Which way did you try this?
I would have assumed that a combination of panscan and border_pos would
have this effect...
In fact, wouldn't (ignoring division by 0, rounding etc.
vo_border_pos_x = vo_fs_border_l / (vo_fs_border_l + vo_fs_border_r)
vo_border_pos_y = vo_fs_border_t / (vo_fs_border_t + vo_fs_border_b)
and
*w -= vo_fs_border_l + vo_fs_border_r;
*h -= vo_fs_border_t + vo_fs_border_b
in get_max_dims (aspect.c)
have the desired effect?
