Abstract: Various embodiments include systems and methods for supporting communication session establishment (e.g., Web Real-Time Communication (WebRTC) session establishment) between endpoint computing devices. Various embodiments include systems and methods that may provide for a server (e.g., a Simple WebRTC Application Protocol (SWAP) server acting as a WebRTC signaling server) that protects message privacy and integrity between endpoint computing devices by acting as a rendezvous point for applications and services. Various embodiments include systems and methods defining a simple, secure, and extensible signaling protocol that may allow a receiving party to determine and control other parties that may connect to the receiving party via communication session (e.g., a WebRTC session).

Abstract: Systems, methods, and computer-readable storage media are provided for decoded picture buffer (DPB) operations and rewriting access unit delimiters (AUDs) after bitstream extractions. An example method can include storing one or more pictures associated with an access unit (AU) in a decoded picture buffer (DPB), the AU including a first plurality of pictures, the first plurality of pictures corresponding to a plurality of video coding layers; after each picture of a second plurality of pictures associated with the AU is removed from a coded picture buffer (CPB), removing at least one picture of the one or more pictures from the DPB; and storing, in the DPB, each picture of the second plurality of pictures removed from the CPB.

Abstract: Systems and techniques are described herein for processing video data. For instance, a process can include obtaining video data including a picture. The process can also include determining a width of a film grain synthesis block of the picture based on at least one of a width and a height of the picture. The process can further include determining a height of the film grain synthesis block of the picture is one. The process may also include determining a block size of the film grain synthesis block based on the determined width and height. The process may further include selecting a grain block based on the determined block size.

Abstract: Disclosed are systems, methods, apparatuses, and computer-readable media for processing video data. For instance, an apparatus for processing video data, may include: at least one memory; and at least one processor coupled to the at least one memory, the at least one processor being configured to: obtain a bitstream; retrieve a granularity type syntax element associated with the bitstream, the granularity type syntax element specifying a type of granularity of one or more pictures over which complexity metrics (CM) associated with the bitstream are applicable; retrieve a period type syntax element associated with the bitstream, the period type syntax element indicating an upcoming period of time or a set of pictures over which the CM are applicable; and decode a portion of the bitstream based on the granularity type syntax element and the period type syntax element.
