saving webcam image to a website
How can i save a webcam screenshot to a website?
I know you can save it to your hard drive using:
var browseFileReference = new FileReference();
browseFileReference.save(video);
But how would 开发者_StackOverflowi go about it to save this image to a website, lets say flickr or facebook or something.
Any help?
You should have a look at existing AS3 library.
Flickr : http://code.google.com/p/as3flickrlib/
Facebook : http://www.adobe.com/devnet/facebook.html
The basic steps are, generate the bitmap data for the region you want, use one of the F/OSS libraries to generate PNG or JPEG data, base64 the data, and then generate a URLRequest with the encoded image as POST data, which can hen be handled server side. I would have to dig through projects to find the proper classes I have to do this to show a real example, but this is actually really simple. Each of the steps I outline can be implemented in a few lines of code using existing libraries.
You can save the screenshot of the webcam as ByteArray. Make sure you have the JPGEncoder class (from the as3corelib).
// bitmapdata
var btmData:BitmapData = new BitmapData(video.width, video.height);
btmData.draw(video);
// make jpg
var jpgEncoder:JPGEncoder = new JPGEncoder(90);
var jpgBytes:ByteArray = jpgEncoder.encode(btmData);
Now, you can use the as3flickrlib to connect with Flickr. Danny Patterson wrote a nice article to upload a ByteArray to Flickr with this library, see http://blog.dannypatterson.net/2009/08/upload-bytearray-to-flickr/
Edit: I would first try to upload it to Facebook, that is much easier than uploading an image to Flickr.
