问题 I'm trying to implement the following Exif reading library with as3, but I can't load the browsed file. In the library example they use loader.load(new URLRequest("http://www.example.com/sample.jpg")); for loading the image, the problem in my application is that the file is selected by a file-browser in a local computer. I tried a fileReference.name but it doesn't work, the only way that I found to make my test, is putting a file in the same directory than the .swf like this : loader.load(new

The trick is the resulting video needs to be a 'slow motion' version of the captured video. So for example, if someone creates a 2 minute movie, the resulting movie will be 4 minutes. I'd like to build this in Flex / AS3 if possible. I don't have issues capturing the video and storing it / generating and emailing a link, but

I want to use a Cartesian Data Canvas as a background element and draw custom set of background graphics mostly rectangles.
