    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.

    Abstract: A device for retrieving media data 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 the media presentation, the manifest file including data for an initialization set, the initialization set including initialization parameters for the full duration of the media presentation; initializing playback of the media data of the media presentation using the initialization set; retrieving the media data of the media presentation; and present the media data according to the initialized playback. For example, the initialization parameters may specify a maximum width or a maximum height of pictures of the media presentation or a maximum frame rate of the media presentation. Thus, the processors can process pictures of any size less than or equal to the maximum width/height, or media data equal to or less than the maximum frame rate.

    Abstract: An example device for retrieving media data includes a memory configured to store media data; and one or more processors implemented in circuitry and configured to: retrieve at least a portion of a first segment of a representation of the media data, the at least portion of the first segment including data indicating that the first segment includes a missing section representing a period of time for which media data is not available but for which a segment timeline can be extended; retrieve media data of a second segment having a presentation time following the missing section; extend the segment timeline according to the data of the at least portion of the first segment; and output the media data of the second segment according to the extended segment timeline.

    Abstract: A device for processing video data can be configured to receive a configuration record for decoding a bitstream of the video data, wherein the configuration record for the bitstream includes a toolset indication syntax element that includes information identifying, from a set of video decoding tools, tools that are required to decode the bitstream associated with the configuration record; based on the toolset indication syntax element, determine whether to retrieve the bitstream associated with the configuration record; and based on the determination to retrieve the bitstream associated with the configuration record, retrieve the bitstream and outputting the bitstream to a video decoder for decoding.

    Abstract: Embodiments include methods performed by a processor of a mobile device for allocating resources to a plurality of mobile devices in communication with an Edge network. The processor may receive from the plurality of mobile devices one or more capabilities of each mobile device related to a computing task in which the plurality of mobile devices are participating. The processor may determine a fairness result for the plurality of computing devices based on the one or more capabilities of each mobile device and the computing task. The processor may allocate resources to each of the plurality of mobile devices based on the determined fairness result.
