One week after Google open sourced its $124.6m VP8 video codec, Mozilla and Opera have called for its inclusion in the still-gestating HTML5 specification. As it stands, the HTML5 spec does not specify a video codec. Browser makers are free to use any codec they like, and the big names are split between the patent-backed H.264 and the open source Ogg Theora. In open sourcing VP8 and rolling it into larger media format known as WebM, Google is hoping to create a single open and royalty-free standard for video compression on the web, and though it hasn't specifically called for VP8's inclusion in the HTML5 spec, Mozilla and Opera see no reason to wait.
