As a first step, do a port update to get all new packages:

port selfupdate

Step 2:

sudo port install asterisk

[This is a long process, it will start installing many dependancy packages]

Possible errors you can see:

1) Image error: /opt/local/bin/a2p is being used by the active perl5.8 port.  Please deactivate this port first, or use ‘port -f activate perl5′ to force the activation.

Solution: Check all perl version installed using the given command:

sudo port installed | grep perl

Uninstall old perl version will solve this problem.

eg: port uninstall perl5 @5.8.9_0

sudo port uninstall   perl5.8 @5.8.9_3

Also if you can run an update outdate package command, this will be alos helpful:

sudo port upgrade outdated

Continue again the command: sudo port install asterisk

2) Error: Target org.macports.configure returned: configure failure: shell command failed (see log for details).

portaudio failed to install.

Solution: Download port audio files from portaudio website.  Replace the source files of portaudio local folded  (where the error is located) and Manually install it using the following commands

sudo /usr/bin/make -j2 -w all
sudo /usr/bin/make install

After installation, link this portaudio with port installation using the following command:

port -f activate portaudio

Continue running this command: sudo port install asterisk

3) When installing Asterisk, you may get another error:

For a undefined variable: snmp/agent.c:830: error: ‘RONLY’ undeclared

Solution: Find the file snmp/agent.c and add #define RONLY 1

If Asterisk still fail to install, download the package file from asterisk website and install manually.

Before compiling this, edit makeopts file and update the line:

change “CONFIG_LDFLAGS=” to “CONFIG_LDFLAGS= /usr/lib/bundle1.o

Good luck

A normal Fan page of Facebook would like this:

https://www.facebook.com/apps/application.php?id=xxxxxxxxxx&sk=app_XXXXXX

This Url will call your domain, say example.com inside the iframe to load the page.

Each time the iframe is loaded, Facebook do a POST to this iframe URL with some data which we can use to identify the status of the user, eg, whether the user already liked this page, or any other parameter is passed through the fan page url.

Facebook keep app_data variable for developers to pass additional parameters to your iframe page.

eg: https://www.facebook.com/apps/application.php?id=xxxxxxxxxx&sk=app_XXXXXX&app_data=mydata

To retrieve this information, in PHP, use can use the following code:

<?php

if(isset($_REQUEST["signed_request"]))
{

$signed_request = $_REQUEST["signed_request"];
// $_POST also work, but better with $_REQUEST

list($encoded_sig, $payload) = explode(‘.’, $signed_request, 2);

$data = json_decode(base64_decode(strtr($payload, ‘-_’, ‘+/’)), true);

if(isset($data['app_data']))
{
$mydata = $data['app_data']; //here you can get the value you passed
}
}

?>

Two months ago, I published a jQuery plugin to record audio from browser (without any Media server) called jRecorder

I got many responses and requests to maintain the code with new enhancements and some bug fixes.

Based on that, a new version (1.1) is released which has the capability to preview the recorded audio before sending to the server.

See the example implementation and documentation here.

Also I made this source open and available for anybody to develop at: https://github.com/sythoos/jRecorder/

Thanks

Thanks CrosByMichaela for sharing this.

Air 3 has many support for mobile development. For example, it has now support of iPhone application background running features such as play audio, access internet, use voice service, and location based services.

Flash build iPhone profile xml file now supports properties like:

    <key>UIDeviceFamily</key>
         <array>
                    <string>1</string>
                    <string>2</string>
          </array>
     <key>UIBackgroundModes</key>
     <array>
                <string>audio</string>
     </array>
     <key>UIRequiresPersistentWiFi</key>
     <string>YES</string>

To Record voice from web we need the following thing:

1) A flash media server (eg: Adobe Media Server [paid] or Red 5 [free])

2) Java6

3) Webserver (eg, Apache, PHP)

4) A flash client app to record voice

The one I used
=========

We used Red 5 Server, because it is FREE and Open Source

We can proceed with our Apache + PHP

Flash Recorder APP from AVChat (They have Free Trial recorder for 30 days and the Full version costs around £50)

Installation
=======

Install Java 6 (find the correct build based on 64 bit or 32 bit processor)

install RED 5 (Download from http://code.google.com/p/red5/)

Run RED 5 and test the installation

Open a browser and type: http://127.0.0.1:5080/

If the installation is success, you can see the RED5 page

Try to install some demo app and try those demos

You need a Browser with Flash support to test the demos (Allow the security options)

Voice Recorder Client App
=================
You can many FREE recording app over internet. Even you can get the Action Script for Voice recording and you can create your-own Flash recorder if you know Flash

A better voice recorder app can be found at http://flvar.com/ which has PHP and ASP support where you can save/manipulate the recorded file

The AVChat App
===========

Download the chat app from the site http://flvar.com/

There are two sets of folders, on for red5 and one for web server.

Put the red5 projects in your webapps folder of RED5 server root

When you download the app, you’ll get a license key. Enter this key to the property file inside the red5 server app.

Put the web server folder in your apache web root

Open avc_settings.php and update the path of RED5 with your RED5 server path (see the example in the document)

Try accessing this project with your web browser, if you can see the flash player , it means your web app works fine

Try start recording, and if you can record, which means your RED5 server configuration is fine

Stop recording and click “Save”

Check for the recorded flv file in the RED5 stream folder.

This “Save” action trigger save_audio_to_db.php where we get details of the recorded stream and we can use PHP to manipulate that.

For example, to move the flv file into webserver root, or use FFMPEG to convert the FLV format to WAV or MP3 etc

Enjoy Voice Recording
