short-description: Deploy the SDK with your application
|
||
...
|
||
|
||
# Deploying your application
|
||
|
||
Once the development of your application is finished, you will need to
|
||
deploy it to the target machine, usually in the form of a package or
|
||
installer. You have several options here, and, even though this subject
|
||
is not really in the scope of this documentation, we will give some
|
||
hints to try to help you.
|
||
|
||
# Multiplatform vs. single-platform packaging system
|
||
|
||
The first choice you need to make is whether you want to deploy your
|
||
application to more than one platform. If yes, then you have the choice
|
||
to use a different packaging system for each platform, or use one that
|
||
can deliver to all platforms simultaneously. This table summarizes the
|
||
pros and cons of each option.
|
||
|
||
<table>
|
||
<colgroup>
|
||
<col width="33%" />
|
||

|

|

<thead>
|
||
<tr class="header">

||
<th> </th>
|
||
<th>Pros</th>
|
||
<th>Cons</th>

|

</ul></td>
|

|
||
<li>On some platforms, the packaging system might impose artificial restrictions inherited from the other platforms.</li>
|

</ul></td>
|

|

<tr class="even">
|
||

|
||
<p>Your application is packaged using a different system on each platform.</p></td>
|

|

|
||
<p> </p></li>
|
||
</ul></td>
|

|

|

|
||
The GStreamer SDK itself supports three different platforms (Linux, Mac
|
||
OS X and Windows) and has been built using a multiplatform packaging
|
||
system named **Cerbero**, which is available for you to use, should you
|
||
choose to go down this route.
|
||
|
||
# Shared vs. private GStreamer deployment
|
||
|
||
You can install the GStreamer SDK in the target machine in the same way
|
||
you installed it in your development machine, you can deploy it
|
||
privately, or you can even customize it before deploying. Here you have
|
||
a few options:
|
||
|
||
<table>
|
||
<colgroup>
|
||
<col width="33%" />
|
||
<col width="33%" />
|
||

|

</colgroup>
|
||
<thead>
|
||
<tr class="header">
|

<th> </th>
|
||
<th>Pros</th>
|
||
<th>Cons</th>
|
||
</tr>
|
||
</thead>
|
||
<tbody>
|
||
<tr class="odd">
|
||
<td><p><strong>Shared SDK</strong></p>
|
||
<p>The GStreamer SDK is installed independently of your application, as a prerequisite, in a common place in the target computer (<code>C:\Program Files</code>, for example). You application uses an environment variable to locate it.</p></td>
|
||
<td><ul>
|
||
<li><p>If more than one application in the target computer uses the SDK, it is installed only once and shared, reducing disk usage.</p></li>
|
||
</ul></td>
|
||
<td><ul>
|
||
<li>Tampering or corruption of the shared SDK installation can make your application fail.</li>
|
||
<li><p>The SDK libraries are unprotected and open to tampering.</p></li>
|
||
</ul></td>
|
||
</tr>
|
||
<tr class="even">
|
||
<td><p><strong>Private SDK with dynamic linking</strong></p>
|
||
<p>Your application deploys the GStreamer SDK to a private folder.</p></td>
|
||
<td><ul>
|
||

|

</ul></td>
|

|

</ul></td>
|
||
</tr>
|

<tr class="odd">

<td><p><strong>Private SDK with static linking</strong></p>
|

<p>Your application links statically against the GStreamer SDK, so it effectively becomes part of your application binary.</p></td>
|
||
<td><ul>
|
||
<li>Your SDK is independent of other applications, so it does not get corrupted if other applications mess with their installations.</li>
|
||
<li>It is much harder to tamper with the SDK, since it is embedded in your application.</li>
|
||
</ul></td>
|
