| <p> |
| libgstpbutils is a general utility library for plugins and applications. |
| It currently provides the |
| following: |
| </p> |
| <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "> |
| <li class="listitem"><p> |
| human-readable description strings of codecs, elements, sources, decoders, |
| encoders, or sinks from decoder/encoder caps, element names, or protocol |
| names. |
| </p></li> |
| <li class="listitem"><p> |
| support for applications to initiate installation of missing plugins (if |
| this is supported by the distribution or operating system used) |
| </p></li> |
| <li class="listitem"><p> |
| API for GStreamer elements to create missing-plugin messages in order to |
| communicate to the application that a certain type of plugin is missing |
| (decoder, encoder, URI protocol source, URI protocol sink, named element) |
| </p></li> |
| <li class="listitem"><p> |
| API for applications to recognise and handle missing-plugin messages |
| </p></li> |
| </ul></div> |
| <p> |
| You should obtain the required CFLAGS and LIBS using pkg-config on the |
| gstreamer-plugins-base-0.10 module. You will then also need to add |
| '-lgstpbutils-0.10' manually to your LIBS line. |
| </p> |
| <p> |
| Before using any of its functions, applications and plugins must call |
| <a class="link" href="gst-plugins-base-libs-gstpbutils.html#gst-pb-utils-init" title="gst_pb_utils_init ()"><code class="function">gst_pb_utils_init()</code></a> to initialise the library. |
| </p> |
| </div> |

| <div class="refsect1"> |
| <a name="gst-plugins-base-libs-gstpbutils.details"></a><h2>Details</h2> |
| <div class="refsect2"> |
| <a name="gst-pb-utils-init"></a><h3>gst_pb_utils_init ()</h3> |
| <pre class="programlisting"><span class="returnvalue">void</span> gst_pb_utils_init (<em class="parameter"><code><span class="type">void</span></code></em>);</pre> |
| <p> |
| Initialises the base utils support library. This function is not |
| thread-safe. Applications should call it after calling <a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-Gst.html#gst-init"><code class="function">gst_init()</code></a>, |
| plugins should call it from their plugin_init function. |
| </p> |
| <p> |
| This function may be called multiple times. It will do nothing if the |
| library has already been initialised. |
