I need to communicate to the server in real-time. I can't let clients write to remote shared objects so I have to forward their requests to the server which checks if the data is valid and then writes it to a remote shared object. Should I use NetConnection.call() to forward clients' request to the server or is there something faster than that?

View 1 RepliesI want to pass a rest in a netconnection call, something like this:
public function requestData(service : String, ...params) : void
{
nc.call(service, params);
}
this doesn't work since the call is expecting each parameter to be separated by commas, like:
nc.call(service, params[0], params[1], params[2]);
I've read some posts about apply, but I can't find a solution for this specific case.

I'm recording mic audio into a byte array as a WAV file and uploading it with NetConnection.call(amf.service,responder,bytearray ); It works fine but the files are very large and take a long time to upload. Is there any way to get the upload progress? I can't find anything in AS3 docs or on the web.
View 5 RepliesI am now developing a Flex application in which I need to control each pixel of my control of Flex. I want to calculate that how width and how height of some text used in my control and do some layout stuff.After some searching I find that the only way to draw text in Flex is to use something like TextField. So, I use TextField to display text and try to get the width and height of the text through:
textfiled.getLineMetrics(0).width/.height;
But the real textfield is much more bigger than this, so I do:
textfield.width = textfiled.getLineMetrics(0).width;
textfield.height = textfiled.getLineMetrics(0).height;
But, the textfield get part not displayed, and I am surprised by this effect. I know there should be a 2-pixel gutter around the text, but what the remain space? Why nearly 20% part of the text height/width are not displayed?
how can I get a real drawText call in Flex, I mean something like Windows's drawText method...
I'm writing a real-time app using a Flex/Flash client and my own server running on Linux.
I'd like to be able to send data from the Flex client in real time (in response to user actions). I've tried the following methods:
flash.net.NetConnection.call()
flash.net.sendToURL()
flash.net.Socket.write() followed by flash.net.Socket.flush()
[Code].....
The second nc.call() above won't send data to the server until the ACK for the first call has been recieved. I'd like to be able to send data immediately without waiting for that ACK.
If the round-trip time to the server is long (e.g. 300ms) I can only send data to the server 3 times a second. Ideally I'd like to be able to send data up to 30 times per second, but this is only possible with a RTT of around 30ms at the moment.
It doesn't matter if the server itself gets the data 300ms late - I realise I can't beat the speed of light.
Is there any way to get the Flash Player to send data without waiting for an ACK? In other environments this is done by setting the TCP_NODELAY flag on the socket but it seems I don't have that level of control in Flash/Flex.
Update: I think I may have stumbled on a workaround for this. I think the Flash Player tries to get the host browser to give it a separate TCP connection for each NetConnection object, subject to the connection limit for each browser, e.g. 2 for IE. The connection limit can be got around by using sub-domains (haven't tried this yet) so hopefully it should be possible to get closer to real-time behaviour by using a pool of NetConnections.

I am currently building a Flex application with a PHP backend.

I'm currently using the Graphics library to draw bands of color across an image (bitmap).So, I draw a square of colored bands, and mask it with the bitmap image. Unfortunately, when I use a mask (or even set the blend mode to .LAYER, OR use a shader filter) the FPS drops to un-usable levels.Is there some way that I can draw the bitmap shape I want without killing the FPS? I was thinking that I could like, draw the bitmap on top of the sqaure of Graphics, and then make a certain color transparent.

Is it possible to play the video (mp4) in real time using some flash player? What I mean by in real-time is that player would receive data on the fly, not from alredy saved file but e.g. php script (which sends appropriate content-type header) THAT IS DOWNLOADING AND 'ECHO-ing' THE FILE AT THE TIME PLAYER PLAYS IT - like e.g. some kind of live stream.

