#include <gst/gst.h> GstSchedulerFactory; gboolean gst_scheduler_register (GstPlugin *plugin, const gchar *name, const gchar *longdesc, GType type); GstSchedulerFactory* gst_scheduler_factory_new (const gchar *name, const gchar *longdesc, GType type); void gst_scheduler_factory_destroy (GstSchedulerFactory *factory); GstSchedulerFactory* gst_scheduler_factory_find (const gchar *name); GstScheduler* gst_scheduler_factory_create (GstSchedulerFactory *factory, GstElement *parent); GstScheduler* gst_scheduler_factory_make (const gchar *name, GstElement *parent); void gst_scheduler_factory_set_default_name (const gchar *name); const gchar* gst_scheduler_factory_get_default_name (void);
A schedulerfactory is used to create instances of a scheduler. It can be added to a GstPlugin as it extends GstPluginFeature.
Use gst_scheduler_factory_new()
to create a new scheduler which can be registered
to a plugin with gst_plugin_add_feature()
.
Use gst_scheduler_factory_find()
to find the named schedulerfactory.
or use gst_scheduler_factory_get_list()
to get a list of all available schedulers.
Once an schedulerfactory has been obtained use gst_scheduler_factory_create()
to
instantiate a real scheduler. Optionally gst_scheduler_factory_make()
to create
a scheduler from the named factory.
Use gst_scheduler_factory_destroy()
to remove the factory from the global list.
gboolean gst_scheduler_register (GstPlugin *plugin, const gchar *name, const gchar *longdesc, GType type);
Registers a scheduler with GStreamer.
plugin : | a GstPlugin |
name : | name of the scheduler to register |
longdesc : | description of the scheduler |
type : | GType of the scheduler to register |
Returns : | TRUE, if the registering succeeded, FALSE on error. |
Since 0.8.5
GstSchedulerFactory* gst_scheduler_factory_new (const gchar *name, const gchar *longdesc, GType type);
Create a new schedulerfactory with the given parameters
name : | name of schedulerfactory to create |
longdesc : | long description of schedulerfactory to create |
type : | the gtk type of the GstScheduler element of this factory |
Returns : | a new GstSchedulerFactory. |
void gst_scheduler_factory_destroy (GstSchedulerFactory *factory);
Removes the scheduler from the global list.
factory : | factory to destroy |
GstSchedulerFactory* gst_scheduler_factory_find (const gchar *name);
Search for an schedulerfactory of the given name.
name : | name of schedulerfactory to find |
Returns : | GstSchedulerFactory if found, NULL otherwise |
GstScheduler* gst_scheduler_factory_create (GstSchedulerFactory *factory, GstElement *parent);
Create a new GstScheduler instance from the
given schedulerfactory with the given parent. parent
will
have its scheduler set to the returned GstScheduler instance.
factory : | the factory used to create the instance |
parent : | the parent element of this scheduler |
Returns : | A new GstScheduler instance with a reference count of 1 .
|
GstScheduler* gst_scheduler_factory_make (const gchar *name, GstElement *parent);
Create a new GstScheduler instance from the
schedulerfactory with the given name and parent. parent
will
have its scheduler set to the returned GstScheduler instance.
If NULL
is passed as name
, the default scheduler name will
be used.
name : | the name of the factory used to create the instance |
parent : | the parent element of this scheduler |
Returns : | A new GstScheduler instance with a reference count of 1 .
|
void gst_scheduler_factory_set_default_name (const gchar *name);
Set the default schedulerfactory name.
name : | the name of the factory used as a default |
const gchar* gst_scheduler_factory_get_default_name (void);
Get the default schedulerfactory name.
Returns : | the name of the default scheduler. |
