Matroska
Matroska is an open, royalty-free multimedia container format that can hold an unlimited number of video, audio, picture, or subtitle tracks in one file. It is widely used for storing video content, such as movies and TV shows, and is the basis for the popular WebM format. The format is known for its flexibility, extensibility, and support for modern features like chapters, menus, and metadata.
Developers should learn Matroska when working with multimedia applications, video processing, or streaming services, as it is the standard container for high-quality video distribution and archival. It is essential for creating or manipulating video files in tools like FFmpeg, VLC, or media servers, and is commonly used in scenarios like video editing, transcoding, and web video delivery (e.g., via WebM).
