Method Details

[hide private]

init(self)

source code

A subclass should do as little as possible in its init method. In particular, it should not try to access resources.

Failures during init are marshalled back to the manager through the worker's remote_create method, since there is no component state proxied to the manager yet at the time of init.

Overrides: component.BaseComponent.init: (inherited documentation)

set_master_clock(self, ip, port, base_time)

source code

Overrides: feedcomponent010.FeedComponent.set_master_clock

provide_master_clock(self, port)

source code

Tell the component to provide a master clock on the given port.

Returns:: a deferred firing a (ip, port, base_time) triple.
Overrides: feedcomponent010.FeedComponent.provide_master_clock: (inherited documentation)

get_master_clock(self)

source code

Return the connection details for the network clock provided by this component, if any.

Overrides: feedcomponent010.FeedComponent.get_master_clock: (inherited documentation)

create_pipeline(self)

source code

Subclasses have to implement this method.

Returns: gst.Pipeline
Overrides: feedcomponent010.FeedComponent.create_pipeline: (inherited documentation)

do_check(self)

source code

Subclasses can implement me to run any checks before the component performs setup.

Messages can be added to the component state's 'messages' list key. Any error messages added will trigger the component going to sad, with flumotion.common.errors.ComponentSetupError being raised before getting to setup stage; do_setup() will not be called.

In the event of a fatal problem that can't be expressed through an error message, this method should raise an exception or return a failure.

It is not necessary to chain up in this function. The return value may be a deferred.

Overrides: component.BaseComponent.do_check: (inherited documentation)

do_setup(self)

source code

Sets up component.

Invokes the create_pipeline and set_pipeline vmethods, which subclasses can provide.

Overrides: component.BaseComponent.do_setup: (inherited documentation)
