Abstract: In one example, a device for decoding video data includes a video decoder configured to decode one or more syntax elements of a current reference picture set (RPS) prediction data structure, wherein at least one of the syntax elements represents a picture order count (POC) difference between a POC value associated with the current RPS and a POC value associated with a previously decoded RPS, form a current RPS based at least in part on the RPS prediction data structure and the previously decoded RPS, and decode one or more pictures using the current RPS. A video encoder may be configured to perform a substantially similar process during video encoding.

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: Techniques of this disclosure provide an indication of whether a parameter set update can occur in a portion of a bitstream. The indication may enable a video decoder to determine whether an update of a stored parameter set can occur without performing a content comparison between the stored parameter set and a new parameter set of the same type with the same identification value. A parameter set update includes storing a current parameter set with a given identification value to replace a previous parameter set of the same type and having the same identification value. When a parameter set update cannot occur, the video decoder may store and activate a single parameter set of a given type for the entire portion of the bitstream. When a parameter set update can occur, the video decoder may automatically update a stored parameter set, or may determine whether to update the stored parameter.

Abstract translation: 本公开的技术提供了参数集更新是否可以在比特流的一部分中发生的指示。 该指示可以使得视频解码器可以确定是否可以发生存储的参数集的更新，而不执行存储的参数集与具有相同标识值的相同类型的新参数集之间的内容比较。 参数集更新包括存储具有给定标识值的当前参数集以替换相同类型的并且具有相同标识值的先前参数集。 当不能发生参数集更新时，视频解码器可存储和激活针对比特流的整个部分的给定类型的单个参数集。 当可能发生参数集更新时，视频解码器可以自动更新存储的参数集，或者可以确定是否更新所存储的参数。

Abstract: File formats and parsing and coding of video data are defined to promote more efficient random accessibility of coded video data. Constraints may be imposed on placement of parameter sets and the definition of sync samples in video files. Parameter set data for video data may be coded, for a non-sync sample, only in the sample entry for the sample, the sample, a previous sample in decoding order that is a sync sample, or in a sample occurring in decoding order between the sample and the previous sample in decoding order that is a sync sample.
