This patch fixes a regression introduced in 1d190950 where the encoder was using the 16x16 VP9/AV1 transforms for RDO, but then used the Daala transforms for encoding. subset1: master-daala_dct16@2017-09-13T12:05:18.013Z -> master_daala_dct16_use_c@2017-09-13T13:05:02.252Z PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 -0.3654 | -0.7634 | -0.7407 | -0.4884 | -0.4699 | -0.4945 | -0.5104 master-no_rect_tx-no_var_tx@2017-09-12T00:23:18.153Z -> master_daala_dct16_use_c@2017-09-13T13:05:02.252Z PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 -0.0133 | 0.1040 | -0.0440 | -0.0492 | -0.0151 | -0.0120 | 0.0699 Change-Id: Id1830d0975db4bd0320a47fdf45b4bca20881cfb

This allows a mask for mrc-tx to be sent in the bitstream for inter or intra 32x32 transform blocks. The option to send the mask vs build it from the prediction signal is currently controlled with a macro. In the future, it is likely the macro will be removed and it will be possible for a block to select either method. The mask building functions are still placeholders and will be filled in in a followup. Change-Id: Ie27643ff172cc2b1a9b389fd503fe6bf7c9e21e3

This patch fixes a regression introduced in 1d190950 where the encoder was using the 4x4 VP9/AV1 transforms for RDO, but then used the Daala transforms for encoding. The ~2% improvement below comes from forcing the C implementation of the 4x4 and 8x8 transforms to be used when CONFIG_DAALA_DCT4 and CONFIG_DAALA_DCT8 are enabled respectively. subset-1 (--enable-experimental --enable-daala_dct4): master@2017-08-21T21:41:18.302Z -> master_daala_dct4_use_c@2017-08-22T02:39:14.457Z PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 -2.1953 | -1.2044 | -1.1865 | -1.6173 | -1.7029 | -1.6784 | -1.7235 Change-Id: I44d2b24094e89b2857ae03d743180e706cef45eb

Change get_lgt in order to integrate a later experiment lgt_from_pred with lgt. There are two main changes. The main purpose for this change is to unify get_fwd_lgt and get_inv_lgt functions into a get_lgt function so the lgt basis functions can always be selected through the same function in both forward and inverse transform paths. The structure of those functions will also be consistent with the get_lgt_from_pred functions that will be added in the lgt-from-pred experiment. These changes have no impact on the bitstream.

If the mask is invalid, do not allow the encoder to select MRC_DCT. Currently the mask is invalid if it is all 1 or all 0, but these criteria will likely expand in a future patch. Change-Id: I77230ea8357bfdb2bf1e6338903d44bbf1db22d1

This experiment aims at merging lbd/hbd txfms So far this exp uses hbd transform on lbd path. The performances I observed are lowres -0.089% midres 0.065% (negative means performance drop) Started from here, two main things are needed to be done. 1) Fix overflow due to quantizer noise 2) Generate a 16-bit version from the hbd txfm Change-Id: I35bb1fc0cbb78decad2570ff5826ed665f739752

MRC_DCT uses a mask based on the prediction signal to modify the residual before applying DCT_DCT. This adds all necessary functions to perform this transform and makes the prediction signal available to the 32x32 txfm functions so the mask can be created. I am still experimenting with different types of mask generation functions and so this patch contains a placeholder. This patch has no impact on performance.

This experiment replaces the 8-point Type-II DCT and 8-point Type-IV DST scaling vp9 transforms with the 8-point orthonormal Daala transforms. These have reduced complexity and are perfect reconstruction at the cost of a slightly worse coding performance. This is because the Daala transforms expect the input to be shifted by 4 bits but the output scale of the vp9 transforms is only 3 bits. subset-1: monty-square-baseline-subset1 -> monty-square-dct8-subset1@2017-07-17T21:37:44.281Z PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 0.0019 | -0.0011 | -0.0585 | -0.0111 | 0.0305 | 0.0317 | 0.0187 objective-1-fast: monty-square-baseline-o1f -> monty-square-dct8-o1f@2017-07-17T21:37:15.735Z PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 0.0285 | 0.0129 | -0.5080 | 0.0529 | 0.0345 | 0.0441 | 0.0054 Change-Id: I2b775495398fb717204a295397c3c5e3ca938183

This adds the new transform to the list of possible transforms. The impact on performance is in the noise range because the transform implementation currently performs DCT as a placeholder. This transform will initially only have an implementation for TX_32X32 and it is skipped in the tx search for smaller transform sizes. Change-Id: Iab2faddc525b478ca06972a753428a4f4ef53ac6

Change two similar structs, FWD_TXFM_PARAM and INV_TXFM_PARAM, into a common struct: TxfmParam. Its definition is moved to aom_dsp/txfm_common.h to simplify dependency. This change is made so that, in later changes of the LGT experiment, functions requiring FWD_TXFM_PARAM and INV_TXFM_PARAM, such as get_fwd_lgt4 and get_inv_lgt4, can also be unified.
