1. An information processing apparatus comprising:
circuitry configured to:
acquire a content including a plurality of component streams, wherein the plurality of component streams include a metadata stream;
generate content random access point (RAP) information indicating random access points of the content on a basis of random access points of the component streams of the acquired content;
generate a content file in which the content RAP information is stored in a metadata area,
wherein the content is video codec based point cloud compression (V-PCC) content, and the content file is an ISOBMFF-compliant file, and
wherein, based on the content RAP information stored in the metadata area, content RAP information of the plurality of component streams are determined; and
store a flag in a sample entry of a metadata track for the metadata stream, wherein the flag indicates that the content RAP information stored in the metadata stream is RAP information of the V-PCC content that satisfies a condition that the content RAPs are of a same type in the plurality of component streams.
