WebM
WebM is an open, royalty-free media file format designed primarily for web use, based on the Matroska container structure. It is optimized for streaming and embedding video and audio content on the web, supporting codecs like VP8, VP9, and AV1 for video and Opus and Vorbis for audio. The format is widely adopted by modern web browsers and platforms for HTML5 video playback.
Developers should learn WebM when building web applications that require efficient, high-quality video streaming without licensing fees, as it is the preferred format for HTML5 video in browsers like Chrome, Firefox, and Edge. It is particularly useful for projects involving video sharing, online education, or media-rich websites where cross-browser compatibility and performance are critical.
