How would one go about caching / managing many large files (videos) on a user's computer via browser mechanisms (plugins are acceptable solutions). From what I can tell, local storage is about database type data, not files.

I'm looking for javascript libraries and code that can simulate localStorage on browsers that do not have native support.Basically, I'd like to code my site using localStorage to store data and know that it will still work on browsers that don't natively support it. This would mean a library would detect if window.localStorage exists and use it if it does. If it doesn't exist, then it would create some sort of fallback method of local storage, by creating its own implementation in the window.localStorage namespace.I understand that Flash and Silverlight can be used for local storage as well, but haven't found anything on using them as a fallback for standard HTML5 localStorage. Perhaps Google Gears has this capability too?Please share any related libraries, resources, or code snippets that you've found! I'd be especially interested in pure javascript or jquery-based solutions, but am guessing that is unlikely.
View 8 RepliesPresently I'm building an interactive CD-ROM based presentation for stand alone individual machines. I'm using AutoPlay Media Studio 7 to package a flash movie along with a licensed adobe reader and adobe flash player. One of the buttons on the autoplay package will install and create folders and files on a local machine.
I've uploaded a file for you flash gurus out there to look at, it may help to examplify what I'm trying to achieve. What I'd like to do, is to be able to use a file (perhaps XML?) that the flash movie can reference and make changes to. If this is possible then such file would be included in the AutoPlay package (see background info above) and installed on the local machine.Security is an extremely low key issue here and the username password is simply a means for flash to lookup and recognise an existing user (if there is one) and set the states of some variables.
Why? - The project is like an interactive training manual with questions and animated examples split into 8 modules. I would like to be able to provide users a means with the of not having to review previous modules by logging in at the login frame.
Code:
Assigned to 'signInUser' button
on (release) {
if (user_name == storedUserName) {
if (pass_word == storedPassword) {
[code].....
I want to make a simple tick box questionaire in Flash (AS2) that stores data to a local text file when the user has submitted the form. So simple stuff like are you Male of Female etc... Is it possible for flash to store this information somewhere. It is for touch screens in an exhibition space so it wont be online.
View 1 Repliesi am hoping that someone can put me right on this question (apologies if this the wrong forum too)...i have an .ipa file that uses xml for it's content. i can load the xml/images etc... fine from both a url and also locally on the handset.but what i wanting/trying to do is for the .ipa to check to see if there is an updated xml doc/images from the url - if there is then it downloads/saves the xml doc and any associated images to a local folder/location - if there isn't (or the handset can not access the internet) it simply loads up the xml and images locally.i have seen a few methods of doing this - but am not sure how it all ties together with flash?
View 7 RepliesI would like to add local storage to an existing Flash webapp that up until now uses a web server to store data (database and media files). What are my options? I'd like to reuse the code of the Flash webapp and run it inside a browser if possible (which, if I'm not mistaken, is not possible with Adobe AIR).
View 1 RepliesI have a HTML box and load a local html file from the project. In this HTML file I use jquery and I want to load an image from my user directory. I see the image from my user directory but jquery doesn't works. I get this error:

But if I load an image from the app workspace, everything works fine (I see the image and Jquery works). Is this a policy problem? The error says that is a "null object reference" problem, but this can't be true...
There is a small feature I have implemented that makes uses of the Local Shared Objects to work properly.
I wish to be able to help the user self-diagnose if he is unable to use the said feature because he refused access for this computer to writing local shared objects and give him instructions to work around the issue if it applies to him.
I'm looking for something similar to the muted property of the Microphone class [URL] or the Camera class.
Is it possible to set the local storage limit for shared objects using action script rather than the Flash Player context menu?
View 2 RepliesI have an actionscript app which needs to use SharedObjects. I see how if the user doesn't allow the Flash Player to access local storage, the security settings panel automatically pops up and asks for user input.
