Abstract: A device configured to process a bitstream may implement the techniques. The device comprises a memory configured to store the bitstream representative of at least one audio element in an extended reality scene, and audio descriptive information associated with the at least one audio element. The device also comprises processing circuitry coupled to the memory and configured to execute a scene manager and an audio unit. The scene manager is configured to construct, based on the at least one audio element, a scene graph that includes at least one node that represents the at least one audio element, and modify, based on the scene graph, the audio descriptive information to obtain modified audio descriptive information. The audio unit is configured to render, based on the modified audio descriptive information, the at least one audio element to one or more speaker feeds, and output the one or more speaker feeds.

Abstract: Techniques are provided for processing media content. For example, a process can include using a scene description for to obtain media information and buffer information for a media object. The media information can identify an expected format for storing the media object in one or more output buffers of a media pipeline. The buffer information can include output buffer attributes. The process can include using the media information and the buffer information to initialize the media pipeline for the media object. The process can include obtaining the media object in a delivery format and generating one or more processed media objects. Each processed media object can be converted from the delivery format to the expected format for storing the processed media object in an output buffer. The process can include outputting the processed media object(s) to the output buffer(s) using the initialized media pipeline.

Abstract: A device for retrieving media includes a memory configured to store media data of a media presentation; and one or more processors implemented in circuitry and configured to: retrieve a manifest file for a media presentation indicating that container parsing of media data of a bitstream can be started at a resync point of a segment of a representation of the media presentation, the resync point being at a position other than a start of the segment and representing a point at which the container parsing of the media data of the bitstream can be started; use the manifest file to form a request to retrieve the media data of the representation starting at the resync point; send the request to initiate retrieval of the media data of the media presentation starting at the resync point; and present the retrieved media data.
