There will never be a single standard video codec until the last video codec developer has retired. As long as there is ongoing effort to write better codecs, there will be multiple codecs in use at any given time. What's important is that you can encode your video in Theora or VP8 and expect it to work in modern browsers (Firefox, Chrom{e,ium}, Opera, etc). In a year or two VP9 will be just as supported, and then you can switch to it.
