The libraries linked into ffmpeg-core-rf7.wasm besides FFmpeg and LAME, pinned
exactly, so the same sources can be fetched. All are BSD-style (zlib: the zlib
licence) and do not ask for their source to be offered; their licences are in
/vendor/ffmpeg-core/LICENSE. The versions are the ones ffmpeg.wasm v0.12.10
pins (its Dockerfile), except libwebp and dav1d.
