The GstRTSPMediaFactory is responsible for creating or recycling GstRTSPMedia objects based on the passed URL.
The default implementation of the object can create GstRTSPMedia objects
containing a pipeline created from a launch description set with
gst_rtsp_media_factory_set_launch()
.
Media from a factory can be shared by setting the shared flag with
gst_rtsp_media_factory_set_shared()
. When a factory is shared,
gst_rtsp_media_factory_construct()
will return the same GstRTSPMedia when
the url matches.

GstRTSPMediaFactory *
gst_rtsp_media_factory_new (void
);
Create a new GstRTSPMediaFactory instance.
gchar *
gst_rtsp_media_factory_get_launch (GstRTSPMediaFactory *factory
);
Get the gst_parse_launch()
pipeline description that will be used in the
default prepare vmethod.
void gst_rtsp_media_factory_set_launch (GstRTSPMediaFactory *factory
,const gchar *launch
);
The gst_parse_launch()
line to use for constructing the pipeline in the
default prepare vmethod.
The pipeline description should return a GstBin as the toplevel element which can be accomplished by enclosing the dscription with brackets '(' ')'.
The description should return a pipeline with payloaders named pay0, pay1, etc.. Each of the payloaders will result in a stream.
GstRTSPPermissions *
gst_rtsp_media_factory_get_permissions
(GstRTSPMediaFactory *factory
);
Get the permissions object from factory
.
void gst_rtsp_media_factory_set_permissions (GstRTSPMediaFactory *factory
,GstRTSPPermissions *permissions
);
Set permissions
on factory
.
void gst_rtsp_media_factory_add_role (GstRTSPMediaFactory *factory
,const gchar *role
,const gchar *fieldname
,...
);
A convenience method to add role
with fieldname
and additional arguments to
the permissions of factory
. If factory
had no permissions, new permissions
will be created and the role will be added to it.
void gst_rtsp_media_factory_set_shared (GstRTSPMediaFactory *factory
,gboolean shared
);
Configure if media created from this factory can be shared between clients.
gboolean
gst_rtsp_media_factory_is_shared (GstRTSPMediaFactory *factory
);
Get if media created from this factory can be shared between clients.
gboolean
gst_rtsp_media_factory_is_eos_shutdown
(GstRTSPMediaFactory *factory
);
Get if media created from this factory will have an EOS event sent to the pipeline before shutdown.
void gst_rtsp_media_factory_set_eos_shutdown (GstRTSPMediaFactory *factory
,gboolean eos_shutdown
);
Configure if media created from this factory will have an EOS sent to the pipeline before shutdown.
GstRTSPLowerTrans
gst_rtsp_media_factory_get_protocols (GstRTSPMediaFactory *factory
);
Get the allowed protocols of factory
.
void gst_rtsp_media_factory_set_protocols (GstRTSPMediaFactory *factory
,GstRTSPLowerTrans protocols
);
Configure the allowed lower transport for factory
.
void gst_rtsp_media_factory_set_profiles (GstRTSPMediaFactory *factory
,GstRTSPProfile profiles
);
Configure the allowed profiles for factory
.
GstRTSPProfile
gst_rtsp_media_factory_get_profiles (GstRTSPMediaFactory *factory
);
Get the allowed profiles of factory
.
GstRTSPAddressPool *
gst_rtsp_media_factory_get_address_pool
(GstRTSPMediaFactory *factory
);
Get the GstRTSPAddressPool used as the address pool of factory
.
void gst_rtsp_media_factory_set_address_pool (GstRTSPMediaFactory *factory
,GstRTSPAddressPool *pool
);
configure pool
to be used as the address pool of factory
.
guint
gst_rtsp_media_factory_get_buffer_size
(GstRTSPMediaFactory *factory
);
Get the kernel UDP buffer size.
void gst_rtsp_media_factory_set_buffer_size (GstRTSPMediaFactory *factory
,guint size
);
Set the kernel UDP buffer size.
GstRTSPSuspendMode
gst_rtsp_media_factory_get_suspend_mode
(GstRTSPMediaFactory *factory
);
Get how media created from this factory will be suspended.
void gst_rtsp_media_factory_set_suspend_mode (GstRTSPMediaFactory *factory
,GstRTSPSuspendMode mode
);
Configure how media created from this factory will be suspended.
void gst_rtsp_media_factory_set_retransmission_time (GstRTSPMediaFactory *factory
,GstClockTime time
);
Configure the time to store for possible retransmission
GstClockTime
gst_rtsp_media_factory_get_retransmission_time
(GstRTSPMediaFactory *factory
);
Get the time that is stored for retransmission purposes
void gst_rtsp_media_factory_set_latency (GstRTSPMediaFactory *factory
,guint latency
);
Configure the latency used for receiving media
guint
gst_rtsp_media_factory_get_latency (GstRTSPMediaFactory *factory
);
Get the latency that is used for receiving media
void gst_rtsp_media_factory_set_media_gtype (GstRTSPMediaFactory *factory
,GType media_gtype
);
Configure the GType of the GstRTSPMedia subclass to create (by default, overridden construct vmethods may of course do something different)
Since: 1.6
GType
gst_rtsp_media_factory_get_media_gtype
(GstRTSPMediaFactory *factory
);
Return the GType of the GstRTSPMedia subclass this factory will create.
Since: 1.6
GstRTSPMedia * gst_rtsp_media_factory_construct (GstRTSPMediaFactory *factory
,const GstRTSPUrl *url
);
Construct the media object and create its streams. Implementations should create the needed gstreamer elements and add them to the result object. No state changes should be performed on them yet.
One or more GstRTSPStream objects should be created from the result
with gst_rtsp_media_create_stream()
.
After the media is constructed, it can be configured and then prepared
with gst_rtsp_media_prepare()
.
GstElement * gst_rtsp_media_factory_create_element (GstRTSPMediaFactory *factory
,const GstRTSPUrl *url
);
Construct and return a GstElement that is a GstBin containing the elements to use for streaming the media.
The bin should contain payloaders pay%d for each stream. The default implementation of this function returns the bin created from the launch parameter.
struct GstRTSPMediaFactory;
The definition and logic for constructing the pipeline for a media. The media can contain multiple streams like audio and video.
struct GstRTSPMediaFactoryClass { GObjectClass parent_class; gchar * (*gen_key) (GstRTSPMediaFactory *factory, const GstRTSPUrl *url); GstElement * (*create_element) (GstRTSPMediaFactory *factory, const GstRTSPUrl *url); GstRTSPMedia * (*construct) (GstRTSPMediaFactory *factory, const GstRTSPUrl *url); GstElement * (*create_pipeline) (GstRTSPMediaFactory *factory, GstRTSPMedia *media); void (*configure) (GstRTSPMediaFactory *factory, GstRTSPMedia *media); /* signals */ void (*media_constructed) (GstRTSPMediaFactory *factory, GstRTSPMedia *media); void (*media_configure) (GstRTSPMediaFactory *factory, GstRTSPMedia *media); };
The GstRTSPMediaFactory class structure.
