| /*!\brief AV1 motion mode search |
| * |
| * \ingroup inter_mode_search |
| * Function to search over and determine the motion mode. It will update |
| * mbmi->motion_mode 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. |
