yep they weren't designed to do it, but for teh drop-deinterlacer filter it
was hacked a bit, so it should be possible.
at least with mencoder, it could work. the filter may call next_put_image()
more times than its put_image() called, and since the last filter in the
queue is ve_* calling mux_*, the outgoing timers will be correct.

anyway for framerate duplication you may need to pass -ofps option.

note: all this unetsted, just speculation.

note2: it won't work with mplayer, since it assumes 0 or 1 frames from 1
decode_frame() call (and calls libvo's blit function only once).
anyway i'm planning to add -ofps option to mplayer too.
