## Detailed Description

Encoder parameters related to multi-threading.

## Field Documentation

## ◆ num_workers

int MultiThreadInfo::num_workers

Number of workers created for multi-threading.

Referenced by encode_frame_internal().

## ◆ num_mod_workers

int MultiThreadInfo::num_mod_workers[NUM_MT_MODULES]

Number of workers used for different MT modules.

Referenced by cdef_restoration_frame(), encode_frame_internal(), and loopfilter_frame().

## ◆ workers

AVxWorker* MultiThreadInfo::workers

Synchronization object used to launch job in the worker thread.

Referenced by cdef_restoration_frame(), and loopfilter_frame().

## ◆ tile_thr_data

struct EncWorkerData* MultiThreadInfo::tile_thr_data

## ◆ row_mt_enabled

bool MultiThreadInfo::row_mt_enabled

When set, indicates that row based multi-threading of the encoder is enabled.

Referenced by encode_frame_internal(), and encode_sb_row().

## ◆ pack_bs_mt_enabled

bool MultiThreadInfo::pack_bs_mt_enabled

When set, indicates that multi-threading for bitstream packing is enabled.

Referenced by encode_frame_internal().

## ◆ enc_row_mt

AV1EncRowMultiThreadInfo MultiThreadInfo::enc_row_mt

Encoder row multi-threading data.

Referenced by encode_frame_internal(), encode_sb_row(), pick_sb_modes(), and pick_sb_modes_nonrd().

AV1TplRowMultiThreadInfo MultiThreadInfo::tpl_row_mt

Tpl row multi-threading data.

## ◆ lf_row_sync

AV1LfSync MultiThreadInfo::lf_row_sync

Loop Filter multi-threading object.

Referenced by loopfilter_frame().

## ◆ lr_row_sync

AV1LrSync MultiThreadInfo::lr_row_sync

Loop Restoration multi-threading object.

Referenced by cdef_restoration_frame().

## ◆ pack_bs_sync

AV1EncPackBSSync MultiThreadInfo::pack_bs_sync

Pack bitstream multi-threading object.

## ◆ gm_sync

AV1GlobalMotionSync MultiThreadInfo::gm_sync

Global Motion multi-threading object.

## ◆ tf_sync

AV1TemporalFilterSync MultiThreadInfo::tf_sync

Temporal Filter multi-threading object.

## ◆ cdef_sync

AV1CdefSync MultiThreadInfo::cdef_sync

CDEF search multi-threading object.

Referenced by cdef_restoration_frame().

## ◆ cdef_worker

AV1CdefWorkerData* MultiThreadInfo::cdef_worker

Pointer to CDEF row multi-threading data for the frame.

Referenced by cdef_restoration_frame().

## ◆ restore_state_buf

RestoreStateBuffers MultiThreadInfo::restore_state_buf

Buffers to be stored/restored before/after parallel encode.

## ◆ pipeline_lpf_mt_with_enc

int MultiThreadInfo::pipeline_lpf_mt_with_enc

In multi-threaded realtime encoding with row-mt enabled, pipeline loop-filtering after encoding.

Referenced by encode_with_recode_loop_and_filter(), and loopfilter_frame().