View 6 RepliesI have a C executable (named myprogram). When I run it by ./myprogram I get some output statements on the standard output of my Linux shell. I used run.php to get access to whatever is being printed to the standard output:
#run.php
<?php
$output = shell_exec('./myprogram');
echo $output;
?>
Then I called an HTTPService having id="service" to access this run.php file and I also set the text attribute of a TextArea to {service.lastResult}. When I run my Flex app, the interface kind of halts for a moment and then the TextArea displays all the 20 lines at once. But if program is run from Linux shell they appear one by one. Is there a way by which I can display a line as soon as it gets printed to standard output? This will then make the TextArea show the output in real time.
Or is Flex unable to do this? Rather how can a PHP program achieve such effect i.e. showing, whatever is being printed on standard output, concurrently in the browser in real time? Myprogram outputs 20 lines each after some microseconds. I want only the first line of standard output to appear in TextArea of Flex or in the browser (but in real time) while the program may then continue running the program.
I have a Flex/AIR application communicating with a PHP server application. Recently my client requested real-time-like connectivity between the applications to replace what we currently have; refresh buttons which have to be clicked to refresh data.So effectively the server needs to push data to the client when something changes. I can write the code that detects when something changes, but I'm not sure about the push side of things.

View 9 RepliesI'm looking to create something within Flash that I've not yet seen done.It will be a shared, real-time interactive session. What I want to know is, is it possible to create an individual, private session within Flash that is synchronized between two or more computers? I am doing this for the medical profession, but I can also see this would have benefits in the gaming community as well. I'm trying to create something that two specific users can interactively share in real time.
For example,a coloring book.Two players,or as many as you want, log in together and share a private coloring session. They will be able to interactively see anything that the other person is coloring in real time.The other people would also be able to color and let everyone else see their work.
I want to do a flash that changes based on the time of day. For example to load right .swf on container MC at the right time of the day.
View 1 RepliesIm trying to create a real time multiplayer game similar to "Stick Arena". Ive already created a nio java server which works wonderfully.

When the game is tested ona single computer everything gets sent without any significant delay (1ms~). Whats wrong?
View 6 RepliesI'm working on a simple real time graph. The data is polled every 50ms, and each poll translates to a line one pixel wide, (data_point) pixels high. The graph scrolls such that new data is on the right, and the oldest values eventually fall off the left.
My solution is embarassingly brute-force, in that I just use theMC.graphics.clear() and a loop of lineTo()s for every graph refresh. While this displays correctly (and I can control the refresh rate to mitigate the CPU burn), it should be painfully evident why I want to move away from this method.
I want to programatically scroll or pan the entire graph one pixel to the left (and drop the leftmost line), and then just draw one new line on the right, but I can't figure out where to start. Assuming such a thing is possible in AS3, would someone be so kind as to point me in the right direction?

View 1 RepliesFlash can use the RTMP protocol to exchange data between a server and a client. How do you typically access this functionality in AS2 or AS3/Flex? For example to use sockets you use the XMLSocket (AS2) or Socket (AS3) classes. Does the server-side RTMP software use Sockets under the covers? or is it HTTP with tunneling?
The Real-Time Messaging Protocol (RTMP) was designed for high-performance transmission of audio, video, and data between Adobe Flash and a server. RTMP is now available as an open specification to create products and technology that enable delivery of video, audio, and data in the open AMF, SWF, FLV, and F4V formats compatible with Adobe Flash Player.
I'm trying to build a system that live-streams video and audio captured by android phones. Video and auido are captured on the android side using MediaRecorder, and then pushed directly to a server written in python. Clients should access this live feed using their browser, so the I implemented the streaming part of the system using flash. Right now both video and audio content appear on the client side, but the problem is that they are out of sync. I'm sure this is caused by wrong timestamp values in flash (currently I increment ts by 60ms for a frame of video, but clearly this value should be variable).
The audio is encoded into amr on the android phone, so I know exactly each frame of amr is 20ms. However, this is not the case with video, which is encoded into H.264. To synchronized them together, I would have to know exactly how many millisecs each frame of H.264 lasts, so that I can timestamp them later when delivering content using flash. My question is is this kind of information available in NAL units of H.264?
