Hi!
So scaling actually works perfect to any width where width mod 16 =0.
In vf_scale.c put_image() it asks for vf_get_image but it asks for
aligning too, so width will be changed, aligned to 16 byte boundaries - but
none of the vo_* no about the change.
So if I use scale=272:0 all is good!
Would you like a patch for this perhaps? An awfull disgusting messy hack ?:)
best regards
Denes
