Decoding timeout doesn't work on RaspberryPi

I noticed that when I set decoding timeout on my RaspberryPi function decode() exits always after 0.0016s no matter what value I set (different from 0). When timeout is doesn’t set or equals 0 function works fine. This is how I set timeout: code = decode(image=cropped, timeout=1000) OS is rasbian jessie, and python version is 3.6. Does anybody have the same problem? Maybe it’s library fault, not wrapper?

I was having the same issue and it took me some time to find the issue. This post may help anyone facing the same.

The reason is a wrong c structure wrapper in class DmtxTime on Raspberry Pi arm platform. On Raspberry Pi time_t is an long int and therefore can be ctype c_ulong instead of c_ulonglong. Original code from wrapper.py:

class DmtxTime(Structure):
    _fields_ = [
        ('sec', c_ulonglong),      # Actually a time_t
        ('usec', c_ulong),
    ]

Working code on Raspberry Pi:

class DmtxTime(Structure):
    _fields_ = [
        ('sec', c_ulong),      # Actually a time_t
        ('usec', c_ulong),
    ]

Hi @quicklizard99 , I wonder if it is planned to merge the PR (#58) for the next release. It seems that I have the same issue with my raspberry pi and this patch worked correctly for me
