ffmpeg-core 4.1

Core runtime for typed-ffmpeg (DAG, compilation, IR layer)

ffmpeg-core

Core runtime for typed-ffmpeg multi-version packages.

Overview

ffmpeg-core contains the hand-written runtime code that is shared across all FFmpeg version bindings (v5, v6, v7, v8). This package is automatically installed as a dependency when you install any typed-ffmpeg-vX package.

What's Inside

• DAG Layer (ffmpeg_core.dag): Filter graph representation and manipulation
• Compile Layer (ffmpeg_core.compile): FFmpeg command-line generation
• IR Layer (ffmpeg_core.ir): Intermediate representation for multi-backend support
• Common Utilities (ffmpeg_core.common): Serialization, caching, schemas

Installation

This package is installed automatically:

# Installing any version package will install ffmpeg-core
pip install typed-ffmpeg-v8

# You can also install it directly (advanced)
pip install ffmpeg-core

Usage

Note: Most users don't need to import from ffmpeg-core directly. Use the version-specific packages (typed-ffmpeg, typed-ffmpeg-v6, etc.) instead.

For advanced use cases:

from ffmpeg_core.dag import FilterNode, Stream
from ffmpeg_core.compile import compile_as_list

# Clone monorepo
