put_image() in libmpcodecs/vf_vo.c calls draw_slice.

In video_to_output_surface(), the VDPAU mixer gets the necessary data to be able
to render a picture on an output_surface, flip_page (called from mplayer.c)
displays it.

These were MPlayer questions, for VDPAU questions please see
/usr/include/vdpau.c,
ftp://download.nvidia.com/XFree86/vdpau/doxygen/html/index.html or post a
question on http://www.nvnews.net/vbulletin/forumdisplay.php?f=14 .
