WebM, the open video standard introduced at Google's recent I/O developer conference, is now coming to Firefox 4. According Mozilla's Robert O'Callahan, the key sticking point was making sure that the new WebM codec licensing was compatible with GPL - an open-source licensing type that allows users to copy, modify and redistribute software free of charge as long as modifications made are shared with the community.

That issue has now been addressed, allowing Mozilla to support the codec in its Firefox Web browser.

oEmbed is a newly released spec from Cal Henderson (of Flickr), Mike Malone and Leah Culver (of Pownce), and Richard Crowley (of OpenDNS) that allows web sites to quickly and easily embed media when a user posts a link directly to that resource. oEmbed is an open format which standardizes the process of embedding photos, videos, links, or other media and circumvents the media provider's API (or the need for screen scraping if they don't offer one). It works by turning a link to, say, a photo or video into XML or JSON that tells the user how to embed that media.
