Methods and apparatus for using track derivations for network based media processing

An apparatus configured to process video data, the apparatus comprising a processor in communication with memory, the processor being configured to execute instructions stored in the memory that cause the processor to:

• receive, from a remote computing device, multi-view multimedia data comprising a hierarchical track structure comprising at least:
• a first track comprising first media data at a first level of the hierarchical track structure;
• and
• metadata associated with a second track at a second level in the hierarchical track structure that is different than the first level of the first track;
• and
• process the first media data of the first track based on the metadata associated with the second track to generate second media data for the second track.

At least one computer readable storage medium storing processor-executable instructions that, when executed by at least one processor, cause the at least one processor to perform:

• receiving, from a remote computing device, multi-view multimedia data comprising a hierarchical track structure comprising at least:
• a first track comprising first media data at a first level of the hierarchical track structure;
• and
• metadata associated with a second track at a second level in the hierarchical track structure that is different than the first level of the first track;
• and
• processing the first media data of the first track based on the metadata associated with the second track to generate second media data for the second track.
