GstTracer

Tracing modules will subclass GstTracer and register through gst_tracer_register. Modules can attach to various hook-types - see gst_tracing_register_hook. When invoked they receive hook specific contextual data, which they must not modify.

Class Methods

gst_tracer_class_set_use_structure_params 

gst_tracer_class_set_use_structure_params (GstTracerClass * tracer_class,
                                           gboolean use_structure_params)

Sets whether the tracer should use structure parameters for configuration. This function configures how parameters should be passed when instantiating the tracer.

This is typically called in the tracer's class initialization function to indicate its parameter handling preference.

Parameters:

tracer_class –
No description available
use_structure_params –

TRUE to use structure parameters, FALSE otherwise

Since : 1.26

Gst.TracerClass.prototype.set_use_structure_params 

function Gst.TracerClass.prototype.set_use_structure_params(tracer_class: Gst.TracerClass, use_structure_params: Number): {
    // javascript wrapper for 'gst_tracer_class_set_use_structure_params'
}

Sets whether the tracer should use structure parameters for configuration. This function configures how parameters should be passed when instantiating the tracer.

This is typically called in the tracer's class initialization function to indicate its parameter handling preference.

Parameters:

tracer_class (Gst.TracerClass) –
No description available
use_structure_params (Number) –

true to use structure parameters, false otherwise

Since : 1.26

gst_tracer_class_uses_structure_params 

gboolean
gst_tracer_class_uses_structure_params (GstTracerClass * tracer_class)

If set, the tracer subsystem will consider parameters passed to the GST_TRACERS environment variable as a GstStructure and use its fields as properties to instanciate the tracer.

Parameters:

tracer_class –
No description available
Returns –

TRUE if the tracer uses structure parameters, FALSE otherwise

Since : 1.26

Gst.TracerClass.prototype.uses_structure_params 

function Gst.TracerClass.prototype.uses_structure_params(tracer_class: Gst.TracerClass): {
    // javascript wrapper for 'gst_tracer_class_uses_structure_params'
}

If set, the tracer subsystem will consider parameters passed to the GST_TRACERS environment variable as a Gst.Structure and use its fields as properties to instanciate the tracer.

Parameters:

tracer_class (Gst.TracerClass) –
No description available
Returns (Number) –

true if the tracer uses structure parameters, false otherwise

Since : 1.26

Functions

gst_tracer_register 

gboolean
gst_tracer_register (GstPlugin * plugin,
                     const gchar * name,
                     GType type)

Create a new tracer-factory capable of instantiating objects of the type and add the factory to plugin.

Parameters:

plugin ( [allow-none]) –

A GstPlugin, or NULL for a static typefind function

name –

The name for registering

type –

GType of tracer to register

Returns –

TRUE, if the registering succeeded, FALSE on error

Gst.Tracer.prototype.register 

function Gst.Tracer.prototype.register(plugin: Gst.Plugin, name: String, type: GObject.Type): {
    // javascript wrapper for 'gst_tracer_register'
}

Create a new tracer-factory capable of instantiating objects of the type and add the factory to plugin.

Parameters:

plugin (Gst.Plugin) –

A Gst.Plugin, or null for a static typefind function

name (String) –

The name for registering

type (GObject.Type) –

GType of tracer to register

Returns (Number) –

true, if the registering succeeded, false on error

Gst.Tracer.register 

def Gst.Tracer.register (plugin, name, type):
    #python wrapper for 'gst_tracer_register'

Create a new tracer-factory capable of instantiating objects of the type and add the factory to plugin.

Parameters:

plugin (Gst.Plugin) –

A Gst.Plugin, or None for a static typefind function

name (str) –

The name for registering

type (GObject.Type) –

GType of tracer to register

Returns (bool) –

True, if the registering succeeded, False on error
