    How to make video effects in PHP?

    in Third Party Scripts

    Posted

    Do you know of a way in php to do multitrack video editing? The only tool I have found online is a MltMelt, which is a command line utility. I'm in the process of making an app that merges multiple videos, photos and audio clips into one video, but I was wondering if there was a way to process this in php. Can anyone point me to a PHP library that can handle things like multitrack merging, transitions, color effects, blurring, etc?

     

    I'm looking for adobe premier like features in code.

     

    Stop imagecreatefromjpeg Error From Being Thrown

    in PHP Coding Help

    Posted

    I'm in the process of converting images from external websites references to images stored in my amazon S3 account.  I'm running a script to do the conversion for the images I need, however the script continues to break with this error message:

    E_WARNING: imagecreatefromjpeg(http://www.site.org/Ansichtskarten.images/I/AK04659a.jpg): failed to open stream: Connection timed out

    Is there anyway I can have the script just continue running even if there is an error? Restarting the script is frustrating and counterproductive.

    Script:

     

    <?php
ini_set('memory_limit','2048M');
ini_set('max_execution_time', 30000000);
ini_set("user_agent", 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.9) Gecko/20071025 Firefox/2.0.0.9');
ini_set('gd.jpeg_ignore_warning', 1);
$cron = true;
include('init.inc.php');

$query = 'SELECT * FROM city_images WHERE city_id > 0 ORDER BY city_id';
$city_images	= sql::q($query);
//var_dump($cities); die;

while ($row = sql::f_assoc($city_images)) {
	
	//var_dump($row);
	$city_id =  $row['city_id'];
	$image = image::resize_upload_amazon_new($row['image'], $row['city_id']);
	
	if(!is_array($image)){
		$sql = "INSERT INTO `city_images_new` (`city_id`, `image`)
				VALUES ('{$city_id}', '{$image}')";
			
		sql::q($sql);
	}
	//var_dump($image); die;
}
//die;
echo PHP_EOL . "Images converted succesfully"; die;

    Websockets Group Chat to Specific Users

    in PHP Coding Help

    Posted

    I have a running chat application in my website. It is implemented using websockets, php and is working fine. The problem is whenever i send a message to single user it broadcasts that message to all users currently connected to my website. It will be really helpful if someone can tell me how to get the unique id of each user when someone connects to our app. If i can get the userid of the current logged in chat user that would solve my problem but i am unable to retrieve that userid when the user connects (open state of websocket). I can get the userid when the connection is made but I need the userid before the connection happens. When the connecation occurs it assigns its own ids to the connected users in a serial manner(1,2,3..,n).

    <?php
// prevent the server from timing out
set_time_limit(0);

// include the web sockets server script (the server is started at the far bottom of this file)
require 'class.PHPWebSocket.php';

// when a client sends data to the server
function wsOnMessage($clientID, $message, $messageLength, $binary) {
global $Server;
$ip = long2ip( $Server->wsClients[$clientID][6] );

// check if message length is 0
if ($messageLength == 0) {
    $Server->wsClose($clientID);
    return;
}

//Send the message to everyone but the person who said it
foreach ( $Server->wsClients as $id => $client )
    if ( $id != $clientID )
        $Server->wsSend($id, "Visitor $clientID ($ip) said "$message"");
}

// when a client connects
function wsOnOpen($clientID)
{
global $Server;
$ip = long2ip( $Server->wsClients[$clientID][6] );

$Server->log( "$ip ($clientID) has connected." );

//Send a join notice to everyone but the person who joined
foreach ( $Server->wsClients as $id => $client )
    if ( $id != $clientID )
        $Server->wsSend($id, "Visitor $clientID ($ip) has joined the room.");
}

// when a client closes or lost connection
function wsOnClose($clientID, $status) {
global $Server;
$ip = long2ip( $Server->wsClients[$clientID][6] );

$Server->log( "$ip ($clientID) has disconnected." );

//Send a user left notice to everyone in the room
foreach ( $Server->wsClients as $id => $client )
    $Server->wsSend($id, "Visitor $clientID ($ip) has left the room.");
}

// start the server
$Server = new PHPWebSocket();
$Server->bind('message', 'wsOnMessage');
$Server->bind('open', 'wsOnOpen');
$Server->bind('close', 'wsOnClose');
// for other computers to connect, you will probably need to change this to your LAN IP or external IP,
// alternatively use: gethostbyaddr(gethostbyname($_SERVER['SERVER_NAME']))
$Server->wsStartServer('127.0.0.1', 9300);

    Potential Output Buffering Issue

    in PHP Coding Help

    Posted

    I think I have an output buffering issue, but I don't understand it because in my php.ini file I have outbuffering = On .

