I read about a project that enables the developer to program a HTML5 web sockets application that is compatible with older browsers by automatically falling back to using a flash method.
View 1 RepliesI told my boss to use HTML5 with a fallback on FLASH.But he said he wants FLASH as the first option, and if the browser (ipad or any other) can't recognize the FLASH , it should play the MP4 file we got. I suggested HTML5 with fallback on Flash. But he wants the opposite.
Using SWFObject (google it) and a SWF Controller (like FlashMediaPlayback.swf).It's very important to understand that the iPad has limitations with video size. So the MP4 file can't be bigger than 720p and 160kbps for audio.

I'm trying to have a flash video, with fallback to the html5 video element for those browsers which don't support flash, such as iPhone. I'd also like to have valid html5. The issue I see is that in html5, object doesn't support the classid attribute anymore, but this would be required for a user to get flash if they don't have it but want it.
It seems my options are to accept invalid html5 but not have the flash work properly, or have the classid and not have valid html5.
I'm using JWPlayer to serve an html5 video with a flash fallback.I'd also like to have an image fallback if there is neither html5 nor flash support but I can't see how to do this.
My code is as follows:
modes: [
{ type: "html5", },
{ type: "flash", src="http://www.mysite.com/jwplayer/player.swf"}
],

I'm doing Html5 video play on my project with flash fallback (if it doesn't support html5). But both players are loaded if browser supports both.
<video controls="controls" preload="auto" poster="image.url" >
<source src="video.url" type="video/ogg" />
<source src="video.url" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'/>

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 Replieshow to connect Flash to a server Using Sockets connection using in AS3.
View 16 RepliesI'm able to connect, able to send a message from HTML 5 to the AIR socket server and have the server see that there is an inbound message and even see that there are more or less bytes available based on the size of the message, but am unable to see the content of the message sent through. I'm just trying to send one-way text communication via sockets from HTML 5 to an AIR app. Why I can't see the actual content of the message? I'll attach my AS3/AIR (Flash Pro CS5) code and my HTML/JS code.
View 1 RepliesI dont know a lot about html5 but is this expetced to compete with Flash/AS3 with regards to game making, data connection etc? It hard to image OOP with html as some games take thousands of lines to do.
View 2 RepliesThis is driving me nuts and because it's a combination of various technologies together I have a hard time tracking the problem. I wrote a tiny HTTP server that serves .flv files; these flv files are encoded on the spot. The flv files are encoded with adobe's screencodec (I started with libflv but that was too buggy so I ended up implementing my own flv encoder). For the problem below it doesn't matter which codec I use or if I serve plain flv files instead of on-the-spot generated ones (the problem also occurs if I just send 12 h264 encoded files).
I also have a swf that I coded in as3. The as3 opens 12 connections to my server and requests 12 different flv's and just displays them as 12 different videos on the page. I tested the setup with Firefox and chrome and am using the latest flash client (version 10). The HTTP server is pseudo streaming those files; e.g. it tells the client the file is of mime type video/x-flv, tells the filesize is 2GB and just starts streaming. For sake of completeness here's a header it generates:

So, we want to move out from Air (Adobe stopping support and really bad implementation for the sqlite api, among other things). I want to make 3 things:
Connect with a flash (not web) application to a local mysql database.
Connect with a falsh (not web) application to a remote mysql database.
Connect with a flash (web) application with a remote mysql database.

if you can connect with socket wit mysql server, why use a web server (for example with php) to connect like a inter connectioN? why not connnect directly? I have done this a lot of times, using AMFPHP for example, but wouldn't be faster going directly? In the case of accessing local machine, it will be a more simple deploy application that only require the flash application + mysql server, not need to also instal a web server.
On my network I have a couple of pc's all running a bespoke server which will return the username of the person logged in when queried.I have the following piece of code.
private function LoopAndList():void
{
var loopSocket:Socket;
var fourthOctet:Number = 6;
[code]....
Now when this runs it doesn't work as I first thought. The iterations go though. the fourthOctet value is decremented. But somethinjg strange happens. You will notice in the above code that I have a hardcoded IP address in the loop. I have put this there to ensure that there is always a valid connection. So am aware it will always be connecting to 192.168.0.4.
But the connection only happens on the last connect call.
The ouput is:
192.168.0.6
Connecting to 192.168.0.6
192.168.0.5
Connecting to 192.168.0.5

