In Drupal 7, media_archive leverages the Media module and its media management framework including WYSIWYG integration. The D7 branch is still very much in development, but works for browsers that support the HTML5 video tag with Ogg or MPEG4. Yeah iOS support for video! Sorry IE6 and audio users :( Eventually IE6 users will see the Archive.org Flowplayer for video. We're still trying to figure out audio as well as PDF, images, and other content types Archive.org and Media both support. There is currently no upgrade path from emfield to Media.
