It seems current implantation of Altivec doesn't support little-endian.
FFmpeg was compiled as:
./configure --prefix=/usr --extra-libs="-lpthread -lm" --enable-gpl
--enable-libvpx --enable-libx264 --enable-nonfree --enable-shared
--enable-avresample
Run time options:
ffmpeg -i ./Sintel.mp4 -filter:v fps=fps=1/60 /tests/before/frames/%0d.png
