           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux

mfplay:mfplay - test_media_language() sometimes gets a NULL value in Wine:

mfplay.c:502: Test failed: Unexpected value (null).

See https://test.winehq.org/data/patterns.html#mfplay:mfplay

This would indicate an issue with Wine's GetStreamAttribute(MF_SD_LANGUAGE)
support.

The test was introduced on 2023-01-24 and the first failure happened on
2023-01-25 with a bit over one failure per week since.
