Windows deployment
This page explains how to deploy GStreamer along your application. There are different mechanisms, which have been reviewed in . The details for some of the mechanisms are given here, and more options might be added to this documentation in the future.
Shared GStreamer
This is the easiest way to deploy GStreamer, although most of the time it installs unnecessary files which grow the size of the installer and the target drive free space requirements. Since GStreamer might be shared among all applications that use it, though, the extra space requirements are somewhat blurred.
Simply pack GStreamer runtime installer (the same one you
installed in your development machine)
inside your installer (or download it from your installer) and execute
it silently using msiexec. msiexec is the tool that wraps most of
the Windows Installer functionality and offers a number of options to
suit your needs. You can review these options by
executing msiexec without parameters. For example using 1.8.1:
msiexec /i gstreamer-1.0-x86-1.8.1.msi
This will bring up the installation dialog as if the user had
double-clicked on the msi file. Usually, you will want to let the user
choose where they want to install GStreamer. An environment variable will
let your application locate it later on.
Private deployment of GStreamer
You can use the same method as the shared GStreamer, but instruct its
installer to deploy to your application’s folder (or a
subfolder). Again, use the msiexec parameters that suit you best. For
example:
msiexec /passive INSTALLDIR=C:\Desired\Folder /i gstreamer-1.0-x86-1.8.1.msi
This will install GStreamer to C:\Desired\Folder showing a progress
dialog, but not requiring user intervention.
Deploy only necessary files, by manually picking them
On the other side of the spectrum, if you want to reduce the space requirements (and installer size) to the maximum, you can manually choose which GStreamer libraries to deploy. Unfortunately, you are on your own on this road, besides using the Dependency Walker tool to discover inter-DLL dependencies.
Bear in mind that GStreamer is modular in nature. Plug-ins are loaded depending on the media that is being played, so, if you do not know in advance what files you are going to play, you do not know which DLLs you need to deploy.
Deploy only necessary packages, using provided Merge Modules
If you are building your installer using one of the Professional editions of Visual Studio or WiX you can take advantage of pre-packaged Merge Modules. GStreamer is divided in packages, which roughly take care of different tasks. There is the core package, the playback package, the networking package, etc. Each package contains the necessary libraries and files to accomplish its task.
The Merge Modules are pieces that can be put together to build a larger Windows Installer. In this case, you just need to create a deployment project for your application with Visual Studio and then add the Merge Modules for the GStreamer packages your application needs.
This will produce a smaller installer than deploying the complete GStreamer, without the added burden of having to manually pick each library. You just need to know which packages your application requires.

If you include a merge module in your deployment project, remember to include also its dependencies. Otherwise, the project will build correctly and install flawlessly, but, when executing your application, it will miss files.
