Video processor licences and source references
Audio Studio uses a browser video processor derived from @ffmpeg/ffmpeg 0.12.15 and the single-thread @ffmpeg/core 0.12.10. The wrapper is MIT-licensed; the core package is declared GPL-2.0-or-later. Individual component and source-file notices remain applicable.
Status: reference snapshots; binary correspondence not confirmed.
The archives below contain repository snapshots of candidate source inputs resolved from the matching upstream build recipe. They are pinned and hashed so that these exact downloads can be identified. This does not establish that they are the complete corresponding source for the npm core binary currently distributed here, or that the published binary has been reproduced.
这里提供的是已固定提交和校验值的候选来源源码快照。现有 npm 引擎二进制与这些源码的精确对应关系尚未确认，尚未完成自建和可复现构建验证。下载资料已提供，不代表公开分发所需的全部对应源码事项已经完成。

Pinning a moving branch today does not identify the branch revision used when a binary was published. The original recipe uses moving x264 and LAME branches and a Docker image tag without a fixed digest. Exact historical revisions, toolchain/runtime scope and reproduction remain unresolved. Read BUILDING.txt before attempting a build.
