lzo-decompress

Use LZO for decompression on Node.js

Introduction

lzo-decompress is an N-API wrapper around the LZO implementation of FFMpeg's libavutil library. It uses version 3 of N-API which is only available on Node v10 and higher. v0.1.2 works in Electron v3, while v1.0.0 works in Electron v4 and higher.

This software uses code of FFmpeg licensed under the LGPLv3 and its source can be downloaded here.

Usage

const lzo = require('lzo-decompress');

lzo.decompress(input, length);

Building from source

• yarn prebuild
• yarn prebuild-ia32 (for 32-bit versions)

On macOS, you may need to do brew install ffmpeg first.

Updating on Yarn/NPM

The following steps will update the module on Yarn/NPM:

• yarn version
• git push && git push --tags
• Wait for Travis to finish.
• Download the releases from Github: prebuildify-ci download
• npm publish

Note that you need to yarn global add prebuildify-ci to get the prebuilds.

Building ffmpeg

If for some reason you need to rebuild the shared libraries, use the ffmpeg-windows-build-helpers script to build LGPL-licensed 32-bit and 64-bit cross-compiled shared libraries as follows:

./cross_compile_ffmpeg.sh --enable-gpl=n --build-ffmpeg-shared=y --compiler-flavors=multi
