Play flv byte array in Air Application
I'm trying to load and play an FLV from a ByteArray in Air application . I have created small dummy application in which l am readiong flv from file system .After reading flv file i have byte array so can you please help me out in thi how to p-lay flv from byte array.
I have searched the web for awnsers and didn't find anything .
Any help, ideas or something?
Hi Giuseppe,
what I do is:
1. create a file using Captivate
2. i place a .flv video in this file
3. save the file as .swf
4. then i go to dreamweaver and put the swf on a html page.
Now:
when viewed in a browser, everything runs fine.
when i pack this page into an air application (in dreamweaver) the video does not appear,
instead I get this "Connection Error"
I do not know a console or log file.
However, I learned that there is a .xml file located in the same AIR folder that you publish in.
In this .xml file there is a setting :transparency. in order to playt a .flv file this must not be be "transparent"!
(i read this somewhere in the net)
hope that helps
I will talk to a professional programmer, if I have any news, i will let you know

How to embed and play mp4 video in HTML AIR application?
Adobe Air HTML / JS application compiled from SDK command line. I am not using flash pro or flash builder to create the application.
I was using dreamweaver but the dw air plugin seems to have stopped being developed so I switched to using the command line tools.
I am creating desktop air application that has embedded mp3 audio and also I want to embed mp4 video.
Using jQuery and the AIR js plugin I am able to play audio via buttons hooked up via jQuery and the AIR js plugin from the SDK.
What I am doing is creating proofs for clients in AIR and sending link to the client to download the application. I embed the media because I do not want to place them on a website where it could possibly be seen by non-clients and get picked up in the SE's.
I am finding it hard to understand the AIR process for playing video. I read that it is the same procedure as audio but it does not work.
If it was hosted on youtube or somewhere embedding the web player would be simple, just copy paste some code and it works. When actually embedding the video say mp4, f4v, mov, wmv or similar file formats I can't get AIR to play the video. Audio, not a problem it works great.
I would like to do the following with video.
Embed the actual file in the AIR app. I can do this, it gets embedded.
Play, pause and stop the video - Can't get this to work
Get the current stop point and be able to start the video by sending a start point - This is all working with audio I just want to do it with video.
I have searched the forums, the search engines, youtube and read through the documentation on Air but the video does not work at all.
I need code samples and direction on how to make an embedded video play inside of a desktop air application using the HTML / JS air model. I am using the command line tools to create the air package and test the air app.
Please help if you have figured this out.
Thank you.
Not sure if this matters but I am using Windows 7 Pro 64bit as my development machine.In addition I also can not get html5 video to play in the adobe air app. Would this issue be tied to the above?

How to Play/Pause All for Adobe Air Application using AS3 in Flash CS4?
I am new to Flash and I'm creating an educational application in AS3 in Flash CS4 for Adobe Air. I want to use buttons to play and pause all content (movieclips AND sound).
I have created play and pause buttons that worked by switching the frame rate between 0 and 20, unfortunately I've realised that it's never really 0fps but rather 0.01fps and so it continues playing, albeit very very slowly. Also this doesn't affect the audio; I have set sound files to Stream which are synced to movieclips on their timelines, but even when the application is set to 0fps the audio continues.
Since I have various levels with numerous movieclips each with synced audio, what i'd like is to be able to do is pause absolutely everything within each movieclip with one button and to be able to resume from the same place using another button. Is this possible? If not, is there a global function to pause/resume the entire application/program?
Thanks in advance for your help!Its possible but you would need to tell each movieclip and audioclip to play/pause. You can create a for loop inside your mouse event function to find each movieclip and pause/play its timeline and a separate for loop for audio clips. Also instead of setting fame rate to 0 for pause just use a stop() command.

