Google Reader to Support for Video and Audio Tags
Google’s feed reader started to support the video and audio tags from feeds. The only popular browser that doesn’t support the two tags is Internet Explorer, but that doesn’t mean that you’ll be able to play videos without plug-ins in all the other browsers.
As the screenshot below shows, Firefox and Opera don’t support the H.264 compression standard, so you can’t play videos from sites that only use H.264. Even if video sites like YouTube or Vimeo started to test HTML5 players, they don’t offer the option to embed videos using HTML5 tags.
