What is a OGG file?

Ogg is a free, patent‑unencumbered container maintained by the Xiph.Org Foundation. It most commonly encapsulates Vorbis or Opus audio but also supports Theora or Dirac video and embeds tags via VorbisComment. Ogg 1.0 shipped in 2000 following the ‘Danube’ code‑freeze after MP3 licensing scares. Firefox added native playback in 2008, spurring podcast adoption. Although WebM supplanted Ogg Theora for video, .ogg audio thrives in game engines and Fedora distributions.

What is a MKV file?

Matroska Video (MKV) is a flexible open container that can accommodate virtually any codec, multiple subtitle tracks, and chapter points. It is built on EBML (Extensible Binary Meta Language), a binary cousin of XML, allowing unlimited, self‑describing elements. The project began in 2002 after developer Steve Lhomme forked the failed MCF container. With the explosion of H.264 ‘fansubs’, MKV became the default wrapper for anime communities, bundling soft‑subs and styled karaoke effects. In 2013 Matroska was standardised within the IETF as the basis for WebM, cementing its longevity.

Firefox, Chrome, and every Linux desktop decode .ogg natively. On Windows, install Opus/Vorbis DirectShow filters or use VLC. Sound editors like Audacity open Ogg while preserving loop metadata for game assets.

How to open a MKV file?

VLC, MPV, and Kodi handle MKV flawlessly on every OS. Editing suites such as DaVinci Resolve import common codecs like H.264 or ProRes within MKV, but for delivery you may still export MP4. MKVToolNix lets you split, merge, and tag tracks without re‑encoding.
