# pyobjc-framework-CoreMedia — Wrappers for the framework CoreMedia on macOS

License: permissive · Maintenance: active · Downloads: 743.9K/mo

## What it is and what it does

This package wraps Apple's CoreMedia framework for use in Python, allowing developers to interact with macOS media APIs from Python code. CoreMedia is a low-level framework for handling audio and video data, timing, and format information on macOS. The package depends on pyobjc-core and pyobjc-framework-Cocoa to bridge between Python and Objective-C.

The wrappers expose CoreMedia's C and Objective-C interfaces directly to Python without additional documentation beyond Apple's own framework docs and PyObjC's general translation guidance. It is intended for developers building macOS applications that need direct access to media handling at the framework level, rather than higher-level audio or video libraries.

Use it for:

- Building macOS applications that need to work with raw audio or video samples and timing information
- Integrating Python media processing code with native macOS media pipelines
- Accessing CoreMedia's format and timing utilities for audio/video metadata handling on macOS

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides Python bindings to macOS's CoreMedia framework, enabling access to media-related APIs for audio and video processing on macOS.

Yes, if you are developing on macOS and need direct access to CoreMedia APIs from Python. The package is actively maintained, has no known vulnerabilities, and carries a permissive license. Install friction is moderate due to platform specificity and dependency chain, but unavoidable for this use case. Not applicable on non-macOS systems.

## Install

pip install pyobjc-framework-coremedia
uv add pyobjc-framework-coremedia
poetry add pyobjc-framework-coremedia

## Installing pyobjc-framework-CoreMedia

Before you install: Medium install friction: platform-specific wheels for macOS only (Python 3.10–3.15, including free-threading variants). Requires pyobjc-core and pyobjc-framework-Cocoa as runtime dependencies. Active maintenance with a release 3 days old.

License in practice: MIT license permits commercial and private use with minimal restrictions; suitable for most projects.

Quickstart:

pip install pyobjc-framework-coremedia

import CoreMedia
# Access CoreMedia APIs through the framework binding

macOS only; requires Python 3.10 or later and a macOS system with the CoreMedia framework available

Verify before relying:

- Whether CoreMedia APIs are fully wrapped or if some lower-level functionality requires direct Objective-C code
- Performance characteristics when bridging between Python and CoreMedia for real-time media operations
