cfd68a8e7a
Builds with MSVC, not tested in MinGW or anything else. Added COM handling code, borrowed from dshowvideosink. Moved Linux specific files to ./linux and added Windows specific files to ./win (generated from IDL files in VS9). Added macros to handle BSTR and defined bool as BOOL. Fixes #655362.
