It's not a dupe. The previous release was a marketing fluff. Now people can actually start encoding video without having to worry about having to do everything over. That is a big deal. The previous announcement was a complete non-event.

Incidentally, Bunny's NeTV2 [1] might be a convenient platform for a hardware accelerated codec.
