not.
the goal of that change was to add a new feature: filters can drop the frame.
i like it, and i'm about commiting that part.

ye sthis looks betterm but teh time calculations shouldn't be dropped by
return 0, so i've chanegd it to

ret=vf->put_image(vf,mpi)
if(ret>0) draw osd
calc timers
return ret;

agree
