Configure PostgreSQL and phpPgAdmin in WAMP

2011-09-05T09:09:00.000-07:00

As i told earlier am trying to switch to Flex , i am trying to learn connection between PHP and Flex. When searched i got a excellent tutorial . But the problem is that it uses PostgreSQL. As i don't have any prior experience in PostgreSQL i try to install it in my Windows 7 and configure it in WAMP . I got different errors and spend almost two days in searching and using different methods . Atlast i got it right. I will try to figure out the steps i have done.
Am using

PostgreSQL 9.1
WAMP Server 2.0e
phpPgAdmin 5.0.2

WAMP consists

1. Apache Version :2.2.17
2. PHP Version :5.3.5
3. MySQL Version :5.5.8

First install PostgreSQL , no need to install additional plugins like phpPgAdmin.
Install WAMP server where ever you need.
Download PhpPgAdmin and unzip it to WWW folder in WAMP installation.

At this point if you try to access the http://localhost/phpPgAdmin/ you may get this error.

Your PHP installation does not support PostgreSQL. You need to recompile PHP using the --with-pgsql configure option.

This is because you need to enable two extensions.

php_pgsql
php_pdo_pgsql

After enabling this extensions you may not see installed extension in phpinfo. if you check the Apache error log you see this error

PHP Warning:  PHP Startup: Unable to load dynamic library 
'D:/wamp/bin/php/php5.3.5/ext/php_pdo_oci.dll' - The specified module 
could not be found.\r\n in Unknown on line 0

 Warning:  PHP Startup: Unable to load dynamic library
 'D:/wamp/bin/php/php5.3.5/ext/php_pdo_oci.dll' - The specified module 
could not be found. in Unknown on line 0
PHP Warning:  PHP Startup: Unable to load dynamic library 
'D:/wamp/bin/php/php5.3.5/ext/php_pdo_pgsql.dll' - The specified module 
could not be found.\r\n in Unknown on line 0
Warning:  PHP Startup: Unable to load dynamic library
 'D:/wamp/bin/php/php5.3.5/ext/php_pdo_pgsql.dll' - The specified module

PHP Warning:  PHP Startup: Unable to load dynamic library 
'D:/wamp/bin/php/php5.3.5/ext/php_pgsql.dll' - The specified module 
could not be found.\r\n in Unknown on line 0
Warning:  PHP Startup: Unable to load dynamic library
 'D:/wamp/bin/php/php5.3.5/ext/php_pgsql.dll' - The specified module 
could not be found

To correct this error you need to copy libpq.dll from wamp\bin\php\php5.3.5 to wamp\bin\apache\Apache2.2.17\bin . Then try to enable PHP extension and check apache error log you will not see the error . And pgsql will be shown in Loaded extensions in http://localhost/.

Now try this http://localhost/phpPgAdmin/ and you will see the PostgreSQL server. Select the PostgreSQL and login using the deafult user "postgres" and the password you given when PostgreSQL installed. You may not able to login. It may say "Login disallowed for security reasons." . You need to set some parameters in \www\phpPgAdmin\conf\
find

$conf['extra_login_security'] = true;

and change

$conf['extra_login_security'] = false;

and find

$conf['owned_only'] = false;

and change it to

$conf['owned_only'] = true;

Now you can login to PostgreSQL using phpPgAdmin and work on it. You can now create database and work on it. But If you tried to export the database you will get another error

Export error: Failed to execute pg_dump (given path in your conf/config.inc.php : /usr/bin/pg_dump). Please, fix this path in your configuration and relog.

This is because you did not set the path correctly . You need to change two other parameters in config.inc.php

$conf['servers'][0]['pg_dump_path'] = '/usr/bin/pg_dump';
$conf['servers'][0]['pg_dumpall_path'] = '/usr/bin/pg_dumpall';

change these params to

 $conf['servers'][0]['pg_dump_path'] = 'C:\Program Files\PostgreSQL\9.1\bin\pg_dump.exe';
 $conf['servers'][0]['pg_dumpall_path'] = 'C:\Program Files\PostgreSQL\9.1\bin\pg_dumpall.exe';

check your PostgreSQL installation directory. Now you can export the database.

