AetherEngine is distributed under LGPL-3.0 with its App Store / DRM Exception. The AetherEngine Swift package is compiled into the application; its FFmpeg and related runtime frameworks remain dynamically linked. Relative to the upstream revision above, Video +:

- routes AirPlay sessions that have an HLS master through the reduced master playlist so native WebVTT subtitle renditions are retained, and re-applies the active native subtitle after the AirPlay reload;
- lets callers skip ISO/UDF disc-image probing for custom readers already known to represent ordinary media, including reopen, subtitle-reader, and frame-extractor paths; and
- exposes selected decoder and demuxer errors as localized, sendable public errors for the host application's user-facing diagnostics.

The exact modified and pristine AetherEngine source, a generated patch, this notice, and checksums are published at https://apprevenge.com/cloudvideoplayer/open-source/. Video + does not modify LibDovi or the FFmpegBuild frameworks. FFmpegBuild's documented libzvbi source exclusions and LGPL stubs are part of the upstream FFmpegBuild 2.1.0 build.
