# Download and install the SDK
|
||
|
||
The GStreamer SDK provides a set of binary packages for supported Linux
|
||
distributions. Detailed instructions on how to install the packages for
|
||
each supported distribution can be found below. Optionally, you can
|
||
download the source code and build the SDK yourself, which should then
|
||
work on any platform.
|
||
|
||
These packages will install the SDK at `/opt/gstreamer-sdk`. If you
|
||
build the SDK yourself, you can install it anywhere you want.
|
||
|
||
Ubuntu (Click here to expand)
|
||
|
||
In order to install the SDK on **Ubuntu**, it is required that the
|
||
public repository where the SDK resides is added to the apt sources
|
||
list.
|
||
|
||
To do so, download the appropriate definition file for your
|
||
distribution:
|
||
|
||
- Ubuntu Precise Pangolin (12.04)
|
||
[i386](http://www.freedesktop.org/software/gstreamer-sdk/data/packages/ubuntu/precise/i386/gstreamer-sdk.list) [amd64](http://www.freedesktop.org/software/gstreamer-sdk/data/packages/ubuntu/precise/amd64/gstreamer-sdk.list)
|
||
|
||
- Ubuntu Quantal Quetzal (12.10)
|
||
[i386](http://www.freedesktop.org/software/gstreamer-sdk/data/packages/ubuntu/quantal/i386/gstreamer-sdk.list) [amd64](http://www.freedesktop.org/software/gstreamer-sdk/data/packages/ubuntu/quantal/amd64/gstreamer-sdk.list)
|
||
|
||
- Ubuntu Raring Ringtail (13.04)
|
||
[i386](http://www.freedesktop.org/software/gstreamer-sdk/data/packages/ubuntu/raring/i386/gstreamer-sdk.list) [amd64](http://www.freedesktop.org/software/gstreamer-sdk/data/packages/ubuntu/raring/amd64/gstreamer-sdk.list)
|
||
|
||
And copy it to the `/etc/apt/sources.list.d/` directory on your system:
|
||
|
||
```
|
||
sudo cp gstreamer-sdk.list /etc/apt/sources.list.d/
|
||
```
|
||
|
||
After adding the repositories, the GPG key of the apt repository has to
|
||
be added and the apt repository list needs to be refreshed. This can be
|
||
done by
|
||
running:
|
||
|
||
```
|
||
wget -q -O - http://www.freedesktop.org/software/gstreamer-sdk/sdk.gpg | sudo apt-key add -
|
||
sudo apt-get update
|
||
```
|
||
|
||
Now that the new repositories are available, install the SDK with the
|
||
following command:
|
||
|
||
```
|
||
sudo apt-get install gstreamer-sdk-dev
|
||
```
|
||
|
||
Enter the superuser/root password when prompted.
|
||
|
||
Debian (Click here to expand)
|
||
|
||
In order to install the SDK on **Debian**, it is required that the
|
||
public repository where the SDK resides is added to the apt sources
|
||
list.
|
||
|
||
To do so, download the appropriate definition file for your
|
||
distribution:
|
||
|
||
- Debian Squeeze (6.0)
|
||
[i386](http://www.freedesktop.org/software/gstreamer-sdk/data/packages/debian/squeeze/i386/gstreamer-sdk.list)
|
||
[amd64](http://www.freedesktop.org/software/gstreamer-sdk/data/packages/debian/squeeze/amd64/gstreamer-sdk.list)
|
||
|
||
- Debian Wheezy (7.0)
|
||
[i386](http://www.freedesktop.org/software/gstreamer-sdk/data/packages/debian/wheezy/i386/gstreamer-sdk.list)
|
||
[amd64](http://www.freedesktop.org/software/gstreamer-sdk/data/packages/debian/wheezy/amd64/gstreamer-sdk.list)
|
||
|
||
And copy it to the `/etc/apt/sources.list.d/` directory on your system:
|
||
|
||
```
|
||
su -c 'cp gstreamer-sdk.list /etc/apt/sources.list.d/'
|
||
```
|
||
|
||
After adding the repositories, the GPG key of the apt repository has to
|
||
be added and the apt repository list needs to be refreshed. This can be
|
||
done by
|
||
running:
|
||
|
||
```
|
||
su -c 'wget -q -O - http://www.freedesktop.org/software/gstreamer-sdk/sdk.gpg | apt-key add -'
|
||
su -c 'apt-get update'
|
||
```
|
||
|
||
Now that the new repositories are available, install the SDK with the
|
||
following command:
|
||
|
||
```
|
||
su -c 'apt-get install gstreamer-sdk-dev'
|
||
```
|
||
|
||
Enter the superuser/root password when prompted.
