They work fantastically well together. Scott Davilla, who is the one that got the ball rolling on open-sourcing the crystalhd driver and library and brought me into the fold, has done an outstanding job with the xbmc development trunk code, adding support for offloading decoding to the crystalhd. I grabbed the Big Buck Bunny 1080p h.264 clip and threw it at a build of today’s xbmc on an x86_64 Fedora 12 install on my Lenovo ThinkPad T61 (sporting a Core 2 Duo processor at 2.2GHz and Intel X3100 graphics), and the system hardly broke a sweat, topping out at 39% cpu usage, with absolutely flawless decoding and perfectly smooth playback. Juxtapose this with mplayer operating on the same file, pegging one cpu core, with obvious dropped frames, stuttering, etc. Good stuff.
