1. A method of encoding video data, the method comprising:
encoding a future intra random access point (IRAP) picture of video data having a first display order position, the future IRAP picture being included in an intra period (IP) of the video data, the IP comprising a plurality of groups of pictures (GOPs) and a plurality of IRAP pictures including the future IRAP picture; and
after encoding the future IRAP picture, encoding a picture of an ordinal first GOP of the plurality of GOPs using the future IRAP picture as a reference picture, each picture of the ordinal first GOP having display order positions earlier than the first display order position, the future IRAP picture being beyond a GOP boundary of the ordinal first GOP.
