See Interfaces.txt for the current list of tested interfaces.
Fixed 1 bug related to 64bit in DsRotEntry.
W7 introduced a number of new interfaces. Most of these had to do with digital TV, but
there were a few that are generally useful:

These interfaces are defined in the library, but most of them are untested.

New in DirectShow .NET 2.0 (Dec 10, 2011)

In this release, we added the new interfaces introduced into DirectShow in Vista. Obviously
these interfaces will only work on Vista.
Defined
Tested
See Interfaces.txt for the current list of tested interfaces.
Not all of the Vista interfaces can be tested, but we have tested the ones for which we have
hardware. The others are included as untested.
We have added the System.Security.SuppressUnmanagedCodeSecurity attribute to the interfaces
as well. This tends to improve performance in interfaces that are called frequently (ie many
times a second). No code change should be required.
We have also corrected problems related 64 bit support. Primarily fixing "pack" problems on
structures, but a few interfaces have been changed to support 64 bit. Primarily changing
parameters from int to IntPtr. This will require code changes where you are using them, but
the changes are relatively obvious, and are easily located with a re-compile.
IMediaEventSink
IMediaEvent
IDVDInfo2
IVideoWindow
IMediaEvent
IMediaEventEx
We have also changed all the IEnumXXX interfaces so that param 3 is an IntPtr rather than
an "out int." This is consistent with Microsoft's implementations, and absolutely essential
for cases where someone needs to *implement* the method, rather than just call it. The places
we have made changes are easily located with a re-compile. If you are using any of these methods,
here's what you'll need to change:
If you are *not* using the value returned by the 3rd parameter, simply replace it with
IntPtr.Zero.
If you *are* using the value returned by the 3rd parameter, you'll need something like this:
IntPtr p = Marshal.AllocCoTaskMem(4);
try
hr = em.Next(monikers.Length, monikers, p);
DsError.ThrowExceptionForHR(hr);
x = Marshal.ReadInt32(p);
finally
Marshal.FreeCoTaskMem(p);
We have also removed a few duplicate definitions. If you were using one of these and we deleted
the one you were using, you'll need to use the other one. The compiler will complain about the
missing definition in your next re-compile.
AtscFilterOptions & ATSCFilterOptions
DsmccFilterOptions & DSMCCFilterOptions
MpegPacketList & MPEGPacketList
MpegRequestType & MPEGRequestType
Mpeg2Filter & MPEG2Filter
MpegWinsock & MPEGWinsock
MpegBcsDemux & BCSDeMux
MpegContext & MPEGContext
MpegStreamBuffer & MPEGStreamBuffer
We have also dropped support for VS2003. Since VS2005 has been out for 2 years now (and is
available for free!), it doesn't seem worth the effort to put time into keeping the vs2003 stuff
active. We haven't (to our knowledge) done anything to the library that will prevent it from working
with 2003, but since none of the dev team still has it installed, we haven't tried it. If you are
still using vs2003, you can check the cvs tree at sourceforge for the old .csproj and .sln files.
And that's about it. Now that MS has stopped development on DirectShow, we may call this library
done. Barring bug fixes, of course.
