32 bits, depth==24, screen size 640x480.

code is:

  visual_input_run (libvis->input);
  visual_video_set_buffer (libvis->video, pixel_data);
  visual_actor_run (libvis->actor, libvis->input->audio);

This generally runs OK.

If you need some help with jack, look at jack.c in LiVES, in particular 
jack_open_device(). I will shortly be adding code to grab audio from jack.


Hope this helps,
Gabriel.
