Decoding error when calling summary.Summary() #103

Closed emile-lochner closed 5 days ago

emile-lochner commented 4 months ago

I use mgz as part of a website that analyses uploaded games. Last successful upload was 2024-03-13 17:39:26 UTC (in case they changed something on AoE2's side). I have attached the recording file. It can be played using CaptureAge so I an fairly sure the file is not corrupt. test_recording.zip

Test script:

from mgz.summary import Summary
fpath = ".../test_recording.aoe2record"

with open(fpath, 'rb') as data:
    s = Summary(data)

Traceback:

could not fast parse; falling back: could not parse:

The latest patch is not yet supported.

I guess there is still no support for the latest patch :(

happyleavesaoc commented 5 days ago

Fixed in mgz-1.8.26
