I have the following code:
ActionScript Code:
_camera = Camera.get();
_camera.setMode(320, 180, 12, false);
_video.attachVideo(_camera); //attaching to Video object
[Code]....
2) why is the image from the camera so small? It doesn't fill the 320x180 white background, it's size is actually 160x120. Is this some Flash limitation or how exactly did it get to this size?
I'm trying to modify the alpha layer of a bitmapData by taking a source iamge and masking out areas that don't have the correct channel. ATM I'm using copyChannel to achieve the effect, but I'd liek more than 3 channels (use alpha kills the other channels it seems). 255, 0, 255 should be able to act as another mask.
This is what I'm doing now...
Code:
bitmap.bitmapData.copyChannel(tempMask, new Rectangle(0, 0, tempMask.width, tempMask.height), new Point(0, 0), BitmapDataChannel.RED, BitmapDataChannel.ALPHA);
So the red parts of the image mask out the source image. All I want is to be able to mask out things basic on multiple channels (the lesser of the 2).
1) How does copyChannel work? Can I just test each pixel manually and achieve relatively similar speeds? and 2) if the Flash inline functions are infact faster, is there a function that can do what I want, or would it be better to use a shader?
Code:
var tempBitmapData:BitmapData = new BitmapData(tempMask.width, tempMask.height);
var matrix:Array = [];
matrix = matrix.concat([0, 0, 0, 0, 0]); // red
matrix = matrix.concat([0, 0, 0, 0, 0]); // green

I am trying to create a BitmapData object of a jpg that is loaded into a movieClip, so that I can then remove the jpg and have just the BitmapData of the image to manipulate. I have the original image loading into my temporary MC without any problems..and am using a listener to check to make sure that the image has been fully loaded before it moves onto creating an empty movie clip for the BitmapData... but for some reason the BitmapData isn't working as nothing shows up in my holderMC.. and it says the width of the holderMC is 0 when it should be something liek 367 for the 'surf.jpg' test image I am using. My code is below..
Code:
import flash.display.BitmapData;
stop();
_root.createEmptyMovieClip("tempMC", 1, {_alpha:0});

currently I use the following workflow for Live video streaming.I have FMLE on a computer streaming the Video feed to my FMS.I currenlty use Dreamweaver to create window with a few instances of a video window and one of the windows is configured to rtmp to my server and the stream name of the stream I have setup in FMLE.This then streams to one of the windows.I then assign a different Stream name to the other windows.
I send an FMLE client to a user in the locations that want to have a video presence on the webpage.I send them instructions and running FMLE and the parameters to use to get their camera up and running.This works fine to a point.Most of the users are not technically minded and so often this leads to issues and delays to get these things to work.
I want to move on and improve this flow.I want to create the video instances on the page where:Below each video window is a text input field where a user can type in their name which will be used as the stream name.Below each video window is a button that the user clicks to connect their camera automatically without having to install FMLE.Once the video feed is running, only that user can click the button again to disconnect it. ( The button changes to "Stop Broadcast" etc).
I have looked at the structure of Ustream for example, and this seems to be the method they use as you can download the XML file of your channe,l and the RTMP URL and stream name can be copied and then used directly in FMLE and you can stream with more control of your camera that way.
I have the following code

I am capturing camera on flex for android using air 3.1,and found that the camera is only showing the a part of of actual camera video.When i view camera using normal camera application in android galaxy tab, it shows full camera area but when i am capturing the camera in flex its showing only the center area for it.I tried using setMode to set the resolution, but its not of any use.Is there any way to get full camera area captured inside flex using camera.getCamera ?
View 1 RepliesFrom a Flash object, I would like to be able to detect the presence of a webcam that the user might grant access to, without actually asking the user whether they want to grant access. This is to streamline a large application that has extra features if a webcam exists — if there is a webcam, the application will present several dialogs that lead up to the normal cam-security prompt, but if the user doesn't have the hardware, I want to skip over them altogether. Requesting access to the cam before those dialogs won't make sense to the user.
It appears not to be possible to call Camera.getCamera() without the security prompt happening. Is there a workaround? (For instance, could I, perhaps, call getCamera in a hidden Flash object and inspect its return value, or does it block until the user acknowledges the security prompt?)
I have a video capture device on a machine. I have written a windows application to capture the video from this device. While capturing, if i try to broadcast using flash it does not connect. If i'm already broadcasting and then try to capture then my windows application does not get the capture pin of the device. So, flash seems to be taking the capture pin. Is there anyway to broadcast using the preview pin on the device so that i can capture using my application. Or is there way where i can split the capture pin and give one to my app and one to the broadcaster

btw, first I used assigned thumbContainer as the mc argument (outside the loadThumbs() function) and it worked but not exactly what I wanted... because I thought it is supposed to update when the movieclip is animated but it actually didn't... when I use a scroller, only the thumbs that are first loaded to the stage get the reflection..
I've been using BitmapData.copyPixels() to draw graphics onto a canvas (Bitmap).I need to rotate the resulting graphics without the use of draw() because it's vastly slower.How can I rotate the target graphic? I'm assuming that there might be a formula or library that I can use which will first reorganize the pixels that make up a graphic based on an origin (point) and radians.I'm pretty certain that I'm not capable of creating such logic, so if there are any known libraries that do this, that would be awesome.I'd like to achieve something similar to XNA's SpriteBatch.Draw() method, which accepts rotation as its 5th argument.

I am having an issue with using BitmapData.draw(stage). I am getting the following error:
SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: file:///C|/Documents%20and%20Settings/bla...bla...bla.swf cannot access null. No policy files granted access. Here is a portion of my code:

The title might be a little misleading. Look at my code and I will explain
public static function loadTile(tileDir:String = "empty"):void
{
if(tileDir != "empty")
{
tPoint = new Point(0,0);
tRect = new Rectangle(0,0,30,30);
[Code]...
I am trying to do tiling with sprites. I want my tiles to be interactive, so that is why I am using the sprite object instead of using regular bitMaps to represent my tiles. You might be wondering why I wouldnt just use graphics.beginBitmapFill(tImage); and graphics.drawRect(0, 0,tWidth ,tHeight ); to pick out the tiles I want to use. Well reason being is because it turns out that drawRect() first and second parameters actually alter the location of where the actual sprite sits at.
So if I set the x and y properties of the sprite to x = 20, and y = 20. then I set my drawRect(20,20). it actually adds an extra 20 pixels to my x and y coords of my sprite. And I know the reason why, I just need to know a better way.
I have a problem with the camera slowing down in my project.I thought it could be because of the complexity and memory consumtion of this work, so I created a completely new movie, typed such code:
quote:
var camera:Camera = Camera.getCamera();
var video = new Video(camera.width, camera.height);
video.attachCamera(camera);
addChild(video);
[code]....
And... this time the camera's fps stayed 25fps all the time. To be honest - I really don't know why :| I mean, I'm happy the fps stayed stabily at the level, but I don't know what to do in the mentioned, complex, project to make the fps faster. I can't just add the trace line.

I am on macbook pro and my camera doesnt show on the stage. I had a video object there named 'video' i also at some point had the imports for Camera and Video, still no luck. What am I doing wrong. I am sure I had this at some point in the past.
I just have a problem when a point goes *behind* the camera: if point.z < 0. It's ok if there's an MC that just becomes invisible - but if I try to draw a line to this point with the drawingAPI, the point's screen x/y coordinates are weird. I can't figure out how to modify the scaleRatio to get correct values. Here's a code snippet:
var scaleRatio = focalLength/(focalLength + z);
screen_x = x * scaleRatio;
screen_y = y * scaleRatio;
