BDInfo

The utility reads Blu‑ray movie discs and extracts detailed technical data about the video and audio streams they contain. It reports attributes such as disc size, playlist structure, video codec, resolution, frame rate, audio codec, channel layout, and language tracks. The information is presented in a readable format that can be used for cataloguing or preparing further processing steps.

It is aimed at users who need to audit or document the contents of Blu‑ray media, including home‑theater enthusiasts, archivists, and developers building workflows that involve ripping or converting Blu‑ray discs. The tool runs on macOS and is distributed as a stable, portable application.

What distinguishes it is its focus on comprehensive specification collection rather than actual ripping, providing a quick way to view all relevant codec and track details without launching a full media player or conversion suite.
