I would like to use FileReference.save() in 4 different place in a flash game. All 4 methods are the same (copy & paste). Locally, all 4 work perfectly however when I put the swf in browser, facebook actually, only one of them works as expected and the others do not. In Chrome, all 3 have never worked. In Safari, they work sometimes but nondeterministic. What can be the reason? Any idea?
By the way, I compiled with Air 2.5 and Air 3.2 Desktop, I use Flash CS6
private function onScreenShotButtonClicked(e:MouseEvent)
{
mScreenShotButton.removeEventListener(MouseEvent.CLICK, onScreenShotButtonClicked);
var finalBitmapData:BitmapData = new BitmapData(810, 520, true, 0x00000000);
var finalBitmap:Bitmap = new Bitmap(finalBitmapData, PixelSnapping.ALWAYS, false);
finalBitmapData.draw(mParent.root);
var finalData:ByteArray = new ByteArray();
finalData = PNGSave.encode(finalBitmapData);
var tempFileReference:FileReference = new FileReference();
tempFileReference.addEventListener(Event.COMPLETE, onSaveCompleted);
tempFileReference.addEventListener(Event.CANCEL, onSaveCancelled);
tempFileReference.save(finalData, "boombox.png");
}
The common problem is that your method dont't have MouseEvent instance param. May be you call Filereference.save () but you don't have a event argument in function.

I have a slightly unusual situation with SharedObject:
The situation: where we have a SWF (browser) based application running on a single local machine. The SWF accesses local content and is reloaded every XX number of seconds/minutes/hours.
The state of application has to be stored within a single SharedObject (this is using the '/' parameter to force it to global) in a JSON style.
The SWF loads the SO before it makes any state updates and correctly calls flush() immediately after to save state.
The Problem: Everything runs fine BUT occasionally there is a situation where by 2 instances of the same SWF are existing at the same in different instances and both are accessing the same SharedObject.
The 2nd has to take control of the SO from the 1st, by each SWF instance setting it's instance state to an incremented number (SWF Idx) stored in the SO.
Both are loading the file before any update is made, version number checked, and will disable themselves if the saved SWF Idx is above it's own. Unfortunately the 1st SWF instance somehow isn't loading the latest version of the SharedObject because it traces out the original number (e.g. 22) instead of the now updated one (e.g. 23). While the 2nd SWF is tracing out 23 and the SO contains 23.
Is there any way that the browser could possibly be caching the SO?
Testing
I'm currently testing the situation by running one browser instance locally then launching a 2nd. Making copies of the SO before and after each state.
I've also run the 1st and 2nd via IntelliJ and can see that SharedObject.getLocal is being called and checked each time.
I've included the basics of the code I'm using below where:
__so = is the public SharedObject variable
_thisSWFIdx = is the private variable inside AS3 storing the current instances SWF Index
__so.data.activeSWFIdx = the latest SWF Index
The SO 'get' I'm using is:
SharedObject.getLocal(_SO_ID, "/");
The check i'm doing is:
if (_thisSWFIdx < __so.data.activeSWFIdx) {
__amActiveSWF = false;
}
The saving of the variable to SO:
__so.data.activeSWFIdx = _thisSWFIdx;
flush();
Additonal info:
This is running on both mac & windows
FlashPlayer 10.3
Pure AS3
compiled in IntelliJ
same issue in FF, Chrome and IE
primary machine Macbook
I can't find anything within the documentation or existing threads so any help will be much appreciated.
After a little test, I remarked the behavior that you've mentioned : after updating the SharedObject by a second SWF, the first one can't get the new value only after a reload.
To avoid that, I think, as a workaround, you can use a second SWF which will just work on the SharedObject by reading / writing data.
For that, take this example :
so.swf : the SWF which will read and write data.