Flv video not playing in AIR application
Hi everybody,
i'm building a tutorial with flash catalyst and since the 20 states limit i've split it up in different swf files that I import and show in different states.
One of these swf (which i built with Catalyst as well) is supposed to play a flv video, and it actually plays it if i run it alone.
The problem comes when i build the overall tutorial: it works perfectly with the "run project" command in Catalyst and with the run-local version but the video won't play if i try the AIR application.
Does anyone have any suggestion?
NB: the "asset" directory created with the AIR application installer does contain the flv file (i didn't have to put it there manually)
Thanks in advance for your help,

1. create a file using Captivate

How to play and stop flv files through NetStream in AIR Application
Hi,
In a folder I have 'n' number of flv file, which are DRM protected. when the user try to play those files for the first time through my AIR application, it will prompt for username and password and gets the license/voucher from the server and store it in AIR Runtime. so that from the next time onwords it won't prompt for username and password as because it already has license/voucher.
My problem is assume there are 500 files, such that for each file the user has to enter his credentials[username and password]. which is a stupid thing. I want to avoid this process by implementing this process internally/programetically. By playing/accessing each file through netstream from the folder and setDRMAuthenticationCredentials for that file and stop the stream. Here I am able to play each file but I am failed to stop it. I mean to say I will get the license for all the flv files internally[while loading my AIR application], such that user should not be interrupted for his credentials for each file.He should play as if he is accessing/playing a non-DRM protected file. I will be very thank full if any one help me out in this.
public function init():void {
connectStream();
getLicenseForAllFiles();

FLV Playback and Seekbar on different native windows in one Air application
Hello Everyone. I'm trying to make a simple video playback AIR application that utilizes the initial native window to house a transport control with a seekbar on it. Once the application launches, it creates a second (new) window on my second screen and places a FLVPlayback instance on that new window. Everything works just like it want it to except for one thing. When the seekbar and FLVplayback instance are not located on the same window stage, the seekbar handle sticks to the mouse when trying to scrub through the video.
I've added both the transport control and the FLVPlayback instance to the original native window as children and I have also added both of them to the new window as children and everything works just fine. It's only when they are separated and located on different stages that the seekbar acts up. When they are on the same stage, I can click on a point on the seekbar and the video jumps to that spot and continues to play and I can also scrub the seekbar, the video updates as I scrub, and when I release the mouse, the seekbar handle stays where I released the mouse. When they on separate stages, the seekbar handle continues to follow the mouse movement without releasing it. The video updates as the seekbar handle is moved due to it sticking to the mouse, but if I release the mouse, the handle is still moving with the mouse and the video is still being scrubbed. Like I said, everything works great except for this and I have reached my limit with time spent on this issue. Does anyone have any insight into this?
Here's my code for the project. This is my first AIR application, so I am coding it as I am learning, please be kind.

Android Video play via AIR application is jerky
Hi All,
We are developing an AIR mobile application targetted for Android 2.2 or above. One of the requirement is to play H.264 videos on the mobile from the Assets folder (local file system). We have run in to a show stopper while trying to implement this feature, here are the details -
1. We are using OSMF that comes bundled with Flex Builder 4.6
2. Using Adobe AIR 3.1 and Flex SDK 4.6
When video of quality H.264 MPEG4 1280*720 30FPS with input bit rate 2000 is being played on the mobile device (android), the video frame rate is choppy however on the desktop it plays out fine... StageVideo is something I would like to try however, at this moment I have no access to Android 3.0 which is required for StageVideo...
What are we missing? Is AIR 3 not capable to play H.264 videos on android, though the Android native video player plays it out just fine?
Regards
BaligaHi,
Video encoding is very important.
For example, use baseline profile level 3.1 for H264 for mobile
(and not High profile level 4.1 recommended for desktop).
For more information, see the MAX session of Fabio Sonnati:
"Encoding for Performance on Multiple Devices"
And if you have an Android phone/tablet, there is my AIR application
to watch Adobe MAX 2011 videos :
https://market.android.com/details?id=air.fr.inway.maxVideos2011
Search "Sonnati" for this session's video.
(For info, i use a video player based on OSMF 1.6)
The pdf presentation is available on Sonmati's blog:

User to User file transfer via FMS or RED5 in AIR application.
Hello!
It is possible to make file transfer from air application via server?
I think need to create like byte array streaming or somethink like this from sender and write the destination file on receiver user pc.
Someone know how to do this? It is possible?
Thanks.Search more on socket class you can send anything between two machines using them
see the code snippet below:
sc = new Socket("<IP address>",8000);
sc.connect("<IP address>",8000);
sc.addEventListener(ProgressEvent.SOCKET_DATA, readFromServer);
sc.writeUTFBytes("Hi this will be sent to the IP address provided by you on port no 8000!\n");
sc.flush(); -
Convert XML data to byte array...
Hello All,
In my application, i have an XML file and the corresponding XSD file. This XML file is having some date, which i want to convert into an byte[] and then save it in a file.
How i can convert the XML data in the byte[]? Here as an example of the xml file and the byte[] data which i want to save in a file.
<?xml version="1.0" encoding="utf-8"?>
<HeadersInfo>
<header>
<id>0</id>
<Name>H1</Name>
</header>
<header>
<id>1</id>
<Name>H2</Name>
</header>
</HeasersInfo>
In the above example 'id' field is of type 'uint' and 'name' field is of type 'string' with max length of '5'. So in this case my byte array should be as shown below:
00 00 00 01 48 31 00 00 00
00 00 00 02 48 32 00 00 00
Here underlines values are for the 'id' parameter where as values in bold are for 'Name' parameter for all the header values in sequence. Name parameter is null (0x00) padded.
Thanks in advance,
IamHuMHi,
the following example extract the id, name values using LINQ To Xml and writes it to a memory stream using a binary writer and returns the result as a byte array:
internal static byte[] GetXmlAsByteArray()
var document = XDocument.Parse("<HeadersInfo>"
+ " <header><id>1</id><Name>H1</Name></header>"
+ " <header><id>2</id><Name>H2</Name></header>"
// additional testing
+ " <header><id>32767</id><Name>H1234</Name></header>"
+ " <header><id>305419896</id><Name>H56789</Name></header>"
+ "</HeadersInfo>");
const int NameLength = 5; // Max length for a name
byte[] zeroBytes = new byte[NameLength]; // Helper to fill name
using (var ms = new MemoryStream())
using (var writer = new BinaryWriter(ms))
// write each header
foreach (var header in document.Root.Elements("header"))
int id = (int)header.Element("id");
string name = (string)header.Element("Name");
byte[] nameBytes = System.Text.Encoding.UTF8.GetBytes(name);
Console.WriteLine("id: {0}, Name: {1}", id, name);
// Write id
writer.Write(GetUIntBytes((uint)id));
// Write name NameLength (5) max, otherwise padded
if (nameBytes.Length > NameLength)
writer.Write(nameBytes, 0, NameLength);
else
writer.Write(nameBytes, 0, nameBytes.Length);
if (nameBytes.Length < NameLength)
writer.Write(zeroBytes, 0, NameLength - nameBytes.Length);
byte[] result = ms.ToArray();
// dump array
foreach (var value in result)
Console.Write("{0:X2} ", value);
Console.WriteLine();
return result;
public static byte[] GetUIntBytes(uint value)
if (BitConverter.IsLittleEndian)
// swap bytes
value = ((value & 0x00ff) << 24)
| ((value & 0xff00) << 8)
| ((value & 0x00ff0000) >> 8)
| ((value & 0xff000000) >> 24);
return BitConverter.GetBytes(value);
For a general purpose solution you should create a class and split the example into separate methods to extract the data and write the values (integers, strings).

