What the licenses require

MIT, ISC, BSD and Apache-2.0 ask that the copyright notice travels with the software — this page, together with the license texts inside each package in our published bundle, satisfies that. Apache-2.0 additionally grants a patent license. FFmpeg’s core is GPL: we ship it as a separate, unmodified WebAssembly file loaded at runtime, and its complete source is available from the upstream projects linked above. Full license texts ship with each package; upstream repositories carry the canonical copies.
