Description

At 7.3.8.8 Transform tree syntax, the condition for cbf_cb / cbf_cr,
the condition " if ( trafoDepth == 0 | | log2TrafoSize > 2 ) " is present.
However, if trafoDepth is equal to "0", log2TrafoSize is always greater than and equal to "3".

Replace
if( trafoDepth == 0 | | log2TrafoSize > 2 ){

if( trafoDepth == 0 | | cbf_cb[ xBase ][ yBase ][ trafoDepth - 1 ] )

cbf_cb[ x0 ][ y0 ][ trafoDepth ]

if( trafoDepth == 0 | | cbf_cr[ xBase ][ yBase ][ trafoDepth - 1 ] )

cbf_cr[ x0 ][ y0 ][ trafoDepth ]

}
by
if( log2TrafoSize > 2 ) {

if( trafoDepth == 0 | | cbf_cb[ xBase ][ yBase ][ trafoDepth - 1 ] )

cbf_cb[ x0 ][ y0 ][ trafoDepth ]

if( trafoDepth == 0 | | cbf_cr[ xBase ][ yBase ][ trafoDepth - 1 ] )

cbf_cr[ x0 ][ y0 ][ trafoDepth ]

}
