With the glamo hw you can do mpeg4 decoding acceleration but not mpeg1/2? Isn't mpeg4 in hw theoretically more difficult (from the raw computing point of view) than mpeg1/mpeg2 decoding? Just for curiosity of course. Anyway, out the video playback issue, I looked at some of this hw-specific code in the mplayer git branch or in Xglamo, it sounds pretty interesting. (I have played a lot with some graphic cards accel in the late 90s: Matrox or Cirrus Logic primarily.) 2D accel for example should really help the overall phone UI operation no? What is the overall objective on the Neo: have a glamo-specific X server using XAA and the like (hence an X driver), or implement most of the hw acceleration in the framebuffer device and use Xfbdev (hence a kernel driver), or something else (possibly more recent than my experience with this area ;-)?
