av_cold void ff_rv40dsp_init_x86 (RV34DSPContext *c)
 

Detailed Description

RV40 decoder motion compensation functions x86-optimised 2,0 and 0,2 have h264 equivalents. 3,3 is bugged in the rv40 format and maps to _xy2 version

Define one qpel function.

LOOPSIZE must be already set to the number of pixels processed per iteration in the inner loop of the called functions. COFF(x) must be already defined so as to provide the offset into any array of coeffs used by the called function for the qpel position x.
