Hello,

just found out at
http://code.google.com/soc/2008/xorg/appinfo.html?csaid=ACD6AA025594454A
that :
"he purpose of this project is to produce a video decoding solution for
GPUs that are supported by the Gallium3D driver framework. The project
will attempt to implement the XvMC API using the programmable pipeline
of a typical GPU, thereby providing accelerated video decoding to a wide
variety of hardware. Since the decoding will be implemented using the
GPU's programmable pipeline, it is important to note that this solution
should support all recent GPUs regardless of whether or not they include
dedicated video decoding hardware. It is hoped that this GPU-based
acceleration will allow for real-time play back of HD video streams on
even modest hardware. The implementation will be developed and tested
using Gallium3D's SoftPipe driver, a stable software reference
implementation, and later Nvidia hardware and the Nouveau driver."

You can follow the progress at

Could be pretty usefull to lots of us :-)
