the vscaler works much better now than prevously, theres one bug left
in it though
./ffplay ./laraShadow_dl.flv -vf
scale=400x400:flags=16,fo
Attached patch with new vertical scaler code, added license and fixed
compiler warnings.

New patch with the green line bug fixed.
Now I intend to speedup the work on the vertical scaling and also try to
reduce
