Richard R 9b9206f50d refactor(audiobooks): migrate audiobook pipeline to object storage
This commit restructures the audiobook generation and serving layer to rely exclusively on S3-compatible blob storage, removing the dependency on local filesystem paths.

- Bundle `ffmpeg` and `ffprobe` binaries via npm to ensure portability across environments.
- Update API routes to stream audio directly from blob storage instead of local disk.
- Remove legacy migration endpoints and filesystem-based indexing logic.
- Add startup scripts to facilitate the transition from local to remote storage.

BREAKING CHANGE: Audiobook functionality is now strictly dependent on S3 configuration. The previous filesystem-based storage method has been removed.

Orpheus-FastAPI

Use Orpheus-FastAPI as an OpenAI-compatible TTS backend for OpenReader.

Upstream project

OpenReader setup

  1. Start your Orpheus-FastAPI server.
  2. In OpenReader settings, choose provider Custom OpenAI-Like and model Orpheus.
  3. Set OpenReader API_BASE to your Orpheus base URL (typically ending with /v1).
  4. Set API_KEY if your Orpheus deployment requires one.
  5. Choose voice.

Notes

  • API_BASE is needed here because Orpheus is configured through the custom provider path.
  • OpenReader expects OpenAI-compatible audio endpoints.
  • For variable details, see Environment Variables.
