What is webm?
WebM is a multimedia container format designed to provide a high-quality, royalty-free video compression format for use with HTML5 video. The development of the project is sponsored by Google. A WebM file consists of VP8 video and Vorbis audio, in a container based on a Matroska profile. The project launches related WebM software under a BSD license, and all users receive a royalty-free, non-exclusive, worldwide non-exclusive patent license. The purpose of the repository is to maintain the video and audio streams, so that they can be synchronized for playback. The container is comparable to a QuickTime or MPEG4 file.
What is the VP8 video codec?
VP8 is a highly efficient video compression technology developed by On2 Technologies. Google acquired On2 in February 2010. For more information, see the “VP8 Video Codec” section below.
What is the Vorbis audio codec?
Vorbis is an open source audio compression technology. It is an independent project of the Xiph Foundation. For more information on Vorbis, visit www.vorbis.org.
A valid WebM file can only contain VP8 video and Vorbis audio in a webm container.