Hope this post helps to configure PostgreSQL and phpPgAdmin successfully.

Connecting Flex 4 with AMFPHP

2011-08-31T09:11:00.000-07:00

These days am missing this blog coz am busy with learning Flex. When i tried to connect with AMFPHP i can't find anything useful. Most of them were vague .Using the default data connectivity in Flash Builder am more confused and it's code looks complex . Atlast i found someone helpfull from adobe forum.

When i tried to implement it , it shows nothing and missing some files. When i checked the PHP file, though am not good in PHP , i found there is also something also missing. I tried and searched and corrected the files.
Here is the MXML code:


	
					import flash.events.MouseEvent;
			import mx.controls.Alert;
			import mx.events.FlexEvent;
			import mx.rpc.events.FaultEvent;
			import mx.rpc.events.ResultEvent;
			protected function	getAllEmployees_resultHandler(event:ResultEvent):void	
			{
				dataGrid.dataProvider=event.result;
			}
			protected function	getAllEmployeesByID_resultHandler(event:ResultEvent):void
			{
				dataGrid.dataProvider=event.result;
			}
			protected function	createEmployees_resultHandler(event:ResultEvent):void
			{
				Alert.show("inserted with ID="+event.result);
				EmpService.getAllEmployees();
			}
			protected function EmpService_faultHandler(event:FaultEvent):void	
			{
				trace(event.fault.faultDetail);
			}
			protected function datagrid1_creationCompleteHandler(event:FlexEvent):void
			{
				EmpService.getAllEmployees();
			}		
			protected function Insert_clickHandler(event:MouseEvent):void	
			{	
				var e:Employee = new Employee();
				e.first_name = fname.text;
				e.last_name = lname.text;
				e.hire_date = hdate.text;
				e.birth_date = bdate.text;
				e.gender = gender.text;
				e.emp_no = parseInt(empno.text);
				EmpService.createEmployees(e);
			}
			protected function search_clickHandler(event:MouseEvent):void	
			{	
				EmpService.getEmployeesByID(parseInt(stext.text));	
			}
			protected function button1_clickHandler(event:MouseEvent):void
			{
				EmpService.getAllEmployees();
			}
		]]>

This is the PHP service class which needed to be placed in the /services folder both in AMFPHP1.9 and 2.0 versions.

<?php
  include('Employee.php');
  //amfphp1.9
  class EmployeesService
  {
      var $username = "root";
      var $password = "";
      var $server = "localhost";   
      var $port = "3306";
      var $databasename = "fb_tutorial_db";    
      var $tablename = "employees";
      var $connection;
      public function __construct()
      {
          $this->connection = mysqli_connect($this->server, $this->username, $this->password, $this->databasename, $this->port);
      }
      
      public function getAllEmployees()
      {
          $stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename");
          mysqli_stmt_execute($stmt);
          $rows = array();
		  $row = new Employee();
          mysqli_stmt_bind_result($stmt, $row->emp_no, $row->birth_date, $row->first_name, $row->last_name, $row->gender, $row->hire_date);
          while (mysqli_stmt_fetch($stmt)) {
              $rows[] = $row;
              $row = new Employee();
              mysqli_stmt_bind_result($stmt, $row->emp_no, $row->birth_date, $row->first_name, $row->last_name, $row->gender, $row->hire_date);
          }  
          mysqli_stmt_free_result($stmt);
          mysqli_close($this->connection);
          return $rows;
      }
      
      public function getEmployeesByID($itemID)
      {
          $stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename where emp_no=?");     
          mysqli_bind_param($stmt, 'i', $itemID);  
          mysqli_stmt_execute($stmt);
		  $row = new Employee();
          mysqli_stmt_bind_result($stmt, $row->emp_no, $row->birth_date, $row->first_name, $row->last_name, $row->gender, $row->hire_date);
          if (mysqli_stmt_fetch($stmt)) {
              return $row;
          } else {
              return null;
          }
      }
      
      public function createEmployees($item)
      {
          $stmt = mysqli_prepare($this->connection, "INSERT INTO $this->tablename (birth_date, first_name, last_name, gender, hire_date) VALUES (?, ?, ?, ?, ?)");  
          mysqli_stmt_bind_param($stmt, 'sssss', $item["birth_date"], $item["first_name"], $item["last_name"], $item["gender"], $item["hire_date"]);
          mysqli_stmt_execute($stmt);
          $autoid = mysqli_stmt_insert_id($stmt);
          mysqli_stmt_free_result($stmt);
          mysqli_close($this->connection);
          return $autoid;
      }
  }
?>

