Abstract: A computing device generates a file that comprises a media data box that encloses media content. The media content comprises a sequence of samples. Each of the samples is an access unit of multi-layer video data. Responsive to a determination that at least one access unit of a bitstream of the multi-layer video data includes a coded picture that has a picture output flag equal to a first value and a coded picture that has a picture output flag equal to a second value, the computing device uses at least two tracks to store the bitstream in the file. For each respective track from the at least two tracks, all coded pictures in each sample of the respective track have the same value of the picture output flag.

Abstract: A prediction unit (PU) of a coding unit (CU) is split into two or more sub-PUs including a first sub-PU and a second sub-PU. A first motion vector of a first type is obtained for the first sub-PU and a second motion vector of the first type is obtained for the second sub-PU.

Abstract: A video coding device performs a disparity vector derivation process for a current block of multi-view video data. The current block is in a current view. An availability value indicates that a disparity vector for the current block is unavailable when the disparity vector derivation process is unable to derive the disparity vector for the current block. When the availability value indicates that the disparity vector derivation process has not derived the disparity vector for the current block, the video coding device generates a disparity vector for the current block in another manner.
