Separate track storage of texture and depth views for multiview coding plus depth

A device for processing video data comprising:

• a memory configured to store video data;
• and
• one or more processors configured to:
• parse a track of multiview video data, wherein the track includes one or more views, including only one of a texture view of a particular view and a depth view of the particular view;
• and
• parse a track reference to determine a dependency of the track to a referenced track indicated in the track reference, wherein parsing the track reference includes at least one of:
• parse a track reference type ‘deps’ that indicates that the track includes the depth view of the particular view and the reference track includes the texture view of the particular view,
• parse a track reference type ‘tref’ that indicates that the track depends on the texture view of the particular view which is stored in the referenced track, and
• parse a track reference type ‘dref’ that indicates that the track depends on the depth view of the particular view which is stored in the referenced track.

A non-transitory computer-readable storage medium having instructions stored thereon that upon execution cause one or more processors of a video coding device to:

• parse a track of multiview video data, wherein the track includes one or more views, including only one of a texture view of a particular view and a depth view of the particular view;
• and
• parse a track reference to determine a dependency of the track to a referenced track indicated in the track reference, wherein parsing the track reference includes at least one of:
• parse a track reference type ‘deps’ that indicates that the track includes the depth view of the particular view and the reference track includes the texture view of the particular view,
• parse a track reference type ‘tref’ that indicates that the track depends on the texture view of the particular view which is stored in the referenced track, and
• parse a track reference type ‘dref’ that indicates that the track depends on the depth view of the particular view which is stored in the referenced track.
