gstdec 'StructureWrapper' object has no attribute 'get_int'

[wargreen]

Hi, and thanks for your tools !

When trying to import a flac files via beets, i got

beet import -m ./Estradasphere/
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/audioread/gstdec.py", line 262, in _notify_caps
    self.channels = info.get_int('channels')[1]
                    ^^^^^^^^^^^^
AttributeError: 'StructureWrapper' object has no attribute 'get_int'

I can search for more information if needed.

I hit the same issue using Debian 13 6.12.74 with Python 3.13.5, GStreamer 1.26.2, audioread 3.0.1-2

The fix is non-trivial: StructureWrapper has no public API at all in the current GStreamer Python bindings - get_int(), get_value(), and [] indexing all fail

The working fix is to unwrap the private attribute: info._StructureWrapper__structure.get_value('channels')

Accessing a name-mangled private attribute is not ideal, so a proper fix may need a different approach...
