Error when decoding sequences with multiple sequence parameter sets

Reported by: peterderivaz Owned by:
Priority: minor Milestone: HM-10.1
Component: HM Version: HM-10.0
Keywords: Cc: fbossen, ksuehring, davidf, jct-vc@…


In TDecCavlc::parseSPS there is code to set the global variable g_uiMaxCUDepth at the line:

g_uiMaxCUDepth = uiMaxCUDepthCorrect+g_uiAddCUDepth;

However, if a bitstream contains multiple sequence parameter sets with different values for log2_diff_max_min_coding_block_size the value for the global variable may be incorrect.

This results in the error:

Assertion uiLog2TrafoSize > pcCU->getQuadtreeTULog2MinSizeInCU(uiAbsPartIdx)' failed.`

Perhaps the global variables need to be changed when the active SPS is changed?
