Create GStreamer plugin in VisualStudio 2015

[David Ing]

I did some preliminary plugin development on VS 2015, so I can probably
help you out with that.


After VS 2010 the MSVC Runtime was fractured into a bunch of separate libs,
so things have changed which prevents the VS 2010 property sheets from
working properly.  If you are using VS 2015 then you want to avoid all of
the property sheets in the installation folder ...

%GSTREAMER_1_0_ROOT_X86_64%\share\vs\2010\msvc

... where my environment variables are:

GSTREAMER_1_0_ROOT_X86_64=C:\dev\gstreamer\%GST_VERSION%\x86_64
GST_VERSION=1.14.3

Fortunately, all of the property sheets in the following folder work fine:

%GSTREAMER_1_0_ROOT_X86_64%\share\vs\2010\libs


Here is an example of a property sheet that works with VS 2015 (where I am
consuming gst-editing-services):

https://github.com/adaviding/gstreamer-playground/blob/master/ges-slide-composition/props/x86_64.props


I'm not sure if the following clauses are really necessary if you simply
allow visual studio to include the default property sheets for a given
build.

Under Debug:  <AdditionalDependencies
>libucrtd.lib;libcmtd.lib;libvcruntimed.lib;libcpmtd.lib;msvcprtd.lib;%(AdditionalDependencies)</
AdditionalDependencies>

Under Release:  <AdditionalDependencies
>libucrt.lib;libcmt.lib;libvcruntime.lib;libcpmt.lib;msvcprt.lib;iphlpapi.lib;%(AdditionalDependencies)</
AdditionalDependencies>


In the example above, I made the mistake of starting from the VS 2010
property sheets under the "msvc" folder and then I fixed what was broken
(it wasn't easy).  If I were to do it over, I would just start with a
normal VS 2015 C++ project and include at least the following property
sheets (for plugin development):

gstreamer-1.0.props

gstreamer-base-1.0.props

gstreamer-pbutils-1.0.props

I believe that by including the property sheets above, you will resolve the
error regarding GST_PLUGIN_DEFINE and VERSION.

If you run into linker errors (can't find a particular symbol) then try
searching the *.lib files for that symbol (perhaps I was using a hex
editor, or perhaps I was using the `grep` command from GitBash ... I can't
remember).  Once you figure out which *.lib file defines the given symbol
then you can find the property sheet that goes with that *.lib file, and
include it into your project.
