--- Comment #1 from Alexandr Oleynikov sashok.olen@gmail.com --- Still an issue with 5.0-rc5 0009:fixme:amstream:ddraw_IDirectDrawMediaStream_GetFormat (02DF148C)->(0032F418,00000000,00000000,0032F41C) stub! I tried to change the return value here https://github.com/wine-mirror/wine/blob/master/dlls/amstream/ddrawstream.c#... to S_OK (which in the success return value according to these docs https://technet.microsoft.com/ru-ru/evalcenter/dd406809(v=vs.113) ) but it didn't help, so I guess it actually needs to be implemented.
