1. Fixes logic for disabling global motion w/ resize. Turns off conditional write/read of global parameters since it does not work currenlty. To be fixed later. 2. Fixes call for av1_scale_if_required in encoder_frame_with_resize function 3. Remove asserts for the scaled convolve functions Change-Id: I6a0f18b5ab5cc819bc27ef9fc2f28b0e391643a0

* Reduce bit widths of intermediate values where possible * Change ROUND_POWER_OF_TWO_SIGNED to ROUND_POWER_OF_TWO in av1(_highbd)_convolve_2d * Apply offsetting and bounds checking, to match the intended hardware implementation * Separate the implementations of av1(_highbd)_convolve_2d into compound-round and non-compound-round cases. This is because there are now a significant number of differences between the functions. Overall, this is expected to affect the bitstream and encoder output when convolve-round alone is enabled, but *not* when compound-round is enabled.

The 'ref' member of ConvolveParams currently serves two purposes: * To indicate which component of a compound we're currently predicting, eg. for fetching interpolation filters with dual-filter enabled. * To determine whether we should average into the destination buffer. But there are two cases where we want to separate these out: * In joint_motion_search, we want to try combining a fixed second prediction with various first predictions. * When searching masked interinter compounds, we want to predict each component separately then try different combinations. In these cases, we set 'ref' to 0 and use temporary variables to make sure we use the correct interpolation filters. But this is quite fragile. This patch separates out the two uses into separate members. This allows us to remove some temporary variables, but more importantly gives easy fixes to two bugs in build_inter_predictors_single_buf (used by rdopt): * We previously set ref=0 but didn't fix up the interpolation filters * For ZERO_ZEROMV modes, the second component would accidentally average into the (uninitialized!) second prediction buffer BUG=aomedia:577 BUG=aomedia:584 BUG=aomedia:595 Change-Id: Ibc31d1ac701a029ea5efaa1197dd402bc4b7af1e

The SSE3 convolve functions do not work when scaling is involved. If either x_step_q4 or y_step_q4 is not 16 scaling will occur and an assert fails. This patch creates a C version of av1_convolve, av1_convolve_c. This function in turn calls all C versions of what av1_convolve calls. New C versions of these called functions have been created where needed and the same for the functions they call. This means that when scaling is enabled no asserts fail. av1_convolve_c is called instead of av1_convolve when x_step_q4 or y_step_q4 is not 16. Change-Id: I604d2716e034e23a0553fb7004133d3075514a7a

When convolve_round is on, av1_convolve_2d_facade will be used for interpolation rather than av1_convolve. Will remove the experiment code of convolve_round experiment from av1_convolve in another CL. So far we use 4-bit rounding in the intermediate stage on top of using post rounding for compound mode after the last stage. This will give us roughly 0.45% gain on lowres , 0.39% on midres and roughly 0.6-0.7% on hdres Altogether, is 1.15% on lowresm, 0.74% on midres and roughly 1.7-1.8% on hdres Note that there no restriction usage of 12-tap filter in the CL. Adding that, we will lose roughly 0.1% again on lowres. Change-Id: I6332e1d888e28a3b3ddc29711817d66e52cb5cdf