My problem is that my app runs with a 1x1 pixel stage, because it doesn't display anything. So the user will never see that panel and the program will seem to hang.
What I want to do is to somehow detect that the user doesn't allow the Player to access local storage so that I can open a new window large enough to display that panel.
The only way I've been able to detect this so far is to try to call SharedObject.flush() and check the return value, but that displays the settings panel.
Anybody happen to know how I can show the 'Local storage' panel in AS3 from an AIR application?[code]
View 3 RepliesI'm doing a small webapp where I want to use a fairly small amount of Local Storage for SharedObjects.The challenge is to cater to all visitors, including those that might have turned down their local storage allowance to 0 bytes (inactivated).Now, what happens is that the first flush method call triggers the local storage dialog box.In the case that the user has inactivated local storage, I don't want to ask them to raise it - instead I want to avoid using SharedObjects for the remainder of the session.I haven't found a way to test for the capacity of the local storage. What I can find is the size property of the SharedObject class. This doesn't work however as it only reports a size greater than 0 if there has already been an object written to this application domain.
View 0 RepliesIs there any hook to react to a user drag and dropping a text file onto a browser? If the user drops a text file onto the browser with my page loaded, I'd like to be able to open the contents of the text file using javascript. I don't think this is possible, but just checking.
Is something like this possible in flash?
As an alternate, the user could specify a file path for me, then I could open the text file and read it. Seems like this is a security risk and probably won't be allowed, but just checking. It looks like this is possible with flash 10?
While trying to develop some Android app I ran into the following problem:I load an swf file to a WebView, that makes js calls. I want to catch those js calls, so I useWebViews.addJavascriptInterface() to do so.Everything worked just fine when i loaded the swf file from a remote server, but when I load the same swf file form the Android file system, the javascript methods seem not to run (at least I cannot see them).
View 1 RepliesI realize it is possible to play audio with Flash and HTML5 by passing a URL.
However, is it possible to get a reference to an audio file using a file browser (either with HTML5 or Flash), to then play this local file, again using either Flash or HTML5?
Of course, this should happen without the interference of a server. Since the file is already on the local system, it does not make sense to route it through a server only to receive the same file again.
Is it possible to pass the contents of an array to JavaScript code which then creates a text file on the local machine?
View 10 RepliesI can read an image from hard drive and get a ByteArray from its source. Is there any way to store those bytes in local SQL database? What datatype for this field I need to choose?Or maybe there is a more clever way to save an Image file itself into AIR SQL?..
View 1 RepliesDoes html5 developers animate vector graphics in any way? I'm talking about straight key-frame vector animation, such as what flash does. Is the way to do this basically using javascript to manipulate SVG graphics such as what [URL] does? which is a bit weird to me since it's been supported in browsers for quite some time) or does html5/canvas lend itself someway to vector graphics animation? I'm just trying to understand what's the "new" way developers will animate vectors on the web if/when flash plug-in eventually dies.
View 3 RepliesSo now Adobe has pulled the plug on Mobile Flash and are pushing more for HTML5, and Silverlight has pulled the plug too, what's next for interactive video content. So if they die out (as they are currently trying to do) how do we access web cams (or even phone cams) on websites. The HTML5 Media Capture looks like it doesn't support streams only Files, so that could be out, is there any alternatives at the moment, or in the near future?

View 1 RepliesI am trying to capture the microphone and send the recording to my server.. I tried this method here but it records only a big WAV and the upload can be slow sometimes. Is there a way to capture the voice and compress it on the client side? Best method would be to send the recording while recording, but I have no Idea if this is possible. (It works for YouTube Live Webcam recording, it must work for Audio only too..)

I am developing a web based multi-player board game and wondering what the best language for the UI would be? Its a board game similar to Go but a lot simpler.I have two options flash or the much touted HTML5 with JS. I have to learn both though I have basic knowledge of JS.The problem with flash is I have to pay for the server component but the UI development could be easier and have a richer look and feel to it. With HTML5 + JS there is no cost involved but the UI development I feel will be clunky and not smooth. This I am not sure.