     

    [05/08/2013 11:16:01] E_WARNING: Cannot modify header information - headers already sent by (output started at /admin.local.com/show.php:1) in /admin.local.com/assets/init.inc.php on line 178

     

    In my init.inc.php file I have:

    <?php
ob_start();
session_start();

date_default_timezone_set("America/New_York");
setlocale(LC_MONETARY, 'en_US.UTF-8');

    MAMP is giving me the following error:

    Do you know why this would happen?

    This is line 8 in init.inc.php:

    What is the best method for resizing images to a fixed height and width while maintaining image ratio?

    in PHP Coding Help

    Posted

    On my startups site you'll notice in the featured destinations section that I have destination images that have a fixed height and width set by using CSS. The problem is that my images do not maintain their proportion, yet I want them at this size and I want them to look good.

    How should I resolve this issue? Should I make sure that all images that are uploaded are cropped at the necessary ratio? If so, can I do this automatically using PHP so that I don't have to manually do it?

     

    PHP Exec Function Doesn't work with cd Ubuntu Command

    When I run

     

    $dir = shell_exec('cd /var/www/trekeffect.com/trekeffect.com;pwd');

$this->log($dir);

    I've already done that using the below code, but it doesn't work:

     

    $this->log('Enter Execute');

    Hey guys... I change my script around and for some reason it doesn't seem to be working any more. Do you know why?
     

    $this->log(getcwd());
          
//chdir('/mysite.com/mysite.com');
shell_exec('cd /var/www/mysite.com/mysite.com', $output);
         
$this->log(getcwd());

    The out put for that is:

    2013-04-12 12:21:57-04:00 --- INFO: /var/www/deploy
    2013-04-12 12:21:57-04:00 --- INFO: /var/www/deploy

     

    I don't receive an noticeable errors.  I also tried the chdir function but that kills my script and the second log won't occur.  Any ideas?

    Automate Deployments with Git, Bitbucket and PHP

    in PHP Coding Help

    Posted

    I'm in the process of trying to set up automatic deployments when I make a git push to my bitbucket repository. I have a php deploy script that I leveraged from http://brandonsummers.name/blog/2012/02/10/using-bitbucket-for-automated-deployments/ but when the script runs it is logging that it's only updating from a previous commit.

    Here is an example. Let say I log into my server and type git pull. The server will update with the latest changes and lets say the hash for that commit was 001. However if I make serveral commits lets call them 002, 003, and 004 my script should run every time assuming I pushed those changes to bitbucket after every commit. The script runs but every time it will keep the changes from 001. Only when I log into my server and type git pull, will the server update to 004. Do you know what would cause this?

    Edit Backbone Ajax Success Method to Add in Custom Error Handling

    in Javascript Help

    Posted

    I have my own custom error code inside of a backbone ajax success method in case the server returns an error. The problem is that this code is repeated throughout my app and I wanted to edit the success function in one place so I don't have to constantly repeat this error handler in every ajax success. I want to edit the success function to include this error check wrapper. Do you know how to do that?

    Here is an example of my success method in one of my views:

     

    "success" : function success(model, data)
			    {
				 if(data['error'] !== undefined && data['error'].length === 0)
				  {
				   message('error', 'Whoops! System Error. Please refresh your page.');
				  }
			    else if(data['error'] !== undefined)
				 {
		          message('error', data['error']);
				 }
			    else
				 {
				  //add templates and do stuff here
				 }
			   }

     

    Ideally I'd like to set that in a config somewhere and then I'd just be able to use:

     

    "success" : function success(model, data)
	            {
				 // add templates and do stuff here
			    }

     

    Is this possible? I tried using ajaxSetup but that didn't seem to work for me.
