QR Code reader on Mobile Device...

I'm desperate here -- I have no idea why I can't get this to work, but I really need some help...

I've tried writing a custom QR-Code reader app for iOS and Android, and I can't get any app any where to recognize a QR-Code...

It *seems* to run OK, but it just never decodes any data -- always comes back with "nothing decoded" if it comes back at all...

I've tried the  ZXing library available on Google, and I've tried the one at LibSpark.org.  Neither of them will ever detect a QR-Code, and the ZXing library runs so incredibly slowly that it's useless anyway -- 7 to 10 seconds to process one image and tell me there's no QR-Code in there, when I know full well there is?  Ridiculous!

So, has anyone out there actually gotten a QR-Code reader app to work successfully?  One where you DON'T have to "click" a button to take a picture, but where it will simply scan the video input and will auto-detect when a QR-Code is in the video frame?

If so, I'd REALLY like to ask you how you did it, and even see some source-code if at all possible...

Thanks a bunch!

Hi:

I have updated the Library with new Set of APIs So that,

You can place the Scanner Preview on the Stage(Similar to StageWebView) and have your own UX around it. Also Localize in the way application desires.

Fortunately, there are apps where you can do this, just open playstore or the appstore, then type in search, "qr code scanner" and there will be a lot of apps which all work properly. I tried some of them and they work perfectly.
