I have fixed this problem. It seems I misunderstood the mplayer dr1 logic. 
If vd_ffmpeg.c specifically enforced do_dr1 to 0 for H.264, it was for a 
reason. So, I also dropped the draw_horiz_band=vaapi_render_frame() hack I 
borrowed from VDPAU and XvMC cases.

IOW, VA API (Intel) now correctly plays all H.264 streams I have here.

Gwenole.
