This is a really interesting bit of news that I just picked up over on http://www.DesktopLinux.com:
Adobe is added MPEG4 video support to it’s Flash 9 player, including the Linux version.
In what promises to boost video quality in desktop, mobile, and embedded devices, Adobe announced that it has added H.264 support to its popular Flash Player software. “Flash Player 9, Update 3 beta,” available for download from Adobe’s Labs website, supports Linux, OS X, and Windows.
