AV1 inter mode selection.

Top level function for inter mode selection. This function will loop over all possible inter modes and select the best one for the current block by computing the RD cost. The mode search and RD are computed in handle_inter_mode(), which is called from this function within the main loop.

Parameters

  [in] | cpi | Top-level encoder structure
  [in] | tile_data | Pointer to struct holding adaptive data/contexts/models for the tile during encoding
  [in] | x | Pointer to structure holding all the data for the current macroblock
  [in] | rd_cost | Struct to keep track of the RD information
  [in] | bsize | Current block size
  [in] | ctx | Structure to hold snapshot of coding context during the mode picking process
  [in] | best_rd_so_far | Best RD seen for this block so far

Remarks
  Nothing is returned. Instead, the MB_MODE_INFO struct inside x is modified to store information about the best mode computed in this function. The rd_cost struct is also updated with the RD stats corresponding to the best mode found.

AV1 motion 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.

Parameters

  [in] | cpi | Top-level encoder structure.
  [in] | tile_data | Pointer to struct holding adaptive data/contexts/models for the tile during encoding.
  [in] | x | Pointer to struct holding all the data for the current macroblock.

  [in,out] | rd_stats_uv | Struct to keep track of the RD information for only the UV planes.
  [in] | args | HandleInterModeArgs struct holding miscellaneous arguments for inter mode search. See the documentation for this struct for a description of each member.

  [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.
  [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.
  [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.
  [in,out] | best_est_rd | Estimated RD for motion mode search if do_tx_search (see below) is 0.
  [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.
  [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.
  [in] | eval_motion_mode | Boolean whether or not to evaluate motion motion modes other than SIMPLE_TRANSLATION.

| inline static

Prunes ZeroMV Search Using Best NEWMV's SSE.

Compares the sse of zero mv and the best sse found in single new_mv. If the sse of the zero_mv is higher, returns 1 to signal zero_mv can be skipped. Else returns 0.

Note that the sse of here comes from single_motion_search. So it is interpolated with the filter in motion search, not the actual interpolation filter used in encoding.

Parameters

  [in] | fn_ptr | A table of function pointers to compute SSE.
  [in] | x | Pointer to struct holding all the data for the current macroblock.
  [in] | bsize | The current block_size.
  [in] | args | The args to handle_inter_mode, used to track the best SSE.
  [in] | prune_zero_mv_with_sse | The argument holds speed feature prune_zero_mv_with_sse value

Returns
  Returns 1 if zero_mv is pruned, 0 otherwise.

Searches for interpolation filter in realtime mode during winner eval.

Does a simple interpolation filter search during winner mode evaluation. This is currently only used by realtime mode as av1_interpolation_filter_search is not called during realtime encoding.

This function only searches over two possible filters. EIGHTTAP_REGULAR is always search. For lowres clips (<= 240p), MULTITAP_SHARP is also search. For higher res slips (>240p), EIGHTTAP_SMOOTH is also searched.

- Parameters

    [in] | cpi | Pointer to the compressor. Used for feature flags.
    [in,out] | x | Pointer to macroblock. This is primarily used to access the buffers.
    [in] | mi_row | The current row in mi unit (4X4 pixels).
    [in] | mi_col | The current col in mi unit (4X4 pixels).
    [in] | bsize | The current block_size.

  Returns
    Returns true if a predictor is built in xd->dst, false otherwise.
