C# :: .NET Zlib Stream Compatible With ByteArray.uncompress?

Oct 9, 2009

I can't seem to get a stream that Flex 3 want's to decompress.

I've tried:

System.IO.Compression.GZipStream
System.IO.Compression.DeflateStream
ICSharpCode.SharpZipLib.Zip.Compression.Streams.DeflaterOutputStream
zlib.ZOutputStream

None of these seem to make ByteArray.uncompress happy, i.e. I get

Error #2058: There was an error decompressing the data.

Also the whole Deflate vs zlib has me going around in circles. It seems that according to the wikipedia article, zlib is an implementation of DEFLATE. But according to Actionscript they are two different things?

Microsoft also seems to indicate the Gzip at least uses the Deflate algorithm, as in their docs they refer that GZipOutputStream uses the same compression algorithm as DeflateStream. So I'm assuming that it's just a header difference, which would indicate that's "no good" as far as 'ByteArray.uncompress' as the "DEFLATE" algorithm is only supported in AIR applications.

Sample "server" code, using SharpZipLib in this case (not working):

public virtual bool ProcessRequest(string path, HttpListenerContext context)
{
var buffer = File.ReadAllBytes(path);
// Specifying to strip header/footer from data as that seems to be what the

ActionScript 3.0 :: Uncompress Method Of ByteArray Only Supports Level 3 Compressed Streams?

Jun 4, 2008

Does the uncompress method of ByteArray only supports level 3 compressed streams? Because I have a valid zlib compressed file but compressed in level 2, and Flash always throws me the 2058 error message.

I've also tried using the DefaultCompressionAlgorithm class for AIR with its two compression methods, but with no success.

Doing some quick tests with python using the same file gets uncompressed with no problems.

Flash :: Where's A ByteArray's Data Stored

Oct 29, 2011

I'm using URLStream to download a big file and save locally on a mobile app. To do this, i need to store the downloaded bytes on a ByteArray:

private function handleStreamProgress(event : ProgressEvent) : void {
if ( urlStream.bytesAvailable == 0 ) return;
if ( urlStream.connected ) {

[Code]....

Are these bytes from the downloaded file stored in Memory? (Profiler doesn't show any excessive memory consumption, though...)

Should I clean the byteArray after each sequence of bytes is stored?

Flash - Play RAW Video Data From A ByteArray?

Nov 17, 2011

According to the NetStream API, Flash can play LOCAL RAW video by calling ns.play("raw:filename");.My question is how can Flash play RAW video data from a ByteArray? I have basically set my NetStream object to data generation mode by calling play(null), but whenever I call ns.appendBytes(byteArray) nothing is happening because apparently, appendBytes only support FLV data. how can I make Flash play raw video data from a ByteArray?

Flash :: Arrays - Passing Audio Data ByteArray To Javascript?

Sep 7, 2011

I'm able to record sound with a Flash application embedded in my website, this audio is saved to a ByteArray, which I need to pass to Javascript in order to post to my server along with other required data.

I know I can use AS3 ExternalInterface class to communicate with Flash from Javascript, but what would be the appropriate format or variable type in javascript to hold the ByteArray, and how can I ensure that I won't lose much audio data when doing so?

Python :: Uncompress Zlib String In Using ByteArrays

Dec 2, 2009

I have a web application developed in Adobe Flex 3 and Python 2.5 (deployed on Google App Engine). A RESTful web service has been created in Python and its results are currently in an XML format which is being read by Flex using the HttpService object.Now the main objective is to compress the XML so that there is as less a time between the HttpService send() method and result events. I looked up Python docs and managed to use zlib.compress() to compress the XML result.Then I set the HttpService result type from "xml" to "text" and tried using ByteArrays to uncompress the string back to XML. Here's where I failed. I am doing something like this:[code]Its throwing an exception at byteArray.uncompress() and says unable to uncompress the byteArray. Also when I trace the length of the byteArray it gets 0.[code]

ActionScript 3.0 :: Send Both Bytearray And Form Data?

May 11, 2010

I'm currently working on a small project. The user is supposed to draw/do a puzzle within flash, and also fill out a form with his details and comments.

When clicking the send-button, the image should be sent along with the form as an email.

