Phoronix: An Update On Generic GPU Video Decoding

One of Google's Summer of Code projects this year is to bring hardware-based video acceleration to Linux with Gallium3D. The advantage of this design is that the implementation is designed to be universal to any driver using Gallium3D, which for now is largely just the Nouveau driver and an experimental Intel version.With many of the open-source drivers currently lacking any form of GPU-based video decoding acceleration (such as XvMC or the forthcoming VA-API), this will be a terrific feature as it will provide this functionality once the drivers make the switch to Tungsten's Gallium3D as this method doesn't require any hardware/driver-specific work...
