## Prerequisites
|
||||
|
||||
To develop applications using the GStreamer SDK on Linux you will need
|
||||
one of the following supported distributions:
|
||||
|
||||
- Ubuntu Precise Pangolin (12.04)
|
||||
- Ubuntu Quantal Quetzal (12.10)
|
||||
- Ubuntu Raring Ringtail (13.04)
|
||||
- Debian Squeeze (6.0)
|
||||
- Debian Wheezy (7.0)
|
||||
- Fedora 17
|
||||
- Fedora 18
|
||||
|
||||
Other distributions or version might work, but they have not been
|
||||
tested. If you want to try, do it at your own risk\!
|
||||
GStreamer is included in all Linux distributions. We recommend using the latest version of a fast moving distribution such as Fedora, Ubuntu (non-LTS), Debian sid or OpenSuse to get a recent GStreamer release.
|
||||
|
||||
All the commands given in this section are intended to be typed in from
|
||||
a terminal.

Make sure you have superuser (root) access rights to install the GStreamer SDK.
|
||||
|
||||
## Download and install the SDK
|
||||
## Install GStreamer on Fedora
|
||||
|
||||
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:
|
||||
Run the following command:
|
||||
|
||||
```
|
||||
sudo cp gstreamer-sdk.list /etc/apt/sources.list.d/
|
||||
dnf install gstreamer1-devel gstreamer1-plugins-base-tools gstreamer1-devel-docs gstreamer1-plugins-base-devel gstreamer1-plugins-base-devel-docs gstreamer1-plugins-good gstreamer1-plugins-good-extras gstreamer1-plugins-ugly gstreamer1-plugins-ugly-devel-docs gstreamer1-plugins-bad-free gstreamer1-plugins-bad-free-devel gstreamer1-plugins-bad-free-extras
|
||||
```
|
||||
|
||||
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:
|
||||
## Install GStreamre on Ubuntu or Debian
|
||||
|
||||
```
|
||||
wget -q -O - http://www.freedesktop.org/software/gstreamer-sdk/sdk.gpg | sudo apt-key add -
|
||||
sudo apt-get update
|
||||
```
|
||||
Run the following command:
|
||||
|
||||
Now that the new repositories are available, install the SDK with the
|
||||
following command:
|
||||
` apt-get install .... `
|
||||
|
||||
```
|
||||
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/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 '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 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

||||
```

|
||||
|
||||
#### 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.