I already know how to send the image as an email via php, and I know how to send a form as an email via php, BUT - I can't seem to do it together.

I've googled a bit and I found out that I cannot pass both the bytearray (from the image) and the form-data as URLVariables at the same time.

One way I got it to work is by passing the values from the form-data as a part of the URLRequest (and then use $_GET in the .php-file), but this has limitations as it can only pass 100 characters. As the user should be able to comment on his work, using GET with its limitations isn't an option.

Php :: Flex - Send A FLV Format Data In ByteArray Using URLloader To A Script?

Dec 15, 2010

Im creating flash game that have the functionality to capture/record its gameplay that can be viewed later by the user, like a replay.

As for now Im already able to record the game and write it into a flv format in a ByteArray variable.

What Im working right now is how to send that ByteArray(the video file) to a php script and save it to a web server.

I've run into the URLLoader in flash where it can send the data and php will receive it thru the POST method. Unfortunately, the ByteArray containing the flv data must be first correclty encoded for php to read it. I figured this out from the example in the net where it does the same thing only that it is only sending a JPEG ByteArray instead of a FLV format using the JPEGENCODER.

Is there any existing class like the JpegEncoder for FLV format or any Video formats? Or any work around like creating the encoder my self?

here is my current code to send the ByteArray

//send byteArray to a php script
var request:URLRequest = new URLRequest(url);
request.method = URLRequestMethod.POST;

Php :: Send More Than One 'stream' Of Jpeg ByteArray Data In A Single URLRequest And Output 2 Images?

Jan 25, 2011

I have an AS3 swf which users can upload jpg images to my EC2 instances which sit behind and Elastic Load Balancer. The jpg images are converted into bytearray data and sent using URLLoader.load(URLRequest)I make 2 calls when uploading, one to upload a large version, then another to upload a thumbnail version. A PHP script to which the bytearray data is uploaded converts this to a file using file_put_contents($destination,$GLOBALS["HTTP_RAW_POST_DATA"])Is it possible to combine these two requests into a single request which contains both the bytearray data for the large and thumbnail images and 'split' the HTTP_RAW_POST_DATA to create 2 files at the server. This would be better than uploading the bytearray for the large version then using something like ImageMagick to resize the resulting image into a thumbnail which I realise is another option.

Actionscript 3 :: Introduce A Sound From The Library To A ByteArray (and Then Play That ByteArray)?

Feb 16, 2011

I am working on a game, made with Flash (using AS3) The game has a fast ball and when this ball hits an object it has to make a sound... but the sound starts with delay (so the ball is far away when the sound is played).This sound is edited by me and it hasn't got any silences at the beginning.The method i'm currently using is the simplest one:

public var sonidoPuntos1:sonidopunto1 = new sonidopunto1()

and then...

sonidoPuntos1.play()

I am trying to introduce the file into a ByteArray and then playing it from there...

Php :: Flash - Sending ByteArray Through PHP?

Mar 22, 2011

The BLOB field (pic) is turning out as 0 Bytes when trying to send ByteArray through as3 to PHP, so i assume the PHP script or the HTTP_RAW_POST_DATA isn't working.I think the Flash part is working, I have set a trace() to see if the bitmapdata is coming through and it seems it is, so I'm assuming its my php side.3

private function export():void
{
var bmd:BitmapData = new BitmapData(600, 290);

Flash :: Converting A MovieClip To ByteArray?

May 25, 2011

I have to convert a MovieClip to ByteArray and send it to php using the POST method. The person handling php says that only ByteArray needs to be send and conversion to JPG and PNG can be done from PHP side. When I built the option for saving on the local machine the following steps were used.

Converting to Bitmapdata
Using JPGEncoder and PNGEncoder on the Bitmapdata
Then assiging to byte array variable.

So in this case different byte arrays were used for saving in case of JPG and PNG and it worked.

I found the code to convert movieclip to bytearray in Stackoverflow itself

Flash :: Finding String Into A ByteArray?

What is the simpliest way to find an occurance of some sequance of bytes (string) in a long byte array?

UPD: I tried to do

my_byte_array.toString().indexOf(needle_string);

the problem is that in flash/air string consist of utf8 characters, so indexOf will return value different from offset of "string" in a byte array (actually it's zip archive)