Here is the PHP Value Object Class

<?php
class Employee{
	public $emp_no;
	public $first_name;
	public $last_name;
	public $gender;
	public $hire_date;
	public $birth_date;
}
?>

For AMFPHP 2.0 edit the endpoint from http://localhost/amfphp/gateway.php to http://localhost/amfphp2/ (version AmfPHP 2.0 )
And need to change the createEmployees($item) function in EmployeeService.php to

  public function createEmployees($item)
      {
          $stmt = mysqli_prepare($this->connection, "INSERT INTO $this->tablename (birth_date, first_name, last_name, gender, hire_date) VALUES (?, ?, ?, ?, ?)");  
          mysqli_stmt_bind_param($stmt, 'sssss', $item->birth_date, $item->first_name, $item->last_name, $item->gender, $item->hire_date);
          mysqli_stmt_execute($stmt);
          $autoid = mysqli_stmt_insert_id($stmt);
          mysqli_stmt_free_result($stmt);
          mysqli_close($this->connection);
          return $autoid;
      }

I don't know the reason but it worked for me. But i think in 1.9 the object passed to PHP function is an array and in 2.0 it's an object of stdClass. That's why this change.

Font embedding in Flash cs5

2011-03-11T06:49:00.000-08:00

When i switched to Flash CS 5 am always confused with font embedding in Dynamic Textfield. It's different from CS4 and also not simple. So i am trying to list out the methods i used to embed fonts in flash CS

Method One
It's used to embed fonts for single or similar type of textfields. If the textfields were using same font and format this is effective. To do so first select the TextField and goto the properties panel.

select the embed button . It will open embed window. select the glyphs needed.

In this method any additional code is not needed.

Method Two
If you tried to embed same font with different textformat using the above method , most probably the format will not be applied. To solve this the subset of the fonts should be embedded and need format textfield using TextFormat.

The code looks like this:

var format:TextFormat = new TextFormat();
format.font = "Helvetica";
format.bold = true;

var format3:TextFormat = new TextFormat();
format3.font = "Helvetica";
format3.bold = true;
t2_txt.embedFonts=true;
t2_txt.defaultTextFormat = format;
t3_txt.defaultTextFormat = format3;

t1_txt.text = "Hello World 01 *";
t2_txt.text = "Hello World 01 *";
t3_txt.text = "Hello World 01 *";

Method Three
The third method of embeding font is to load from external swf file. In this method Fonts added as a subclass of Font class . The embed fonts must be export for Actionscript.

The fonts will be loaded to an external swf and it will be loaded in runtime. The exported class should registered using Font class.

import flash.text.Font;
Font.registerFont(Font1);

In main movie the code looks like this

import flash.display.Loader;

function onLoaded(e:Event):void
{
 var embeddedFonts:Array = Font.enumerateFonts(false);
 for (var i:Number = 0; i < embeddedFonts.length; i++)
 {
  var item:Font = embeddedFonts[i];
  trace("[" + i + "] name:" + item.fontName + ", style: " 
                     + item.fontStyle + ", type: " + item.fontType);
 }
 var t1_txt:TextField=new TextField();
 addChild(t1_txt);
 t1_txt.x=20;
 t1_txt.y=100;
 t1_txt.embedFonts = true;
 var format:TextFormat = new TextFormat();
 format.font = "Helvetica";
 format.bold = true;
 t1_txt.defaultTextFormat = format;
 t1_txt.text = "hello world 01 *";
 //
 var t2_txt:TextField=new TextField();
 addChild(t2_txt);
 t2_txt.x=20;
 t2_txt.y=200;
 t2_txt.embedFonts = true;
 var format2:TextFormat = new TextFormat();
 format2.font = "Helvetica Light";
 t2_txt.defaultTextFormat = format2;
 t2_txt.text = "hello world 01 *";
}

Any way textfields in stage are not working properly. I think the problem is it will instantiate before the font is loaded.

