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: wine-bugs@winehq.org
          Reporter: fgouget@codeweavers.com
      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:
commit 430c179fe86dd7f9b3ddfb6ef30f6359633ef0b8