var shared_object_name:String = 'so';
var shared_object:SharedObject = SharedObject.getLocal(shared_object_name, '/');
// get the id
function get_id(): int {
return shared_object.data.id ? shared_object.data.id : -1;
}
// set the id
function set_id(new_id:int): void {
shared_object.data.id = new_id;
shared_object.flush();
}
app.swf : your global app which will use the "so.swf" to do SharedObject's operations :
var init:Boolean = true;
var swf_id:int = 1;
var swf_disabled:Boolean = false;
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, on_SWFLoad);
loader.load(new URLRequest('so.swf'));
function on_SWFLoad(e:Event): void
{
var loaded_swf:MovieClip = MovieClip(loader.content);
var current_id:int = loaded_swf.get_id();
// if it's initial run
if(init){
init = false;
if(current_id > 0){
swf_id = current_id + 1;
}
loaded_swf.set_id(swf_id);
} else { // we are verifying if there is a new active SWF
if (swf_id <= current_id) {
swf_disabled = true;
}
}
}
function stage_onPress(e:MouseEvent){
// if this SWF is disabled, stop getting the "id"
if(swf_disabled){
stage.removeEventListener(MouseEvent.CLICK, stage_onPress);
return;
}
// otherwise, get the "id" to verify if there is another active SWF
loader.load(new URLRequest('so.swf'));
}
stage.addEventListener(MouseEvent.CLICK, stage_onPress);
I used MouseEvent.CLICK only for testing purposes, of course you have to use a Timer or something else to verify every n seconds (for example) that you have another active SWF to disable the current one...
Hope that can help.
I am wondering if someone who has handled NetStream.appendBytes in Flash knows how to get the bitmapData from a decoded video frame? I have already looked at this question but that is from 3 years ago and the more recent comment/answer seems to be gone. In 2014 has anyone managed to turn those bytes into a bitmap? I am working with Flash Player 11.8 and this is not a desktop/AIR app.
In the image below I can do steps 1) and 2) but there's a brick wall at step 3)
The problem is that simply using bitmapdata.draw(video_container); does not work but instead it throws a Policy File error even though I am using a byteArray (from local video file in the same directory as the SWF). No internet is even involved but Flash tells me that "No Policy File granted permission from the server" or such nonsense. I think the error is just a bail-out insteading of straight up saying "You are not allowed to do this.."
I have tried: trying to appease this Crossdomain.xml issue anyway and looking into all known security/domain settings. I came to the conclusion that the error is not the problem but a side effect of the issue.. The issue here being that: Flash Player is aware of the SWF's location and of any files local to it. That's okay when you pass a String as URL etc but when the Netstream data is not local to the SWF domain then it becomes a Policy File issue. Problem is my data is in the Memory not in a folder like the SWF and therefore cannot alllow bitmapData.draw since it cannot "police" an array of bytes, any known fixes for this?... (I can't even say the words I really wanted to use).
What I am trying to achieve: Is to essentially use Netstream as an H.263 or H.264 image decoder in the same way Loader is a JPEG-to-Bitmap decoder or LoadCompressed.. is an MP3-to-PCM decoder. You know, access the raw material (here RGB pixels), apply some effects functions and then send to screen or save to disk.
I know it is a little late, but I think I found a solution for your problem.
So, to avoid the Security sandbox violation #2123 Error, you have just to do like this :
// ...
net_stream.play(null);
net_stream.play('');
// ...
Hope that can help.
I know this question is a couple months old, but I wanted to post the correct answer (because I just had this problem as well and other will too).
Correct answer:
It's a bug that has been open at adobe for almost 2 years
Link to the bug on Adobe
Work Around until the bug gets fixed (I am using this and it works great):
Workaround using Sprite and graphics
To take a snapshot from a video stream we don't need NetStream.appendBytes which inject data into a NetStream object.
For that we can use BitmapData.draw which has some security constraints. That's why in many times we get a flash security error. About that, Adobe said :
"... This method is supported over RTMP in Flash Player 9.0.115.0 and later and in Adobe AIR. You can control access to streams on Flash Media Server in a server-side script. For more information, see the Client.audioSampleAccess and Client.videoSampleAccess properties in Server-Side ActionScript Language Reference for Adobe Flash Media Server. If the source object and (in the case of a Sprite or MovieClip object) all of its child objects do not come from the same domain as the caller, or are not in a content that is accessible to the caller by having called the Security.allowDomain() method, a call to the draw() throws a SecurityError exception. This restriction does not apply to AIR content in the application security sandbox. ...".
For crossdomain file creation and some other security config for AMS server, you can take a look on this post : Crossdomain Video Snapshot - Fixing BitmapData.draw() Security Sandbox Violation.
After allowing our script to get data from our video stream, we can pass to the code.
