This page lists third-party software distributed with Filu that calls for a visible notice or source-code access.

What this page covers

Filu uses many third-party packages. This page only lists distributed components whose license terms call for a visible notice, source-code access, or a source download.

FFmpeg browser media core

Filu ships the @ffmpeg/core browser package for selected media conversions. This package provides the FFmpeg WebAssembly core loaded by the browser for those conversions.

  • Software: @ffmpeg/core@0.12.10, FFmpeg WebAssembly single-thread core.
  • License: GPL-2.0-or-later as published in the @ffmpeg/core npm package metadata.
  • Source: review the @ffmpeg/core package and upstream ffmpeg.wasm project for package source and build materials.
  • Codec notice: M4A and MPG to MP4 output use FFmpeg's native AAC encoder and libx264 H.264/AVC encoder. AAC and H.264/AVC may carry patent or platform-distribution considerations separate from open-source license compliance.
