Description
at the beginning of SPS syntax table,
In latest spec (Q0041)
sps_max_sublayers_minus1 u(3)
sps_reserved_zero_4bits u(4)
sps_ptl_dpb_hrd_params_present_flag u(1)
if( sps_ptl_dpb_hrd_params_present_flag )
profile_tier_level( 1, sps_max_sublayers_minus1 )
However, in latest commit of VTM (65e585026d) parseSPS()
the parsing syntax corresponding to the follows
sps_max_sub_layers_minus1 u(3)
sps_reserved_zero_5bits u(5)
profile_tier_level( ptl, sps_max_sub_layers_minus1 )
VTM has
sps_reserved_zero_5bit instead of sps_reserved_zero_4bit.
no parsing for syntax sps_ptl_dpb_hrd_params_present_flag,
and the invocation of profile_tier_level() is unconditional.
