"Hardware acceleration" usually means hardware YUV conversion, scaling,
bilinear filtering. Under Linux, there are several ways to access it:
-I. the Xv (XVideo) extension of XFree86-4.0.x
-II. opengl drivers with glTexSubImage() support (currently the Utah-GLX drivers)
-III. native card-specific drivers, using special abilities of some cards
