This commit makes the encoder to select between SATD/variance as metric for mode decision. It also allows to account chroma component costs for mode decision as well. The overall encoding time increase as compared to variance based mode selection is about 15% for speed -6. The compression performance is on average 2.2% better than variance based approach, with about 5% compression performance gains for hard clips (e.g., jimredvga, nikas720p, and mmmoving) at lower bit-rate range.
