Enable 16x16 Hadamard transform in SATD based mode decision This commit replaces the 16x16 2D-DCT transform with Hadamard transform for RTC coding mode. It reduces the CPU cycles cost on 16x16 transform by 5X. Overall it makes the speed -6 encoding speed 1.5% faster without compromise on compression performance.
