MULTI-LAYER VIDEO FILE FORMAT DESIGNS

摘要

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.

1. A method of processing multi-layer video data, the method comprising:
generating a file that comprises a media data box that encloses media content, the media content comprising a sequence of samples, each of the samples being an access unit of the multi-layer video data, wherein generating the file comprises:
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, using at least a first track and a second track to store the bitstream in the file, wherein:
for each respective track from the first and second tracks, all coded pictures in each sample of the respective track have the same value of the picture output flag; andpictures having picture output flags equal to the first value are allowed to be output and pictures having picture output flags equal to the second value are allowed to be used as reference pictures but are not allowed to be output.
