ActionScript 2.0 :: Webcam Color Scan Detection And Play Connected Sound
Oct 7, 2009
I'm working on a school project that will work so that a webcam can scan a grid of colors and determine what color it is and there by playing a sound that is connected to that color. You can then create music by drawing different colors on a grid.
So I managed to import the webcam image to flash, and that's all. How do I Proceed?
* How do I get the webcam to detect colors? (Green, Blue, Red, Yellow and Black)
* How do I connect these color detections to start playing a sound/movieclip?
This is the code id used to import the webcam.
Code:
import flash.media.Camera;
import flash.media.Video;
var camera:Camera = Camera.getCamera();
if (camera != null) {
video.attachCamera(camera);
} else {
trace("You need a camera.");
}
I would like to ask that how can I use the webcam in AS2 for brightness/darkness detection.I've found many topics in motion detection, but they are not useful for me, and they are too complex.hat I want is only an image with alpha level which is react with the light in the room. If the webcam get a dark image (the light are turned off in the room)The alpha of the image goes to 0
I'm currently trying to use flash8 and my webcam to do something similar to [URL] I've just started playing with camera scripts and therefore am stuck with quite alot of problems. But i decided to go on step by step. First problem i met, I am unable to display the snapshot of my webcam into a movieclip.. As in i want to take a frame of my webcam input and draw it into a movieclip.. (so i can compare with later frames to see if there is any motion.) Anyone can help me out here? What is wrong with my script? It's just supposed to take the webcam image on every enterframe and input it to my movieclip right beside my live input of my webcam.. But it appears as a blank MC..
I have this code in my application: ActionScript Code: this.cam = Camera.getCamera(); trace("webcam:", this.cam, this.cam.name); The problem is, the "trace" ALWAYS displays [object Camera] <camera name>, no matter if my webcam is plugged or not. How can I detect if a webcam is not plugged?
I need help with a small flash project i'm doing. Basically the task is to detect a color via webcam, then respond to what colors it can see (using the webcam). Example Color red is held in front of camera - flash sees this, then respond by playing a sound. green and red is held in front of cam, flash can tell there is two colors, plays a sound. etc would writing the webcam video object to a BMD every frame, then getPixel that to work out the colors? I'm guessing i'd need to use colorTransform to merge all the blues, reds, greens, etc together (so it only checks for those 3) then responds if it finds them with getpixel?
is there any examples of that, or something similar i could work from? would anyone be able to give a quick write up of what this might looklike/how to do it? (havent done much programming in as3) All i need it to do is: Check video for range of colours (ie, blue, light blue, dark blue, etc, all are equal to blue, unsure how i'd do this. Was thinking Yellow, Red, Green, Blue as the 4 colours) If any of those are in the video, then respond by playing a sound. (However if yellow and blue are in the video at the same time, play a DIFFERENT tune)
I have a bitmap with many colors inside it. I want each color, when clicked, to preform a different method. How do I determine the pixel's color value and use it for a mouse event? I found bitmap hit detection but I cannot figure out how to use it (because I have many colors inside the bitmap).
I'm having trouble trying to get my sound to only play once if it hits test object. As of now, if the mc remains in contact with the hto then the sound continues to play over and over. What I really need is for the sound to play once and only play again if the mc is moved off of the hto and then back on. Btw, it is a car and a building. Here is what I have so far:
i try to get a bytearray from a webcam. i can get the image of the webcam, copy it to bitmapdata and get the bytearray. but is it possible to get the bytearray from the image and sound from the client's webcam?
So i found a code on the adobe site which pics up input from the mic. I need that to trigger a video when it hits a certain volume. I'm a complete novice to AS3 and i need this for a proof of concept in the morning. Here's the code that i'm using to pick up the mic -
I'm trying to make an instrument type thing.[URL]... How come the sounds play about half a second after you hover your mouse on one of the circles? I need it to be completely instant.
[Code]...
Also, sometimes, it just doesn't detect the hover at all and doesn't play a sound (if you hover too fast)..
