This is what I am doing.

This is more difficult, and becomes an architecture issue which I will
defer to you.  Right now, the vfilter stuff is not "exposed" to the
mplayer core.

- sh_video->vfilter is a void * and needs to be cast to dereference
  control() from it
  - when trying to cast it, vf_instance_t is not available to
    mplayer.c
- VFCTRL_ macros are not available to mplayer.c

Do you want to simply expose the vf_instance_t type (and it's required
sub-types) to mplayer.c or do you want to abstract it through some
other way?

Again, this would require the vfilter interface to be exposed in
mplayer.c.

Please advise,