I have attached my source here. while embedding the glyphs, select the required ones. Otherwise it will affect the size of the movie.

These are not the complete list . It's not an expert opinion . And it's about Flash CS5 and not Flex . In Flex there is embed tag which is used to embed fonts. These are the methods used by myself for dynamic font embedding. Hope some people will contribute their experiances also to this.

Customizable XML based Flash image scroller

2011-02-25T20:56:00.000-08:00

I missed this blog for more than 2-3 months. It's been a long time since i have wrote something usefull .

So i created a image scroller using XML .This scroller uses TweenLite for tweening and it's simple to customise. You can add image with any size and can customize the number of images shown.
I have shared the source code here.

Requirements
1. Flash CS5
http://www.adobe.com/products/flash/

2. TweenLite AS3.0
http://blog.greensock.com/tweenlite/

It's possible to change the attributes through xml if you wanted .
Read the params from xml and add to the local variable inside the function onXmlLoadComplete .

//Total number of images :
private var total:Number = 0;

//Current item to be displayed;
private var currentId:Number = 0;

//The number of items to be shown ata a time:
private var itemsToShow:Number = 4;

Back in action

So am back with my new success/ failure. Hope the coming articles will help someone in the future.

And also now i am experimenting with Android also.

Adding proxy in YUM Fedora 13

2010-10-12T08:27:00.000-07:00

Recently i need a linux machine in my office for server . So i installed Fedora 13 and try to install mysql server using yum. But i can't complete it because yum is not connecting to internet. It's because of our proxy server.

Before 2 months i installed Fedora 12 and failed to install Mysql using yum.

I just searched for setting proxy in yum and got the answer for it. This is the solution,

1. open /etc/yum.conf

2. add proxy=http://proxyaddress:port

Voila :D , it works fine for me. Atlast my 3 months quest ends here . :P .

Perspective problem in Flash native 3D

2010-07-22T08:23:00.000-07:00

Nowadays am busy with some projects in flash using it's native 3D. In this post i like to share my experience with flash 3D. The native 3D in flash Player 10 is awesome. I used some flash coverflow and 3D picture gallery in project.

First it seems very easy but soon i found that resizing of the stage cause some problems in the 3D perspective. I searched everywhere and found some wonderfull thing.
Whenever we use 3D properties flash will automatically convert it to some bitmap and its in the 3D space. After that if we try to resize the stage and align the component according to the stage size flash projectioncenter will change . So we need to reset it by using the following code.

stage.addEventListener(Event.RESIZE,onSize);

private function onSize(e:Event) {
root.transform.perspectiveProjection.projectionCenter=new 
   Point(stage.stageWidth/2,stage.stageHeight/2);
}

Why i like to use Casalib

2010-04-20T23:23:00.000-07:00

I just started playing Actionscript 3.o. And I got some problem with Evnts. My code looks like something like this.

My movieClip Class is like this.

package{
import flash.display.MovieClip;
 import flash.events.Event;
 public class MC extends MovieClip {

  var val=1;
  var _o;
  public function MC() {
   _o=this;
   _o.addEventListener(Event.ENTER_FRAME,onLoop);
   }
  private function onLoop(e:Event) {
   trace(val);
   val++;
  }
 }
}

It's the code in the main.fla

b1_btn.addEventListener(MouseEvent.MOUSE_DOWN,clicked);
var m:MC=new MC();
addChild(m);

function clicked(e:MouseEvent) {
 removeChild(m);
 m=null;
}

The problem i get is with enterframe. After removing the Movieclip from the stage, enterframe don't stop it's working.
So i posted this in forums. It's the problem of garbage collection. Till now am playing with Actionscript 2.0 i never think about the garbage collection. The solution is to remove listeners manually or just use REMOVED_FROM_STAGE or REMOVED event.