How to get a string or byte array representation of an Image/BufferedImage?
I have a java.awt.Image object that I want to transfer to a server application (.NET) through a http post request.
To do that I would like to encode the Image to jpeg format and convert it to a string or byte array to be able to send it in a way that the receiver application (.NET) could handle. So, I've tried to do like this.
private void send(Image image) {
int width = image.getWidth(null);
int height = image.getHeight(null);
try {
BufferedImage buffImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
ImageIcon imageIcon = new ImageIcon(image);
ImageObserver observer = imageIcon.getImageObserver();
buffImage.getGraphics().setColor(new Color(255, 255, 255));
buffImage.getGraphics().fillRect(0, 0, width, height);
buffImage.getGraphics().drawImage(imageIcon.getImage(), 0, 0, observer);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
JPEGImageEncoder jpeg = JPEGCodec.createJPEGEncoder(stream);
jpeg.encode(buffImage);
URL url = new URL(/* my url... */);
URLConnection connection = url.openConnection();
String boundary = "--------" + Long.toHexString(System.currentTimeMillis());
connection.setRequestProperty("method", "POST");
connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);
String output = "--" + boundary + "\r\n"
+ "Content-Disposition: form-data; name=\"myImage\"; filename=\"myFilename.jpg\"\r\n"
+ "Content-Type: image/jpeg\r\n"
+ "Content-Transfer-Encoding: base64\r\n\r\n"
+ new String(stream.toByteArray())
+ "\r\n--" + boundary + "--\r\n";
connection.setDoOutput(true);
connection.getOutputStream().write(output.getBytes());
connection.connect();
} catch {
}This code works, but the image I get when I save it from the receiver application is distorted. The width and height is correct, but the content and colors are really weird. I tried to set different image types (first line inside the try-block), and this gave me different distorsions, but no image type gave me the correct image.
Maybe I should say that I can display the original Image object on screen correctly.
I also realized that the Image object is an instance of BufferedImage, so I thought I could skip the first six lines inside the try-block, but that doesn't help. This way I don't have to set the image type in the constructor, but the result still is color distorted.
Any ideas on how to get from an Image/BufferedImage to a string or byte array representation of the image in jpeg format?Here you go:
private static void send(BufferedImage image) throws Exception
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
ImageIO.write(image, "jpeg", byteArrayOutputStream);
byte[] imageByteArray = byteArrayOutputStream.toByteArray();
URL url = new URL("http://<host>:<port>");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setRequestMethod("POST");
OutputStream outputStream = connection.getOutputStream();
outputStream.write(imageByteArray, 0, imageByteArray.length);
outputStream.close();
connection.connect();
// alternative to connect is to get & close the input stream
// connection.getInputStream().close();

