1. A method for decoding video data, executable by a processor, comprising:
receiving coded video data including a coded current picture and one or more subsequent pictures;
checking a first flag for indicating whether the coded current picture is referenced for compensation or parameter prediction by the one or more subsequent pictures in a decoding order;
checking a second flag for indicating whether the coded current picture can be cropped and outputted for display or other purposes, the second flag being different from the first flag; and
decoding the coded video data at least in part by discarding the coded current picture from the coded video data based on the first flag indicating a lack of use of the coded current picture as a reference picture and the second flag indicating a restriction preventing output of the coded current picture,
wherein the first flag and the second flag are signaled in one of a picture header and a slice header associated with the video data, and
wherein a value of the second flag is inferred during decoding based on a value of the first flag.