I want to open a connection back to the server using Flex so I can stream chat messages to the Flex front-end. How do I do this and does Flex enforce any same-origin restrictions on ports or subdomains?
View 1 RepliesI've written a basic FTP client to allow me to upload files through the browser without using the FileReference.upload() func (because it's damn slow). I've got all the socket logic worked out and it works for one upload. When the upload is completed, the FTP data socket is closed by the socket.close() func which triggers a response from the command socket and starts the whole process over again. This logic works perfectly on my Mac in both Safari and FF.
I can upload files and cancel uploads and it all works as I want. When I test it on Windows (IE 8, FF 3.5, Safari 4 on WinXP and Win7) it is busted. I've tracked down the problem to the fact that on Windows, the socket.close() function is not causing the server to close the connection. I don't know if this is because it's not sending a proper command or what... but that's where it's at.
I'm just trying to understand how once HTML5 enters the picture, the current concerns about browser incompatibility and other issues go away? Wouldn't HTML5 simply add another set of browsers to the large list of current browsers that the application must target?
That is, assuming the enterprise web app requires one of these new HTML5 features (e.g. playing audio and/or video, integrating SVG or vector graphics, etc.). If such a feature isn't critical then graceful degradation may be acceptable and then my question is moot.
But for those apps that require one of these new HTML5 features, are you planning to support older browsers, or expecting it's acceptable to restrict to HTML5 browsers because the enterprise in question has made one of them their new corporate standard (or other scenario, etc.)?
I found this awesome example: [URL], or an HTML5 WebSocket echo server in Jetty, and I love it's simplicity. However, the web app I am developing will require a bit more cross-browser compatibility, so I tried to use: [URL] as a Flash fallback. The problem: I need to serve some XML file on port 843 for Flash. Now I am new to both Flash and Jetty, and would like to figure out how to accomplish this. I have used HTML5 WebSockets before in PHP, Python, and Ruby, and I have the echo server working perfectly on my Mac, but now I need to configure Jetty to send the file.
View 2 RepliesI'm using VideoJs to handle my HTML5 video needs, using a single M4V. I needed a playlist, and I'm able to change it's source easily using JS (in my case, jQuery). However, I'm not able to pass these changes along to the flash fallback (which is achieved via an object including flowplayer). How one might be able to dynamically change flowplayer's flashvars, and reload the object?
View 1 RepliesI'm trying to add mediaelement.js to my site to present a single player for any MP3 link on a particular page. The design is working fine for IE 9 and Chrome 11 (which have HTML5 MP3 support), but it has an issue with the flash fallback on Opera 11 and FireFox 4. Clicking any MP3 link on the page uses the .setSrc() method of media element player to change the source of the player, but in Opera and FF, the first time this method is called, it returns error "this.media.setSrc is not a function". Any call to the function after that works fine.
Another issue is after the element containing the player is hidden "display:none" and then displayed again, calling the .pause() function will produce error "this.pluginApi.pauseMedia is not a function". After that error is thrown, subsequent calls work fine until the element is hidden and displayed again.

I have the following code to display the swf object on the page. It works well in all browsers. However, if shockwave flash turned off in Firefox, it won't fallback into image and show bunch of characters instead looking like "CWS..." All other browsers fallback to the image. I verified that we serve application/x-shockwave-flash MIME type on our server.

Its showing me connecting ... Status is not getting update like: "Connection Failed" or "Connection Success". how to use the above information in this app,
I am not any kind of network programming pro, but it happened that I have faced necessity to develop socket-server on php (no way for using Java) for flash multiplayer browser-game (standard features like locations, team battles, etc).
The main problem is that TCP is point-to-point protocol and it completely occupies given port.Of course it is possible to create some kind of queue, which will manage connections to the socket, but this solution doesn't seems to be the fittest one.
It seems to me that using interval of "fair" ports (from 2000 to 2200, for example) is more fitting solution, because one request may take a lot of time to execute and players won't be happy to wait in queue.
But how can I implement this "port inteval" strategy?The solutions that I see are:
launcing php-script per every port (he-he, 2 hundreds of launched scripts!);somehow forking the initial process to new processes (2 hundreds of processed? Not nice too), one for every port;additional while-loop, which listens all the ports (looks very bad);using threading or something like that (the problem is that php is single-threaded, as far as I know; pcntl?).But somehow I don't like any of them, or at least don't know how to implement them in the best possible way.
What is the best existing strategy to handle multiple requests from multiple users per time unit without delays, and how to implement this strategy in php? We have our own Debian-server, so it is possible to use any required php extensions.
For example, if we are trying to develop chat application, we need some sort of fixed (I mean persistent) connections for each user. For example, we have 80 users in chat, and then one of them posted a message, which server tries to handle and send to all other connected users, also putting an entry to the history file or something like that.
In this situation polling server for new messages every 10 seconds from each of 80 users is craziness, so the need in persistent connection gets obvious.But I don't know what is the best way to implement something like this, considering that not all requests are handled instanlty.
I was trying to write a stress tester for my own protocol when I stumbled up on this problem.Anytime I create more than 4 connections from one PC Flash denies to receive anymore messages from the server although I'm still able to connect, and write messages.

View 1 RepliesIn my application I'm using a custom embedded font for English (Helvetica New) which does not contain characters (glyphs) for chinese unicode range. In the application, wherver chinese characters are avaiable they are not displayed (suppressed) since they are missing in the custom embedded font. How can I make the flash player to use a fallback system font for the missing characters? And the fallback should be for the missing characters alone. For the Engligh characters it should use the embedded font.
View 1 RepliesI have two (+) systems on a local network running an AIR application that need to send/receive updated positions and other events between each other. I'm currently using an AIR-based socket server one of the instances. The AMF and strong typing works great. What doesn't, however, is the syncing between clients.
In my example below, clientA is trying to send an AMF packet to clientB. The SOCKET_DATA events fire off as expected on the server, in sync with the mouse, however the data that clientB receives very quickly gets out of sync and events are lost.
It's fine if an occasional event gets dropped, however I need to know the most recent SOCKET_DATA event has the latest data. Instead, it just contains increasingly older data.
Code Snippets:
clientA writeObject: (on MOUSE_MOVE to test large number of events)
protected function stage_mouseMoveHandler ( pEvent : MouseEvent ) : void
