Legacy exact reproduction wheel for old codec assets

codec-video-prep-legacy-exact

Legacy exact reproduction wheel for old codec assets from the Compressed Video Reader project.

Overview

This package provides a legacy, exact reproduction environment for generating codec assets using the original/old codebase from the Compressed Video Reader project. It ensures bit-exact compatibility with previously generated codec patch datasets.

Key Features

• Exact Reproduction: Produces identical output to the original codec asset generation pipeline
• Multi-Python Support: Works with Python 3.10, 3.11, and 3.12
• Legacy Backend: Uses ffmpeg_native decode backend (not the newer cv_pixel path)
• Pre-built Extensions: Includes compiled C++ extensions for fast video processing

Installation

pip install codec-video-prep-legacy-exact

Usage

After installation, use the CLI command:

# Process a single video
codec-video-prep-legacy-exact --input video.mp4 --output ./output

# See all options
codec-video-prep-legacy-exact --help

The CLI entrypoint calls tool.pipeline.process_video_bitcost_readiness:main.

Important Constraints

This legacy package enforces the following settings for exact reproduction:

• decode_backend: ffmpeg_native (required)
• avoid_keyframes: False (required)
• Does NOT use the newer cv_pixel code path

Package Contents

• codec_selector/: Codec selection and pipeline framework
• tool/: Video processing tools and pipelines
• cv_reader/: Video reader with C++ extensions (api + frame_decode)
• cv_reader_fast/: Fast video reader with C++ extensions

System Requirements
