This is a minor bug with the state of uiPOC in TAppDecTop.cpp The variable is unitialized and causes it to go out of state after the first frame is decoded. Initializing it to -1 is a temporary fix as the value is no longer an unsigned integer but doing so keeps it in order with the frame just decoded as seen later

In Table 9-4, init range of last_significant_coeff_x_prefix and last_significant_coeff_y_prefix for initType=2 should be 36..53 instead of 36..54 (to be consistent with Table 9-26 and 9-27)

In section 9.3.3.1.5., "coeff_abs_greater1_flag" should be "coeff_abs_level_greater1_flag"

8.7.2.1 Derivation process of transform block boundary

Specify edgeFlags also as an input to the process.

trafoDepth1 -> trafoDepth

8.7.2.2 Derivation process of prediction block boundary

Specify edgeFlags also as an input to the process.

8.7.2.4.2 Horizontal edge filtering process

for chroma:

For xDk set equal to k << 2, k = 0..nD*2 − 1, the following applies. -> For xDk set equal to k << 2, k = 0..nD − 1, the following applies.

8.7.2.4.3 Decision process for luma block edges

dqp -> dpq (in 3 places)

8.7.2.4.4 Filtering process for luma block edges

the locations ( xC + xB +i, yC + yB + k ), ( xC + xB - i - 1, yC + yB + k ) -> the locations ( xC + xB - i - 1, yC + yB + k ), ( xC + xB +i, yC + yB + k )

(parameters are swapped; more accurate would be to explicitly assign actual to formal arguments whenever they have different names or the actual argument is an expression)

for EDGE_VER:

recPictureL[ xC + xB + k ][ yC + yB − i − 1 ] = pi’ (8 299) -> recPictureL[ xC + xB − i − 1 ][ yC + yB + k ] = pi’ (8 299) and

recPictureL[ xC + xB + k ][ yC + yB + j ] = qj’ (8 300) -> recPictureL[ xC + xB + j ][ yC + yB + k ] = qj’ (8 300)

8.7.2.4.5 Filtering process for chroma block edges

Input bS could be removed, it is always equal to 2.

slice_cb_qp_offset or slice_cb_qp_offset -> slice_cb_qp_offset or slice_cr_qp_offset

8.7.2.4.6 Decision process for a luma sample

i = 0..3 -> i = 0, 3 (pi and qi with i = 1, 2 are not used)

8.7.2.4.7 Filtering process for a luma sample

When nDp is greater than 0 and one or more of the following conditions are true for i = 0..nDp-1, nDp is set equal to 0 -> When nDp is greater than 0 and one or more of the following conditions are true for i = 0, nDp is set equal to 0 (the conditions for i > 0 do not differ from those for i = 0). Same for nDq.
