In practice nobody outside a handful of developers and executives at rich tech firms seems to care about video codec licensing - open codecs were barely used anywhere until they matched the quality of the MPEG standards. They still aren't that widely used. H.264 is supposedly 90%+ of all digital video even now (well, as of a few years ago at least according to Google).
