Yep, I've used Zbar for barcode detection in photographs before. It wasn't particularly fast for my usage, but a lot of the photos I was scanning weren't particularly well cropped around the bar code. I'd be interested in seeing some benchmarks between this approach and Zbar. Also, a ton of the barcode scanning mobile apps use zbar as well (they all use zbar's default interface unchanged).
