    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: 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: 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, for transmission to a second device, an offer message configured to establish a conference with at least the second device. The offer message includes a list of one or more concurrent codec capabilities supported by the first device. The list of one or more concurrent codec capabilities supported by the first device comprises an indication of whether or not one or more concurrent instances of a first listed codec for coding a media stream for transmission to the first device are replaceable by one or more concurrent instances of a second listed codec for coding the media stream for transmission to the first device. The method also comprises receiving, at the first device, an answer message in response to the offer message.

    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: A device includes a processor configured to process a first sample of a first track having a first composition time, determine whether a second track that is associated with the first track has an available sample at the first composition time, when the second track has the available sample at the first composition time, select the available sample of the second track as a second sample having a common composition time with the first composition time of the first sample, when the second track does not have the available sample at the first composition time, select a sample of the second track having a composition time that is a closest available preceding composition time as the second sample having the common composition time with the first composition time of the first sample, and in response to selecting the second sample, process the second sample.