So i have to change the MovieClip class to something like this.

package {
import flash.display.MovieClip; 
import flash.events.Event; 
public class Mextends MovieClip {
    var val=1;
    var _o;
   public function MC() {
      _o=this;
      _o.addEventListener(Event.ENTER_FRAME,onLoop,false,0,true);
      _o.addEventListener(Event.REMOVED,destroy);
    }
    private function destroy(e:Event) {
     _o.removeEventListener(Event.ENTER_FRAME,onLoop);
      _o.removeEventListener(Event.REMOVED,destroy);
    }
    private function onLoop(e:Event) {
    val++;
      trace(val);
    }
  }
}

This approach doesn't seem to me so good. So i searched in google and i get something more interesting .

It's casalib, an open source Actionscript Library for streamlining the development.

The most important thing interested me is the garbage collection using destroy() method. It will remove all events in the Movieclip.Then i just changed my code to some thing like this.

It's my MovieClip class

package {
  import org.casalib.display.CasaMovieClip;
 import flash.events.Event;
  public class MC extends CasaMovieClip {
    var val=1;
    var _o;
     public function MC() {
   _o=this;
   _o.addEventListener(Event.ENTER_FRAME,onLoop,false,0,true);
  }
  private function onLoop(e:Event) {
   trace(val);
   val++;
  
  }
 
 }
}

this is my code in Main.fla

b1_btn.addEventListener(MouseEvent.MOUSE_DOWN,clicked);
var m:MC=new MC();
addChild(m);
function clicked(e:MouseEvent) {
 m.destroy();
 m=null;
 trace(m);
}

And it works perfectly . Now am extensively using this library in my development. it's easy to remove nested movieclips and it's events.

External models in Papervision3D

2010-04-09T05:02:00.000-07:00

I think am taking a bit more interest in Actionscript 3.0 . Coz now am trying Papervision3D . The thing attracted me most is the

loading of external model to flash . So i searched google and got this book.

http://blog.papervision3d.org/2009/09/03/papervision3d-essentials/

I got what am looking for , in the free chapter . First i can't understand a word from that .Coz i have little

exposure in 3D. So i worked with my genius designer and after a a long struggle am able to load the external models to flash.

I decided to document the steps. For this you need these

1. Flash professional

2. Autodesk 3D studio

3. Papervision3D

http://blog.papervision3d.org/

4. Collada plugin

You can use 2 plugin's one is from here

http://sourceforge.net/projects/colladamaya/files/

and another from open collada

http://opencollada.org/download.html

better use opencollada as it is has less dependancies. The former one requires updating the VC and DirectX .

Download it from here

http://www.microsoft.com/downloads/details.aspx?familyid=2da43d38-db71-4c1b-bc6a-9b6652cd92a3

http://www.microsoft.com/downloads/details.aspx?familyid=200B2FD9-AE1A-4A14-984D-389C36F85647

While installing the collada plugin you may get errors when you open 3D max. Just try to reinstall the Vc and Directx again and again .This is why i insisit to use opencollada.

The 3D part

1. create a model like box in 3dStudio max. Don't forget to set x and y to 0.

2. Goto modify UvWmapping .

3. Open Material editor apply bitmap material

4. goto render settings , add diffuse map to it

5. Then save the map as png or jpg

6. and render the object

7. Save it in collada. Don't export it in Autodesk Collada format. Use opencollada or colladamax

The Flash Part .

1. Create a new Flash document

2. Add the document Class as Main

3. Copy the Main.as to the folder where you saved the fla.

4. copy the dae and material image to the folder .

5. compile it and enjoy

Here is the full code with the model.

Don't forget to add the papervision engine to it...

Baking of the texture helps to reduse the size of material. Well in Web scenario size matters .. :D

I think it's not complete one as am not sure about the 3D part. It's done by my genius designer. Well if you have any suggetions please

convey it to me . Am just trying to gather the information i got from different places.

