## [Unreleased]

## media-info-wdx 0.2.0 — 2026-07-04

### Added
- **media-info-wdx:** **Matroska / WebM support** (`.mkv`, `.webm`). macOS system
frameworks can't open these EBML containers, so a self-contained EBML parser
reads dimensions (aspect-correct display size), duration, frame rate, video/audio
codecs, sample rate, and channels directly from the file — mirroring the existing
AVI RIFF reader, with no dependency and no network. The parser *seeks* over the
Segment's children (reading only element headers plus the small Info/Tracks
bodies, skipping past large SeekHead/Cues/Attachments), so it works in a few KB
regardless of file size and never misses a file whose `Tracks` sits past a fixed
byte window. Duration is bounds-checked against corrupt/hostile input. Both
extensions are added to the category table and the DetectString, and routed to
the fast (non-deferred) parse path.
