General Functions

Libogg contains several functions which are generally useful when using Ogg streaming, whether encoding or decoding.

All the libogg specific functions are declared in "ogg/ogg.h".

These functions can be used to manipulate some of the basic elements of Ogg - streams and pages. Streams and pages are important during both the encode and decode process.

function	purpose
ogg_stream_init	Initializes an Ogg bitstream.
ogg_stream_clear	Clears the storage within the Ogg stream, but does not free the stream itself.
ogg_stream_reset	Resets the stream status to its initial position.
ogg_stream_destroy	Frees the entire Ogg stream.
ogg_stream_check	Check for asyncronous errors.
ogg_stream_eos	Indicates whether we are at the end of the stream.
ogg_page_version	Returns the version of ogg_page that this stream/page uses
ogg_page_continued	Indicates if the current page contains a continued packet from the last page.
ogg_page_packets	Indicates the number of packets contained in a page.
ogg_page_bos	Indicates if the current page is the beginning of the stream.
ogg_page_eos	Indicates if the current page is the end of the stream.
ogg_page_granulepos	Returns the precise playback location of this page.
ogg_page_serialno	Returns the unique serial number of the logical bitstream associated with this page.
ogg_page_pageno	Returns the sequential page number for this page.
ogg_packet_clear	Clears the ogg_packet structure.
ogg_page_checksum_set	Checksums an ogg_page.
