# Installing on Windows
|
||
|
||
## Supported platforms
|
||
|
||
* Windows XP
|
||
* Windows Vista
|
||
* Windows 7
|
||
* Windows 8
|
||
|
||
## Prerequisites
|
||
|
||
To develop applications using the GStreamer SDK for Windows you will
|
||
need [Windows
|
||
XP](http://windows.microsoft.com/en-US/windows/products/windows-xp) or
|
||
later.
|
||
|
||
The GStreamer SDK includes C headers (`.h`) and library files (`.lib`)
|
||
valid for any version of [Microsoft Visual
|
||
Studio](http://www.microsoft.com/visualstudio). For convenience,
|
||
property pages (`.props`) are also included which extremely simplify
|
||
creating new projects. These property pages, though, only work with
|
||
[Microsoft Visual
|
||
Studio 2010](http://www.microsoft.com/visualstudio/en-us/products/2010-editions)
|
||
(including the free [Visual C++ Express
|
||
edition](http://www.microsoft.com/visualstudio/en-us/products/2010-editions/visual-cpp-express)).
|
||
|
||
The recommended system is
|
||
[Windows 7](http://windows.microsoft.com/en-us/windows7/products/home)
|
||
with [Microsoft Visual
|
||
Studio 2010](http://www.microsoft.com/visualstudio/en-us/products/2010-editions) (Take
|
||
a look at its [system
|
||
requirements](http://www.microsoft.com/visualstudio/en-us/products/2010-editions/visual-cpp-express)).
|
||
|
||
Installing the SDK for 32-bits platforms requires approximately 286MB of
|
||
free disk space for the runtime and 207MB for the development files.
|
||
|
||
Installing the SDK for 64-bits platforms requires approximately 340MB of
|
||
free disk space for the runtime and 216MB for the development files.
|
||
|
||
## Download and install the SDK
|
||
|
||
There are 3 sets of files in the SDK:
|
||
|
||
- The runtime files are needed to run GStreamer applications. You
|
||
probably want to distribute these files with your application (or
|
||
the installer below).
|
||
- The development files are **additional** files you need to create
|
||
GStreamer applications.
|
||
- The [Merge
|
||
Modules](http://msdn.microsoft.com/en-us/library/windows/desktop/aa369820%28v=vs.85%29.aspx)
|
||
files are **additional** files you can use to deploy the GStreamer
|
||
SDK alongside your application (see [Windows
|
||
deployment](Windows%2Bdeployment.html)).
|
||
|
||
Get **the Runtime and Development files** installers appropriate for
|
||
your architecture from here:
|
||
|
||
**FIXME: Add links **
|
||
|
||
> 
|
||
> Due to the size of these files, usage of a [Download Manager](http://en.wikipedia.org/wiki/Download_manager) is **highly recommended**. Take a look at [this list](http://en.wikipedia.org/wiki/Comparison_of_download_managers) if you do not have one installed. If, after downloading, the installer reports itself as corrupt, chances are that the connection ended before the file was complete. A Download Manager will typically re-start the process and fetch the missing parts.
|
||
|
||
Execute the installers and choose an installation folder. The suggested
|
||
default is usually OK.
|
||
|
||
> 
|
||
>`If you plan to use Visual Studio, **close it before installing the GStreamer SDK**. The installer will define new environment variables which will not be picked up by Visual Studio if it is open.
|
||
|
||
> On **Windows 8** and **Windows 10**, it might be necessary to log out and log back in to your account after the installation for the newly defined environment variables to be picked up by Visual Studio.
|
||
|
||
It is the application's responsibility to ensure that, at runtime,
|
||
GStreamer can access its libraries and plugins. It can be done by adding
|
||
`%GSTREAMER_SDK_ROOT_X86%\bin` to the `%PATH%` environment variable, or
|
||
by running the application from this same folder.
