Is it possible to embed YouTube video without CSS3DRenderer in three.js? I'm using cardboard effect, So CSS3DRenderer won't work here.
Here is the code that i used so far. But im facing cross domain issue
video = document.createElement('video');
video.autoplay = true;
video.src = 'http://myurl.com/videos/video.mp4';
newcanvas = document.createElement('canvas');
context = newcanvas.getContext('2d');
videoTexture = new THREE.Texture( newcanvas );
.....
In animate function i have used the below code.
if (video.readyState === video.HAVE_ENOUGH_DATA ){
context.drawImage(video,0, 0);
if(videoTexture)
videoTexture.needsUpdate = true;
}
First you need to embed your youtube video in an html video tag. If you have a look on the internet you'll find a lot of ways for doing this. This may come useful to you: YouTube URL in Video Tag
After having this working you need to convert it to a THREE.Texture, so you can map it to a mesh and use WebGL Renderer. There's a Three.jsextension for this: threex.videotexture
Is not possible in praticle. Youtube.com will not accept any cross domain job with there assets. Only way is to use youtube API with iframe but i make some action to make this possible.
You will need to add server part for you web app. I use nodejs.
This is procedure:
Use classic google , youtube APi login/search
Make search and collect search result data (Most important is videoId )
Save to your own server
Call from web app your new route.
Now you can do what ever you want.

I'm developing a streaming radio in 3D using Three.JS, I'm sending music as a PeerConnection to my clients attaching a THREE.AudioAnalyser() to display 3D bars that move according to frequencies.
Sound is working great in all platforms, but THREE.AudioAnalyser() with an input source of stream type only works on Chrome, Safari is not working at all :frowning:
var listener = new THREE.AudioListener();
var audio = new THREE.Audio( listener );
audio.setMediaStreamSource( stream );
audioAnalyser = new THREE.AudioAnalyser( audio, 128 );
function loop(){
console.log(audioAnalyser.getFrequencyData());
}
The console.log() of the loop() function should contain an Array of Integers, on Chrome is all good, Safari logs [0,0,0,0,0,0,0,0]
What could be causing this issue? It seems to work everywhere but not on Safari, and also it only seems to fail when the source is a stream.
Not 100% sure, but you might want to connect the output of the AnalyserNode to the destination node. You may want to stick a GainNode with a gain of 0 in between, just in case you don't really want the audio from the AnalyserNode to be played out.
I've been trying for two days to find an alternative to loading an image into my current project. I am using Adobe Flash Professional CS6 as my IDE and Animation program. I would like to be able to display an image in my application. What I am trying to do is have the image display onto the screen, the user enters the PLU associated with the image, and if the PLU is right then they receive a point. I have everything else already to go, but I just can't find an efficient way to deal with loading the image.
Right now I'm using this to accomplish getting my image on the display:
var myDisp:Layer0 = new Layer0();
var bmp:Bitmap = new Bitmap(myDisp);
spDispBox.addChild(bmp);
The above code works just find, but the limitation I can't get around is that I'm going to have to import each image into the library and then consecutively code each part in. I wanted to stick to OOP and streamline this process, I just don't know where I should turn to in order to accomplish my project goal. I'm more than happy to give more information. Thanks in advance, everyone.
July, 26, 2014 - Update: I agree, now, that XML is the way to go. I'm just having a hard time getting the grasp of loading an external XML file. I'm following along, but still not quite getting the idea. I understand about creating a new XML data object, Loader, and URLRequest. It's just loading the picture. I've been able to get output by using trace in the function to see that the XML is loaded, but when I go to add the XML data object to the stage I'm getting a null object reference.
I'm going to try a few more things, I just wanted to update the situation. Thanks again everyone.
it seems like these images are in your FLA library. To simplify your code you can make a singleton class which you can name ImageFactory (factory design pattern) and call that when needing an image which will return a Sprite (lighter than a MovieClip)
spDispBox.addChild( ImageFactory.getImageA() ); // returns a Sprite with your image
and in your ImageFactory
public function getImageA():DisplayObject {
var image:Layer0 = new Layer0(); // image from the FLA library
var holder:Sprite = new Sprite();
holder.addChild( new Bitmap( image ) );
return holder;
}
also recommend using a more descriptive name than Layer0
This issue has been following me around for almost a year now, and I want to kill it, for my sake and for the sake of all.
I'm working on some banner ads that need to load in images from a client's site for display. When I tried to do this using AS2, I found out that AS2 doesn't let you do that. It's a bug in the language. There are workarounds for images on the local server, but images loaded from are not allowed to share their BitmapData, so those workarounds don't work. I ended up capitulating after about two months of banging my head against the desk and cursing Macromedia.
Now we are talking about moving to AS3 (finally) and I'm really excited. Or, I was really excited until I started doing some tests for image quality and found that there is very little change in image quality happening here. It's a repeat of my trials with AS2: everything loads perfectly in the IDE, I get all excited, I move the swfs over to the test server to run them online, and POOF - jaggies. Jaggies everywhere.
I've read a number of solutions online, none of which work. They include:
Setting target.content.smoothing to "true". Works great in the IDE. All improvements disappear in the browser.
Setting target.scaleX = target.scaleY to 1.01. It just breaks the swf.
Adding "new LoaderContext(true)" to my parameters for the load command. Does nothing.
Setting target.content.pixelSnapping to "always". Looks perfect in the IDE, not in the browser.
Setting a crossdomain.xml file. The images are showing up - they're being loaded, even if jaggedly, so there must be a functioning crossdomain file on the client's server, right?
