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: Techniques and systems are provided for processing video data and processing one or more media format files. For example, video data can be obtained and processed to generate a media format file that includes the video data and a restricted scheme information box associated with the video data. The restricted scheme information box includes a plurality of scheme type boxes that identify a plurality of restricted scheme types required for processing the video data. In another example, the media format file including the video data and the restricted scheme information box associated with the video data is obtained. The media format file can be parsed, and the video data can be processed according to the plurality of restricted scheme types identified by the plurality of scheme type boxes.

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.
