nce obeys all constraints specified in clause G.10.1.3, and constraint set3 flag equal to 0 specifies that the coded video sequence may or may not obey these corresponding constraints. Otherwise (profile_idc is not equal to 86), the value of 1 for constraint_set3_flag is reserved for future use by ITU-T ISO/IEC. constraint set shall be equal to 0 for coded video sequences with profile_idc not equal Rec. ITU-T H.264 (01/2012) to 86 in bitstreams conforming to this Recommendation | International Standard. Decoders shall ignore the value of constraint_set3_flag when profile_idc is not equal to 86. constraint_set5 is specified as follows: If the sequence parameter set data syntax structure is included in a sequence parameter set RBSP, the semantics specified in clause 7.4.2.1.1 apply. Otherwise (the sequence parameter set data syntax structure is included in a subset sequence parameter set RBSP), the following applies: If the profile_idc is equal to 83, constraint_set5_flag equal to 1 specifies that the coded video sequence obeys all constraints specified in clause G.10.1.1.1. Otherwise, if the profile_ido is equal to 86, constraint_set5_flag equal to 1 specifies that the coded video sequence obeys all constraints specified in clause G.10.1.2.1. Otherwise (profile idc is not equal to 83 or 86), the value of 1 for constraint_set5_fla is reserved for future use by ITU-T | ISO/IEC. constraint_set5_flag shall be equal to 0 for coded video sequences with profile_id not equal to 83 or 86 in bitstreams conforming to this Recommendation | International Standard. Decoders shall ignore the value of constraint_set5_flag when profile_idc is not equal to 83 or 86. The value of separate_colour_plane_flag shall be equal to 0 and the value of qpprime_y_zero_transform_bypass_flag shall be equal to 0. When the seq_parameter_set_data() syntax structure is present in a subset sequence parameter set RBSP and vui_parameters_present_flag is equal to 1, timing_info_present_flag shall be equal to al_hrd_parameters_present_ shall be equal to
