* The page struct encapsulates the data for an Ogg page. * * Ogg pages are the fundamental unit of framing and interleave in an ogg * bitstream. They are made up of packet segments of 255 bytes each. There can * be as many as 255 packet segments per page, for a maximum page size of a * little under 64 kB. This is not a practical limitation as the segments can be * joined across page boundaries allowing packets of arbitrary size. In practice * pages are usually around 4 kB.

type t = string * string

A page is a header and a body

val serialno : t -> nativeint

* Returns the unique serial number for the logical bitstream of this page. * Each page contains the serial number for the logical bitstream that it belongs to.

val eos : t -> bool

* Indicates whether this page is at the end of the logical bitstream.

val bos : t -> bool

* Indicates whether this page is at the begining of the logical bitstream.

val continued : t -> bool

* Indicates whether this page contains packet data which has been * continued from the previous page.

val packets : t -> int

* Returns the number of packets that are completed on this page. * If the leading packet is begun on a previous page, but ends on this page, it's counted. * * If a page consists of a packet begun on a previous page, and a new packet begun * (but not completed) on this page, the return will be: * * packets page will return 1, * continued paged will return true * * If a page happens to be a single packet that was begun on a previous page, * and spans to the next page (in the case of a three or more page packet), the return will be: * * packets page will return 0, * continued page will return true.

val version : t -> int

* This function returns the version of ogg_page used in this page. * In current versions of libogg, all ogg_page structs have the same version, * so 0 should always be returned.

val granulepos : t -> Stdlib.Int64.t

* Returns the exact granular position of the packet data contained at the end of this page. * * This is useful for tracking location when seeking or decoding. * * For example, in audio codecs this position is the pcm sample number and * in video this is the frame number.

val pageno : t -> nativeint

* Returns the sequential page number. * * This is useful for ordering pages or determining when pages have been lost.

val set_checksum : t -> unit

* Checksums an ogg_page.
