December 29, 2007 - After making available the documentation of its Radeon graphics processors to the open source community, AMD now will also release information on accelerated video playback.
In the Phoronix forums, John Bridgman of ATI's Software Development Engineering Group stated that they will be releasing IDCT (Inverse Discrete Cosine Transform) and MC (Motion Compensation) information for everything up to and including the Radeon X1000 (R500) series. This can be used for hardware-assisted video decoding.
The same will most likely not happen for the R600 and R700 series, since the H.264 and VC-1 video decoding is combined with the Digital Rights Management functionality (DRM) in the Unified Video Decoder unit (UVD). However, Bridgman confirms that future Radeon GPUs will be more open, even if this requires developing a modular version of the UVD.
