# Adjustments BD-J Authoring Notes

This project starts from the BD-J Linux SDK template disc metadata. The Xlet
entry point is intentionally `org.homebrew.MyXlet` because
`vendor/bdj-sdk/resources/AVCHD/BDMV/BDJO/00000.bdjo` launches that class.

The build does three separate jobs:

1. `ffmpeg` generates a temporary 720p23.976 MPEG-2 elementary stream and AC-3
   audio.
2. `tsMuxeR` authors those streams into Blu-ray playlist, clipinfo, and M2TS
   files.
3. The BD-J SDK signs `BDMV/JAR/00000.jar` and packages the final UDF 2.50 ISO.

Useful commands:

```sh
make bootstrap
make
make inspect
make run
```

Hidden-menu scaffold:

- The visible menu has the main feature, two bonus-feature placeholders, and
  settings.
- Pressing `6`, `6`, `6` opens the hidden placeholder menu.
- The generated main feature is playlist `00000`.

For real assets later, keep the `00000` numbering until the BDJO/index metadata
is regenerated or replaced with an authoring tool that owns those files too.