|
||
|
||
At runtime, GStreamer will look for its plugins in the following
|
||
folders:
|
||
|
||
- `%HOMEDRIVE%%HOMEFOLDER%/.gstreamer-1.0/plugins`
|
||
- `C:\gstreamer\1.0\x86\lib\gstreamer-1.0`
|
||
- `<location of libgstreamer-1.0-0.dll>\..\lib\gstreamer-1.0`
|
||
- `%GST_PLUGIN_PATH%`
|
||
|
||
So, typically, if your application can find `libgstreamer-1.0-0.dll`,
|
||
it will find the GStreamer plugins, as long as the installation folder
|
||
structure is unmodified. If you do change this structure in your
|
||
application, then you can use the `%GST_PLUGIN_PATH%` environment
|
||
variable to point GStreamer to its plugins. The plugins are initially
|
||
found at `%GSTREAMER_SDK_ROOT_X86%\lib\gstreamer-1.0`.
|
||
|
||
Additionally, if you want to prevent GStreamer from looking in all the
|
||
default folders listed above, you can set the
|
||
`%GST_PLUGIN_SYSTEM_PATH%` environment variable to point where the
|
||
plugins are located.
|
||
|
||
## Configure your development environment
|
||
|
||
### Building the tutorials
|
||
|
||
The tutorial's code, along with project files and a solution file for
|
||
Visual Studio 2010 are all included in the SDK, in
|
||
the `%GSTREAMER_SDK_ROOT_X86%``\share\gst-sdk\tutorials` folder.
|
||
|
||
`%GSTREAMER_SDK_ROOT_X86%` is an environment variable that the installer
|
||
defined for you, and points to the installation folder of the SDK.
|
||
|
||
In order to prevent accidental modification of the original code, and to
|
||
make sure Visual Studio has the necessary permissions to write the
|
||
output files, copy the entire `tutorials` folder to a place of your
|
||
liking, and work from there.
|
||
|
||
> 
|
||
> **64-bit Users**
|
||
>
|
||
>Use `%GSTREAMER_SDK_ROOT_X86_64%` if you have installed the SDK for 64-bit platforms. Both SDKs (32 and 64-bit) can be installed simultaneously, and hence the separate environment variables.
|
||
>
|
||
>Make sure you select the Solution Configuration that matches the GStreamer SDK that you have installed: `Win32` for 32 bits or `x64` for 64 bits.
|
||
>
|
||
> 
|
||
|
||
You can fire up Visual Studio 2010 and load your copy of the
|
||
`tutorials.sln` solution file (Click on the screen shots to enlarge
|
||
them).
|
||
|
||
|
||
|
||
|
||
|
||
Hit **F7**, press the Build Solution button
|
||
 or go to Build →
|
||
Build Solution. All projects should build without problems.
|
||
|
||
### Running the tutorials
|
||
|
||
In order to run the tutorials, we will set the current working directory
|
||
to `%GSTREAMER_SDK_ROOT_X86%`\\`bin` in the Debugging section of the
|
||
project properties. **This property is not stored in the project files,
|
||
so you will need to manually add it to every tutorial you want to run
|
||
from within Visual Studio**. Right click on a project in the Solution
|
||
Explorer, Properties → Debugging → Working Directory, and type
|
||
`$(GSTREAMER_SDK_ROOT_X86)`\\`bin`
|
||
|
||
(The `$(...)` notation is required to access environment variables
|
||
from within Visual Studio. You use the `%...%` notation from Windows
|
||
Explorer)
|
||
|
||
You should now be able to run the tutorials.
|
||
|
||
### Creating new projects manually
|
||
|
||
**If you want to create 64-bit applications, remember also to create x64
|
||
Solution and Project configurations as
|
||
explained [here](http://msdn.microsoft.com/en-us/library/9yb4317s\(v=vs.100\).aspx).**
|
||
|
||
#### Include the necessary SDK Property Sheet
|
||
|
||
The included property sheets make creating new projects extremely easy.
|
||
In Visual Studio 2010 create a new project (Normally a `Win32
|
||
Console` or `Win32 Application`). Then go to the Property Manager
|
||
(View→Property Manager), right-click on your project and select “Add
|
||
Existing Property Sheet...”. Navigate to
|
||
`%GSTREAMER_SDK_ROOT_X86%`\\`share\vs\2010\libs` and
|
||
load `gstreamer-1.0.props `
|
||
|
||
This property sheet contains the directories where the headers and
|
||
libraries are located, and the necessary options for the compiler and
|
||
linker, so you do not need to change anything else in your project.
