The present subject matter relates to point cloud encoding and decoding methods and apparatuses. A point cloud file transmitted by a data source is received. The point cloud file comprises point cloud media tracks having the same point cloud content and point cloud media tracks having different frame rates. File encapsulation information of the point cloud media tracks are parsed to obtain frame rate indication information carried in the file encapsulation information. The frame rate indication information indicates frame rates of the point cloud media tracks. A point cloud media track with a designated frame rate is selected and decoded from the point cloud file according to the frame rate indication information carried in the file encapsulation information.
