i have tried add equalizer my online radio. i was used http://www.everyday3d.com/blog/index.php/2008/03/26/classic-sound-equalizer-in-flashas3/
flash source file . it's working fine when i am worked in flash ide. but on my server the equalizer doesnot show. but if the playing file is mp3 format it will worked but if we play the stream url it's not working. i dont know how can i fix this. i am using as3, i am new to flash. please help any one. thanks advance
the equalizer code
var es:EqualizerSettings = new EqualizerSettings();
es.numOfBars = 80;
es.height = 30;
es.barSize = 3;
es.vgrid = true;
es.hgrid = 2;
es.colorManager = new GradientBarColor(0xffff4444);
es.effect = EqualizerSettings.FX_REFLECTION;
var e:Equalizer = new Equalizer();
e.update(es);
e.x = 100;
e.y = 60;
addChild(e);
addEventListener(Event.ENTER_FRAME, e.render);
What Gio said, SoundMixer.computeSpectrum-based approach, such as the one linked in your question, suffers from security problems. But there are alternatives, for example check this code: http://wonderfl.net/c/euIb/read (some of stream URLs in it are dead, and it might not work right away - so try it with your own stream URL)

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.
To free my webcam I'm using
onScrenVideo.attachCamera(null)
where onScreenVideo is a Video object.
However, this just doesn't seem to work. Even after this line executes, the webcam light remains ON.
I have scoured the Internet for a solution to this problem and everyone seems to be unanimous that this is the only way to turn the webcam off (for example : Close webcam usage via actionscript), however, this just doesn't seem to be working for me.
Can anyone help?
Thanks
Edit: Adding relevant code.
All the variables are declared previously. Here's the code to set up the Camera and attach it to the video.
testCurrCam = Camera.getCamera();
onScreenVideo = new Video(240, 180);
onScreenVideo.smoothing = true;
onScreenVideo.x = 0;
onScreenVideo.y = 0;
addChild(onScreenVideo);
testCurrCam.setQuality(0, 70);
testCurrCam.setMode(640, 480, 10);
onScreenVideo.attachCamera(testCurrCam);
And here's a function which is called by Javascript using ExternalInterface. The call works perfectly fine, because I've checked using an alert box after the if condition.
private function stopCam(): void {
if (contains(onScreenVideo)) {
onScreenVideo.attachCamera(null);
this.removeChild(onScreenVideo);
onScreenVideo = null;
testCurrCam = null;
} else
return;
}
I am doing an Adobe AIR Kiosk app but I am having a little problem.
First step is to generate a webcam container:
var bandwidth:int = 0;
var quality:int = 100;
var camera:Camera = Camera.getCamera();
camera.setQuality(bandwidth, quality);
camera.setMode(885,575,30,true);
var video:Video = new Video(885,575);
video.attachCamera(camera);
video.name = "camara";
webcam.addChild(video);
It works ok, the problem is that I want to apply to it a custom filter
It works ok if I write it this way:
MovieClip(parent).contenedor_postal.postal.webcam.filters = [filter];
But I want to affect only the child inside the clip "webcam" without affecting other MC's, so I write it like this:
MovieClip(parent).contenedor_postal.postal.webcam.camara.filters = [filter];
and does not work. I used to program in AS2, so maybe the trick is very simple but I can't find anything that works. Thanks in advance!
If the video has a name property "camara" then this should work:
MovieClip(parent).contenedor_postal.postal.webcam.getChildByName("camara").filters = [filter];
I am creating dynamic TextFields in actionscript 3.0. Like many others, my text disappears when I set .embedFonts = true;
ArialSlim is embedded and exported for actionscript. I have successfully tested with trace(Font.enumerateFonts());
Interestingly enough, when I comment out the embed line (as shown below), the font works properly.
Alternatively, .setTextFormat(); also works properly without the .embedFonts line.
