Settings — Media

The Media tab shows the status of Nebulae's embedded optical-disc cinema engine — which media player is detected, what disc formats it supports, and whether BD-J Java menus are available.

Settings Media tab

Optical Disc Cinema & Media Player

Playback runs inside Nebulae using VLC's embedded engine. It supports:

  • DVD menus (VIDEO_TS folder, .iso image)
  • Blu-ray menus (BDMV folder, .iso image)
  • Automatic high-quality deinterlacing

Video renders in Nebulae's own player window with its own transport controls.

Re-probe Player

Click Re-probe Player to force Nebulae to re-scan for a compatible VLC installation. This is useful after installing VLC while Nebulae is already running.

Detected Disc Player Card

Indicator Description
Detected Disc Player (badge) Embedded (In-App) — VLC was found and is linked. VLC Not Found — no compatible VLC binary detected.
Player Name The exact product name of the detected player (e.g., VLC media player).
Binary Location The absolute path to the VLC binary on disk.

Tip

If VLC Not Found appears, install VLC media player from the official site and click Re-probe Player. On macOS, place VLC in /Applications. On Windows, use the standard installer.

Disc Format & Menu Capabilities

Capability Description
DVD Menus (dvdnav) SUPPORTED — VLC was compiled with dvdnav and can render interactive DVD main and chapter menus. UNAVAILABLE — disc titles can still play but menus are not available.
Blu-ray Menus (libbluray) SUPPORTED — VLC was compiled with libbluray and can render BDMV title/playlist navigation. UNAVAILABLE — titles may still play using fallback playlist mode.

BD-J Interactive Java Menus

Modern Blu-ray and UHD discs use BD-J (Blu-ray Disc Java) for animated, interactive menus.

Status Meaning
JVM ACTIVE A Java Runtime Environment was detected at JAVA_HOME. Full interactive BD-J menus and extras are enabled.
LIMITED (NO JVM) No JRE found. Standard playlist and title navigation works cleanly; advanced animated BD-J menus are limited or unavailable.

Note

To enable BD-J menus, install a Java Runtime Environment (JDK or JRE 11+) and ensure JAVA_HOME is set correctly in your environment. After installing, re-probe the player.

AACS & Commercial Disc Limitation

Caution

Nebulae supports unprotected raw optical disc structures and community home rips only. Commercial pressed discs with active AACS or BD+ encryption require prior decryption by a separate tool. Nebulae contains zero DRM circumvention tools or decryption keys.
