It wouldn't matter if they did release this information. IDCT is the
inverse discrete cosine transform; that is, the inverse of the DCT, used
by the MPEG encoding process. It would still be good if ATI released
info on their IDCT processor: the software DVD player writers could use
it to speed up their decoding.
To the original poster: since ATI's MPEG encoder is entirely in
software, there's really nothing to lobby ATI for. Just find a software
MPEG encoder for Linux that operates in real time. Trivial. :)
Bonus hint: SAMPEG, mentioned at linuxtv.org, will become real time in
about 6 years, assuming that Moore's law holds, and that the software
remains unoptimized.
