Skip the partition search for the frame with no motion This patch allows the encoder to skip the partition search for the frame if it is an inter frame and only zero motion vectors have been detected in the first pass. The partition size is directly assigned according to the difference variance. Borg tests show overall little performance changes in term of PSNR (derf -0.027%, yt 0.152%, hd 0.078%, stdhd 0%). The worst case of PSNR loss is -0.514% from yt. The best PSNR gain is 4.293% from yt. The second pass encoding speedup for slideshow clips is 15%-40%.