I wrote a code that play a video stream ( rtmp or http ) and take a snapshot to show it in the stage or save it as a file after applying a pixel effect :
const server:String = null; //'rtmp://localhost/vod'
const stream:String = 'stream'; // 'mp4:big_buck_bunny_480p_h264.mp4';
var nc:NetConnection;
var ns:NetStream;
var video:Video;
const jpg_quality:int = 80;
const px_size:int = 10;
nc = new NetConnection();
nc.addEventListener(AsyncErrorEvent.ASYNC_ERROR, function(e:AsyncErrorEvent):void{});
nc.addEventListener(NetStatusEvent.NET_STATUS, function(e:NetStatusEvent):void{
if(e.info.code == 'NetConnection.Connect.Success'){
ns = new NetStream(nc);
ns.addEventListener(NetStatusEvent.NET_STATUS, function(e:NetStatusEvent):void{});
ns.addEventListener(AsyncErrorEvent.ASYNC_ERROR, function(e:AsyncErrorEvent):void{});
video = new Video(320, 180);
video.x = video.y = 10;
video.attachNetStream(ns);
addChild(video);
ns.play(stream);
}
})
nc.connect(server);
btn_show.addEventListener(
MouseEvent.CLICK,
function(e:MouseEvent): void{
var bmp:Bitmap = pixelate(video, px_size);
bmp.x = 10;
bmp.y = 220;
addChild(bmp);
}
)
btn_save.addEventListener(
MouseEvent.CLICK,
function(e:MouseEvent): void{
var bmp:Bitmap = pixelate(video, px_size);
var jpg_encoder:JPGEncoder = new JPGEncoder(80);
var jpg_stream:ByteArray = jpg_encoder.encode(bmp.bitmapData);
var file:FileReference = new FileReference();
file.save(jpg_stream, 'snapshot_'+int(ns.time)+'.jpg');
}
)
function pixelate(target:DisplayObject, px_size:uint):Bitmap {
var i:uint, j:uint = 0;
var s:uint = px_size;
var d:DisplayObject = target;
var w:uint = d.width;
var h:uint = d.height;
var bmd_src:BitmapData = new BitmapData(w, h);
bmd_src.draw(d);
var bmd_final:BitmapData = new BitmapData(w, h);
var rec:Rectangle = new Rectangle();
rec.width = rec.height = s;
for (i = 0; i < w; i += s){
for (j = 0; j < h; j += s){
rec.x = i;
rec.y = j;
bmd_final.fillRect(rec, bmd_src.getPixel32(i, j));
}
}
bmd_src.dispose();
bmd_src = null;
return new Bitmap(bmd_final);
}
Of course, this is just a simple example to show the manner to get a snapshot from a video stream, you should adapt and improve it to your needs ...
I hope all that can help you.
I'm running a website from a USB drive and trying to pass parameters through the address bar to a new window when a button is clicked in the embedded flash swf.
The problem is that on some workstations the parameters are stripped from the URL. On others it works fine.
I have a movieclip button that when clicked calls this function:
function onReleaseHandler(myEvent:MouseEvent) {
var printURL = "html/certPopup.html";
var request:URLRequest = new URLRequest(printURL);
var variables:URLVariables = new URLVariables();
variables.vModTitle = modTitle;
variables.vFirstName = firstName;
variables.vLastName = lastName;
variables.vLang = language;
request.data = variables;
navigateToURL(request, "_self");
}
On machines where this is working, the certPopup.html page opens in a new tab and the URL in the address bar looks like this:
file:///G:/courses/flash/1/EN/course/html/certPopup.html?vFirstName=Charlie&vModTitle=This%20is%20the%20Title&vLang=EN&vLastName=Brown
On workstations where this is not working the URL in the address bar appears as:
G:\courses\flash\1\EN\course\html\certPopup.html
Browser is IE version 10.0.9200.16540 on all workstations.
Flash version is WIN 11,6,602,180 or higher.
I'm really stumped as to why the URL in the address bar is different on different machines, with the parameters being stripped.
The reason the first works and second doesn't is, that the first one is a URL, the second one is a file path. I have no idea if this might work, but try changing
var printURL = "html/certPopup.html";
to
var printURL = root.loaderInfo.loaderURL.replace(root.loaderInfo.loaderURL.split("/").pop(), ""); + "html/certPopup.html";
But since you are working on an offline project: Why don´t you work with AIR with captive runtime? Would be easier and the possibilities would be much greater?
I'm implementing an Augmented Reality application for android using Flash. In order to get the application working on my Android Phone (nexus One) the Phone Camera must be activated as well. So I need 2 layers one for the background which is the feed of my phone camera and an other one on top of it which is the view from away3d in this case.
So setting up a BitmapData object to hold the information of the most recent webcam still-frame I can make this work.
