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.

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

Module describing context passed to the Membrane.Bin callbacks.

Struct describing current pad state.

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

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

Struct describing child entry of a parent.

A child notification is a message sent from Membrane.Element or Membrane.Bin to a parent via action t:Membrane.Element.Action.notify_parent or t:Membrane.Bin.Action.notify_parent returned from any callback.

A module with functionalities that allow to represent a topology of a pipeline/bin.

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.

A list consisting of following pipeline/bin/element names down the assembled pipeline.

Membrane Filter, that can be used to create a child that will be used to debug data flowing thouth pipeline.

Membrane Sink, that can be used to create a child that will be used to debug data flowing thouth pipeline.

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.

Describes context passed to the Membrane Element callbacks.

Struct describing current pad state.

Module defining behaviour for sink, filter and endpoint elements.

Module defining behaviour for source and filter elements.

Module defining behaviour for endpoints - elements consuming and producing data.

Represents a communication event, capable of flowing both downstream and upstream.

Generic discontinuity event.

Generic underrun event.

Protocol that allows to configure behaviour of Membrane.Events.

Module defining behaviour for filters - elements processing data.

An element allowing to aggregate many filters within one Elixir process.

Generic event for requesting a key frame.

Wrapper around the Elixir logger. Adds Membrane prefixes and handles verbose logging.

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

A parent notification is a message sent from Membrane.Parent or Membrane.Bin to a child via action t:Membrane.Pipeline.Action.notify_parent or t:Membrane.Bin.Action.notify_child returned from any callback.

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.

A behaviour module for implementing pipelines.

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

Module describing context passed to the Membrane.Pipeline callbacks.

Playback defines whether media is processed within a pipeline (:playing) or not (:stopped).

An abstract module aggregating all the messages that can be sent by the RCPipeline.

Message sent when some element of the pipeline receives the start of stream event on some pad.

Message sent when the some element of the pipeline receives a notification.

Message sent when the pipeline starts playing

Message sent when some element of the pipeline receives the start of stream event on some pad.

Message sent when the pipeline gracefully terminates.

Remote controlled pipeline - a basic Membrane.Pipeline implementation that can be remotely controlled from an external process.

Format describing an unparsed data stream. It should be used whenever outputting or accepting an unknown stream (not to be confused with any stream, which can have well-specified format either), or a stream whose format can't/shouldn't be created at that stage.

Utility for handling resources that must be cleaned up after use.

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.

Defines the capabilities of a pad within the Membrane framework.

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

Defines basic telemetry event types used by Membrane's Core.

This module contains a set of assertion functions and macros.

Testing Element for supplying data based on generator function or payloads passed through options. It is very similar to Membrane.Testing.Source but is has dynamic pad instead of static.

Empty event that can be used in tests

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

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

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

Module containing functions needed to perform handling of time.

A supervisor responsible for managing utility processes under the pipeline's supervision tree.
