   "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
