equal function String.fromCharCode in PHP

Hey it was problem before I see this solution, to pass charactes to PHP like numbers, basicly because Flash use fromCharCode in UTF-8 format and PHP do chr function work in ASCII.

So here is the script solution:

function uniord($ch) {

    if ($n < 128) {
        return $n; // no conversion required
    }

    if ($n < 192 || $n > 253) {
        return false; // bad first byte || out of range
    }

    $arr = array(1 => 192, // byte position => range from
                 2 => 224,
                 3 => 240,
                 4 => 248,
                 5 => 252,
                 );

    foreach ($arr as $key => $val) {
        if ($n >= $val) { // add byte to the 'char' array
            $char[] = ord($ch{$key}) - 128;
            $range  = $val;
        } else {
            break; // save some e-trees
        }
    }

    $retval = ($n - $range) * pow(64, sizeof($char));

    foreach ($char as $key => $val) {
        $pow = sizeof($char) - ($key + 1); // invert key
        $retval += $val * pow(64, $pow);   // dark magic
    }

Camera.getCamera problem => solution

Posted in actionscript 3, example on January 23rd, 2010 by admin – Comments Off

When you try to add a camera by name like this:

1
2
var cameraName:String = "WebCam";
var cam:Camera = Camera.getCamera(cameraName);

or like this

1
var cam:Camera = Camera.getCamera(cameranames[0]);

both return cam = null

Solution:

You need to add camera index like String in order to work

1
2
3
4
5
6
7
8
9
10
11
var cameraName:String = "WebCam";
var camera:Camera;
const imax:int = Camera.names.length;
var i:int = 0;
while (i < imax) {
    if (Camera.names[i] == cameraName) {
        camera = Camera.getCamera(String(i));
        break;
    }
    i++;
}

or use this function

12
13
const camera:Camera = getCamera("webCam");
       
private static function getCamera($cameraName_:String):Camera {
    const imax:int = Camera.names.length;
    var i:int = 0;
    while (i < imax) {
        if (Camera.names[i] == $camName_) {
            return Camera.getCamera(String(i));
        }
        i++;
    }
    return null;
}

so now you will have your camera that you wanted:

Flash video Player Snapshot

Posted in PHP, actionscript 3, projects & snippets on September 14th, 2009 by admin – Comments Off

Hi I have recently working on saving different format images from flash. My previous work on this script was: Image Encode with Flash and PHP. Here you can create snapshots from video source.

Example

In this example you can save exported images also in your computer. I like this example more, because you can get different images, not boring same image again.

Screenshots:
snapshot file 1
snapshot file 2
snapshot file 3

Custom Flash Video Player

Posted in actionscript 3, projects & snippets on September 14th, 2009 by admin – Comments Off

I created easy to functionality to extend player. Here is the link:
video player

You pass total of 4 flash variables:

1
2
3
4
5
var flashvars = {};
flashvars.videoURL = "running man.mp4";
flashvars.autoPlay = 0;
flashvars.isImage = 1;
flashvars.imageURL = "RunningMan.jpg";

I’m using swfobject ot embed it in page. So lets say little more about variables:
videoURL is link to video location;
autoPlay is flag, if = 1, then video will start automatically playing. If = 0, then will stay stopped until play button is clicked;
isImage is flag, if = 1, them you have to pass image location to imageURL variable, to be loaded.If = 0, then no image is loaded;
isImage is image location;

Note: autoPlay and isImage cannot be 1 at the same time! Player will throw error. Also please use 0 or 1 for flags, not false or true.

Image Encode with Flash and PHP

Posted in PHP, actionscript 3 on September 10th, 2009 by admin – Comments Off

hi, this is a little project to save export/save images from flash.

This application allow you to see how to export in different image formats like: png, jpg and bmp.

I create class ImageCreator, whit it it’s this easy create images on server. You call the class like this:

1
2
var imagecreator:ImageCreator = new ImageCreator(image_spr, ImageCreator.EXPORT_TYPE_PNG, name);
imagecreator.addEventListener(ImageCreator.EVENT_COMPLETE_SAVING, completeWritingEvent);

Event ImageCreator.EVENT_COMPLETE_SAVING, will be dispatched when image is correctly saved on your server.
This is ImageCreator Class