Trying to send multiple types in a byte array -- questions?
Hi,
I have a question which I would really appreciate any help on.
I am trying to send a byte array, that contains multiple types using a UDP app. and then receive it on the other end.
So far I have been able to do this using the following code. Please note that I create a new String, Float or Double object to be able to correctly send and receive. Here is the code:
//this is on the client side...
String mymessage ="Here is your stuff from your client" ;
int nbr = 22; Double nbr2 = new Double(1232.11223);
Float nbr3 = new Float(8098098.809808);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(baos);
oos.writeObject(mymessage);
oos.writeInt(nbr);
oos.writeObject(nbr2);
oos.writeObject(nbr3);
oos.close();
byte[] buffer = baos.toByteArray();
socket.send(packet);
//this is on the server side...
byte [] buffer = new byte [5000];
String mymessage = null; int nbr = 0; Double nbr2 = null;
Float nbr3 = null;
mymessage = (String)ois.readObject();
nbr = ois.readInt();
nbr2 = (Double) ois.readObject();
nbr3 = (Float) ois.readObject();
My main question here is that I have to create a new Float and Double object to be able to send and receive this byte array correctly. However, I would like to be able to have to only create 1object, stuff it with the String, int, Float and Double, send it and then correctly receive it on the other end.
So I tried creating another class, and then creating an obj of this class and stuffing it with the 4 types:
public class O_struct{
//the indiv. objects to be sent...
public String mymessage; public int nbr; public Double nbr2;
public Float nbr3;
//construct...
public O_struct(String mymessage_c, int nbr_c, double nbr2_c, float nbr3_c){
my_message = my_message_c;
nbr = nbr_c;
nbr2 = new Double(nbr2_c);
nbr3 = new Float(nbr3_c);
Then in main, using this new class:
in main():
O_struct some_obj_client = new O_struct("Here is your stuff from your client", 22, 1232.1234, 890980980.798);
oos.writeObject(some_obj_client);
oos.close();
send code....according to UDP
However on the receiving side, I am not sure how to be able to correctly retrieve the 4 types. Before I was explicitely creating those objects for sending, then I was casting them again on the receiving side to retrieve then and it does work.
But if I create a O_struct object and cast it as I did before with the indiv objects on the receiving end, I can't get the correct retrievals.
My code, on the server side:
O_struct some_obj_server = new O_struct(null, null, null. null);
some_obj_server = (O_struct)ois.readObject();
My main goal is to be able to send 4 types in a byte array, but the way I have written this code, I have to create a Float and Double obj to be able to send and receive correctly. I would rather not have to directly create these objects, but instead be able to stuff all 4 types into a byte array and then send it and correctly be able to retrieve all the info on the receiver's side.
I might be making this more complicated than needed, but this was the only way I could figure out how to do this and any help will be greatly appreciated.
If there an easier way to do I certainly will appreciate that advise as well.
Thanks.public class O_struct implements Serializable {
// writing
ObjectOutputStream oos = ...;
O_struct struct = ...;
oos.writeObject(struct);
// reading
ObjectInputStream ois = ...;
O_struct struct = (O_struct)ois.readObject();
I will be sending 1000s of these byte arrays, and I'm sure having to create a new Double or Float on both ends will hinder this.
I am worried that having to create new objs every time it is sending a byte array will affect my application.
That's the wrong way to approach this. You're talking about adding complexity to your code and fuglifying it because you think it might improve performance. But you don't know if it will, or by how much, or even if it needs to be improved.
Personally, I'd guess that the I/O will have a much bigger affect on performance than object creation (which, contrary to popular belief, is generally quite fast now: http://www-128.ibm.com/developerworks/java/library/j-jtp01274.html)
If you think object creation is going to be a problem, then before you go and cock up your real code to work around it, create some tests that measure how fast it is one way vs. the other. Then only use the cock-up if the normal, easier to write and maintain way is too slow AND the cock-up is significantly faster. -
How to create a jar having the contents of the jar in a byte array?
Hi,
I have a server and client application. My server returns the contents of the jar in the form of byte array to the client on a particluar method call. Now at the client end, i want to reconstruct the jar to be used. How do I do this?
The server uses the JarInputStream to read the contents of the jar to be returned. I have tried using the JarOutputStream, but looks like this works fine if we have spearate class files to be added to the jar. Now that I have the contents of the jar itself, how do i recreate the jar?
Can anyone please help me with this?
Thanks
RajaniHave you ever gotten the raw byte copy to work? If so, how?
I download a jar via InputStream and save into a jar file via fileoutputstream. It always gets corrupted in the process. The new Jar file has the exact same number of bytes, but doesn't get past the Manifest on a -tvf. In fact, Winzip can open it fine, but can't extract. So close...yet so far.
Here is a snapshot of my code:
BufferedInputStream data1=new BufferedInputStream(con.getInputStream());
DataInputStream data=new DataInputStream(data1);
StringBuffer buf=new StringBuffer();
try{
while((theChar=data.read()) != -1)
{ buf.append((char)theChar); }
} catch (Exception z){ logger.info("UpdateThread.read Done Reading jar file");}
data.close();
File newFile = new File("C:/MyJar.jar");
FileOutputStream outstream2 = new FileOutputStream(newFile);
DataOutputStream outstream1 = new DataOutputStream(outstream2);
BufferedOutputStream outstream = new BufferedOutputStream(outstream1);
byte [] bytes = buf.toString().getBytes();
logger.info("Bytes of new Jar file = " + bytes.length);
int i;
for(i=0;i<bytes.length;i++){
outstream.write(bytes);
outstream1.close();
outstream.close();
Any ideas where I'm going wrong?
