Good decoding:

```json
{
"ok": false,
"desc": "file decoding error: image: unknown format",

}
```

# Build and Run

Download and compile ZBar for shared dependencies:

```bash
wget https://downloads.sourceforge.net/project/zbar/zbar/0.10/zbar-0.10.tar.bz2
# or, if you are suffering decoding troubles on UTF-8, try this modified version:
# wget https://github.com/nanmu42/zbar-utf8/archive/master.zip
tar -xf zbar-0.10.tar.bz2
cd zbar-0.10
export CFLAGS=""
./configure --disable-video --without-imagemagick --without-qt --without-python --without-gtk --without-x --disable-pthread
make install
```