Flash FLVPlayer in ActionScript 3.0

2010-02-18T19:13:00.000-08:00

Actionscript 3.0 , oh my god am scared of it . Whenever i know about actionscript 3.0 am confused with it.I have exposure only in AS 2.0 . I searched google for a year and could not get rid of this fear.
I read several books but none help me to understand the AS 2.0 . I have a good exposure in JAVA . But the thing is i can't differentiate OOPs with timeline based one.
Then i got this book.

Learning ActionScript 3.0 by Rich Shupe and Zevan Rosser

It's wonderful and awesome . When started reading this book my curiosity cross the limits and started to experiment with AS 3.0. As my main area is video , i experiment it with a flv player .
It may have problems and ubiquitous as it is my first experiment with AS 3.0. Anyway am sharing my source code and expecting some comments over it.

Requirements

1. Flash CS4

Dynamic XML/PHP driven rotating scroller using Tweenlite

2010-02-04T19:54:00.000-08:00

Oh My god , i had a blog here. I really forgot about this. :(

Now it's time to update my blog with a new thing . It's not so good one. Just tried to develop one simple scroller with rotating thumbs. You can change it to a XML/PHP driven scroller.
Till now am using Adobe default tween and Tweener class .
Then i found another famous one ,Tweenlite .It's fast and reliable for me. I never tried it. So decide to try it and develpoed a simple scroller.
You can have the source here .

Requirements

1. Flash CS4
http://www.adobe.com/products/flash/

2. TweenLite AS2.0
http://blog.greensock.com/tweenlite/

It's just another example . You can change to dynamic one by XML or PHP.

Network Manager in Fedora 9

2008-07-10T21:20:00.000-07:00

Nearly after one year I again tried to install GNU/Linux on my desktop. Last week I have installed Ubuntu-8.04 in my friend's machine and the desktop was really appealing. So, this time I decided to install the bleeding edge Fedora 9 in my machine.

I have managed some free space in the machine and installed Fedora without much hassles. The installation was very quick and it took almost 40 minutes to complete. Since I was not a casual GNU/Linux user, I ran into a couple of issues. First problem was with the Interrnet configuration. Later I discovered that the DNS address that I gave was wrong. The new Fedora theme and the package manager was wonderful. I added the livna rpm repository and installed my favourite VLC media player. Another great feature is the Malayalam support - after some minor tweakings from SMC, I was able to read and write Malayalam in OpenOffice.org and Mozilla Firefox. Things were smooth until I rebooted the machine next time.

When I reboot the machine, I was again struck with the network problems. This time the configuration was alright, but the NetworkManager has some fatal issues. It always shows Network not connected :(

I tried everything I know - reconfigured the network, rebooted the machine, modified the configuration files, but unable to connect to the network. I have no chance to search and find a solution as I have no connectivity and at last I have to logon to MS Windows ...

After some tedious search I got the solution(Sorry, I forgot to bookmark the link) and copied the page contents to a text file and again logged into the Fedora desktop. It says that desktops with a wired network, doesn't need the NetworkManager service. To increase the usability, in Fedora 9 the older network service is disabled by default.

To switch to using the old network service, I followed the following steps.

First disable the NetworkManager and prevent it from automatically loading:


[root@localhost ~]# /etc/init.d/NetworkManager stop
Stopping NetworkManager daemon: [ OK ]
[root@localhost ~]#  /sbin/chkconfig --level 35 NetworkManager off

You can also run the setup command and turn the NetworkManager off by pressing the bar.

Next, configure your network settings:

[root@localhost ~]# system-config-network

You should have an eth0 device already showing. To configure the IP settings click on Edit. Set the DNS address and then Save the settings.

Next, enable the service :

[root@localhost ~]# /etc/init.d/network start
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: [ OK ]

Make sure it loads at next boot:


[root@localhost ~]#  /sbin/chkconfig --level 35 network on

(You can also use the setup command)

Now I was able to connect to the Internet and post my first blog about Fedora. :)

Adobe goes OPEN SOURCE

2008-02-26T06:54:00.000-08:00

Yesterday(25/02/2008) I found an interesting thing.Adobe Started open source projects and also started a new site for the open source projects.I am expecting more from adobe .because i love to work with open source projects.The important thing in the adobe open source is ,they are converted the flex 3 sdk open source.And also they developing more application and ide for Linux platform also.

