Conditionally skip reference frame check For regular inter frames, if the distance from GOLDEN_FRAME is larger than 2 and if the predicted motion vector of LAST_FRAME gives lower sse than that of GOLDEN_FRAME, skip the GOLDE_FRAME mode checking in the rate-distortion optimization. It provides about 5% speed-up at expense of -0.137% and -0.230% performance down for speed 3.
