Unreleased FFmpeg WebAssembly LGPL-oriented candidate: corresponding source and notices
The candidate binary and conversion tools remain unpublished while license and integration review is completed.
Extract the ffmpeg.wasm source archive into a fresh directory, stripping its top-level folder.
Place the remaining 14 archives in its sources/ directory. For split archives, concatenate parts in numbered order first.
Overlay Dockerfile.lgpl and build/ffmpeg-wasm-lgpl.sh, and place source-lock-lgpl.json in that directory.
Verify each archive SHA-256 against index.json or source-lock-lgpl.json.
Run: docker buildx build --platform linux/amd64 --file Dockerfile.lgpl --target exportor --output type=local,dest=./output .
The pinned Docker base image is specified by digest in Dockerfile.lgpl.
The local isolated rebuild matched the three candidate artifact SHA-256 hashes in index.json.
CHANGES.txt identifies build overlays and confirms that the FFmpeg source archive is unmodified.
site-adapter/ contains the site's FFmpeg browser loader and argument builder source, with permissions for modification for your own use and reverse engineering for debugging those modifications.
The unmodified upstream ffmpeg.wasm archive can contain optional GPL build scripts; they are not invoked by this recipe.
This source package alone does not establish that the LGPL obligations for a statically linked WebAssembly distribution have been satisfied.
