WebM
WebM is an open, royalty-free media file format designed for web streaming, primarily supporting video and audio content. It is based on the Matroska container format and uses VP8, VP9, or AV1 for video compression and Opus or Vorbis for audio compression. WebM is widely used for HTML5 video playback on websites and in applications due to its efficient compression and broad browser support.
Developers should learn WebM for implementing video streaming in web applications, as it offers high-quality compression with smaller file sizes compared to alternatives like MP4, reducing bandwidth costs and improving load times. It is essential for projects requiring cross-browser compatibility without licensing fees, such as online video platforms, educational content, or live streaming services. Use cases include embedding videos in HTML5, building video players, or optimizing media delivery for mobile devices.