It's possible to play a sound file through AS, either by loading it from a folder or import it to flash. It's also possible to play a dynamic tone with flash.media.Sound + writeFloat.
But... is it possible to play a sound file with flash.media.Sound + writeFloat in some way? I want to play a sound file without having to deal with any files except the .swf!
i want to make a single button to play a sound, and if pressed again, stop the sound. and if pressed again, play the sound, and so on... i know it has to be made with a boolean variable, true/false, but i just can't figure out how.
the question is,a client which can use "rtmfp" to connect to a FMS server,and the connecting success,Whether Can not guarantee that the client can play the Multicast video? because the client may be behind a Special firewall So he may connect to the FMS server ,but can not use P2P to connect to the members those are in the group?
If the answer is "yes",Whether i should make a check function that make these client back to "RTMP"?
I'm trying to record video from the users webcam and play it back at a later date. I call
[Code]...
However, when I look at the FMS Admin Console at the streams in app/_definst_, their types are either "NetStream" or "Live". If they were being saved wouldn't they say "Stored"? After I close the application doing the recording, the "NetStream" type stream disappears, and after a while all the "Live" typed streams are gone too. Nothing is saved.
I have no idea what is happening. I don't know if it's a problem with my AS3 code not closing the recording properly or if I'm doing something else wrong, or maybe somethgin isn't right in the FMS?
how to work out the direction of the mouse on stage and say from this:
"if the mouse goes from the left to right (visa-versa) once, add score +1" and "if the mouse speed which is player controlled - slows down - to then display an error graphic"
I'm trying to add sound to some buttons. It's just a little metallic 'klink' sound that plays on rollover. I only want the sound to play on the 'Over' state. So I've set up a layer (just for sound) for the button and I add my sound in the 2nd frame (the Over state). Everything is cool. All is good. And the sound plays on rollover. But the sound also plays when I click the button (i.e. it also plays on the "Down" state). Why? The Down state keyframe is completely empty. What's going on here? I've only put the sound in the "Over" keyframe, why does it also play in the "Down" frame (or when I click)?
I know this doesn't have a simple answer, but I want to learn how to scan images, and thus videos (frame-by-frame) and identify other images in that initial image with a given amount of error.
When I first open my project, I want the visuals to stay on the 1st frame, while Flash scans through and creates an array of all the frame labels and their relative frame numbers.
Would be useful to be able to specify a layer to search for labels on, and/or search for any and all frame labels in an mc.
I want the flash movie to scan the dir, like: news/ In news i have a few txt. files:
[Code]...
I want it to return a array [1.txt,2.txt,3.txt] But when i ad one. news/4.txt it automaticly returns an array with [1.txt,2.txt,3.txt,4.txt] in it. how would i do this?
Is there any as3 based source code that accomplishes pitch detection or beat detection accurately? Doesn't have to be both, if you know of at least one of those,
I want to use a sound loop in my flash movie. The movie has many scenes. And the problem is that when I go to next scene or different scene I hear the sound repeating twice. I mean sound does not stop from first scene and begins from the different scenes.Is there any way to play sound like "stop all sound" option in Flash.
I have to play a sound file and show the progress of the sound file being played. I am using import flash.media.Sound; import flash.media.SoundChannel; But the PROGRESS event gives theprogress of loading of file. I want to know of much of the song has been played and how much more is left.
While recursive scans are commonly use to scan through nested objects / data. It can go on an infinite loop, if some of the objects references one another. So what is the most effective way to scan all items, without crashing the computer, nor skipping a specified parameter?
Here is an example of a recursive scanner...
/** * Triggers the scan function for each object given **/ function recursiveScanner( object:* , scanFunction:Function ):void {
[Code].....
The objects will trigger scans for one another in an eternal loop.
I do believe in C/C++ : Each scanFunction call, will be added into a list consisting of scanned 'memory address', thus preventing a repeat. Is this even possible in AS3? Is there a more elegent way?