|
||
|
||
If you cannot find the Property Manager, you might need to enable Expert
|
||
Settings. Go to Tools → Settings → Expert Settings. Upon first
|
||
installation of Visual Studio, Expert Settings are disabled by
|
||
default.
|
||
|
||
|
||
|
||
> 
|
||
> **Depending on the GStreamer libraries you need to use, you will have to add more property pages, besides `gstreamer-1.0`** (each property page corresponds to one GStreamer library).
|
||
>
|
||
> The tutorial's project files already contain all necessary property pages. When developing your own applications, the GStreamer documentation will tell you what library a function belongs to, and therefore, what property pages you need to add.
|
||
|
||
#### Remove the dependency with the Visual Studio runtime
|
||
|
||
At this point, you have a working environment, which you can test by
|
||
running the tutorials. However, there is a last step remaining.
|
||
|
||
Applications built with Visual C++ 2010 depend on the Visual C++ 2010
|
||
Runtime, which is a DLL that gets installed when you install Visual
|
||
Studio. If you were to distribute your application, you would need to
|
||
distribute this DLL with it (What is known as the [Visual C++ 2010
|
||
Redistributable
|
||
Package](http://www.microsoft.com/download/en/details.aspx?id=5555)).
|
||
This happens with every version of Visual Studio, and the Runtime DLL is
|
||
different for every version of Visual Studio.
|
||
|
||
Furthermore, GStreamer itself is built using a “basic” C runtime which
|
||
comes in every Windows system since Windows XP, and is named
|
||
`MSVCRT.DLL`. If your application and GStreamer do not use the same C
|
||
Runtime, problems are bound to crop out.
|
||
|
||
In order to avoid these issues you must instruct your application to use
|
||
the system's C Runtime. First install the [Windows Device Driver Kit
|
||
Version 7.1.0](http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=11800) (DDK).
|
||
When the installer asks about the features, select only “Build
|
||
Environments”. Accept the suggested location for the installation, which
|
||
is usually `C:\WinDDK\7600.16385.1`. This download is an ISO file, you
|
||
can either burn a DVD with it (as recommended in the Microsoft site. You
|
||
will need DVD burning software), mount the file in a virtual DVD device
|
||
(you will need DVD virtualization software) or unpack the file as if it
|
||
was a regular compressed file (you will need decompression software that
|
||
understands the ISO format).
|
||
|
||
Then, add the `x86.props` or `x86_64.props` (for 32 or 64 bits) property
|
||
sheet found in `%GSTREAMER_SDK_ROOT_X86%``\``share\vs\2010\msvc` to your
|
||
project. This will make your application use the ubiquitous
|
||
`MSVCRT.DLL` saving you some troubles in the future.
|
||
|
||
> 
|
||
> If you did not install the WinDDK to the standard path `C:\WinDDK\7600.16385.1`, you will need to tell Visual Studio where it is. Unfortunately, there is no automated way to do this. Once you have added the `x86.props` or `x86_64.props` to your project, go to the Property Manager, expand your project and its subfolders until you find the property sheet called `config`. Double click to edit it, and select the section called “User Macros” in the list on the left. You should see a macro called `WINDOWS_DRIVER_KIT`. Double click to edit it, and set its value to the root folder where you installed the DDK. This is the folder containing a file called `samples.txt`.
|
||
>
|
||
>That's it. Accept the changes, right click on the `config` property sheet and select “Save”. The path to the DDK is now stored in `config.props` and you do not need to perform this operation anymore.
|
||
|
||
### Creating new projects using the wizard
|
||
|
||
Go to File → New → Project… and you should find a template
|
||
named **GStreamer SDK Project**. It takes no parameters, and sets all
|
||
necessary project settings, both for 32 and 64 bits architectures.
|
||
|
||
The generated project file includes the two required Property Sheets
|
||
described in the previous section, so, in order to link to the correct
|
||
`MSVCRT.DLL`, **you still need to install the Windows Device Driver
|
||
Kit** and change the appropriate property sheets.