|
||
|
||
Fedora (Click here to expand)
|
||
|
||
In order to install the SDK on **Fedora**, it is required that the
|
||
public repository where the SDK resides is added to the yum sources
|
||
list.
|
||
|
||
To do so, download the appropriate definition file for your
|
||
distribution:
|
||
|
||
- [Fedora 17](http://www.freedesktop.org/software/gstreamer-sdk/data/packages/fedora/gstreamer-sdk.repo)
|
||
|
||
- [Fedora 18](http://www.freedesktop.org/software/gstreamer-sdk/data/packages/fedora/gstreamer-sdk.repo)
|
||
|
||
And copy it to the `/etc/yum.repos.d/` directory on your system:
|
||
|
||
```
|
||
su -c 'cp gstreamer-sdk.repo /etc/yum.repos.d/'
|
||
```
|
||
|
||
After adding the repositories, the yum repository list needs to be
|
||
refreshed. This can be done by running:
|
||
|
||
```
|
||
su -c 'yum update'
|
||
```
|
||
|
||
Now that the new repositories are available, install the SDK with the
|
||
following command:
|
||
|
||
```
|
||
su -c 'yum install gstreamer-sdk-devel'
|
||
```
|
||
|
||
Enter the superuser/root password when prompted.

|
||
# Configure your development environment
|
||
|
||
When building applications using GStreamer, the compiler must be able to
|
||
locate its libraries. However, in order to prevent possible collisions
|
||
with the GStreamer installed in the system, the GStreamer SDK is
|
||
installed in a non-standard location `/opt/gstreamer-sdk`. The shell
|
||
script `gst-sdk-shell` sets the required environment variables for
|
||
building applications with the GStreamer SDK:
|
||
|
||
``` bash
|
||
/opt/gstreamer-sdk/bin/gst-sdk-shell
|
||
```
|
||
|
||
The only other “development environment” that is required is
|
||
the `gcc` compiler and a text editor. In order to compile code that
|
||
requires the GStreamer SDK and uses the GStreamer core library, remember
|
||
to add this string to your `gcc` command:
|
||
|
||
```
|
||
`pkg-config --cflags --libs gstreamer-1.0`
|
||
```
|
||
|
||
If you're using other GStreamer libraries, e.g. the video library, you
|
||
have to add additional packages after gstreamer-1.0 in the above string
|
||
(gstreamer-video-1.0 for the video library, for example).
|
||
|
||
If your application is built with the help of libtool, e.g. when using
|
||
automake/autoconf as a build system, you have to run
|
||
the `configure `script from inside the `gst-sdk-shell` environment.
