WebM Project: An Overview

The WebM Project is an open-source multimedia container format designed for the web. It was developed to facilitate high-quality video and audio streaming over the internet, making it a popular choice for web developers and content creators alike.

History

The WebM Project was initiated by Google in 2010 as a response to the increasing need for a royalty-free format suitable for web use. The format is based on the Matroska container, and it primarily uses the VP8 and VP9 video codecs, alongside the Vorbis and Opus audio codecs. Initially, its main goal was to provide an alternative to proprietary formats like H.264 and AAC, ensuring that web developers could embed video content without the burdens of licensing fees.

In 2015, the WebM Project introduced VP9, which offered improved compression efficiency and quality over its predecessor, VP8. As web standards evolved, WebM has gained widespread support across browsers and platforms, solidifying its position as a go-to format for HTML5 video.
