GstPlugin

GStreamer is extensible, so GstElement instances can be loaded at runtime. A plugin system can provide one or more of the basic GStreamer GstPluginFeature subclasses.

A plugin should export a symbol gst_plugin_desc that is a struct of type GstPluginDesc. the plugin loader will check the version of the core library the plugin was linked against and will create a new GstPlugin. It will then call the GstPluginInitFunc function that was provided in the gst_plugin_desc.

Once you have a handle to a GstPlugin (e.g. from the GstRegistry), you can add any object that subclasses GstPluginFeature.

Usually plugins are always automatically loaded so you don't need to call gst_plugin_load explicitly to bring it into memory. There are options to statically link plugins to an app or even use GStreamer without a plugin repository in which case gst_plugin_load can be needed to bring the plugin into memory.

Methods

gst_plugin_add_dependency

gst_plugin_add_dependency (GstPlugin * plugin,
                           const gchar ** env_vars,
                           const gchar ** paths,
                           const gchar ** names,
                           GstPluginDependencyFlags flags)

Make GStreamer aware of external dependencies which affect the feature set of this plugin (ie. the elements or typefinders associated with it).

GStreamer will re-inspect plugins with external dependencies whenever any of the external dependencies change. This is useful for plugins which wrap other plugin systems, e.g. a plugin which wraps a plugin-based visualisation library and makes visualisations available as GStreamer elements, or a codec loader which exposes elements and/or caps dependent on what external codec libraries are currently installed.

Parameters:

plugin

a GstPlugin

env_vars ( [allow-none][arrayzero-terminated=1])

NULL-terminated array of environment variables affecting the feature set of the plugin (e.g. an environment variable containing paths where to look for additional modules/plugins of a library), or NULL. Environment variable names may be followed by a path component which will be added to the content of the environment variable, e.g. "HOME/.mystuff/plugins".

paths ( [allow-none][arrayzero-terminated=1])

NULL-terminated array of directories/paths where dependent files may be, or NULL.

names ( [allow-none][arrayzero-terminated=1])

NULL-terminated array of file names (or file name suffixes, depending on flags) to be used in combination with the paths from paths and/or the paths extracted from the environment variables in env_vars, or NULL.

flags

optional flags, or GST_PLUGIN_DEPENDENCY_FLAG_NONE

G_END_DECLS

This macro needs to be used to define the entry point and meta data of a plugin. One would use this macro to export a plugin, so that it can be used by other applications.

The macro uses a define named PACKAGE for the GstPluginDesc,source field. When using autoconf, this is usually set automatically via the AC_INIT macro, and set in config.h. If you are not using autoconf, you will need to define PACKAGE yourself and set it to a short mnemonic string identifying your application/package, e.g. 'someapp' or 'my-plugins-foo.

If defined, the GST_PACKAGE_RELEASE_DATETIME will also be used for the GstPluginDesc,release_datetime field.

Parameters:

major

major version number of the gstreamer-core that plugin was compiled for

minor

minor version number of the gstreamer-core that plugin was compiled for

name

short, but unique name of the plugin

description

information about the purpose of the plugin

init

function pointer to the plugin_init method with the signature of static gboolean plugin_init (GstPlugin * plugin).

version

full version string (e.g. VERSION from config.h)

license

under which licence the package has been released, e.g. GPL, LGPL.

package

the package-name (e.g. PACKAGE_NAME from config.h)

origin

a description from where the package comes from (e.g. the homepage URL)

Since : 1.2


GST_PLUGIN_STATIC_REGISTER

#define GST_PLUGIN_STATIC_REGISTER(name) G_PASTE(gst_plugin_, G_PASTE(name, _register)) ()

Parameters:

name

short, but unique name of the plugin

GstPluginInitFullFunc

gboolean
(*GstPluginInitFullFunc) (GstPlugin * plugin,
                          gpointer user_data)

A plugin should provide a pointer to a function of either GstPluginInitFunc or this type in the plugin_desc struct. The function will be called by the loader at startup. One would then register each GstPluginFeature. This version allows user data to be passed to init function (useful for bindings).

Parameters:

plugin

The plugin object

user_data

extra data

Returns

TRUE if plugin initialised successfully


Gst.PluginInitFullFunc

function Gst.PluginInitFullFunc(plugin: Gst.Plugin, user_data: Object): {
    // javascript wrapper for 'GstPluginInitFullFunc'
}

A plugin should provide a pointer to a function of either Gst.PluginInitFunc or this type in the plugin_desc struct. The function will be called by the loader at startup. One would then register each Gst.PluginFeature. This version allows user data to be passed to init function (useful for bindings).

Parameters:

plugin (Gst.Plugin)
