters On Ios Mobile Devices (iPhone/iPad) Using GPU Rendering
Nov 15, 2011
how to use filters (specifically a glow filter) on a mobile devices (specifically the iPhone) when using GPU rendering and high resolution. At the time, there was no answer... filters were unsupported. Period.
I can report that I have gotten a color matrix filter for desaturation AND a glow filter working on the iPhone and the iPad using GPU rendering and high resolution.
The solution, in a nut shell is as follows:
1: Create your display object... ie: a sprite.2. Apply your filter to the sprite like you normally would.3. Create a new bitmapdata and then draw that display object into the bitmap data.4. Put the new bitmapdata into a bitmap and then put it on the stage or do what you want.
When you draw the display object into the bitmapdata, it will draw it WITH THE FILTER!So even if you put your display object onto the stage, the filter will not be visible, but the new bitmapdata will!
Here is a sample app I created and tested on the iphone and ipad
[Code].....

I tried to apply a filter to a video on mobile phones and had a strange effect:
When I apply the filter to a 24 FPS source video the resulting frame-rate after applying the filter drops to about 7 FPS. But if I use a 8 FPS source video the frame-rate is even lower at about 3-4 FPS. I expected an higher, or at least equal resulting framer-rate with the 8 FPS source video. What's the reason for this behavior?
I use the Flash Player 10.1 for Android 2.2 and the Google Nexus One.

I have a website [URL]. I added a flash mp3 player that plays a sound clip when you go to the page. I know Flash doesn't work on the iPhone OS, but is there a way to get this type of mp3 player to work on an iPhone? I'm thinking maybe a javascript mp3 player. What I would ultimately want is to replace my flash mp3 player with a different mp3 player and have it so the player is available on Windows and Mac computers as well as iPhone devices.

I'm interested in developing for the iPad and iPhone, but I'd prefer not to learn Apple's whole development stack (and good golly, I sure don't want to go back to manual memory management). Oh, sure, I could learn it, but I don't have that level of commitment to the environment at this point. I've got professional experience with Flex already, so I'm intrigued by Adobe's move to make Flash/Flex compile to the iPhone and iPad. My question is: how promising of a development path will Adobe's Slider be? Are we likely to see Slider publicly available in a reasonable timeframe (Adobe: "An early mobile branch of the Flex framework is expected to be available in 2010")? Are we likely to see reasonable performance? Are there development hurdles that haven't become clear yet? Heck, is it all just vaporware? There's pretty limited information available so far, as far as I've seen, but I'm interested in people's predictions, even if they're speculative.

I have built a multi-touch application which is based on a Java EE backend and combined with BlazeDS to a Adobe Flex frontend. The application runs on a DIY-Multi-Touch which I built. Now I want to use another solution. The Adobe Flex frontend (with a multitouch library) and the BlazeDS adapter should be replaced by a solution which covers iPhone/iPad, Android and commercial Multi-Touch displays.
The problem is the iPad/iPhone, there is no Flash Player runtime (not the jail-breaked ones), but the application should be runnable also on those devices. So Adobe Flex and a Java frontend (no JVM on the iPhone/iPad) is not possible anymore. At first, starting the developing of the application it was not neccessary, to run it on Apples mobile devices, but this changed So, what can I do, using HTML5? So I can use it for Android and iPhone/iPad. But I also want to make it possible to use it on a commercial multi-touch-display and normal display with a mouse (I only have gestures for one finger, the 2-finger gestures are not neccessary). Are there any frameworks that allow this? Because I do not want to create several frontends (App for iPhone/iPad on Objective-C and a Adobe Flex for all other devices), it would be great if I can build a frontend for all devices.

I have a grails application using jquery mobile. I am hoping to find some way to access the camera on the devices. I thought about using flash to grab the webcam but that obviously wont work on Apple devices. Does anyone know of a way to do it and keep it all browser based? I am hoping that there is a plugin somewhere or maybe html5 has some magic in there that supports it.

I'm currently using this to detect if the visitors have flash installed or not and if not right away I'm assuming they are iPhone users but then now it seems it doesn't always work like I wish to because sometime they being redirect to the version of flash of my site and sometime the person who got flash installed also redirect to an iPhone version of my site.[code]the thing is how would I detect if they are iPhone/iPad/iPod/AppleTV something like that and redirect them to the flash=false URL and if they are non of the above will be redirect to flash=true?

I have designed a flash website using Flash CS5 using Actionscript 3.0 here: URL...It displays fine on a computer browser but the client is determined to view it on his mobile device (and all mobile devices).From my understanding; Flash is not supported by all mobile devices, although others have told me contradictory information.I know Iphone do not support Flash and I don't think Blackberry do either. But some Androids display flash content? Right?Can someone please offer me some advice on mobile devices when it comes to viewing Flash content...?

My OS is Win 7 and I have the windows test versionof Flash Builder Burrito.There I can only develop for Android devices.I've heard it's only possible to develop forthe iPhone/iPad with a Macintosh computer.Or is there a trick to develop for iPhone/iPad on Windows PC with Adobe software(because I don't want to pay a second time for Adobe software for MAC)and only copy the result to a Macintosh?
Is it possible in the MAC version of Flash Builder Burrito to develop for iPhone/iPad (and also for Android)?Or have I to use a different IDE for iPhone/iPad apps becauseApple wants native apps and Flash builder burritois only for AIR/Flash app development?

We're seeing very different results from the same files being packaged for iPhone verses iPad. Not having a lot of luck getting things to run smoothly on the iPad when they work great on the iPhone. The iPhone versions also run great on the iPad even though it has to scale down all the retina quality images. I feel like I'm missing some important difference between the two?

Ive just started messing around with flash cs5 and trying to make a simple app for the ipad and have it eventually on the app store. The thing that has me concerned is that the animations seem to be struggling on the ipad.
im running it at 24 fps and there is zero physics and very simple AS3 for touch to stop animations. But the animations are running so slowly and the sound layer is no longer in sync with the animation.
Does anyone have any experience with this that can advise me on what the issue may be? why would a simple flash cs5 animation struggle as an ipad app? would the file type of the sound files be an issue?
