This bug is confirmed and only happens when the picture width or height is smaller than two LCUs. The fix is in TICKET_543_FIX macro as follows:
At Line 750 in TComAdaptiveLoopFilter.cpp,
for(Int i = 0; i < m_img_height; i=i+4) { #if TICKET_543_FIX yIndex = (yInterval == 0)?(3):(Clip_post( 3, i / yInterval)); #else yIndex = Clip_post( 3, i / yInterval); #endif yIndexOffset = yIndex * 4 ; for(Int j = 0; j < m_img_width; j=j+4) { #if TICKET_543_FIX xIndex = (xInterval==0)?(3):(Clip_post( 3, j / xInterval)); #else xIndex = Clip_post( 3, j / xInterval); #endif m_varImg[i>>shiftH][j>>shiftW] = regionTable[yIndexOffset + xIndex]; } }
