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.

Abstract: An example device includes a memory configured to store video data; and one or more processors implemented in circuitry and configured to: receive tracking and sensor information from an extended reality (XR) client device; generate scene data using the tracking and sensor information, the scene data comprising one or more video frames of the video data; encode the video frames to form encoded video frames; perform a radio access network (RAN) simulation of delivering the encoded video frames via a radio access network; decode the encoded video frames delivered according to the RAN simulation to form decoded video frames; calculate values representing individual frame quality for each of the video frames from the generated one or more video frames and the decoded video frames; and determine an overall quality value from the values representing the individual frame quality for each of the video frames.

Abstract: Systems and methods for establishing a connection with an edge application server are provided. A user equipment (UE) in a wireless communication network establishes a connection with an edge application server to offload the data processing of an application executing on the UE to the edge application server. The UE communicates key performance indicators (KPIs) associated with the application to the edge data network. The KPIs indicate the resources that application uses to process the data. In response, the UE receives edge application server parameters from multiple servers in the edge data network that meet or exceed the KPIs. The parameters include compute, graphical compute, memory and storage parameters with various levels of specificity. The UE selects one of the edge application servers to process the data on behalf of the application based on the parameters.
