Licensing#

The wrapper, scripts, and documentation in this repository are MIT licensed.

Generated FFmpeg assets in dist/ are copied from FFmpeg and are LGPL-2.1-or-later. The build does not pass --enable-gpl or --enable-nonfree.

Practical Split#

Keep these pieces conceptually separate:

• MIT wrapper source, scripts, docs, and TypeScript declarations.
• LGPL FFmpeg wasm, JavaScript loader output, worker output, and copied license files.

Current Build Choices#

The build includes LAME for MP3 output and FFmpeg's native MPEG-4 encoder for lightweight MP4 downscales. FFmpeg stays configured without GPL or nonfree flags.

Distribution#

When packaging this under another scope, keep FFmpeg license files next to the generated assets and make it clear which files are LGPL-covered generated FFmpeg output.
