Lightspark progresses are never been so good. The last achievement was to correctly load, execute and partially render the YouTube player. As you may have seen YouTube has recently switched to Flash 10 and ActionScript 3.0 to serve some HD content, while keeping the old AS2 based player for lower quality videos. The old player is supported by Gnash but, until now, there where no open source alternatives to play newer, high definition content. As Lightspark AS3 engine matures, that gap is almost closed. Stay tuned, as I’m planning to release a new technology demo very soon.
UPDATE: Demo tarball released on sourceforge
