Last night Adobe pushed out their first beta release for Adobe Flash Player 10.1. Alongside the Windows and Mac OS X beta releases was a 32-bit Linux build, but the 64-bit build isn't yet available so those users will need to be use the earlier 64-bit beta. One of the main features for Flash Player 10.1 is H.264 hardware video acceleration support, which is sadly missing from the Linux version.
On the Windows version Adobe is accelerating H.264 with UVD2 for ATI Radeon graphics hardware, NVIDIA hardware with PureVideo, Intel GMA 4-Series acceleration support, and even Broadcom video acceleration support via their Crystal HD Enhanced Video Accelerator.
