<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p><a class="el" href="classGst_1_1Registry.html" title="Gst::Registry - Abstract base class for management of Gst::Plugin objects.">Gst::Registry</a> - Abstract base class for management of <a class="el" href="classGst_1_1Plugin.html" title="Gst::Plugin - Container for features loaded from a shared object module.">Gst::Plugin</a> objects. </p>
<p>One registry holds the metadata of a set of plugins. All registries build the GstRegistryPool.</p>
<p>Design:</p>
<p>The <a class="el" href="classGst_1_1Registry.html" title="Gst::Registry - Abstract base class for management of Gst::Plugin objects.">Gst::Registry</a> object is a list of plugins and some functions for dealing with them. Gst::Plugins are matched 1-1 with a file on disk, and may or may not be loaded at a given time. There may be multiple <a class="el" href="classGst_1_1Registry.html" title="Gst::Registry - Abstract base class for management of Gst::Plugin objects.">Gst::Registry</a> objects, but the "default registry" is the only object that has any meaning to the core.</p>
<p>The registry.xml file is actually a cache of plugin information. This is unlike versions prior to 0.10, where the registry file was the primary source of plugin information, and was created by the gst-register command.</p>
<p>The primary source, at all times, of plugin information is each plugin file itself. Thus, if an application wants information about a particular plugin, or wants to search for a feature that satisfies given criteria, the primary means of doing so is to load every plugin and look at the resulting information that is gathered in the default registry. Clearly, this is a time consuming process, so we cache information in the registry.xml file.</p>
<p>On startup, plugins are searched for in the plugin search path. This path can be set directly using the GST_PLUGIN_PATH environment variable. The registry file is loaded from ~/.gstreamer-$GST_MAJORMINOR/registry-$ARCH.xml or the file listed in the GST_REGISTRY env var. The only reason to change the registry location is for testing.</p>
<p>For each plugin that is found in the plugin search path, there could be 3 possibilities for cached information:</p>
<ul>
<li>the cache may not contain information about a given file.</li>
<li>the cache may have stale information.</li>
<li>the cache may have current information.</li>
</ul>
<p>In the first two cases, the plugin is loaded and the cache updated. In addition to these cases, the cache may have entries for plugins that are not relevant to the current process. These are marked as not available to the current process. If the cache is updated for whatever reason, it is marked dirty.</p>
<p>A dirty cache is written out at the end of initialization. Each entry is checked to make sure the information is minimally valid. If not, the entry is simply dropped.</p>
<p>Implementation notes:</p>
<p>The "cache" and "default registry" are different concepts and can represent different sets of plugins. For various reasons, at init time, the cache is stored in the default registry, and plugins not relevant to the current process are marked with the GST_PLUGIN_FLAG_CACHED bit. These plugins are removed at the end of intitialization. </p>
