Lauri Kasanen 681957b88d swscale/ppc: VSX-optimize yuv2rgb_full 
./ffmpeg -f lavfi -i yuvtestsrc=duration=1:size=1200x1440 \
        -s 1200x1440 -f null -vframes 100 -pix_fmt $i -nostats \
        -cpuflags 0 -v error -

This uses 32-bit mul, so POWER8 only.

The following output formats get about 4.5x speedup:
