/*!\brief AV1 motion mode search
*
* \ingroup inter_mode_search
* Function to search over and determine the motion mode. It will update
* mbmi->motion_mode to one of SIMPLE_TRANSLATION, OBMC_CAUSAL, or
* WARPED_CAUSAL and determine any necessary side information for the selected
* motion mode. It will also perform the full transform search, unless the
* input parameter do_tx_search indicates to do an estimation of the RD rather
* than an RD corresponding to a full transform search. It will return the
* RD for the final motion_mode.
* Do the RD search for a given inter mode and compute all information relevant
* to the input mode. It will compute the best MV,
* compound parameters (if the mode is a compound mode) and interpolation filter
* parameters.
*
* \param[in] cpi Top-level encoder structure.
* \param[in] tile_data Pointer to struct holding adaptive
* data/contexts/models for the tile during
* encoding.
* \param[in] x Pointer to struct holding all the data for
* the current macroblock.
* \param[in] bsize Current block size.
* \param[in,out] rd_stats Struct to keep track of the overall RD
* information.
* \param[in,out] rd_stats_y Struct to keep track of the RD information
* for only the Y plane.
* \param[in,out] rd_stats_uv Struct to keep track of the RD information
* for only the UV planes.
* \param[in] args HandleInterModeArgs struct holding
* miscellaneous arguments for inter mode
* search. See the documentation for this
* struct for a description of each member.
* \param[in] ref_best_rd Best RD found so far for this block.
* It is used for early termination of this
* search if the RD exceeds this value.
* \param[in,out] ref_skip_rd A length 2 array, where skip_rd[0] is the
* best total RD for a skip mode so far, and
* skip_rd[1] is the best RD for a skip mode so
* far in luma. This is used as a speed feature
* to skip the transform search if the computed
* skip RD for the current mode is not better
* than the best skip_rd so far.
* \param[in,out] rate_mv The rate associated with the motion vectors.
* This will be modified if a motion search is
* done in the motion mode search.
* \param[in,out] orig_dst A prediction buffer to hold a computed
* prediction. This will eventually hold the
* final prediction, and the tmp_dst info will
* be copied here.
* \param[in,out] best_est_rd Estimated RD for motion mode search if
* do_tx_search (see below) is 0.
* \param[in] do_tx_search Parameter to indicate whether or not to do
* a full transform search. This will compute
* an estimated RD for the modes without the
* transform search and later perform the full
* transform search on the best candidates.
* \param[in] inter_modes_info InterModesInfo struct to hold inter mode
* information to perform a full transform
* search only on winning candidates searched
* with an estimate for transform coding RD.
* \param[in] eval_motion_mode Boolean whether or not to evaluate motion
* motion modes other than SIMPLE_TRANSLATION.
* \return Returns INT64_MAX if the determined motion mode is invalid and the
* current motion mode being tested should be skipped. It returns 0 if the
* motion mode search is a success.

/*!\brief AV1 inter mode RD computation
*
* \ingroup inter_mode_search
* Do the RD search for a given inter mode and compute all information relevant
* to the input mode. It will compute the best MV,
* compound parameters (if the mode is a compound mode) and interpolation filter
* parameters.
*
* \param[in] cpi Top-level encoder structure.
* \param[in] tile_data Pointer to struct holding adaptive
* data/contexts/models for the tile during
* encoding.
* \param[in] x Pointer to structure holding all the data
* for the current macroblock.
* \param[in] bsize Current block size.
* \param[in,out] rd_stats Struct to keep track of the overall RD
* information.
* \param[in,out] rd_stats_y Struct to keep track of the RD information
* for only the Y plane.
* \param[in,out] rd_stats_uv Struct to keep track of the RD information
* for only the UV planes.
* \param[in] args HandleInterModeArgs struct holding
* miscellaneous arguments for inter mode
* search. See the documentation for this
* struct for a description of each member.
* \param[in] ref_best_rd Best RD found so far for this block.
* It is used for early termination of this
* search if the RD exceeds this value.
* \param[in] tmp_buf Temporary buffer used to hold predictors
* built in this search.
* \param[in,out] rd_buffers CompoundTypeRdBuffers struct to hold all
* allocated buffers for the compound
* predictors and masks in the compound type
* search.
* \param[in,out] best_est_rd Estimated RD for motion mode search if
* do_tx_search (see below) is 0.
* \param[in] do_tx_search Parameter to indicate whether or not to do
* a full transform search. This will compute
* an estimated RD for the modes without the
* transform search and later perform the full
* transform search on the best candidates.
* \param[in,out] inter_modes_info InterModesInfo struct to hold inter mode
* information to perform a full transform
* search only on winning candidates searched
* with an estimate for transform coding RD.
* \param[in,out] motion_mode_cand A motion_mode_candidate struct to store
* motion mode information used in a speed
* feature to search motion modes other than
* SIMPLE_TRANSLATION only on winning
* candidates.
* \param[in,out] skip_rd A length 2 array, where skip_rd[0] is the
* best total RD for a skip mode so far, and
* skip_rd[1] is the best RD for a skip mode so
* far in luma. This is used as a speed feature
* to skip the transform search if the computed
* skip RD for the current mode is not better
* than the best skip_rd so far.
* \param[in] inter_cost_info_from_tpl A PruneInfoFromTpl struct used to
* narrow down the search based on data
* collected in the TPL model.
*
* \return The RD cost for the mode being searched.
