./ffmpeg -i lena.pnm -s 4096x2048 test.mp4
segfaults

./ffmpeg -i fate-suite/cine/bayer_gbrg8.cine  -vf scale=300:300 -vframes 1 img.jpg
all green image

./ffplay -i ~/videos/lena.pnm -vf format=yuv410p
mostly green

also please submit patches more often than once a week(as theres
little time left) and if you
easily can then please split the patch into one for horizontal and
one for vertical. But if this is alot of work then leave it rather
in one patch.
For example if you could get the horizontal code bug free without
speed regression then that could be pushed and the amount of
code to work on would be half ...

It is what and why we do it that matters, not just one of them.
