CODEC_CAP_DR1, well nothing special just proper use of get/release_buffer()
compared to returning random possibly static buffers ...
draw_horiz_band, is just called after each row of macroblocks is finished
(in the hope that it is still in the L2 cache for whatever is done with it
low_res, well decode in lower res what else :)
ill review the patch in a moment ...
