[theora-dev] Using i915/i945 XvMc in Theora

Hi,

Intel has recently open sourced  otion compensation code (XvMC) for
their i915/i945 integrated graphics chips.

See:
http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-intel.git;a=blob;hb=xvmc-i915;f=src/xvmc/I915XvMC.c

XvMC API was intended for MPEG{2,4} class of codecs - so it can not be
used for Theora as-is. However, could at least some parts of it such as
hardware accelerated YUV->RGB conversion be utilized, by exposing them
through custom interface?

Regards
Zoran
