  "message": "Fix tpl stored ref frame indices\n\nSome details on this:\n\n- gf_group-\u003eref_frame_list stores the absolute slot idx from ext rc;\n\nAnd:\n\n- src_stats-\u003eref_frame_index comes from best_rf_idx in function mode_estimation;\n- best_rf_idx was used to retrieve the ref like this:\n    const YV12_BUFFER_CONFIG *ref_frame_ptr \u003d tpl_data-\u003esrc_ref_frame[rf_idx];\n- tpl_data-\u003esrc_ref_frame[rf_idx] comes from tpl_data-\u003etpl_frame[tpl_frame-\u003eref_map_index[rf_idx]];\n- tpl_frame-\u003eref_map_index[i - LAST_FRAME] \u003d ref_picture_map[remapped_ref_idx[i- LAST_FRAME]];\n- ref_picture_map handles the map from ref slot idx to the actual frame idx in tpl\n- remapped_ref_idx[rf - LAST_FRAME] \u003d gf_group.ref_frame_list[gf_index][rf];\n\nTherefore if a block has src_stats-\u003eref_frame_index[i] \u003d\u003d X, then that\nmeans it uses ref frame stored at\ntpl_data-\u003etpl_frame[tpl_frame-\u003eref_map_index[X]], which is\ntpl_data-\u003etpl_frame[ref_picture_map[remapped_ref_idx[X]]], which is\ntpl_data-\u003etpl_frame[ref_picture_map[gf_group.ref_frame_list[gf_index][X+LAST_FRAME]]],\n\nSo that ultimately means if a block has src_stats-\u003eref_frame_index[i] \u003d\u003d\nX, then it uses ref slot\ngf_group.ref_frame_list[gf_index][X+LAST_FRAME].\n\nChange-Id: I85f758da85575f2eeb00a75811118d0155462f0e\n",
