I added the MOD 2 to the "h" and "w" variables to ensure that the
resulting calculated height and width is always divisible by two:
if (w == -1)
w = av_rescale(h, inlink->w, inlink->h) + ( av_rescale(w,
inlink->h, inlink->w) % 2 );
if (h == -1)
h = av_rescale(w, inlink->h, inlink->w) + ( av_rescale(w,
inlink->h, inlink->w) % 2 );
Appears to work great for me.
