Membrane Core v0.5.0 API Reference

Modules

Bins, similarly to pipelines, are containers for elements. However, at the same time, they can be placed and linked within pipelines. Although bin is a separate Membrane entity, it can be perceived as a pipeline within an element. Bins can also be nested within one another.

Structure representing a context that is passed to the bin when when a new dynamic pad instance added is created

Structure representing a context that is passed to the bin when a dynamic pad is removed

Structure representing a single chunk of data that flows between elements.

Specifies API for metrics that analyze data in terms of a given unit

Implementation of Membrane.Buffer.Metric for the :bytes unit

Implementation of Membrane.Buffer.Metric for the :buffers unit

Parent module for all contexts passed to callbacks.

Describes capabilities of some pad.

Module that allows to specify valid caps and verify that they match specification.

Module that keeps track of types used by both elements and bins

Clock is a Membrane utility that allows elements to measure time according to a particular clock, which can be e.g. a soundcard hardware clock.

Buffer that is attached to the :input pad when working in a :pull mode.

Module containing types and functions for operating on elements.

This module contains type specifications of actions that can be returned from element callbacks.

Module defining behaviour common to all elements.

This module has been deprecated in favour of Membrane.Filter.

This module has been deprecated in favour of Membrane.Sink.

This module has been deprecated in favour of Membrane.Source.

Structure representing a context that is passed to the element when receiving information about new caps for given pad.

Structure representing a context that is passed to the element when processing incoming demand.

Structure representing a context that is passed to the element when handling event.

Structure representing a context that is passed to the callback when element receives unrecognized message.

Structure representing a context that is passed to the element when a new dynamic pad instance is created

Structure representing a context that is passed to the element when a dynamic pad is removed

Structure representing a context that is passed to the callback of the element when it changes playback state

Structure representing a context that is passed to the element when new buffer arrives.

Structure representing a context that is passed to the element when handling start and end of stream events.

Structure representing a context that is passed to the callback when element handles timer tick.

Structure representing a context that is passed to the element when new buffer arrives to the sink.

Module defining behaviour for sink and filter elements.

Module defining behaviour for source and filter elements.

Event is an entity that can be sent between elements.

Generic discontinuity event.

Generic End of Stream event.

Generic Start of Stream event.

Generic underrun event.

Protocol that allows to configure behaviour of Membrane.Events.

Module defining behaviour for filters - elements processing data.

Mixin for logging using simple functions such as info/1, debug/1 in other modules.

Module containing functions spawning, shutting down, and handling messages sent to logger.

This is a base module used by all logger implementations.

Defines a router that dispatches logs to instances of Membrane.Log.Logger.Base

Module responsible for supervising router_level loggers. It is also responsible for receiving and routing log messages to appropriate loggers.

A notification is a message sent from Membrane.Element to a parent via action Membrane.Element.Action.notify_t/0 returned from any callback.

Pads are units defined by elements and bins, allowing them to be linked with their siblings. This module consists of pads typespecs and utils.

Struct describing current pad state.

Module that manages a common part between pipelines and bins.

Common types' definitions for bin and pipeline.

Structure representing topology of a pipeline/bin.

This protocol describes actions common to all payload types.

Behaviour that should be implemented by every module that has Membrane.Payload protocol implementation.

Membrane.Payload.Behaviour implementation for binary payload. Complements Membrane.Payload protocol implementation.

Module containing functions for constructing and supervising pipelines.

Playback states describe the state of an element or a pipeline. There are following playback states

Module defining behaviour for sinks - elements consuming data.

Module that should be used in sources - elements producing data. Declares appropriate behaviours implementation and provides default callbacks implementation.

Sync allows to synchronize multiple processes, so that they could perform their jobs at the same time.

This module contains a set of assertion functions and macros.

Empty event that can be used in tests

This Pipeline was created to reduce testing boilerplate and ease communication with its elements. It also provides a utility for informing testing process about playback state changes and received notifications.

Structure representing options passed to testing pipeline.

Structure representing state.

Sink Element that notifies the pipeline about buffers and events it receives.

Testing Element for supplying data based on generator function passed through options.

Module containing functions needed to perform handling of time.