|
||
|
||

|
||
<tbody>
|
||
<tr class="odd">
|
||
<td><img src="images/icons/emoticons/information.png" width="16" height="16" /></td>
|
||
<td><p>You have also the option to embed the SDK's path into your binaries so they do not need to be executed from within the <code>gst-sdk-shell</code>. To do so, add these options to gcc:</p>
|
||
<div class="code panel" style="border-width: 1px;">
|

<div class="codeContent panelContent">
|
||
<pre class="theme: Default; brush: plain; gutter: false" style="font-size:12px;"><code>-Wl,-rpath=/opt/gstreamer-sdk/lib `pkg-config --cflags --libs gstreamer-1.0`</code></pre>
|
||
</div>
|
||
</div>
|
||
<p>In case you are using libtool, it will automatically add the <code>-Wl </code>and<code> -rpath</code> options and you do not need to worry about it.</p></td>

|
||
|
||
### Getting the tutorial's source code
|
||
|
||
The source code for the tutorials can be copied and pasted from the
|
||
tutorial pages into a text file, but, for convenience, it is also
|
||
available in a GIT repository and distributed with the SDK.
|
||
|
||
The GIT repository can be cloned with:
|
||
|
||
```
|
||
git clone git://anongit.freedesktop.org/gstreamer-sdk/gst-sdk-tutorials
|
||
```
|
||
|
||
Or you can locate the source code in
|
||
`/opt/gstreamer-sdk/share/gst-sdk/tutorials`, and copy it to a working
|
||
folder of your choice.
|
||
|
||
### Building the tutorials
|
||
|
||
You need to enter the GStreamer SDK shell in order for the compiler to
|
||
use the right libraries (and avoid conflicts with the system libraries).
|
||
Run `/opt/gstreamer-sdk/bin/gst-sdk-shell` to enter this shell.
|
||
|
||
Then go to the folder where you copied/cloned the tutorials and
|
||
write:
|
||
|
||
```
|
||
gcc basic-tutorial-1.c -o basic-tutorial-1 `pkg-config --cflags --libs gstreamer-1.0`
|
||
```
|
||
|
||
Using the file name of the tutorial you are interested in
|
||
(`basic-tutorial-1` in this example).
|
||
|
||
<table>
|
||
<tbody>
|
||
<tr class="odd">
|
||
<td><img src="images/icons/emoticons/warning.png" width="16" height="16" /></td>
|
||
<td><p><strong>Depending on the GStreamer libraries you need to use, you will have to add more packages to the <code class="western">pkg-config </code>command, besides <code class="western">gstreamer-1.0</code></strong></p>
|
||
<p>At the bottom of each tutorial's source code you will find the command for that specific tutorial, including the required libraries, in the required order.</p>
|
||
<p>When developing your own applications, the GStreamer documentation will tell you what library a function belongs to.</p></td>
|
||
</tr>
|
||
</tbody>
|
||
</table>
|
||
|
||
### Running the tutorials
|
||
|
||
To run the tutorials, simply execute the desired tutorial (**from within
|
||
the `gst-sdk-shell`**):
|
||
|
||
``` c
|
||
./basic-tutorial-1
|
||
```
|
||
|
||
### Deploying your application
|
||
|
||
Your application built with the GStreamer SDK must be able locate the
|
||
GStreamer libraries when deployed in the target machine. You have at
|
||
least a couple of options:
|
||
|
||
If you want to install a shared SDK, you can put your application
|
||
in `/opt/gstreamer-sdk` (next to the SDK) and create a `.desktop` file
|
||
in `/usr/share/applications` pointing to it. For this to work without
|
||
any problems you must make sure that your application is built with
|
||
the `-Wl,-rpath=/opt/gstreamer-sdk/lib` parameter (this is done
|
||
automatically by libtool, if you use it).
|
||
|
||
Or, you can deploy a wrapper script (similar to `gst-sdk-shell`), which
|
||
sets the necessary environment variables and then calls your application
|
||
and create a `.desktop` file in `/usr/share/applications` pointing to
|
||
the wrapper script. This is the most usual approach, doesn't require the
|
||
use of the `-Wl,-rpath` parameters and is more flexible. Take a look
|
||
at `gst-sdk-shell` to see what this script needs to do. It is also
|
||
possible to create a custom wrapper script with
|
||
the `gensdkshell` command of the Cerbero build system, if you built
|
||
the SDK yourself as explained above.
