WebM

WebM is a free and open multimedia container format designed to provide a royalty-free alternative to the H.264 and MPEG-4 formats. Developed by Google, Mozilla Foundation, and Opera Software, WebM is primarily intended for use with HTML5 video and audio elements, as seen in YouTube, Vimeo, and Internet Archive. The format has gained support from major technology companies, including Microsoft, Amazon, and Facebook. WebM is also used by Wikipedia, Wikimedia Commons, and other Wikimedia Foundation projects.

Introduction

The introduction of WebM was announced at the Google I/O conference in 2010, with the goal of creating a free and open standard for web video. This effort was supported by Bing, Yahoo!, and other major search engines, as well as Adobe Systems, AMD, and ARM Holdings. WebM is based on the Matroska container format, which was originally developed by Lasse Kärkkäinen and Erik Fish. The format uses the VP8 video codec, which was acquired by Google from On2 Technologies, and the Vorbis audio codec, which was developed by Xiph.Org Foundation. WebM has also been adopted by Netflix, Twitch.tv, and other online video platforms.

History

The development of WebM began in 2009, when Google acquired On2 Technologies and its VP8 video codec. The VP8 codec was then open-sourced and combined with the Vorbis audio codec to create the WebM format. The first version of WebM was released in 2010, with support from Mozilla Firefox, Opera, and Chromium. Since then, WebM has undergone several updates, including the addition of support for the VP9 video codec, which was developed by Google and Xiph.Org Foundation. WebM has also been adopted by Ubuntu, Debian, and other Linux distributions, as well as Android and iOS mobile operating systems.

Format

The WebM format is based on the Matroska container format, which provides a flexible and extensible framework for storing multimedia data. WebM files typically have a `.webm` extension and can contain video, audio, and metadata tracks. The format supports a wide range of codecs, including VP8, VP9, and Vorbis, as well as Opus and PCM. WebM files can be played back using a variety of software players, including VLC media player, MPlayer, and FFmpeg. WebM is also supported by Blender, GIMP, and other digital media creation tools.

Features

WebM provides several features that make it an attractive alternative to other multimedia formats. One of the key features of WebM is its royalty-free status, which means that developers and content creators can use the format without having to pay licensing fees. WebM also provides support for HTML5 video and audio elements, making it easy to integrate into web pages and applications. Additionally, WebM provides support for 3D video and 360-degree video, as well as HDR and WCG color formats. WebM is also used by Google Street View, Google Earth, and other Google Maps services.

Software support

WebM is supported by a wide range of software applications, including Google Chrome, Mozilla Firefox, and Microsoft Edge. WebM is also supported by VLC media player, MPlayer, and FFmpeg, as well as Blender, GIMP, and other digital media creation tools. Additionally, WebM is supported by Android and iOS mobile operating systems, as well as Ubuntu, Debian, and other Linux distributions. WebM is also used by YouTube, Vimeo, and other online video platforms, as well as Wikipedia, Wikimedia Commons, and other Wikimedia Foundation projects.
