What the Playback Stack Includes

Codecs decode compressed streams, and containers such as MKV or MP4 need splitters to expose every track. K-Lite Codec Pack installs a balanced, Windows‑ready stack so files are recognized and played correctly.

Instead of forcing a new player, it upgrades the Windows pipeline directly. The result is smoother playback, reliable audio tracks, and subtitles that stay synchronized.