View 6 RepliesI had created an HTML5 Canvas WebGL game in January for the Mozilla Game On 2010 competition (pretty late, I know - I never released it until yesterday). Now I want to port it to Flash ActionScript 3.0 for a college assignment.I'm well versed with both static languages like C/C++ and Java; and dynamic languages like Python and JavaScript. However I don't know ActionScript, but since it's a subset of ECMAScript it should be pretty easy to understand.I want to learn programming in ActionScript 3.0 so that I may be able to port my game in Flash. To be more specific, I want to know more about:How is ActionScript different from Browser and Server-Side JavaScript, and basics.OpenGL programming in ActionScript (including loading textures, shaders, etc).How to create a HUD in Flash using a 2D HTML5 Canvas like API (in my game I have 2 canvases, one for the 3D game and another overlaying it for the heads-up display).Support for vector and matrix calculations in ActionScript.How to load assets like audio and sprites in Flash.It would be even more helpful if you would check my source code in JavaScript and suggest the best possible way for me to tackle this problem.The code for the main game engine and the game itself may be found in my Github repository.
View 2 Replieshow to store data local hard disk in flash applications
View 1 RepliesI'm creating my first web application and I'm really confused as to what technology to go for. My application needs to look serious (like an application), it doesn't need many colorful graphical interfaces. It only needs a toolbar, a tab bar, a split panel (preferably 3 columns), an easily-formatable text field, and a status bar. It will connect to a MySQL database through PHP (unless I go for GWT). Users will upload files. My evaluation of the options:
Flex: Probably the easiest to develop but I'm pretty sure my application is something one would use on an iPad and with Flash's future on the iPad still unsure, I don't want to take the risk, otherwise Flex would've been my choice. jQuery: I've heard a lot about it and a lot of people recommend but I don't know how easy it is to use and how customizable the look of my app is. GWT: The problem with GWT is that it doesn't have many widgets. Another problem is that I'm gonna have to host the files in AppEngine's datastore and transfer them back and forth to a web server that will do operations on them (I need to process them) which adds more traffic and slows the process which worsens the user experience. Closure: It has a nice toolbar and a nice text field. I'm not sure how easy it is to use. Plus, I read an article that makes it sound really bad.
[Code]...
I built a prototype in Adobe Flex, they (customers) liked it. Everything was fine until they later told me that iPads / iOS needs to be supported too.I checked out Adobe's Packager for iPhone. We're evaluating that and we will know if it works out in a couple of days. (We need to get through Apple's red tape and certificates raj so this angle is delayed by a few days!)
There is a growing voice for using HTML5/Canvas as a technology platform itself. And despite being quite proficient in Flex, I think this makes sense.
I'm in need of a HTML5 library that can:
Render "widgets" i.e. containers with forms and components(this should be easy and possible using POHJC - Plain old HTML,JavaScript and CSS )Provide a Tree like control for laying out some data Provide a Canvas where data structures can be represented as basic shapes Provide drag and drop capabilities between Trees, Buttons and Canvas Provide some sort of Tab Navigator container (I guess JQuery works here) Interact with back-end services (JSON/XML calls will be okay, but mapping directly with back-end entities will be awesome!)Renders on latest versions of major browsers, Android OS and iOS (WebKit for mobile?)
I'm ready to give JQuery & JQuery UI a try. I looked at Sencha / ExtJS but it seems we need to maintain two code bases one for normal browsers and the other for mobiles (is that correct?)Single code base, I don't want to suggest to them that multiple code bases for the client need to be maintained. That's a last resort option and would lead to complete ruling out of HTML5 with Flash apps and native apps being developed.Canvas capabilities - I don't want to work with raw canvas and shape tags. This too is a last resort option. Is there any abstraction available?
