Barcode scanning doesn't work due to incomplete EGL in Replicant.  See
this bug report:

http://redmine.replicant.us/issues/681

which is a duplicate of:

http://redmine.replicant.us/issues/705

My needs for a QR scanner is only inside Yubico Authenticator (similar
to Google Authenticator, but with HMAC keys stored on a YubiKey NEO
rather than on the phone) and my workaround has been to use Yubico
Authenticator Desktop on my laptop, or a (sigh) CyanogenMod phone to do
the QR scanning.

I earlier had the idea of a barcode scanner that would scan photos
instead of reading from the preview image.  Replicant can take photos
reliably.  Does anyone know of any app that can barcode/qr scan from a
photo?
