CoreMediaIO.CMIOObjectSetPropertyData ValueError

[mansourmoufid]

Describe the bug

Attempting to call CMIOObjectSetPropertyData() raises a ValueError exception:

  File "main.py", line 1028, in cmio_set_property
    status = CoreMediaIO.CMIOObjectSetPropertyData(
ValueError: depythonifying 'pointer', got 'CoreMediaIO.CMIOObjectPropertyAddress'

CMIOObjectGetPropertyData() works fine on the same objectID.

In CoreMediaIO/_metadata.py, I see:

    "CMIOObjectSetPropertyData": (b"iI^{CMIOObjectPropertyAddress=III}I^vI^v",),

and in the same file:

    "CMIOObjectGetPropertyData": (
        b"iI^{CMIOObjectPropertyAddress=III}I^vI^I^v",
        "",
        {
            "arguments": {
                1: {"type_modifier": "n"},
                3: {"c_array_length_in_arg": 2, "type_modifier": "o"},
                5: {"type_modifier": "o"},
                6: {"c_array_length_in_arg": (4, 5), "type_modifier": "o"},
            }
        },
    ),

The two functions have the same signature except for the second to last argument.

I just copy-pasted the tuple for CMIOObjectGetPropertyData into CMIOObjectSetPropertyData, and the exception is gone, it seems to work now.

Platform information

• Python version: 3.8.13

Expected behavior

CMIOObjectSetPropertyData() should return non-zero (fail).

This is due to incomplete metadata. I'm working on a fix (starting with updating the test that should have detected this problem...)

[ronaldoussoren]

I've pushed a fix for this issue.

I'm not sure yet when I'll push out a release with this fix, my plan was to wait for the 3.12 beta release, but that's been postponed so I may release sooner than that.
