I think they are in the same thread.

Call chain for flip_page is:
   main (in mplayer.c)
-> flip_page

for draw_image is:
   main -> update_video [-> generate_video_frame] (in mplayer.c)
-> filter_video (in libmpcodecs/dec_video.c)
-> put_image (in vf's, the last is in vf_vo.c)
-> control -> draw_image (in vo)

Since code in mplayer.c itself do not spawn any threads, and filters
seem not to spawn threads as well, they should run in the same thread.
