I have to implement AEC in Flex video conferencing application. I know that it can not be done directly in Flash. I'm thinking to write a native application or library that will do AEC outside Flex.
As far I know Adobe Connect Pro is using some external library that do AEC. I'd like to follow this direction and do something similiar.
There comes two possibilities in my mind:
1) Independend custom AEC filter.
The custom AEC filter will be run in the background and will be processing all data from microphone and sound card and doing AEC. The echo signal will be the data that is to be played but delayed in a temporary buffer, something like this: aec(input, delayed_input, output).
I don't know if it work, because Flash microphone input doesn't know about my custom input and the same with the speakers. But how it is done in WinXP/Vista that have AEC at the system level?
2) AEC filter interacting with Flex's NativeProcess.
The filter will be run by NativeProcess. Flex app will pass microphone sound, received remote voice to the filter and return voice with echo removed and then Flex will output this to the speakers. Will it be correct?
If the 2) method is OK then I have following questions:
I will start with Speex's AEC so in what format should be the data pased from Flex? If I choose Flex Speex codec for sound compression can I pass it directly to the speex library? Will be the performance OK? Calling NativeProcess library every sound frame buffer can be time consuming I think. Why there is no AEC implementation in AS3 that can be used directly from Flash? As far I know to do AEC you must have echo data and microphone data (in Flash 10 there is direct access to the microphone). There is definetly something that is stopping doing it like this but I don't know what it is yet :) Is there some free AEC implementation or a DSP library with in except Speex's that I can use?
The selected text in white is really not good visible selected.Why flash does not suppor that?http://lionhead.nl/voorbeelden/flash_selected_text_error/Flash%20text% 20error.htmlHow come there is nowhere to set anything to make this work properly. Like in html does this automatic?Adobe is this a bug or not for this?
So I have a music clip that is looping in my timeline. The frames for this clip extends to frame 2966. However, when I want to fade out the clip by going to the properties of the music clip and selecting custom for the effect, clicking on edit sound envelope it only lets me scroll to frame 2465 and no further....So what the heck am I doing wrong or is this a bug in flash?
I have a DataGrid of objects, and I want to modally edit them; pop up a dialog, change the item, and if the user clicks "Ok", save the changes back to the original item, and if they click "Cancel", do nothing. It seems obvious that if I simply pass in a reference to the original object and change it using data bindings to the fields in the edit form, I won't be able to cancel my edits. How can I support that capability?
I am working with videoChat application.Videos are good to display to all.But the voice getting problem.If I speek using microphone(included with headphone set)the voice is echoed.How to cancell it.Presently is there any solution to resolve it, bcz since this is a bug as reported.Any third party softwares are available to work with echo.
Im still new in using as2 as well as as3 so Im begging for your kind consideration on how to solve my problem. I made a php file which outputs an XML file. Here is the code xml file "load.xml".
echo ("&response=$sent"); Is there anyway to look for only the echo in flash. not the rest of the vars from a php file??? something like loadvars("my.php?&response", GET);?
HI have a php setup to echo an XML document.In actionscript, I'm trying to send the artist's name to PHP, PHP will pull the artist info from SQL and echo out in XML for flash.Is there something wrong with my Flash Script? The artistName variable will contain a string with an artist's name...just an FYI, but like I said, it returns back with information, but not in XML format.[code]
i have a php script that print with echo this: '&string="tom,dick,harry"' and i need to put the "tom,dick,harry" in an actionscript string, that i have to split in an array. I'm having problems reading the php output, i'm using the URLLoader and TheURLVariables Classes in this way
My goal is to simply echo $_POST['imageVar']; back with content headers as a quick and dirty means to "export" an image from a flash application. I saw an example of this as follows, but it does not work with my php version/config:
if (isset($GLOBALS["HTTP_RAW_POST_DATA"])) { // get bytearray
Has anyone experienced an echo when using Google Chrome? It seems to only happen if the sound begins playing while other assets are loading, and while that may seem like an easy fix I want the sound playing during the loading sequence. I've tested playing the sound on a key stroke after all of the other assets have loaded and it does not play twice. This behaviour does not occur in Firefox.
