Discovered a blog post today from Philip Jägenstedt at Opera. The post describes the new HTML5 enabled Opera (alpha)( release and how it uses our favourite media framwork GStreamer. Great to see this available for easy download now and a big thanks to Opera for their work in supporting HTML5 and the Ogg codecs.
Philip got a lot of interesting details in that blog post so I really recommend reading it.

Opera also makes the source code of their copy GStreamer available as a git repo which should make merging any changes they do to GStreamer very easy, a big thanks for that.
