The matroska elements contain the spherical data in the same structure
as they are in mov files. Much like we're including oggdec.h or flac.h
to parse vorbis comment and flac headers, including a new header to
parse an specific kind of mov atom available in other formats should be

After all, the alternative would be duplicate the parsing code in two
