Abstract: An example device for decoding media data includes a memory configured to store the media data and one or more processors implemented in circuitry and communicatively coupled to the memory. The one or more processors are configured to determine whether two or more decoder instances are intended to be synchronized. The one or more processors are configured to, based on the two or more decoder instances being intended to be synchronized, control the two or more decoder instances so as to enable rendering of decoded data from each of the two or more decoder instances at a same presentation time.

Abstract: Various embodiments include systems and methods for providing an immersive three-dimensional group session. Various embodiments include methods and devices for signaling a description of a scene with media components potentially coming from different parties. In various aspects, a scene graph may be signaled through a session description protocol (SDP) during a session initiation protocol (SIP) session setup. In various embodiments, the scene graph may include respective graphical output nodes assigned to be controlled by each of the plurality of participant computing devices in an immersive three-dimensional group session.

Abstract: A device for processing media content obtains data from a box within a file conforming to a file format for a video codec, the box comprising a syntax structure that includes the data, the file being associated with the media content and the media content being coded according to the video codec; and determines, based on the data obtained from the box, whether to accept or reject the media content associated with the file. A device for generating media content generates data in a box within a file conforming to a file format, the box comprising a syntax structure that includes the data, the file being associated with the media content, wherein the data is for use in determining whether a client is to accept or reject the media content associated with the file; and outputs the file.

Abstract: An example device for processing media data is configured to parse a bitstream including the media data, the bitstream being formatted according to Common Media Application Format (CMAF), detect, during the parsing, a file type (FTYP) value for a CMAF track file of the bitstream, determine that a CMAF header of the CMAF track file starts with the FTYP value, and process one or more CMAF fragments following the CMAF header of the CMAF track file. The device may additionally be configured to detect one or more segment type (STYP) values in the bitstream, determine that each of the one or more STYP values corresponds to a start of a respective one of the CMAF fragments, and process each of the CMAF fragments starting from the corresponding STYP value.
