Data Fields
int * anchor_frames_list anchor frame list for large scale tile For large scale tile applications, the anchor frames could come from previously decoded frames in current sequence (aka. internal), or from external sources. For external anchor frames, application should call API vaCreateBuffer() to generate frame buffers and populate them with pixel frames. And this process may happen multiple times. The array anchor_frames_list[] is used to register all the available anchor frames from both external and internal, up to the current frame instance. If a previously registerred anchor frame is no longer needed, it should be removed from the list. But it does not prevent applications from relacing the frame buffer with new anchor frames. Please note that the internal anchor frames may not still be present in the current DPB buffer. But if it is in the anchor_frames_list[], it should not be replaced with other frames or removed from memory until it is not shown in the list. This number of entries of the list is given by parameter anchor_frames_num.
uint8_t anchor_frames_num number of anchor frames for large scale tile This parameter gives the number of entries of anchor_frames_list[]. Value range [0..128].
uint8_t base_qindex quantization

Y AC index value range [0..255]

uint8_t bit_depth_idx bit depth index value range [0..2] 0 - bit depth 8; 1 - bit depth 10; 2 - bit depth 12;
uint8_t cdef_bits
uint8_t cdef_damping_minus_3 CDEF parameters.
uint8_t cdef_uv_strengths[8]
uint8_t cdef_y_strengths[8]

Encode cdef strength:

The cdef_y_strengths[] and cdef_uv_strengths[] are expected to be packed with both primary and secondary strength. The secondary strength is given in the lower two bits and the primary strength is given in the next four bits.

cdef_y_strengths[] & cdef_uv_strengths[] should be derived as: (cdef_y_strengths[]) = (cdef_y_pri_strength[] << 2) | (cdef_y_sec_strength[] & 0x03) (cdef_uv_strengths[]) = (cdef_uv_pri_strength[] << 2) | (cdef_uv_sec_strength[] & 0x03) In which, cdef_y_pri_strength[]/cdef_y_sec_strength[]/cdef_uv_pri_strength[]/cdef_uv_sec_strength[] are variables defined in AV1 Spec 5.9.19. The cdef_y_strengths[] & cdef_uv_strengths[] are corresponding to LIBAOM variables cm->cdef_strengths[] & cm->cdef_uv_strengths[] respectively.

uint8_t ref_frame_idx[7] Reference frame indices.

The indices of the array are defined as [LAST_FRAME – LAST_FRAME, LAST2_FRAME – LAST_FRAME, …, ALTREF_FRAME – LAST_FRAME], where each symbol is defined as: enum{INTRA_FRAME = 0, LAST_FRAME, LAST2_FRAME, LAST3_FRAME, GOLDEN_FRAME, BWDREF_FRAME, ALTREF2_FRAME, ALTREF_FRAME};

int ref_frame_map[8] Surface indices of reference frames in DPB.

Contains a list of uncompressed frame buffer surface indices as references. Application needs to make sure all the entries point to valid frames except for intra frames by checking ref_frame_id[]. If missing frame is identified, application may choose to perform error recovery by pointing problematic index to an alternative frame buffer. Driver is not responsible to validate reference frames' id.
