摘要:
A method and related apparatus for decoding an image sequence from a bitstream, wherein an identifier indicating if all output pictures are decodable with a predefined set of reference pictures is decoded; an indication of required reference pictures for a given output picture is decoded; the indicated at least one reference picture for the given output picture is decoded; and the at least one output picture is decoded.

There are disclosed methods, apparatuses and computer program products for volumetric video compression. In accordance with an embodiment, the method for encoding comprises obtaining a basic view and one or more additional views of a volumetric video content; forming patches from the basic view and one or more additional views; packing patches into one or more regions of an atlas; encoding the one or more regions of the atlas; reconstructing patches from the encoded atlas; selecting a reference view; forming residual data based on the reconstructed patches and the reference view; and encoding the residual data. In accordance with an embodiment, the method for decoding comprises decoding residual data regarding reconstructed patches and a reference view; obtaining the reference view; forming patches of an atlas from the decoding residual data and the reference view; and reconstructing a basic view and one or more additional views of a volumetric video content from the patches.

There are disclosed various methods, apparatuses and computer program products for media encapsulating and decapsulating. In an example method for encapsulating media data, a container file including at least one meta data unit in a media data structure is formed. It may be determined that an offset is relative to a location of the media data structure in the container file, wherein the offset data is formed as a reference to the location of the media data structure in the media data unit. An indication that the offset data is relative to the location of the media data structure is included. In an example method for decapsulating media data, a container file including at least one meta data unit in a media data structure and offset data are received. It may be determined that the offset data is relative to a location of the media data structure in the container file, wherein the offset data is used as a reference to the location of the media data structure to obtain the media data unit.
