tutorials and vs2017

[David Ing]

The last time I tried to use the VS property sheets was at gstreamer 1.12,
I'm not sure if they have changed since then.

At that time (I was using VS 2015), I determined that some of the property
sheets in here are broken:

%GSTREAMER_1_0_ROOT_X86_64%\x86_64\share\vs\2010\msvc

I believe this broken when Microsoft fractured their CRT into 4 different
libraries which are listed here:
https://docs.microsoft.com/en-us/cpp/c-runtime-library/crt-library-features?view=vs-2019

I eventually determined that the default VS project setup was sufficient to
replace whatever is going on in this folder:

%GSTREAMER_1_0_ROOT_X86_64%\x86_64\share\vs\2010\msvc


Now I am using the 1.14.4 build for Windows (which is a mingw build), and I
mainly consume gst-editing-services and the GstDiscoverer API.  My property
sheet includes the following.

  <ItemDefinitionGroup>
    <ClCompile>

<AdditionalIncludeDirectories>$(GlibIncludeFolder);$(GstreamerIncludeFolder);%(AdditionalIncludeDirectories)</AdditionalIncludeDirectories>
    </ClCompile>
    <Link>

<AdditionalLibraryDirectories>$(GstreamerLibFolder);$(GstreamerDllFolder);%(AdditionalLibraryDirectories)</AdditionalLibraryDirectories>
      <AdditionalDependencies>
*ges-1.0.lib;glib-2.0.lib;gobject-2.0.lib;gstbase-1.0.lib;gstcontroller-1.0.lib;gstpbutils-1.0.lib;gstreamer-1.0.lib;intl.lib;*
%(AdditionalDependencies)</AdditionalDependencies>
    </Link>
  </ItemDefinitionGroup>

One caveat is that I have repackaged the Gstreamer include, *.dll, and
*.lib files into my own folder structure .... but in any case the snippet
shows the set of libraries that I am using.

BTW, I found a windows application called HxD to be a useful tool for
searching the *.lib files for the symbols that I was missing.  It has a
feature where you can search an entire folder.
