Bug ID: 51104
           Summary: mf:mf crashes on Windows + NVidia
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: mfplat
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

mf:mf crashes on the cw-gtx560 and cw-rx460 machines but not on the TestBot VMs
(except w7u-2qxl, but that's a different crash).

https://test.winehq.org/data/patterns.html#mf:mf

The crash happens on the same test_evr() line from Windows 8.1 to Windows 10
2009:

hr = MFGetService((IUnknown *)stream_sink2, &MR_VIDEO_ACCELERATION_SERVICE,
&IID_IMFVideoSampleAllocator,
            (void **)&allocator);

A bisect shows that the commit causing the crash is not the one that added this
line but the one below:
