Abstract: In an example, the present disclosure provides for receiving in a video bitstream an access unit having a first random access point (RAP) picture and receiving in the video bitstream, after the access unit in the bitstream, a subsequent access unit having a second RAP picture. In a case that one or more random access skipped leading (RASL) pictures for the subsequent access unit are not present in the received video bitstream, shifting a picture buffer removal time earlier based on a picture buffer removal delay offset. Another example provides for receiving an access unit after an earlier initialization of the hypothetical reference decoder (HRD), the access unit having a RAP picture, wherein associated access units containing RASL pictures are not received and initializing a picture buffer removal time and a picture buffer removal delay offset in response to receiving the access unit and not receiving the associated access units containing RASL pictures.

Abstract: A device obtains, from a bitstream that includes an encoded representation of the video data, a non-nested Supplemental Enhancement Information (SEI) message that is not nested within another SEI message in the bitstream. Furthermore, the device determines a layer of the bitstream to which the non-nested SEI message is applicable. The non-nested SEI message is applicable to layers for which video coding layer (VCL) network abstraction layer (NAL) units of the bitstream have layer identifiers equal to a layer identifier of a SEI NAL unit that encapsulates the non-nested SEI message. A temporal identifier of the SEI NAL unit is equal to a temporal identifier of an access unit containing the SEI NAL unit. Furthermore, the device processes, based in part on one or more syntax elements in the non-nested SEI message, video data of the layer of the bitstream to which the non-nested SEI message is applicable.

Abstract: A video coder may, in some cases, signal whether one or more initial reference picture lists are to be modified. When an initial list is to be modified, the video coder can signal information indicating a starting position in the initial reference picture list. When the starting position signaled by the video coder is less than a number of pictures included in the initial reference picture list, then the video coder signals the number of pictures to be inserted into the initial reference picture list, and a reference picture source from which a picture can be retrieved to insert into the initial reference picture list to construct a modified reference picture list.
