Method Details [hide private]

get_pipeline_string(self, properties)

source code 

Method that must be implemented by subclasses to produce the gstparse string for the component's pipeline. Subclasses should not chain up; this method raises a NotImplemented error.

Returns: a new pipeline string representation.

Overrides: feedcomponent.ParseLaunchComponent.get_pipeline_string
(inherited documentation)

configure_pipeline(self, pipeline, properties)

source code 

Method that can be implemented by subclasses if they wish to interact with the pipeline after it has been created and set on the component.

This could include attaching signals and bus handlers.

Overrides: feedcomponent.ParseLaunchComponent.configure_pipeline
(inherited documentation)

do_stop(self)

source code 

BaseComponent vmethod for stopping. The component should do any cleanup it needs, but must not set the component's mood to sleeping.

Returns:
twisted.internet.defer.Deferred
Overrides: component.BaseComponent.do_stop
(inherited documentation)
