Implementing support for MFPlat.dll and MFReadWrite.dll

[Alexandre Bique]

Hi,

I'm trying to make Ableton Live works better with wine, and as stated
in this bug: https://bugs.winehq.org/show_bug.cgi?id=35105 setting
wine version to win8 will make Ableton Live crash.

I first though that it was an issue with the OpenFileDialog being
replaced by IFileDialog because it was something that changed and it
was visible, but after second thought, I'm thinking about something
else.

I noticed that ableton tries to load these libraries:

err:module:import_dll Library MFReadWrite.dll (which is needed by
L"C:\users\Public\Application Data\Ableton\Live 9
Suite\Program\VideoExportMMF.dll") not found
err:module:import_dll Library MFPlat.DLL (which is needed by
L"C:\users\Public\Application Data\Ableton\Live 9
Suite\Program\VideoExportMMF.dll") not found

and they're part of Microsoft Media Foundation ...

And just after IFileDialog returns with valid data, the application
crash and we can see on the output:

fixme:commdlg:IServiceProvider_fnQueryService Interface

So what do you think? Is MFPlat.dll and MFReadWrite.dll a good
candidate? If so, how to implement the library? What are the
guidelines?

Thanks and happy Christmas,

How do you guess by that output that it's about some MF*.dll?
is e07010ec-bc17-44c0-97b0-46c7c95b9edc related?
I don't know how things behave with missing interfaces, but i guess the app get's a NULL pointer back and tries to call a function from that object.
(so an easy test hack would be to stub an interface like that somewhere else and see what happens)

Guidelines can be found in the documentation.
You can also use git to see how new dlls are built up. e.g. b03d07dff4d710d9176602a7d939c94bf7dd89ff