Now Flash media server,Flex 3 eclipse plugin ,Blazeds were available for the linux platform also.This is good sign for the developers in linux platform.Actually i am searching to work Flash in linux.I have tried with wine.But it need more system resource and it generate errors as well.Now i dreaming about to work Adobe applications in Linux platform.:D

This is a good news for the developers .Currentle adobe has been open the source of 9 projects.In this projects i think flex and blazeds were more important.The open source projects were;

1.BlazeDS
"BlazeDS is the server-based Java remoting and web messaging technology that enables developers to easily connect to back-end distributed data and push data in real-time to Adobe® Flex and Adobe AIR applications for more responsive rich Internet application (RIA) experiences." :adobe.
I have tried this with Flex and i am very happy to say that this is nice .I am thinking about my experience with the blazeds and flex.

2.Flex 3 SDK
"Adobe® Flex 3 is a cross platform, open source framework for creating rich Internet applications that run identically in all major browsers and operating systems.":adobe.

3.Flash Ajax Video Component

"The Flash Ajax Video (FAVideo) component is a small, open source Flash component that you can use to provide video playback within an Ajax application."

4.Generic Image Library

"Generic Image Library (GIL) is a C++ generic library which allows for writing generic imaging algorithms with performance comparable to hand-writing for a particular image type."

5.Adobe Media Gallery

"The Adobe Media Gallery (AMG) is a Flash web photo and video gallery whose appearance and behavior can be customized via XML files."

6.Adobe Source Libraries

"The Adobe Source Libraries (ASL) are a collection of C++ libraries building foundation technology to allow the construction of commercial applications by assembling generic algorithms through declarative descriptions. Updates monthly."

7.Tamarin

"The Tamarin project, which is based on code contributed from Adobe, is designed to implement the upcoming version of the ECMAScript 4th Edition language specification. "

8.Webkit

"The WebKit library is used to render HTML and execute JavaScript in Adobe® AIR. Adobe AIR allows web developers to deploy rich Internet applications on the desktop. "

9.XMP (eXstensible Metadata Platform)

"Adobe's Extensible Metadata Platform (XMP) is a labeling technology that allows you to embed data about a file, known as metadata, into the file itself."

And the thing is i have only tried the flex and blazeds.And the descriptions were form adobe site.

I think i have made bored you.So lets go here and find the things...:) .
have a nice day.

Flash FLV player using PHP

2008-01-23T07:28:00.000-08:00

After a long experiments , i have developed another player which uses XMOOV for streaming.Actually i got this php from flashcomguru.com.I didn't change the php file instead of it i developed a player using this php.
The player will start streaming anywhere from the file and it also make the seeking operation in the cached file.

Download Source here

I have no server space so i use freewebs space ,.Pls forgive me :D

The main problem of this technology is the performance of the php server.It need a good php server which can handle more requests at a time.
Other problem is the encoding of the flv. Flv file should be added with the 'keyframes' metadata . So it need another utility called metadata injector ,which will inject metadata to the flv. It can be downloaded from here.
That's all ..... and all other ups to you.
Try this..
If you are using this file please let me know your feedback.

Fullscreen in flash

2007-12-07T18:59:00.000-08:00

I am always confused with the fullscreen issue in flash in browser. At last,after many experiments i have developed a player which will support fullscreen. As this player may not be so good as many other Flash videoplayer ,consider as a experiment.
The player will receive the path to the flv as "path" param .

You can watch my experiment here.

I am happy to share my files with you.You can download from here
It containts:
1.The .fla file developed in "Flash CS3"
2.Player.as file
3.player.swf
4.flv folder which contain the flv file.

For testing purpose copy any flv of size 400 X 300 and rename as test and open the html in browser.

Please comment your opinions ,suggetions and doubts...

NOTE:The file developed in FLASH CS3
2.The Flv should be exactly of 400X300 size.
