This is an initial attempt to allow variable block size partition in non-RD coding flow. It tests 8x8, 16x16 and 32x32 block size per 64x64 block, all using non-RD mode decision and the associated rate distortion costs from modeling, then selects the best block size to encode the entire 64x64 block. Such operations are triggered every other 3 frames. The blocks of intermediate frames will reuse the collocated block's partition type. It improves the compression performance by 13.2%. Note that the gains are not evenly distributed. For many hard clips, the compression performance is improved by 20% to 28%. Local speed test shows that it will also increase runtime by 50%, as compared to speed -7. It is now enabled in speed -6 setting. Change-Id: Ib4fb8659d21621c9075b3c369ddaa9ecb0a4b204 |
