stituent frame 1, and the display time of the constituent frame 0 should be delayed to coincide with the display time of constituent frame 1. current_frame_is_frame0_flag equal to 0, when frame_packing_arrangement is equal to 5, indicates that the current decoded frame is constituent frame 1 and the previous decoded frame in output order is constituent frame 0, and the display time of the constituent frame 1 should not be delayed for purposes of stereo-view pairing. When frame_packing_arrangement_typ is not equal to 5, the constituent frame associated with the upper-left sample of the decoded frame is considered to be consitutuent frame 0 and the other constituent frame is considered to be constituent frame 1. When frame_packing_arrangement_type is not equal to 5, it is a requirement of bitstream conformance that current_frame_is_frame0_flag shall be equal to 0. When frame_packing_arrangement_typeis not equal to 5, the value 1 for current_frame_is_frame0_flag is reserved for future use by ITU-T | ISO/IEC. When frame_packing arrangement_type is not equal to 5, decoders shall ignore the value of current_frame_is_frame0_flag. frame0_self_contained_flag equal to 1 indicates that no inter prediction operations within the decoding process for the samples of constituent frame 0 of the coded video sequence refer to samples of any constituent frame 1. frame0_self_contained_flag equal to 0 indicates that some inter prediction operations within the decoding process for the samples of constituent frame 0 of the coded video sequence may or may not refer to samples of some constituent frame 1. When frame_packing_arrangement_type is equal to 0 or 1, it is a requirement of bitstream conformance that frame0_self_contained_flag shall be equal to 0. When frame_packing_arrangement_type is equal to 0 or 1, the value Rec. ITU-T H.264 (01/2012) for frame0_self_contained_flag is reserved for future use by ITU-T | ISO/IEC. When frame_packing_arrangement_type is equal to 0 or 1, decoders shall ignore the value of frame0_self_contained_fla