I am trying to make this form work, but I think I am just missing a little bit.
I have the following AS: var send_lv = new LoadVars(); var result_lv:LoadVars = new LoadVars();
[Code]......
My php works fine, except I think I need to change the echo, but I don't know what to. This is what I have now: echo "&Status=Your quote request has been sent.";
I am trying to do a simple php echo to flash. I want to do a loadvars.load("tomyscript.php",0,"POST"); and echo back an address....such as echo "[URL].. in php and I want flash to be able to read it. I have sound very little on echo back to flash, maybe I am typing the wrong keywords. I have done this before, but this was my code:
I am not sure why that works and my other echo doesnt.I tried using that script for my idea too and it didnt work. If someone can clear this up for me that would be great, so I can understand why it's not working and what it's doing.
I am trying to query a sql database and echo the image into xml so I can view the queried image in flash.
I already know how to query and echo the image url from the database.
This is the code:
//The database is already queried at this point. echo "<?xml version="1.01"?> "; echo "<content>
[Code].....
The echoed xml in the first code produces a url link that contains a link to an image in the database. The flash is supposed to display the image on a flash movie clip call movieobject. I am having problem getting the image displayed in flash.
I'm working on a project that requires me to communicate with a database. I am using PHP and mySQL with flash on the front end. My problem is that in order get variables back from PHP I have to double them or atleast double the first 2. So this doesn't work: $loginResult .= " " ; $loginResult .= "wasSuccessful=" . $wasSuccesful . "&" ; echo $loginResult ;
But this does: $loginResult .= " " ; $loginResult .= "wasSuccessful=" . $wasSuccesful . "&" ; $loginResult .= "wasSuccessful=" . $wasSuccesful . "&" ; echo $loginResult ; And I only get one result.
ActionScript 3 can send UDP packets via flash.net.DatagramSocket. Is their any way to send an ICMP packet? I'd also like to set the TTL flag so I can implement traceroute in an SWF.
I can't paste the example link - but the source I am referring to below is the Sound class definition in the ActionScript documentation on [URL] when I duplicate the upOctave example on extract, I get echo. I want to play the sounds not only "up and octave" but twice as fast - is there a good way to double the playback speed of a sound file?
I'm trying to upload an image file to another server and load the image into my flash application. I've modified crossdomain.xml as to allow the php to do the uploading to the other server.
I am trying to change the text color when getting echo text from php: Have defined in MC a dynamic field: EmailStatus "Submit" back command from php: Code: lv.onLoad = function() { _root.pages.Mail.EmailStatus = this.msg; };
And echo from PHP PHP Code: echo "&msg=Your mail was sent"; How can I make "Your mail was sent" another color instead of already chosen color for that field?
I am using FMS for live streaming. Am using Flash to publish live video, I have one to one live streaming where I can see other end user live video and other end person can see mine live video. So one input stream going to server and one out put stream coming back. The problem what I was getting is sound is getting echo i.e., Repetitive sound getting.
I'm using Flash Media Server to create a 1:1 video chat. The problem I'm having is that when I use my apple cinema display I get horrible Echoing, even with the reduce echo box checked. If I don't use my cinema everything works fine with the built in macbook mic. I have to believe there is a setting as I can use iChat, Adobe Connect, WebEx, Skype all with my apple cinema and not have this MIC echoing issue.
Our Current Settings: Audio var options:MicrophoneEnhancedOptions = new MicrophoneEnhancedOptions(); options.mode = MicrophoneEnhancedMode.FULL_DUPLEX; options.echoPath = 256; options.nonLinearProcessing = true; [Code] .....
I am creating an audio communication application. In that two users are able to communicate. But the problem is that some time in audio I am facing an echo problem.
