Hi WebKit, I just wanted to let people know that I plan on updating the Media Source implementation to the new 0.4 spec<http://html5-mediasource-api.googlecode.com/svn/tags/0.4/draft-spec/mediasource-draft-spec.html>. The updated spec is intended to address a variety of concerns people had with the original 0.3 version<http://html5-mediasource-api.googlecode.com/svn/tags/0.3/draft-spec/mediasource-draft-spec.html>that got implemented. The update will be tracked as https://bugs.webkit.org/show_bug.cgi?id=83607. My plan is to first update the signatures of the existing methods and then follow up with the new methods as those features get implemented in the Chromium code. I believe this will provide the easiest migration path for people using the current implementation. The changes to WebKit should be relatively minor and primarily constitute changing existing method signatures and forwarding the new methods to the Chromium code. Aaron