If I use papervision3D library and FLARToolkit we setting up the BitmapData using the following part of the code found from this video tutorial:
//import libraries
import org.libspark.flartoolkit.core.raster.rgb.FLARRgbRaster_BitmapData;
import org.libspark.flartoolkit.detector.FLARSingleMarkerDetector;
private function setupCamera():void
{
vid = new Video(640, 480);
cam = Camera.getCamera();
cam.setMode(320, 240, 10);
vid.attachCamera(cam);
addChild(vid);
}
private function setupBitmap():void
{
bmd = new BitmapData(640, 480);
bmd.draw(vid);
raster = new FLARRgbRaster_BitmapData(bmd);
detector = new FLARSingleMarkerDetector(fparams, mpattern, 80);
}
private function loop(e:Event):void
{
if(detector.detectMarkerLite(raster, 80) && detector.getConfidence() > 0.5)
{
vp.visible = true;
detector.getTransformMatrix(trans);
container.setTransformMatrix(trans);
bre.renderScene(scene, camera, vp);
}
else{
vp.visible = false}
}
catch(e:Error){}}}}
However, to implement my application Im using Away3D engine and FLARManager and the way of doing that is very different as I can understand. I have implement the following code but the only think it does is just show the Flash Camera in the front of the 3D view and I can't check if my application is work or not since it doesn't show me any 3D Object when I place the marker in front of the screen.
My code is:
//Setting Up Away3DLite Camera3D
import com.transmote.flar.camera.FLARCamera_Away3DLite;
private var camera3D:FLARCamera_Away3DLite;
this.camera3D = new FLARCamera_Away3DLite(this.flarManager, new Rectangle(0, 0, this.stage.stageWidth, this.stage.stageHeight));
//Setting Up the bitmapData
private function bitmap():void
{
c = Camera.getCamera();
c.setMode(320,240,10)
this.v.attachCamera(c);
addChild(this.v);
bmd = new BitmapData(640,480);
bmd.draw(this.v);
}
Can you please help me to find out how can I combine those two?
I will really appreciate any advice i can get from you.
Thank you
To isolate your problem, I'd try to break these two things up and make sure each part works first. It's sounds like you've got the camera part working, try doing just some 3D (no AR) draw a cube or something. Then try implementing the AR but have it do something simple like trace something out or making an object visible or invisible. Then start combining them.
I have a website in ActionScript 3 that has lots of FLV animations that happen when you press buttons. Right now this is how I have it set up.
in AS3,
im loading FLv's (which are animations I exported in FLV form from After Effects)
with net stream. I have a timer set up for the same amount of length of time that the animations (FLV's) play and when the timer stops it calls a function that closes the stream, opens a new one and plays another video. The only problem I noticed using timers is that if the connection is slow and (animation)stops for a second, the timer keeps going, and calls the next flv too early.
Does anyone know a way to load a flv, or swf for that matter, at the end of play of the flv? so that the next FLV will always play at the end of the run time of the previous FLV, rather than using timers?
im thinking onComplete but I don't know how to implement that!?
Sequential playing is pretty easy to achieve with the OSMF framework, you should check it out. Google "osmf tutorials" and you should find a few tutorials online.
The framework is fairly recent, but it looks like it may become the de facto solution for media delivery in Flash as it's not limited to video but also audio & images.
As a developer you won't have to bother with the NetStream & NetConnection classes. Developing video solutions , as well as audio & images solutions should be streamlined and easier to handle. Only limitation is that it requires Flash 10
Here's some code for checking when a FLV ends with NetStream. I just provide snippets as I assume you got the FLV up and running already.
//create a netstream and pass in your connection
var netStream:NetStream = new NetStream(conn);
//add callback function for PlayStatus -event
var client : Object = {};
client.onPlayStatus = onPlayStatus;
netStream.client = client;
//attach your NetStream to the connection as usual
//---
//function that gets called onPlayStatus
function onPlayStatus(info : Object) : void {
trace("onPlayStatus:" +info.code + " " + info.duration);
if (info.code == "NetStream.Play.Complete") {
//play the next FLV and so on
}
}
EDIT: With your example code it will look something like this.
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
var listener:Object = new Object();
listener.onMetaData = function(md:Object):void{};
listener.onPlayStatus = function(info : Object) : void {
trace("onPlayStatus:" +info.code + " " + info.duration);
if (info.code == "NetStream.Play.Complete") {
//play the next FLV and so on
}
};
ns.client = listener;
vid1.attachNetStream(ns);
const moviename1:String = "moviename2.flv";
const moviename1:String = "moviename3.flv";
var movietoplay:String = "moviename.flv";
ns.play(movietoplay);
