myGBPVR: use XMBC as GBPVR FrontEnd

[carpeVideo]

I have found the following format in .Net that should be fine: "''yyyy'-'MM'-'dd'T'HH': 'mm': 'ss.fffffff'zzz' " where "zzz" should be the offset from GMT(in hours/minutes). I will be able to specify that from Python, so I'm hoping that will be fine....

Could you give me the TZ and regional settings for youre GBPVR machine? I can then configure my own server that way and see if the above would work....

It is set for central time zone with daylight savings
(UTC -6) Central Time (US & Canada)

I'll also try the extension stuff , I brute forced it by having it try several extensions. Your solution is much better L:O)

Can I assume that you have XBMC set to the same timezone? That's what I'll be trying intitally then...

I didn't even know you could set XBMC to a different timezone/region setting I just assume it takes that from the machine.

The correct time is the Credential time string and Credential time converted, the now Time was wrong and I did check both Server/Client they both matched the Credential time. The time zone was also correct on both Server and Client, I removed the "T" seems to fix it for now..:-)

Thanks

Hi,

Finally found it! It was a dual problem.... EWA expects a UTC time in the authentication object and the .Net parsing routines resolve a time in non-iso format to the current locale... So if you specified it in the same manner as the current locale, things would be fine...

The final fix is to change "GBPVR_Connect.py" and change the timeSting assignment (in _AddAuthentication) to:

Code:

TimeString = DateTime.utcnow().strftime("%Y-%m-%dT%H:%M:%S")

This change broke my script canniot connect to GPPVR error.

Works - timeString = DateTime.utcnow().strftime("%Y-%m-%dT%H:%M:%S")
Don't Work - timeString = datetime.now().strftime("%m/%d/%Y %H:%M:00")

thanks

Sorry my last post I have it backwarded.

Don't Work - timeString = DateTime.utcnow().strftime("%Y-%m-%dT%H:%M:%S")
Works - timeString = datetime.now().strftime("%m/%d/%Y %H:%M:00")

thanks

What's your timezone? I have tried this with US Central (GMT -6) and the mm/dd/yy format that is nomal in the US. I would also appreciate a dump from the EWA log.... (that should tell us what's going wrong)....

Hey Ton,

I found a pure Python module that does AES encryption and have been attempting to get myGBPVR to work on my original XBoxes with XBMC.

I've got as far as (I think) correctly encrypting the credentials and passing them in the requests, but I'm getting errors from GBPVR with regards to "Padding", so I'm guessing something isn't quite right.

Would you be willing to take a look at that for me? Or even take a look at using the Python module instead of using PyCrypto?

The module is at http://code.google.com/p/slowaes/source/...unk/python

My (poor) code to replace the _AESEncrypt routine is:

Code:

def _AESEncrypt(self, clear_bytes, key_bytes, iv_bytes):

    import aes

    try:        

        mode = aes.AESModeOfOperation.modeOfOperation["CBC"]
        
        key_bytes = map(ord, key_bytes)
        key_size = len(key_bytes)        

        clear_bytes = aes.append_PKCS7_padding(clear_bytes)
        
        iv_bytes = map(ord, iv_bytes)

        aes_cypher = aes.AESModeOfOperation()        
        (mode, orig_len, encrypted) = aes_cypher.encrypt(clear_bytes,mode,key_bytes,key_size,iv_bytes)

        return ''.join(map(chr, encrypted))

    except:
        import traceback
        traceback.print_exc()
        return

Cheers,

Martyn

Hey Ton,

I persevered with this and got it to work:

Code:

def _AESEncrypt(self, clear_bytes, key_bytes, iv_bytes):

    import aes

    try:
        mode = aes.AESModeOfOperation.modeOfOperation["CBC"]
        
        key_bytes = map(ord, key_bytes)
        key_size = len(key_bytes)
        assert key_size in aes.keySize.values(), 'invalid key size: %s' % key_size

        clear_bytes = aes.append_PKCS7_padding(clear_bytes)
        
        iv_bytes = map(ord, iv_bytes)

        aes_cypher = aes.AESModeOfOperation()        
        (mode, orig_len, encrypted) = aes_cypher.encrypt(clear_bytes,mode,key_bytes,key_size,iv_bytes)
        
        return ''.join("%c" % i for i in encrypted)
        
    except:
        import traceback
        traceback.print_exc()
        return

myGBPVR on original XBox XBMC rocks!!
