this patch works exactly as I need (mplayer -fps 1 file.m2v 
shows the stills with 0 delay without setting low_delay in 
the flags),
but I don't know if it's even remotely acceptable or how 
much it sucks, apologies in advance :)

The seq_end_code is stored at the end of the frame, and 
based on its presence slice_end() works as if low_delay was set;
ff_draw_horiz_band() works on ->current_picture_ptr if
the codec is mpeg12 && pict_type== I_frame and ->temp_ref==0
(that should be true for all mpeg12 stills).
If this method is wrong I'd like to have some direction, 
please :) At the moment I'm just stabbing in the dark
