14. The video decoding device of claim 9 , wherein when a bitstream that includes the ordered set of RPLM syntax elements does not include data that indicate a particular RPLM syntax element in the ordered set of RPLM syntax elements: if the particular RPLM syntax element is the first RPLM syntax element in the ordered set of RPLM syntax elements, the one or more processors determine that a value of the particular RPLM syntax element is equal to 0, and if the particular RPLM syntax element is not the first RPLM syntax element in the ordered set of RPLM syntax elements, the one or more processors determine that a value of the particular RPLM syntax element is equal to a value of a previous RPLM syntax element in the ordered set of RPLM syntax elements plus 1, modulo a total number of current picture order count values in the initial version of the reference picture list.
9. A video decoding device comprising: a storage medium configured to store video data; and one or more processors configured to: generate an initial version of a reference picture list; determine that a reference picture list modification (RPLM) syntax element is a last RPLM syntax element in an ordered set of one or more RPLM syntax elements when the RPLM syntax element has a particular value; generate a final version of the reference picture list, wherein for each respective RPLM syntax element in the ordered set of RPLM syntax elements that does not have the particular value, the final version of the reference picture list includes, at an insertion position for the respective RPLM syntax element, a reference picture associated with the respective RPLM syntax element, wherein the respective RPLM syntax element indicates a position in the initial version of the reference picture list of the reference picture associated with the respective RPLM syntax element, and wherein the insertion position for the respective RPLM syntax element corresponds to a position in the ordered set of RPLM syntax elements of the respective RPLM syntax element; and decode, based on a reference picture in the reference picture list, a block of the video data.
