Defines the parameters used to perform txfm search.
For the most part, this determines how various speed features are used.
int TxfmSearchParams::use_default_intra_tx_type |
Whether to limit the intra txfm search type to the default txfm.
This could either be a result of either sequence parameter or speed features.
int TxfmSearchParams::use_default_inter_tx_type |
Whether to limit the inter txfm search type to the default txfm.
This could either be a result of either sequence parameter or speed features.
unsigned int TxfmSearchParams::coeff_opt_thresholds[2] |
Variable from WinnerModeParams based on current eval mode.
See the documentation for WinnerModeParams for more detail.
unsigned int TxfmSearchParams::tx_domain_dist_threshold |
Variable from WinnerModeParams based on current eval mode.
See the documentation for WinnerModeParams for more detail.
TX_SIZE_SEARCH_METHOD TxfmSearchParams::tx_size_search_method |
Variable from WinnerModeParams based on current eval mode.
See the documentation for WinnerModeParams for more detail.
unsigned int TxfmSearchParams::use_transform_domain_distortion |
Variable from WinnerModeParams based on current eval mode.
See the documentation for WinnerModeParams for more detail.
unsigned int TxfmSearchParams::skip_txfm_level |
Variable from WinnerModeParams based on current eval mode.
See the documentation for WinnerModeParams for more detail.
TX_MODE TxfmSearchParams::tx_mode_search_type |
How to search for the optimal tx_size.
If ONLY_4X4, use TX_4X4; if TX_MODE_LARGEST, use the largest tx_size for the current partition block; if TX_MODE_SELECT, search through the whole tree.

unsigned int TxfmSearchParams::predict_dc_level |
Flag to enable/disable DC block prediction.
