Lauri Kasanen 8522d219ce libswscale/ppc: VSX-optimize 9-16 bit yuv2planeX ... ./ffmpeg_g -f rawvideo -pix_fmt rgb24 -s hd1080 -i /dev/zero -pix_fmt yuv420p16be \ -s 1920x1728 -f null -vframes 100 -v error -nostats - 9-14 bit funcs get about 6x speedup, 16-bit gets about 15x. Fate passes, each format tested with an image to video conversion. Only POWER8 includes 32-bit vector multiplies, so POWER7 is locked out of the 16-bit function. This includes the vec_mulo/mule functions too, not just vmuluwm.