So now I'm just stuck, and brokenhearted. Could anyone offer insight on my code, and why it might not be rendering as beautifully as it should be? Here is the client-safe version of the quick demo I am making (only the image URL has been deleted, everything else is as it is now):
import flash.events.Event;
function completeHandler(e:Event) {
e.target.content.pixelSnapping = "always";
e.target.content.smoothing = true;
}
var imgurl:String = "CLIENT'S IMAGE URL HERE";
var imageLoader01:Loader = new Loader();
var image01:URLRequest = new URLRequest(imgurl);
imageLoader01.load(image01);
imageLoader01.contentLoaderInfo.addEventListener(Event.COMPLETE,completeHandler);
addChild(imageLoader01);
imageLoader01.x = 2;
imageLoader01.y = 0;
imageLoader01.scaleX = imageLoader01.scaleY = .6;
var imageLoader02:Loader = new Loader();
var image02:URLRequest = new URLRequest(imgurl);
imageLoader02.load(image02);
imageLoader02.contentLoaderInfo.addEventListener(Event.COMPLETE,completeHandler);
addChild(imageLoader02);
imageLoader02.x = 100;
imageLoader02.y = 80;
imageLoader02.scaleX = imageLoader02.scaleY = .308;
var imageLoader03:Loader = new Loader();
var image03:URLRequest = new URLRequest(imgurl);
imageLoader03.load(image03);
imageLoader03.contentLoaderInfo.addEventListener(Event.COMPLETE,completeHandler);
addChild(imageLoader03);
imageLoader03.x = 200;
imageLoader03.y = 180;
imageLoader03.scaleX = imageLoader03.scaleY = .152;
var bannerLegend:legend = new legend();
addChild(bannerLegend);
Thank you very much in advance. Any help will be sorely appreciated.
Update: Here is the HTML embed code:
<div id="swf_mr_sc_wt_si"></div>
<script type="text/javascript">
<!--
var swfurl = "http://DOMAIN_WITHELD_SORRY/static/AS3.swf?m=DEFAULT&t=" + (new Date().getTime());
swfobject.embedSWF(swfurl, "swf_mr_sc_wt_si", 300, 250, "8.0.0", "");
// -->
</script>
<p>
Hope this helps.
Further Update: We are not listed in the crossdomain.xml file. But we can still load the jagged images. And those images, when loaded into the same swf run in the IDE, are smooth. I think I'm missing understanding of some kind of apocryphal knowledge here, because everything I read points to me being able to do this. This is VERY confusing.
It's because the image you're loading is located on another domain, and that domain's crossdomain.xml does not contain the domain the .swf is residing on, basically giving the .swf "permission" to access the image's pixel data (Yes, just enabling smoothing on an image loaded from another domain requires the same security as when reading the pixel data using BitmapData.draw(), which is a bit curious). When running in local security sandbox the restrictions are more lax, that's why it works running from the IDE.
Even if your domain were among the approved domains in the crossdomain.xml you might need to tell the Flash Player to check the policy file by sending in new LoaderContext(true) as a second argument to Loader.load() when loading the image.
Edit: I originally thought using loadBytes() would be a workaround, but it turns out it's not. I have removed that example code
I'm trying to smooth an scaled image loaded from another website. The image is not animated.
It works well if I use a local image. but it seems not work with images loaded from remote server.
Here is the snippet:
...
//_loader.load(new URLRequest(http://img.example.com/remote.jpg));
_loader.load(new URLRequest("../assets/local.jpg"));
_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, completeHandler);
...
protected function completeHandler(event:Event):void
{
var image:Bitmap = Bitmap(event.target.content);
image.smoothing = true;
image.pixelSnapping = "never";
}
As tested, when I load local.jpg, it works perfect. But when I load remote.jpg from the server, the smoothing param didn't work.
Anyone knows why?
I searched everywhere, but no one has the same problem. I'm not using Flash Professional, it's a pure ActionScript Project built in Flash Builder. And the image is not animating. So wired...
Because you are pulling an image from a remote server you need to set a cross domain policy xml file on the web server where the image is held.
Without this you can't alter bitmaps at a sub pixel level.
Example of:
http://www.senocular.com/pub/adobe/crossdomain/policyfiles.html
More details
http://www.adobe.com/devnet/articles/crossdomain_policy_file_spec.edu.html
I searched day by day, and finally find the answer:
_loader.load( new URLRequest("http:…." , new LoaderContext(true));
The most important is the second param of load() method, it's a LoaderContext. Reference:
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/display/Loader.html#load()
Although I set the crossdomain file in the server, without the "new LoaderContext(true)", it won't read the crossdomain file. That's why it doesn't work at first.
If you have the same problem, hope it's helpful to you!
Is there a javascript library to draw images directly in the browser and save them to png or jpeg?
I want to use an alternative to services like aviary.com, pixlr.com and sumopaint.com and dont want to rely on third-party services and apis like these ones.
Is processingjs the right solution? I want a solution that works everywhere so please no nodejs and so on.
I need tools like a brush, paintbrush, pencil, layers, filters and so on - just like the real photoshop.
You could also draw all sorts of images and animations using http://paperjs.org/
Then you can save them using straightforward JS:
var canvas = document.getElementById("my_canvas_element");
var imageToExport = canvas.toDataURL("image/jpeg");
document.write('<img src="'+img+'"/>');
Try processingjs
For image saving, just use data-urls:

Get image data in JavaScript?
