membraneframework/membrane_core

This system is the core runtime and framework for building media processing pipelines in Elixir. It provides a structured API for defining elements, bins, and pipelines, managing their lifecycles, and handling data flow and events. The codebase includes utilities for benchmarking performance, generating component templates, and running comprehensive integration and unit tests to ensure stability.

How it got here

2016–2018 · core architecture and testing

This period focused on establishing the foundational architecture of the Membrane framework, introducing core abstractions for elements, pipelines, and data flow. The work included refactoring the internal component structure into a modular, namespaced design and implementing comprehensive test coverage for the new core components and testing utilities.

2019–2020 · Core architecture refactoring and test expansion

This period focused on refactoring the Membrane core into dedicated modules for bins, children, and pipelines to improve code organization and maintainability. Concurrently, extensive unit and integration tests were added to validate the new structure and ensure robust handling of lifecycles, pads, and crash groups.

15 changes

2021–2023 · Core infrastructure and test coverage

This period focused on strengthening the Membrane Core framework by introducing distributed atomic demand tracking, crash group management, and debug components for pipeline inspection. Significant effort was also dedicated to expanding test coverage for the FilterAggregator, parent structure parsing, and format acceptance logic, alongside establishing automated performance regression detection.

14 changes

2024–2026 · Developer tooling and documentation expansion

This period focused on enhancing the developer experience by introducing manual flow control with timestamp-based demand and telemetry. The team also expanded the project's scaffolding capabilities with new Mix tasks and component templates, while adding interactive demos and tutorials to the documentation.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 6 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit d5fa06b929 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
