Abstract:
1. A method for coding video data, the method comprising: coding information indicative of reference pictures that belong to a reference picture set, wherein the reference picture set identifies the reference pictures that can potentially be used for inter-predicting a current picture and can potentially be used for inter-predicting one or more pictures following the current picture in decoding order; constructing a plurality of reference picture subsets that each identifies zero or more of the reference pictures of the reference picture set, wherein the plurality of reference picture subsets comprises: adding reference pictures from the first reference picture subset, the second reference picture subset, and the third reference picture subset into a first set of entries in a reference picture list; determining that a number of entries in the reference picture list is not equal to a maximum number of allowable entries in the reference picture list after adding reference pictures from the first reference picture subset, the second reference picture subset, and the third reference picture subset into the first set of entries in the reference picture list; in response to determining that the number of entries in the reference picture list is not equal to the maximum number of allowable entries in the reference picture list, repeatedly re-adding one or more reference pictures from at least one of the reference picture subsets into entries in the reference picture list that are subsequent to the first set of entries until the number of entries in the reference picture list is equal to the maximum number of allowable entries in the reference picture list; and coding the current picture based on the reference picture list.
