           Summary: mfplay:mfplay - test_media_language() sometimes gets a
                    NULL value in Wine
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW

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.

--- Comment #1 from François Gouget  ---
A bisect confirms that the failures started with the commit below:

commit c97b8a8f1a5df34e3d03c405bda5f76356123da4

mfplay/tests: Add tests for MF_SD_LANGUAGE.

Note: so far the failures have only happened in the GitLab CI, debiant TestBot
VM and my fgtb-debian11 VM. It's not clear why they have not happened in the
TestBot's debian11 and debian11b VMs yet. Luck?
