Abstract

As one example techniques for decoding video data include receiving a bitstream that includes one or more pictures of a coded video sequence (CVS) decoding a first picture according to a decoding order wherein the first picture is a random access point (RAP) picture that is not an instantaneous decoding refresh (IDR) picture and decoding at least one other picture following the first picture according to the decoding order based on the decoded first picture. As another example techniques for encoding video data include generating a bitstream that includes one or more pictures of a CVS wherein a first picture according to the decoding order is a RAP picture that is not an IDR picture and avoiding including at least one other picture other than the first picture that corresponds to a leading picture associated with the first picture in the bitstream.
