Abstract: Methods and apparatus are disclosed for session initiation in a conference. In one aspect, a method for communicating between multiple parties is disclosed. The method comprises generating, at a first device, a first message for transmission to a second device. The method further comprises receiving, at the first device, a second message for establishing a conference. The second message includes a list of one or more concurrent codec capabilities supported by the second device. The list of one or more concurrent codec capabilities supported by the second device comprises an indication of whether one or more resources usable for one or more concurrent instances of a first listed codec may instead be used for one or more concurrent instances of a second listed codec.

Abstract: In various implementations, modifications and/or additions to the ISOBMFF can indicate that a file that has been formatted according to the ISOBMFF, or a format derived from the ISOBMFF, includes virtual reality content. The file can include a restricted scheme information box, written into a track box in the file. The restricted scheme information box can indicate a virtual reality scheme for the contents of the track. For example, a signaling mechanism may indicate a most-viewed viewport associated with the virtual reality data.

Abstract: Techniques and systems are provided for processing video data. In one example, a media file associated with 360-degree video data can be obtained. The 360-degree video data may include a spherical representation of a scene. The media file may include first signaling information and second signaling information of a viewport region corresponding to a region of interest (ROI) in the spherical representation. The first signaling information may include a center position and a dimension of the viewport region measured in a spherical space associated with the spherical representation. The second signaling information may indicate a region of a picture comprising the viewport region, the picture being formed by projecting the spherical representation including the ROI onto a plane. Pixels corresponding to the viewport region from the data of the picture can be extracted based on the first signaling information and second signaling information, and can be provided for rendering.

Abstract: Systems, methods, and computer readable media are described for generating a regional nesting message. In some examples, a video bitstream is obtained and an encoded video bitstream is generated using the video data. The encoded video bitstream includes a regional nesting message that contains a plurality of nested messages and region data defining at least a first region of a picture of the encoded video bitstream. For example, a first nested message of the regional nesting message includes a first set of data and a first region identifier indicating the first region of the picture is associated with the first set of data.

Abstract: An example device for processing video data includes a memory configured to store an omnidirectional video stream, and a processor implemented in circuitry and configured to process (e.g., encode, transmit, receive, or decode) a first frame of a set of file format samples of the omnidirectional video stream, the set of file format samples referring to a sample entry, the first frame having a first region-wise packing scheme, and process a second frame of the set of file format samples referring to the sample entry, the second frame having a second region-wise packing scheme different than the first region-wise packing scheme. In this manner, a single omnidirectional video bitstream may include an entire virtual reality (VR) video content with most-requested regions being optimized with a largest number of color samples per unit of area.