So my questions is, why? Will I run into any issues in this case?
var divArray = new Array();
var x_Lbl_Array:Array = new Array();
var entries:int = 10;
var labelFormat:TextFormat = new TextFormat();
var arial:Font = new ArialSlim();
labelFormat.font = arial.fontName;
labelFormat.size = 10;
var xVar:int = 0;
for(var loop:int = 0; loop < entries; loop++){
x_Lbl_Array[loop] = new TextField();
//x_Lbl_Array[loop].embedFonts = true;
x_Lbl_Array[loop].antiAliasType = AntiAliasType.NORMAL;
x_Lbl_Array[loop].defaultTextFormat = labelFormat;
x_Lbl_Array[loop].x = xVar;
x_Lbl_Array[loop].y = 165;
x_Lbl_Array[loop].text = "test";
mc.addChild(x_Lbl_Array[loop]);
xVar++;
}
Edit:
I just ran this code from frame 1 with .embedFonts = true; and it worked...
Maybe I should mention that I'm having trouble running this code in a method inside an instantiated actionscript class. The class is located in an external .as file. Does this help answer my question?
I tried your code and it worked for me (with the embedded font)
check if you have all the characters included.
You can either set the character range, or create a textfield that has all the characters.
It turns out that I at some point clicked "TLF (DF4)" in the outline format options for my embedded font. When I corrected this, and chose "Classic (DF3)," it fixed my problem.
I guess what I find to be really weird is that the font was showing properly without .embedFonts being set to true
Thank you, Daniel. I appreciate the help.
For a project I want to show all available webcams and microphones, so that the user can easily select whichever webcam/microphone combination they prefer. I run into an issue with the microphones listing though.
Each microphone is listed with an activity animation and it's name. I am able to list all Microphones just fine (using the Microphone.names Array), but it seems like I can only get the activity viewer to work for one microphone. The other microphones show up with '-1' activity, which (as far as I know) is Flex for 'present, but not in use'. When unplugging the microphone that does show activity, the next one (in my case, the mic-in line on my motherboard) shows up with '0' activity (it's not connected, so that makes sense).
During my testing I have a total of 3 microphones available, the not-connected onboard mic-in port, and two connected microphones.
For testing purposes I use a timer that traces the current microphone activity each 100ms and the graph is also shown.
It does not seem to matter what default microphone I set via flash' settings panel.
The code
I've only attached the revelant code snippets below to make it easier for you to read through them. Please let me know if you prefer the entire code.
Main application.mxml
Note: cont is a VBox. i is defined before this code snippet.
var mics:Array = Microphone.names;
for(i=0; i < mics.length; i++){
var mic:settingsMicEntry = new assets.settingsMicEntry;
mic.d = {name: mics[i], index: i};
cont.addChild(mic);
}
assets/settingsMicEntry.mxml
timer is defined before this code snippet. the SoundTransform is added to silence local microphone playback. Excluding this code does not solve the problem, sadly (I've tried). display is an MXML Canvas object.
mic = Microphone.getMicrophone(d.index);
if(mic){
// Temporary: The Microphones' visualizer
var bar:Box = new Box();
bar.y = 50;
bar.height = 0;
bar.width = 66;
bar.setStyle("backgroundColor", 0x003300);
display.addChild(bar);
var tf:SoundTransform = new SoundTransform(0);
mic.setLoopBack(true);
mic.soundTransform = tf;
timer = new Timer(100);
timer.addEventListener(TimerEvent.TIMER, function(e:TimerEvent):void{
var h:int = Math.floor((display.height/100)*mic.activityLevel);
bar.height = (h>-1) ? h : 0;
bar.y = (h>-1) ? display.height-h : display.height;
trace('TIMER: '+h+' from '+d.name);
});
timer.start();
}
I'm pulling my hear out here, so any help is much appreciated!
Thanks,
-Dave
Ps.: Pardon the messiness of the code!
You can set up a mock NetStream connection using the OSMF library.
You'll need to import the classes from the NetMocker project (under libs/adobe - org.osmf.netmocker) and the classes NetConnectionCodes and NetStreamCodes (under framework/OSMF - org.osmf.net).
Check out that you need to create one NetStream for each microphone
