#36 closed defect (fixed)

max_tid_ref_present_flag=1 when no ILP is available

Reported by: Sebastiaan Owned by: Vadim

Description

When (erroneously) max_tid_ref_present_flag=1 and NumActiveRefLayers=0 for all layers (to envision a simulcast scenario) the decoder crashes at:
READ_CODE( 3, uiCode, "max_tid_il_ref_pics_plus1[i][j]" ); vps->setMaxTidIlRefPicsPlus1(i, j, uiCode);

A config parameter check forcing max_tid_ref_present_flag=0 when NumActiveRefLayers=0 for all layers can solve this issue. However, this fixes the symptoms but not the underlying problem and I'm not sure if this will not conflict with standard behaviour for different situations.
