pyobjc-framework-CoreMediaIO

What it is and what it does

This package wraps Apple's CoreMediaIO framework for use in Python, allowing developers to interact with macOS media input and output devices programmatically. It is built on PyObjC, which translates between Python and Objective-C, and depends on pyobjc-core and pyobjc-framework-Cocoa to function.

The wrapper does not include its own documentation; users must consult Apple's CoreMediaIO documentation alongside PyObjC's general translation guides. It is intended for developers building macOS applications that need direct control over audio and video capture devices or media I/O routing.

Use it for:

• Build macOS applications that enumerate and control audio/video input devices programmatically.
• Create custom media capture pipelines that interact directly with CoreMediaIO device abstractions.
• Develop macOS system utilities that manage media device routing or configuration.
• Integrate CoreMediaIO functionality into Python-based audio/video processing workflows on macOS.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Provides Python bindings to Apple's CoreMediaIO framework on macOS, enabling programmatic control of media input/output devices and audio/video capture.

Yes, if you are developing on macOS and need direct access to CoreMediaIO for media device control. The package is actively maintained, carries no known vulnerabilities, and uses a permissive license. Install friction is moderate due to platform specificity and compiled dependencies, but this is unavoidable for framework bindings. Not applicable on non-macOS systems.

Install

pyobjc-framework-coremediaio on PyPI

pip install pyobjc-framework-coremediaio

uv add pyobjc-framework-coremediaio

poetry add pyobjc-framework-coremediaio

Installing pyobjc-framework-CoreMediaIO

Before you install

Medium install friction: platform-specific wheels for macOS only (versions 10.9 to 10.15 depending on Python version), requires pyobjc-core and pyobjc-framework-Cocoa. Actively maintained with a release 3 days old and recent commits.

License in practice

MIT license permits commercial and private use with minimal restrictions, making it suitable for most projects.

Quickstart

pip install pyobjc-framework-coremediaio

import CoreMediaIO
# Access CoreMediaIO framework objects and methods via PyObjC bindings

macOS only; requires Python 3.10 or later; requires a compatible macOS version (10.9 minimum, 10.15 for Python 3.14+).

Verify before relying

• Specific CoreMediaIO API coverage and completeness compared to native framework
• Performance characteristics for real-time media I/O operations
• Known limitations or gaps in the wrapper implementation
