For the first coefficient (DC, unless block type is 0), we look at the (already encoded) blocks above and to the left of the current block. The context index is then the number (0,1,or 2) of these blocks having nonzero coefficients. After decoding a coefficient, the measure is determined by the size of the most recently decoded coefficient. Note that the intuitive meaning of this measure changes as coefficients are decoded, e.g., prior to the first token, a zero means that my neighbors are empty while, after the first token, because of the use of end-of-block, a zero means we just decoded a zero and hence guarantees that a non-zero coefficient will appear later in this block. However, this shift in meaning is perfectly OK because our context depends also on the coefficient band (and since zigzag positions 0, 1, and 2 are in distinct bands). */ #define CODEC_VP9_PREV_COEF_CONTEXTS 6 #define CODEC_VP9_MBSKIP_CONTEXTS 3 #define CODEC_VP9_INTER_MODE_CONTEXTS 7 #define CODEC_VP9_INTER_MODES 4 //NEAREST_MV, NEAR_MV, ZERO_MV, NEW_MV #define CODEC_VP9_SWITCHABLE_FILTERS 3 // number of switchable filters #define CODEC_VP9_INTRA_INTER_CONTEXTS 4 #define CODEC_VP9_COMP_INTER_CONTEXTS 5 #define CODEC_VP9_REF_CONTEXTS 5 #define CODEC_VP9_BLOCK_SIZE_GROUPS 4 #define CODEC_VP9_INTRA_MODES 10 //DC_PRED,V_PRED,H_PRED,D45_PRED,D135_PRED,D117_PRED,D153_PRED,D207_PRED,D63_PRED,TM_PRED #define CODEC_VP9_PARTITION_PLOFFSET 4 // number of probability models per block size #define CODECHAL_VP9_PARTITION_CONTEXTS (4 * CODEC_VP9_PARTITION_PLOFFSET) #define CODEC_VP9_MV_JOINTS 4 #define CODEC_VP9_MV_CLASSES 11 #define CODEC_VP9_CLASS0_BITS 1 /* bits at integer precision for class 0 */ #define CODECHAL_VP9_CLASS0_SIZE (1 << CODEC_VP9_CLASS0_BITS) #define CODECHAL_VP9_MV_OFFSET_BITS (CODEC_VP9_MV_CLASSES + CODEC_VP9_CLASS0_BITS - 2) #define CODEC_VP9_MV_FP_SIZE 4 #define CODEC_VP9_NUM_REF_FRAMES_LOG2 3 #define CODEC_VP9_NUM_REF_FRAMES (1 << CODEC_VP9_NUM_REF_FRAMES_LOG2) #define CODECHAL_VP9_NUM_DPB_BUFFERS (CODEC_VP9_NUM_REF_FRAMES + 4) #define CODEC_VP9_NUM_CONTEXTS 4 #define CODEC_VP9_MAX_REF_LF_DELTAS 4 #define CODEC_VP9_MAX_MODE_LF_DELTAS 2 #define CODECHAL_VP9_SEG_TREE_PROBS (CODEC_VP9_MAX_SEGMENTS - 1) #define CODEC_VP9_PREDICTION_PROBS 3 #define CODEC_VP9_MAX_LOOP_FILTER 63 #define CODEC_VP9_MAX_QP 255 #define CODEC_VP9_QINDEX_RANGE (CODEC_VP9_MAX_QP + 1) #define CODEC_VP9_MAX_REPAK_THRESHOLD 40342 //VP9 Profile typedef enum { CODEC_PROFILE_VP9_PROFILE0 = 0, CODEC_PROFILE_VP9_PROFILE1 = 1, CODEC_PROFILE_VP9_PROFILE2 = 2, CODEC_PROFILE_VP9_PROFILE3 = 3 }CODEC_VP9_PROFILE_IDC;
